Spray Foam Insulation
Spray foam is a petroleum based toxic chemical concoction that squirts out of a nozzle and expands to fill in gaps and voids. It makes walls airtight which can be a problem unless there are other systems in place to keep moisture from causing problems like mold and wood rot. The airtightness also keeps any outside air from entering the home which can lead to higher energy bills and poor indoor air quality.
Why is spray foam so expensive?
Spray Foam is used to insulate homes and commercial buildings to save on energy costs. It does this by reducing air infiltration which accounts for 40% of a building’s energy loss. Spray foam is also an effective sound insulator and can help prevent condensation between the wood studs and drywall in walls. More info : www.armorinsulations.com
There are different types of spray foam insulation such as open-cell or closed-cell. Open-cell spray foam is less dense and allows moisture to pass through, but it still provides good insulating value. Closed-cell spray foam sets into a rigid solid and is much better at insulating because it contains bubbles of gas that slow down heat transfer.
Both open-cell and closed-cell spray foam contain the same ingredients (isocyanate and polyol resin), but some manufacturers use ‘greener’ versions that reduce the amount of petroleum-based chemicals in their formulas. Look for a label that says ‘low-GWP’ (global warming potential) or try to find a product that uses HFOs as blowing agents rather than traditional HCFCs. BASF Walltite CM01 and Genyk Boreal Nature are two examples of low-GWP spray foams that use HFOs.
