Touch/N Foam professional 2-component spray foam kits provide quick and simple solutions to air sealing projects in residential and commercial buildings. Simply "point, spray and watch" as the foam expands to create an air-tight seal that will not shrink, compress, settle or biodegrade. Foam expansion acts in less 60 seconds and helps you save up to 28% on your energy bill. This closed-cell foam is designed to resist moisture penetration, protecting against mould and mildew. Easy to use, the pro system 600 kit is great for larger projects where higher yield provides greater economy, yielding up to 600 board feet of coverage.
