Temperature and Spray Foam Insulation Guide

Before spray foam insulation (SFI) has been applied and had a chance to cure, it likes to be in a comfortable environment. Think of it as Granny Polyurethane, she needs tender care and just the right environment to be at her best. Everything needs to be just so, and when the setting is right then Granny is happy and more willing to offer protection against the harsh outside world.

SFI has the best adhesion and most ideal curing process when it is applied in 60-80F degrees (15-26C). If the season is right and the ambient temperature is already hovering in that range, then there is nothing to worry about. On the other hand, if installation is occurring in an environment that is below 60F (15C) then heating the space will be necessary. Applying spray foam insulation in cold weather is a tricky business. If the surface is cold but the space underneath the surface is heated (like an attic), there may be condensation. Using SFI in a cold space means the flow will be...Read More >>
