North Central Insulation: Polyurethane Spray Foam System
What is Polyurethane Spray Foam?
Polyurethane spray foam is produced by a chemical reaction of a polyol and an isocyanate, in the presence of catalysts and other additives. The result is a rigid plastic that expands during the curing process and becomes a seamless layer of closed cell foam.
The"system" includes preparation of the substrate, as well as application of the foam and elastomeric coating. This coating produces a weather resistant surface that can be walked upon for normal maintenance.
The most well-known benefits of spray-on polyurethane foam roofing include compressive strength, lightweight material, waterproofing, and energy efficiency.
