Polyurethane Foam Strengthens Your Home Sep 08, 2017

Building codes require that your home’s walls be designed to withstand these various forces and loads. However, when walls are built to just the minimum standards, while still safe, symptoms of movement such as creaking and shaking during high winds or occupant usage often occurs.

Higher density, closed cell spray foam insulation inside your stud walls fully adheres to both the exterior sheathing and the studs, reinforcing both. With this added rigidity, there will be less wall movement due to wind, vibration, and occupant activity. Additionally your walls have greater than code required resistance to “racking events” such as hurricanes or other strong wind situations.

SPF also can add structural strength to buildings. NAHB Research demonstrated SPF filled walls could add from 75% to 200% racking strength to walls of OSB, plywood, light gauge metal, vinyl siding or gypsum board.
