Heavy-duty gaps require heavy-duty seals. Froth-Pak™ Spray Foam Sealant is a two-component, quick-cure polyurethane foam that fills penetrations and cracks with significantly reduced curing time.
This heavy-duty, two-component foam seals out moisture, dust, allergens, and pests while improving energy efficiency, and our newly reformulated product delivers a GWP reduction of over 99%. Our new Froth-Pak™ Spray Foam Sealant contains no ozone-depleting chemicals or HFCs while elevating the performance attributes you have come to expect.
Froth-Pak™ Spray Foam Sealant is a two-component, quick-cure polyurethane foam that fills penetrations and cracks in rim joists, roof wall junctures and around pipes and ducts greater than 2" and less than 4" wide. Froth-Pak™ Sealant is a chemically cured foam designed to significantly reduce curing time. It dispenses, expands and becomes tack-free in seconds, saving pros time on the jobsite.
