TriggerFoam Pro is a one part polyurethane expanding foam, designed to effectively block the spread of smoke and flame in type V residential construction. TriggerFoam Pro sets into its Final form by using moisture present in the air. When installing the foam, consideration should be given to the 2 to 3X expansion of the foam after it leaves the nozzle. The surface of the foam initially dries within 1 to 5 hr and becomes fully cured in 12 to 15 hr.

TriggerFoam Pro sets well on ordinary surfaces such as concrete, brick, metal and more. Surfaces do not require preparation and can also be damp. After installation, it is recommended that a full 24 hours elapse prior to scraping, sanding, staining or painting. The foam has a R-5 equivalent value when used in place of traditional installation methods.
