There are a lot of things we love about our company: an incredible culture of trust and growth, amazing team members, and the opportunity to partner with some top-notch businesses are just a few.

In honor of the 4th of July, we want to take a second to say how much we love being committed to creating our products right here on American soil. There are several compelling reasons to choose American-made products. Here are just a few of our favorites:

 

Create Jobs

American-made goods provide valuable jobs to community members. If each American spent just an additional $3.33 each week on U.S. made products, it would create 10,000 new jobs! Can you imagine how many new jobs would be created if we committed to purchasing mostly American-made products?

 

Build Community

U.S. run businesses strengthen communities. They rely on local labor, electricians, plumbers, etc. to keep their business running smoothly. Additionally, as mentioned above, they provide jobs to local community members. 

 

Lower Carbon Footprint

Cargo ships produce an incredible amount of pollution. In fact, just a few cargo ships are to blame for most of the earth’s pollution. When goods are made in the U.S., they don’t need to be shipped across the sea to reach the American consumer. 

 

Additionally, American production facilities  must meet strict environmental regulations. Environmental regulations are often lacking in developing countries where companies typically outsource production.  

 

Provide Safe Working Conditions

American businesses are held to high standards when it comes to employee safety. Operations are expected to treat team members fairly and provide safe working conditions. 

 

Increased Product Quality

U.S.-made products must meet carefully regulated safety standards. The label “made in the U.S.A.” seems to offer an unspoken assurance that a product is high-quality and built to last. 

 

Powerblanket: Made in America

Our commitment to produce our products in the U.S. has yielded incredible results. Most notably, we’ve loved the opportunity we’ve had to connect with our community and employ some incredible, hard-working team members. Each person on our team has an incredible story and we love that our product gives each team member the opportunity to work, provide for their families, and reach their goals. 

An In-Depth Look at CBD

Cannabidiol (CBD) is one of 113 known cannabinoids found in cannabis plants. While CBD as we know it has been around for over 70 years, it has recently skyrocketed in attention and popularity. Unlike THC (another cannabinoid found in cannabis plants), CBD does not cause an altered mental state and may even have huge potential for medical applications. While limited research has been done on CBD, many are hopeful that as research progresses, CBD will become a more readily-available treatment option for issues like epilepsy, pain management, anxiety, depression, and even cancer.

Plant extract oil and plants- CBD is a plant extract from cannabis plants

What is a Cannabinoid?

A cannabinoid is a chemical compound that acts on cannabinoid receptors in cells and alter a neurotransmitter release in the brain. Cannabinoids fall under two categories: endocannabinoids and phytocannabinoids.

Endocannabinoids

Endocannabinoids are produced naturally in our bodies and are believed to help regulate important neurological functions. The endocannabinoid system has only recently been recognized for its importance and relatively little is known about it.

Phytocannabinoids

Phytocannabinoids occur naturally in plants. Limited research indicates that phytocannabinoids could help resolve issues that come from endocannabinoid imbalances. Phytocannabinoids are extracted from cannabis plants (marijuana and hemp). The predominate cannabinoids found in cannabis plants are THC and CBD.

 

Cannabis Plants: Marijuana vs. Hemp

Often, the terms “cannabis”, “marijuana”, and “hemp”, are used interchangeably. It is, however, important to understand the differences between the three. “Cannabis” is the family classification that marijuana and hemp fall under. While marijuana and hemp share some similarities, there are some crucial differences between the two. Most notably, while marijuana strains are typically between 15 and 40% Tetrahydrocannabinol  (THC), hemp is less than 0.3% THC. The bulk of hemp’s composition is CBD, accounting for approximately 40% of the plant’s extract.

THC vs. CBD

CBD vs THC

THC and CBD are the predominant cannabinoids found in cannabis plants. Put simply, THC gets you “high,” while CBD is thought to provide more medical applications.

 

THC

THC is the most potent psychotic found in cannabis plants. As mentioned above, it’s found in higher percentages in marijuana. Besides giving you  a “high,” THC can cause feelings of lethargy and dysphoria and may even make anxiety and seizures worse.

 

CBD

CBD does not have intoxicating effects like THC. CBD oil is often used to treat epilepsy and pain. Some claim that CBD relives sleep issues, depression, anxiety, and other mental health disorders. It may even counteract the psychoactive effects of THC. CBD usage has been linked with side effects like decreased appetite, fatigue, weakness and sleeping problems.

 

A Brief History of CBD

 

While CBD awareness and interest has skyrocketed in recent years, CBD as we know it has been around for over 70 years. Let’s take a quick look it’s history:

 

1940: CBD was first extracted by chemist Roger Adams. It wasn’t until a few years later, however, that Roger Adams realized he may have stumbled upon something useful and began performing further research on the substance.

 

1946: Dr. Walter S. Loewe conducted tests that supported the theory that CBD didn’t cause an altered mental state.

 

1946: Dr. Raphael Mechoulam documented CBD’s three-dimensional structure. Mechoulan is often credited as the scientist who discovered CBD.

 

1960s: The first CBD oil designed for therapeutic use was released by the British Pharmacopoeia

 

1980: Dr. Raphael Mechoulam conducted research that supported the theory that CBD could treat epilepsy.

 

2013: Charlotte Figi, a girl who suffered from chronic seizures, all but eliminated her seizures using high-CBD strain cannabis; her story gained national attention.

 

2017: the FDA advisory panel approved the CBD medication Epidiolex to treat two forms of childhood epilepsy.

 

CBD Today

 

Limited Evidence

Some experts say that evidence for CBD’s benefits is scant. Most claimed benefits of CBD have only been evaluated by one or two human studies and most studies do not compare results to a control group. Some researchers argue that any beneficial effects could simply be a placebo. Furthermore, it’s unclear which specific biochemical interactions are affected by CBD.

This scant evidence, however, is not necessarily because CBD is ineffective; there simply hasn’t been enough reputable research conducted. Many are confident that continued CBD research will confirm the widespread claims of its medicinal potential.

 

What CBD is Used For

What does CBD do? Some of the benefits of CBD

Throughout the world, CBD users claim the phytocannabinoid helps alleviate issues and symptoms like pain, inflammation, anxiety, depression, psychosis, antibiotic-resistant infections, epilepsy, and other neurological disorders. Let’s take a look and some of the most common symptoms CBD is used to treat and the research backing its effectiveness:

 

Epilepsy- Epilepsy is the only condition with significant scientific evidence that supports CBD as a viable treatment option. Three separate clinical trials have indicated that pharmaceutical-grade CBD reduces seizures with minimal side effects. The CBD-based medication Epidiolex is currently used to treat two rare forms of epilepsy: Lennox-Gastaut syndrome and Dravet syndrome.

 

Pain/Inflammation- While there hasn’t been enough human trials to confirm CBD’s effect on pain and inflammation, animal trials indicate it could be a successful treatment. Some research has found that CBD reduced levels of chronic inflammation in rats and mice.

 

Anxiety- Some human clinical trials suggest that CBD could be an effective treatment for anxiety disorders including generalized anxiety disorder, panic disorder, social anxiety disorder, obsessive–compulsive disorder, and post-traumatic stress disorder.

 

Cancer- An article published in the British Journal of Clinical Pharmacology that CBD can prevent cancer cells from spreading. While more research is needed to further support this claim, CBD’s anti-cancer properties are currently being researched throughout the United States.

 

Legality

 

While CBD is legal across the US, states have varying limitations on its use. Where limitations exist, the most important factor in determining legality is whether the CBD is extracted from hemp or marijuana.

 

Even though CBD is legal, lack of regulation can make it difficult and sometimes unsafe to use. Besides Epidiolex, a CBD epilepsy medication, no forms of cannabis are recognized by the FDA. This means that CBD supplements and products are produced without regulation. CBD users must take care to purchase CBD from a reputable distributor; labels may not have the correct information about actual CBD content.

 

Extraction

 

The goal of CBD extraction is to generate a high-concentrate CBD product for potential beneficial use.

 

Timothy Welty, chair of the department of clinical sciences at Drake University’s College of Pharmacy and Health Sciences, in Des Moines, Iowa, explains that “CBD is kind of a tricky drug because it’s not very well absorbed orally. Less than 20 percent of the drug is absorbed orally. If it isn’t made in the right way, you may not be getting much drug into your systemic circulation.”

 

CBD Extraction begins with CBD-rich plant material. There are a few different methods for extracting the phytocannabinoids (including CBD) from the plant trimmings. Here are a few of the more popular methods:

 

CO2 Extraction

the CO2 extraction method for CBD extraction

The CO2 Extraction method uses pressurized carbon dioxide to pull phytochemicals from cannabis plants. While this method is extremely effective in producing high-quality CBD oil, it requires expensive machinery and the hand of an experienced chemist.  

First, CO2  gas is turned into a liquid; this is done by dropping the temperature to under -69°F and increasing the pressure to over 75 psi. Next, the temperature and pressure are both raised until the liquid becomes supercritical. Supercritical liquids possess qualities of both a liquid and a gas. This state is ideal for phytochemical extraction because:

  1. Supercritical CO2 can move through materials like gas and
  2. Supercritical CO2 can dissolve materials like a liquid

 

The supercritical CO2 passes through cannabis trimmings in an extraction chamber where it dissolves and collects extracts from the plants. The CO2 / extract solution then enters a lower-pressure separator chamber. The lower pressure causes the CO2  and plant extracts to separate. The CO2 returns to the CO2 chamber and the cannabis oil is drained from the separator.

 

Solvent Extraction

The solvent extraction method for CBD extraction

This simple extraction method works by using ethanol as a solvent to remove extracts from cannabis plant trimmings. While fairly easy, this method can be dangerous (ethanol is extremely flammable) and potentially damage or create harmful toxins within the cannabis extract.

 

First, ethanol is added to trimmings and mixed for a couple of minutes to allow the ethanol to dissolve extracts from the plant materials. Next, the ethanol is strained from the trimmings. Finally, the ethanol/extract mixture is slowly heated until all ethanol evaporates and only the plant extracts remain.

 

Dry Ice/ Ice Water Method

The Ice Water extraction method for CBD extraction

Ice water extraction creates a powdery resin extract often referred to as “hash” or “bubble hash.” This is another fairly easy extraction method that can produce high yields if done correctly. As with other methods, if done poorly, it will produce low-quality product.

 

First, finely-chopped plant trimmings are mixed with either ice or dry ice. This step is supposed to help separate extracts from the plant material. Next, water is added to the ice and trimmings and the entire mixture is strained through a mesh bag. The extracts will settle to the bottom of the strained water. Often, the mixture is strained multiple times through progressively smaller-micron mesh bags until the purest-possible extracts are obtained. Finally, excess water is drained from the strained mixture and the extracts are left to dry.

 

Olive Oil Extraction

Unlike previously mentioned methods, this technique results in cannabis-infused oil, not pure cannabis extract. It’s a popular option for at-home extraction because it’s safe, simple, and inexpensive. Olive oil extraction, however, produces very low yields of cannabis oil.

 

Essentially, cannabis plants are placed in olive oil (or any other cooking oil) and warmed for 1-2 hours. Next, the infused oil is strained from the plant trimmings.  

Temperature Control During Extraction

 

No matter which extraction method is used, careful temperature is control is an important element of high-quality yield. Extreme temperatures can denature CBD. Additionally, some processes require very specific temperatures; if certain steps are not performed at correct temperatures, the extraction process could fail completely.

CBD Extraction Methods

Cannabidiol (CBD), a cannabinoid found in cannabis plants, is becoming more and more popular as an alternative solution to common ailments. Unlike Tetrahydrocannabinol (THC), another cannabinoid found in cannabis plants, CBD does not have psychoactive effects. When CBD oil is ingested, however, only 20% of it is absorbed. This means that for CBD to be effective, the CBD extraction process must be carried out carefully.

extracted plant oil; CBD is a phytochemical extracted from cannabis plants

There are several options for removing cannabis plant extracts from the plant materials; to be effective, however, each approach must begin with a CBD-rich plant material. Let’s take a quick look at some of the most common CBD extraction methods and the pros and cons of each:

Extraction Methods

CO2 Extraction

CO2 Extraction method for CBD extraction

The CO2 Extraction method uses supercritical carbon dioxide to pull phytochemicals from cannabis plants. Supercritical materials are not quite a liquid but not quite a gas and possess the properties of both. This state is ideal for plant extraction because supercritical CO2 can move through materials like gas and dissolve materials like a liquid.

 

CO2  extraction typically follows these steps:

 

  1. The CO2 is prepared in a compression chamber. First, CO2  gas is turned into a liquid; this is done by dropping the temperature to under -69°F and increasing the pressure to over 75 psi. Next, the the temperature and pressure are both raised until the liquid becomes supercritical.
  2. The supercritical CO2 passes through cannabis trimmings in an extraction chamber where it dissolves and collects extracts from the plants.
  3. The CO2 / extract solution then enters a lower-pressure separator chamber. The lower pressure causes the CO2  and plant extracts to separate. The CO2 returns to the CO2 chamber and the cannabis oil is drained from the separator.

 

CO2  Extraction Pros:

  • Safe when done by professionals- CO2 is used in countless food products and is perfectly safe for consumption
  • Yields high-quality CBD- machines leave very little room for error

CO2  Extraction Cons:

  • Very expensive- setup costs start at approximately $40,000
  • Not for novice chemists- it’s best to leave this method to the professionals

 

Solvent Extraction

Solvent extraction method for CBD extraction

This simple extraction method works by using ethanol as a solvent to remove extracts from cannabis plant trimmings. It usually looks something like this:

 

  1. Ethanol is added to trimmings and mixed for a couple of minutes to allow the ethanol to dissolve extracts from the plant materials.
  2. The ethanol is strained from the trimmings.
  3. The ethanol/extract mixture is slowly heated until all ethanol evaporates and only the plant extracts remain.

 

Solvent  Extraction Pros:

  • Inexpensive- This method doesn’t require any fancy machinery.
  • Simple- This method is pretty straightforward and can even be done at home.

 

Solvent  Extraction Cons:

  • Dangerous- Ethanol is extremely flammable.
  • Could Damage CBD- Ethanol could potentially denature the CBD if overheated or overmixed.

 

Dry Ice/ Ice Water Method

Ice water extraction method for CBD extraction

Ice water extraction creates a powdery resin extract often referred to as “hash” or “bubble hash.” There are several variations to this method, but they all follow these general steps:

 

  1. Finely-chopped plant trimmings are mixed with either ice or dry ice.  This step is supposed to help separate extracts from the plant material.
  2. Water is added to the ice and trimmings and the entire mixture is strained through a mesh bag. (Often, the mixture is strained multiple times through progressively smaller-micron mesh bags until the purest-possible extracts are obtained)
  3. The extracts settle at  the bottom of the strained mixture. The excess water is drained from the top and the extracts are left to dry until they become powdery.

Ice Water Extraction Pros:

  • Inexpensive- Again, no fancy machinery needed!
  • High Yield- If done correctly, this method produces a relatively large amount of plant extract.

Ice Water  Extraction Cons:

  • Not always practical- This method can be labor intensive and time consuming.

 

Olive Oil Extraction

Olive Oil Extraction method for CBD extraction

This technique results in cannabis-infused oil, not pure cannabis extract. It follows these two simple steps:

 

  1. Cannabis plant trimmings are placed in olive oil (or any other cooking oil) and warmed for 1-2 hours.
  2. The infused oil is strained from the plant trimmings.  

Olive Oil Extraction Pros:

  • Easy- This is by far the easiest extraction method and is a popular home option.

 

Olive Oil Extraction Cons:

  • Low Yields- This method produces low yields of heavily diluted CBD.

 

Temperature Control During Extraction

 

Regardless of the method used, careful temperature is control is an important element of high-quality yield in CBD extraction. Extreme temperatures damage CBD. Additionally, many processes need specific temperatures to have success; if ideal temperatures are not maintained, the extraction process could completely flop.

Powerblanket offers the best of the best when it comes to total temperature control. Our products are easy to install and remove and won’t disrupt your current process. Additionally, our products are made to order and can be customized to fit your specific needs.  If you’d like more information, you can give us a call at 888.316.6324.

Spray Foam Insulation: Properties and Benefits

TITLE
3
access_time

Polyurethane spray (spray foam) is an excellent option for building insulation. The r-value for spray foam 3.2-3.8 per inch for open cell polyurethane foam and 5-6.5 for closed cell which means it provides impressive thermal resistance properties. Additionally, polyurethane spraying provides moisture protection and soundproofing properties.

Person using polyurethane spray foam insulation to insulate building structure.

What Is Spray Polyurethane Foam?

Polyurethane spray, or spray polyurethane foam (SPF) is a chemical product comprised of isocyanate and polyol resin; when these two components are combined, the chemical reaction causes the mixture to expand up to 30-60 times its liquid volume.

Polyurethane spraying is often used as an alternative to traditional insulation (i.e. fiberglass insulation) in building and construction. It can be sprayed directly onto roof tiles or concrete slabs, into wall cavities or into holes drilled into walls. Most commonly, it’s used in roofing and wall insulation applications.

R-Value for Spray Foam

Long Term Thermal Resistance (LTTR) of spray foam is measured in r-value. Put simply, r-value demonstrates a material’s ability to resist heat flow. The higher the r-value, the better the thermal resistance. The r-value of spray foam ranges from approximately 3.2 to 6.5 per inch and is heavily dependant on the type of spray foam being used.

(R-Value SVG Image)

The formula to determine the r-value for spray foam

Two Types of SPF

Spray Polyurethane Foam falls into two categories: closed cell and open cell.

Medium-Density Closed-Cell Spray Foam

Medium-Density Closed-Cell Spray Foam (ccSPF) otherwise known as 2 lb foam is dense and rigid. It boasts some pretty impressive properties and benefits. For example, its r-value (thermal resistance) ranges from about 5-6.5 per inch. By comparison, the r-value of traditional fiberglass insulation is about 3-4 per inch. Additionally, when installed at a thickness of at least 2 inches, it becomes a barrier to both air and vapor transfer. This prevents heat transfer via air and mold or mildew issues that can arise from unwanted moisture. Also, closed-cell spray foam rigidity makes it an excellent option or exposed walls or other exposed applications. It’s durable enough to hold up against regular wear and tear without needing repair. The drawback is that ccSPF can be difficult to work with. After the insulation process, it can be difficult to make any changes.

Light-Density Open-Cell Spray Foam

Light-Density Open-Cell Spray Foam (ocSPF), commonly referred to as ½ lb foam, is semi-rigid; while it holds its shape extremely well, it’s sponge-like after installation and can be crushed in your hand. As it expands and dries, it creates small open cells that fill with carbon dioxide. While its r-value isn’t as high as closed-cell foam, it still has great thermal resistance properties with an r-value around 3.2-3.8 per inch. When applied in a thickness of at least 3 inches, it acts as an air barrier. Unlike its closed-cell counterpart, ocSPF cannot become a vapor barrier. While not quite as thermally resistant as closed-cell foam, open-cell spray foam is more sound-dampening. Because it’s less dense and applied more thickly, it effectively absorbs more sound waves.

Benefits

Building frame with some spray foam insulation.

Because spray foam has such great thermal resistance properties, it provides some pretty impressive benefits. The pros of using spray foam insulation over traditional fiberglass insulation include:

 

Save on Energy Costs

According the the US Department of Energy, 40% of home energy loss happens via air infiltration through walls, doorways, and windows. Spray foam creates an air barrier that minimizes this air permeation.

 

Better Insulation

Spray foam insulation insulates up to 50% better than traditional insulation. It blocks conductive, radiant and convective heat transfer; this makes it easier to keep rooms at comfortable temperatures. As mentioned earlier, the r-value (thermal resistance) of spray foam is approximately 3.2-3.8 per inch for open cell foam and 5-6.5 for closed cell.

 

Moisture Protection

Because spray foam can fill in every nook and cranny of the space into which it’s sprayed, it provides excellent moisture protection. Moisture protection prevents expensive issues and damage such as mold, mildew, and rotting wood.

 

Noise Reduction

Polyurethane spray  provides an effective barrier to airborne sound. When used as wall insulation, it hinders sound movement from room to room.

Getting the Most From Your Spray Foam

 

When spray foam materials and equipment get either too hot or too cold, product waste and equipment malfunctions can easily occur. Spray foam cylinder pressure fluctuates with temperature; when the pressure gets too high or dips too low, the cylinder will stop working optimally. Cold conditions can be especially frustrating. Pressure drops as temperatures go down and even though it seems like there is plenty of product remaining, inadequate pressure will render it unusable.  Keeping things at ideal temperatures helps to make polyurethane spray go as far as possible.

Powerblanket spray foam heaters help eliminate temperature and pressure issues with your equipment. They cover the entire spray foam cylinder which maximizes the effectiveness of temperature maintenance.

How Many Gallons of Propane in a 100 Pound Propane Tank?

It probably goes without saying, but a 100 lb propane tank is designed to hold 100 pounds of propane. Because propane is stored and delivered as a liquid, it can be helpful to know what this looks like in terms of gallons.  While there’s a fairly simple answer, there are a few different factors that can affect how many gallons are in a 100 pound propane tank.

The Simple Answer

To put it simply, there are 0.236 gallons per pound of propane (at 60°F).

So, 0.236 gallons x 100 pounds = 23.6 gallons

A 100 lb tanks contains 23.6 gallons

Other Factors

Additional factors don’t add a significant difference to the total volume of 100 pounds of propane, but are interesting to consider.

Water Capacity

Each gas cylinder will have a water capacity number stamped on the collar (it will be something like WC 240). This is the total mass of liquid, stated in pounds, that a cylinder could hold if filled entirely with water.

However, when filled with propane, gas cylinders can only be filled up to 42% of the water capacity (this is to accommodate for the fluctuations in tank pressure as temperatures change)

For this example, 240 (water capacity) x 0.42 (max. capacity)= 100.8 pounds

So our tank can actually hold a maximum of 100.8 lb.

As stated above, we know that each pound of propane is 0.236 gallons.

0.236 gallons x 100.8 pounds = 23.789 gallons

Again, this doesn’t make a huge difference, but is still a factor to consider.

How Temperature Affects Tank Pressure

The examples above assume an ambient temperature of 60°F. At this temp, a “full” tank would produce a reading of about 40% on a tank gauge. When temperatures drop, however, that reading will go down. This is not because there is less usable propane in the tank, the propane has just become more dense or compact and the volume has decreased. The reverse happens as temperatures rise; the tank gauge reading will go up, but it’s still the same weight of propane in the tank– the molecules have just become more spread out.

What Happens When Tanks Get Cold?

While there is still the same usable amount of propane in a cold tank, the lower pressure can cause tanks to stop working properly. Keeping tank pressure up may require more frequent refills; even when there is still “usable” propane in the tank, the volume is not high enough and additional propane must be added to bring tank pressure back up.

Heated propane tank wraps can keep you from having to make time consuming and expensive refills by raising your tank temperature and, consequently, your tank pressure. If you frequently use propane during cold weather months, they’re definitely worth checking out! (Give us a call at 888.316.6324 if you have any questions!)

How Does a Ground Heater Work?

If you participate in projects that require digging or pouring concrete during cold weather, you’ve probably used or considered using  ground heaters. Ground heaters can extend working seasons into the winter and make tasks otherwise complicated by low temps a bit easier. They can be used to thaw frozen ground, cure concrete, and even to warm up surrounding air temperatures. How ground heaters work depends on which type of ground heater you’re using; the most common are hydronic heaters and heated blankets. Hydronic heaters work by heating a propylene glycol mixture and pumping it through long loops of hose that are placed over the area to be heated. Heated blankets work via heating elements that run through the blanket and distribute heat over the surface of the blanket.

Why Use Ground Heaters?

As mentioned earlier, there are a few good reasons to look into using a ground heater.

1. Thaw Frozen Ground

Even with power tools, digging through frozen ground is unnecessarily time consuming and labor intensive (and without power tools, it’s pretty much impossible). Not to mention, most specifications prevent teams from placing concrete on frozen ground. Without ground heaters, that could mean pushing pause on all concrete projects for months at a time! Using a heater will make digging a (relative) breeze and keep operations running all winter long.

2. Cure Concrete

Concrete curing involves a chemical reaction that requires fairly specific temperatures. When temperatures aren’t high enough (above 40-50°F), the necessary chemical reactions will slow down and the concrete can essentially stop curing.

According to the American Concrete Institute (ACI), when concrete is poured at or below 42°F, there must be heat protection for an adequate cure.

Ground heaters can keep concrete at ideal temperatures during the entire curing process and help achieve max cure strength.

How do Ground Heaters Work?

Hydronic Heaters

Prepping ground for cement

Hydronic heaters are portable and can be rented out for projects or bought (a better option if you’ll be using a heater frequently). They use a propylene glycol mixture to heat large areas of ground. Here’s how they work:

  1. A boiler heats the propylene glycol mixture (this mixture effectively conducts heat).
  2. The heated mixture is pumped through a length of hose that is laid in loops over the area to be heated.
  3. A vapor barrier is used to cover the hoses and to keep moisture from escaping.
  4. Typically, Insulated blankets are also laid over the vapor barrier.

Heated Blankets

heated blanket on ground

Heated blankets offer all the portability and convenience of hydronic heaters and then some — they take less time to install and remove and, because they take up less space, are easier to transport.

Instead of long loops of hose and a propylene glycol mix, heated blankets use electric heating elements that run through the blanket and heat the ground surface.

  1. The blanket is spread out over the area to be heated and plugged in.
  2. Electricity powers the heating elements that run through the blanket.
  3. Heated blankets typically include an insulating top layer that traps heat and keeps the blanket working even more efficiently.

Powerblanket provides ground heating blankets including ground thawing blankets and concrete curing blankets. If you’re interested in these heating options, please give us a call at 888.316.6324.  We’d be happy to answer any questions!
