Standard perimeter gasketing creates a continuous weatherproof seal around door frames in commercial and institutional buildings. The Pemko 303AV3684 installs on door frames to prevent air infiltration, water penetration, and energy loss through gaps between the door and frame. This 36" x 84" gasket assembly addresses building envelope requirements and energy code compliance.
The 303 Series features an anodized aluminum retainer with vinyl insert that compresses against the door surface when closed. Mill finish aluminum provides corrosion resistance while maintaining clean architectural lines. The continuous seal reduces HVAC load and improves interior comfort by blocking drafts and moisture intrusion.
