polyurethane spray,protective coatings
I have applied polyurethane foam for insulation my home.. There are two types of spray foam insulation: open cell and closed cell. Closed cell insulation typically has a higher R-value, so you get more bang for your buck. Spray foam insulation is expensive and durable. The product is more expensive inch for inch, and requires installation by a professional. It's sprayed in your walls as a liquid, then expands and hardens. Spray foam insulation is great because it fills every little nook and cranny creating an air tight seal. It doesn't biode grade, so once installed it will be there for the life of your home. It also doesn't shrink or settle. Spray foam is a great option if you're sealing small spaces like outlets, around window frames, and doorways. Choose best spray foam-e.gultimate linings, qwikliner , xtreme liners etc.
