This type of insulation was installed in properties primarily during the late 1970's and early 1980's. It was discovered that UFFI could cause an extreme allergic reaction to the formaldehyde gas which came from this insulation. Although the majority of UFFI has been removed from houses, a prudent buyer should still be aware and concerned about this issue. Check the Seller's Property Disclosure Statement to determine whether UFFI has been disclosed.

Diazolidinyl urea is the primary ingredient in Germall Plus, our chosen preservative. It is derived from plants. It is a formaldehyde donor, but NOT formaldehyde in the gaseous state. Only formaldehyde gas has been linked to breast or other cancers. Diazolidinyl urea is considered safe even at high ambient temperatures, and has been extensively evaluated by the Cosmetic Ingredient Review Board. It is considered safe for both leave-on and rinse-off products.

No, Icynene® Insulation is stable. It does not shrink or sag. The reaction that creates Icynene® Insulation is irreversible and it cannot break down into its' constituent parts. There is a lifetime warranty on the product. A foam that adheres to building materials must remain flexible in order to maintain its' air seal. Building materials expand and contract with changes of season and temperature.

Urea is a synthetic material that draws moisture into the skin helping to hydrate and moisturize. It is also a keratolytic, or exfoliating agent, which helps to loosen dead skin cells and renew the skin's appearance.

Yes. Glass fibres will not stick together unless they are glued or bound together. Formaldehyde has typically been used as one of several ingredients to make this kind of binder - an adhesive that holds fibres together allowing them to keep their shape and overall form. Ordinary fibre glass insulation is made by spraying a phenol-formaldehyde binder on the glass fibres.

In addition to sealing off eave areas to mitigate ice damming in many cases, spray foam insulation (several types are available) is the best choice for insulating new homes and for extensive remodeling projects, because of its air-sealing qualities. The amount of energy lost by convection (air movement through the building envelope) is much greater than what is lost by conduction (heat transfer through a solid). R-value is important, but it measures only heat lost by conduction.

More Information About InsulationTo find more information about foam insulation, there are numerous resources available on the Internet. The first place to start looking for information about foam insulation is agencies and organizations such as the Foam Insulation Association, whose informative Web site outlines the standards within the insulation industry. A great source of information is the National Commercial & Industrial Standards Manual found on the www.insulation.org Web site.

Areas Where Foam Can Be InstalledThere are a few different places in which foam insulation can be installed. Usually foam insulation is placed in various areas throughout a home during its initial building phase. This includes the attic, basement walls, between floors, and as a spray insulate on a roof. Foam insulation is also used within office buildings and businesses.

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.

Why Should Anyone Use Foam Insulation?The American Council For An Energy-Efficient Economy released statistics outlining the amount of money that can be saved by having all building properly insulated. The $13 billion dollars wasted as a result of poor insulation equates to approximately a savings of $200 for each homeowner. If your home is not properly insulated, more energy is needed to keep the home cold when using the air conditioner in the summer, or heating the home in winter.

In March 2002, Johns Manville became the first, and today is still the only, fibre glass insulation manufacturer to stop adding formaldehyde to building insulation as a binder. Instead, Johns Manville uses an acrylic binder that eliminates all binder-related emissions of formaldehyde during manufacturing. The acrylic binder also reduces concerns about formaldehyde in the indoor environment once installed. Quite simply, because it's just a smart thing to do.

Ten years ago formaldehyde was required but it is not today and hasn't been for several years. That's because we've found a better way to make fibre glass building insulation. We asked ourselves some tough questions, conducted research and made some important decisions. As always, Johns Manville places the highest premium on innovation, so we changed the way we do business.

All major manufacturers make some form of formaldehyde-free product, but Johns Manville was and remains the only manufacturer to offer a full line of formaldehyde-free building insulation.

Johns Manville is proud to display the Environmental Choice EcoLogo for thermal insulation materials, reserved only for light-density building insulation made with Formaldehyde-free binders and containing at least 45% recycled content. Combined with 25% recycled content in the US, this translates into 90,000 tons of recycled content that goes into our insulation instead of landfills in North America.

Yes, according to the California Air Resources Board (CARB - a division of the California Environmental Protection Agency), "Formaldehyde emitted from [formaldehyde-containing] insulation materials installed in the ceiling or walls can enter living spaces in the home." [see page 8, http://www.arb.ca.gov/research/indoor/formaldGL08-04.pdf].

Even panels that are UFi Free still emit formaldehyde. This is due to the fact that formaldehyde exists naturally in the wood fiber itself. Formaldehyde exists in all living tissue. Finally, there are other VOCi's beyond formaldehyde that can also be emitted from the product.

We compared an ASTEC-coated metal roof without insulation with another metal roof having 10 cm of polyurethane foam. This allowed us to calculate the surface temperature under identical simulated environmental conditions. In addition, the roofs were given a "typical" 40 m length to determine the thermal shock reduction provided by ASTEC.

All our service technicians carry foam on board their vans so, if a leak in the piping occurs, they can dig out the foam, repair the leak, refill with more foam and tidy any mess they may make in the process. This causes no extra concern or work for the customer (apart from perhaps making the engineer a cup of tea after all that thirsty work!).

Spray Foam Insulation has excellent sound absorption properties and sound transmission properties. For a 2" x 6" wood cavity insulated with Spray Foam Insulation the Noise Reduction Coefficient (NRC) is 75 and the Sound Transmission Coefficient (STC) is 49.

No! Spray Foam Insulation is a clean product. It meets off gassing requirements of CGSB 51.23-92 for new residential construction. No toxic or carcinogenic products were detected. The flame spread classification of Spray Foam Insulation as tested in accordance with CAN/ULC S102 is less than 500 and in accordance with ASTM E-84 is a class 1 (21) at a thickness of 6". The fire testing was conducted from the top of the Steinner tunnel without any product dripping during and after tests.

Yes, Spray Foam Insulation is an ecological product certified by an independent agency: "the Environmental Choice Program (EPC-40) of Environment Canada".
