Spray foam, done properly.

Insulation performance lives and dies by application. R-value only matters if the product is installed to depth, edge to edge, with no shortcuts, and Wallis never skimps on material, because an insulation barrier is only as good as the way it goes on. Every job receives a proper, full-depth application that creates a continuous thermal break, holding heat out in summer and in through winter.

Our minimum application is always more than adequate for a proper R-value, so thickness and performance are never in question, and what we promise as a minimum is exactly what you receive, every time, matched to what your home or building actually needs. We have been applying urethane products this way since 1997, and that experience shows in every job, whether it is a single room or an entire commercial build. When the application is done right, the barrier does its job for the life of the structure, and that is the standard Wallis holds on every project.
