Our low growth foam is designed especially for window and door installations. It expands to fill voids that fibreglass batt insulation may not properly achieve.

Stuffed into gaps, compressed fibreglass insulation loses its insulating value. https://paxtonxcegf.blogsvirals.com/31450076/not-known-details-about-home-front-doors-in-scarborough-ontario
