Frequently Asked Questions (FAQ)
What is the difference between Polyurethane and other insulations?
See our product comparison chart - (a new window will open containing a graph)
What is R-Value?
A material’s R-value is the measure of its resistance to heat flow
What is the R-Value of Polyurethane?
When manufactured, the R-value of polyurethane foam is roughly R-9 per inch (2.54 cm). This value decreases until it stabilizes at approximately R-7 per inch
How long does it last?
Polyurthane foam has been shown to last 25 years without internal degradation
How much does it cost?
The cost of spraying polyurethane foam is higher than insulating with some other insulation products, however the cost will actually be 30 % less when considering your energy savings for heating and cooling.. Heating and cooling will drop dramatically, reducing energy bills by as much as 50%.
How do you apply it?
Polyurethane foam insulation is sprayed on as a liquid then reacts and expands in place. This expansion action also seals all of the cracks and crevasses, which means you'll lose less heat.
Does foam off-gas?
All manufactured materials will off-gas to some extent. Medium density spray polyurethane foam meeting the CAN/ULC S705.1 Material Standard is the only building product that is tested for occupant conditions. The industry has then taken an unprecedented stance and required that all manufacturers meet a maximum limit of 1/100 of the government allowable limit. Manufacturers have met this requirement.
