Our small enlargement foam is built especially for window and door installations. It expands to fill voids that fibreglass batt insulation might not successfully achieve. As opposed to fibreglass, foam functions a vapour barrier that seals openings/gaps and lower leakage. Stuffed into gaps, compressed fibreglass insulation loses its insulating worth. https://jonathanc958jxm2.boyblogguide.com/profile
