Structural Effect
Spray in Insulation – it strengthens a building structure
In all structures, walls are the main structural component of a building. In wood frame construction, the weight of the roof, shingles, standing rain water and snow add weight and exert downward forces on the walls resulting in compressive forces. In addition, Strong winds and gusts impose lateral forces onto your home’s walls. These forces add a “shearing” force to the walls. Closed cell insulation and spray on insulation can help.
Local building codes provide guidelines on how structures need to be designed to withstand these forces and loads. These guidelines are minimum standards. With a high density Closed Cell Spray in Foam Insulation, as it fully adheres to the stud walls and the exterior sheathing, it reinforces both and makes the wall rigid. With this added rigidity, the wall movement due to wind, vibration, and occupant activity is greatly diminished. Additionally the walls have greater than code required resistance to "racking events" such as hurricanes or other strong wind situations. 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.
The graph below illustrates a stud wall filled with spray on foam insulation adds significant strength to building walls. For each load applied, the foam insulation filled walls racked less and offered greater resilience.
