About Polyurethane FoamPolyurethane foam is a material that was engineered during World War II by Professor Dr. Otto Bayer to replace more expensive natural resources like rubber. Rapidly expanding beyond the war uses it was initially designed for, polyurethane foam today is one of the more wildly used materials around. The diversity of uses is also impressive ? polyurethane foam can be found in everything from medical research labs to the cushions in your couch or chair.

YES. Polyurethane foam has been used on many different applications for many years, and has been tested extensively for safety. There are no emissions or any harmful substances related to the foam under normal conditions.

NO. INSTA-PANELS® are made of polyurethane foam, which can by classified as self-extinguishing material. Steel covers on Insta–Panels ® additionally protect foam against flame spreading. For example, exterior doors in most houses contain polyurethane foam are considered safe and do not require additional protection.

Polyurethane Foam MattressThe advantages of a polyurethane foam mattress have been quick to take hold among people who are looking for high quality comfort constructed from affordable materials. Where premium foams like latex and memory foam can be prohibitive for environments like boats, RV and storable guest spaces, polyurethane foam is an intelligent option.

Flexible polyurethane foam (FPF) is modified type of polyurethane foam that is used in areas where strength is needed. It has the unique ability to absorb shock when it is used in automobiles or shipping supplies. Other than its ability to absorb shock, flexible polyurethane is able to bear a load. It is a type of foam often used in construction and furniture manufacturing.

Quite simply, it is "insulation plus sealant". As a rigid cellular plastic with over 95% closed cell content, Spray Polyurethane Foam Insulation acts as insulation, an air barrier and, in some cases, also a vapour barrier. Spray Polyurethane Foam Insulation will cut energy costs and improve comfort levels in any building.

Untreated this foam can give off very nasty toxic fumes when it burns. The heat from a fire in furniture containing the foam reaches such a level that people cannot pass through it within about three minutes of the fire starting.

Provides Total Body SupportA polyurethane foam mattress has increased in popularity over the past few years because of its ability to provide total body support during sleep. Upon initially resting on the polyurethane frame mattress, the components of the mattress are designed to surround your body and conform to its shape. This is in contrast to regular coil mattresses, which make the body's shape conform to it.

Polyurethane foam insulation is sprayed on as a liquid which reacts and expands in place. This expansion action also seals all of the cracks and crevasses in your wall's exterior sheathing. The result is that air can no longer slip in - your house will be less drafty and more comfortable. Air leakage can also introduce moisture into the wall cavity, resulting in wet insulation and mold and mildew. With the sealing effects of polyurethane foam insulation, this will not be a concern.

Yes. Building codes provide for the use of spray polyurethane foam in the Foam Plastic section. This section of the code also describes the use of thermal barriers.

Yes! The installed cost of spray polyurethane foam is somewhat higher than glass fiber batts or blown-in cellulose. However, the higher initial cost is partially offset because you can leave off the house wrap and your heating and air conditioning equipment can be smaller. You will save in your heating fuel and electric bills. Studies suggest that homes insulated with spray polyurethane foam use 20 to 40 % less energy than homes insulated with conventional insulation.

Not that we're aware of. We've looked at 20-year old spray foam projects and we have not observed any signs of deterioration. We expect the polyurethane foam system to insulate and seal your home for the life of the house.

It's not very practical due to the expense of the equipment involved. Spray foam application requires complex equipment and a skilled installer. Dwyer's has the experience necessary to do the job for you right!

Yes! Two pound foams are rigid and structural. Your walls will be more resistant to winds and you'll notice less creaking and shaking when doors are slammed or when the kids are romping about.

Neither foam is necessarily better than the other; rather, each foam type has unique properties and may offer advantages in certain instances. The primary difference between the two is the density of the foam. EPS foam density is a nominal 1 pound per cubic foot, while Polyurethane foam density is nominally 2.2 pounds per cubic foot.

Polyurethane is a term used to describe a wide ranging family of elastomers (any compound exhibiting the characteristics of natural rubber; stretchy and elastic.). Poly meaning "many" and "urethane" the classification of the chemical structure. Polyurethane or urethane for short, is used as a solid cast material (bushings). Polyurethane can be as soft as a rubber band or as hard as plastic.

Low density polyurethane foamThere are three primary categories for polyurethane foam, with the lowest level labeled as low density polyurethane foam. Low density foam refers to the concentration of polyurethane within the material, and lower concentrations create a lower density. This type of foam is typically recommended for items that experience infrequent use, such as an outdoor cushion, an infrequently used custom mattress, and certain types of furniture cushion.

Medium density polyurethane foamMedium density polyurethane foam is a medium quality foam that is best used in moderately priced furniture including sofas, chairs and certain types of outdoor furniture. It can also be used as the base in certain types of custom mattresses, or as a base to provide support for higher quality foams like memory foam and latex foam. Medium density foam tends to fall between the high 1.8 pound range to just under a 3lb range.

The technical requirements for medium density spray polyurethane foam is outlined in the CAN/ULC S705.1 Material Standard. The physical properties are: Initial Thermal Resistance - 50mm sample after a minimum of 2 d and a maximum of 14 d at 23 ±2°C Note 1: The test methods used to determine the material properties provide a means of comparing different cellular plastic thermal insulations. They are intended for use in specifications, product evaluations and quality control.

It acts as a seamless insulation making it more efficient than any other material used in the industry Because SPF is light and versatile and has strong adhesive properties, it easily fills difficult to reach places and adheres to most clean surfaces
