TriggerFoam Pro is an expanding polyurethane foam that takes its final shape using moisture in the air.
When installing the foam, consideration must be given to the additional expansion of the foam after it exits the nozzle. The foam surface initially dries in 1-5 hours and becomes fully cured in 12-15 hours.
Low-pressure formula won't warp windows and door frames. TriggerFoam Pro sets well on regular surfaces like concrete, brick, metal, etc. Surfaces do not require preparation and can also be damp.
After installation, it is recommended to allow 24 hours before scraping, sanding, staining or painting.
Foam has a value equivalent to R-5 when used in place of traditional installation methods.
