Adding structural strength with spray foam insulation Not only is spray foam insulation an effective insulation product for keeping homes warm and dry, it also increases wall strength.
When architects, builders and homeowners are thinking about structural strength for their next build project, they’re definitely not thinking about how their insulation product might come into play.
Due to its acoustic performance, it’s also a great solution for medium density housing, helping to reduce transfer of noise between building storeys and adjoining wall spaces.
Most people know about spray foam’s superior performance for preventing heat loss, but don’t consider the fact that due to spray foam’s rigidity, it can also provide additional strengthening to walls.

What is Spray Foam? Spray Foam insulation is rigid, lightweight, flexible, wind resistant, and effective in extreme temperatures and weather conditions. When applied, spray foam adheres immediately and expands from 20 to 120 times of its liquid volume. Spray foam insulation offers consistent insulation performance (R-value) and other advantages over alternative insulation systems due to its ability to provide an integral air barrier, and in the case of close-cell spray foam; water vapour resistance. Spray foam also offers great acoustic performance. Spray foam can be applied to interior and exterior wall masonry, ceilings, underfloor and roofing, making it a holistic approach for tackling two birds with one stone: temperature and moisture control, and structural support.
