PURFECTSEAL is a single-component, moisture-curing, low-expansion gun foam, which has good cold weather gun ability. It is specially formulated to be ‘O‐Zone’ friendly and is extremely economical — ideal for weather applications down to ‐10°C.

PurfectSeal gun foam is a professional-grade expanding polyurethane foam dispensed through a foam gun for precise, controlled application on gaps, penetrations, window frames, door perimeters, and utility entries. At The Contractors Site, we supply gun foam to Ontario contractors and building envelope specialists who need accurate, consistent foam application without waste.

Precision Foam for Air Sealing Applications

Gun foam is particularly effective for air sealing rough openings, utility penetrations, and perimeter gaps around windows and doors — the air leakage pathways that drive heat loss in Ontario buildings. Controlled foam application fills the gap completely without over-filling or pushing into finished spaces, which is the result that professionals expect and homeowners and building inspectors measure.

Features:

  • O-zone friendly
  • Low-expansion
  • Economically priced

Bonds to:

  • Most construction substrates
  • Wood
  • Metal
  • Brick & mortar
  • Concrete
  • Stone
  • Most plastics

Basic uses:

  • General sealing around windows and doors
  • General construction applications
  • Gap filling in new & retrofit construction

Expanding Formula for Complete Gap Fill

Polyurethane gun foam expands after application to fill the full depth of the gap or cavity being sealed. The expansion rate is formulated for professional use — enough to fill the cavity without generating the excessive pressure that can bow window frames or shift door jambs during cure. Controlled expansion is the difference between a professional foam application and a remediation job.
