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 2-3 times expansion of the foam after it leaves the nozzle. The surface of the foam initially dries within 1-5 hours and becomes fully cured in 12-15 hours. TriggerFoam Pro sets well on ordinary surfaces such as concrete, brick, metal, etc. 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. TriggerFoam Pro is dispensed through a special gun that allows the user to control the rate of flow as well as the size of the bead for more precise placement of the product, allowing it to be used in a wide variety of applications. Use it to fill, seal or insulate. It blocks drafts, stops leaks, saves energy, adheres to all types of construction materials, deadens sound, acts as a buoyancy material once cured, controls radon, helps confine asbestos fibers, and can be used in HVAC applications.
