Penta spray foam applicators are certifed to apply foam and what's more they're very experienced . We shot this video for you so you can see a large residential property being sprayed with 2lb spray foam . 2lb foam when expertly applied sticks permanently to the structure and will never warp or shrink . What's even better is that while it's an amazing insulator , it also is a tested and approved vapour barrier which stops condensation - call our foam an 'anti condensation spray' if you will.
