Creating a durable, airtight seal around windows and doors requires precision. Sprayman’s Window & Door Foam collection is engineered for controlled expansion, making it ideal for sealing gaps without stressing frames or hardware.

These low expansion spray foam products work as reliable window insulation foam and door foam, helping prevent drafts, improve energy efficiency, and maintain structural stability. Designed for professional installers and experienced DIY users, Sprayman’s gun-grade expanding foam sealants deliver clean application and consistent results.

Why Use Low Expansion Foam for Windows & Doors?

Standard expanding foams can apply excessive pressure during curing, which may cause window warping or door jamb misalignment. Low expanding foam for windows and doors is formulated to expand evenly and safely.

• Safe for Frames: Compatible with vinyl, aluminum, and wood
• Airtight Seal: Reduces air leakage and drafts
• Controlled Expansion: Prevents pressure on window tracks and door jambs
• Installation Ready: Ideal for rough openings and frame gaps

Unlike general-purpose spray foam, window and door spray foam is designed specifically for precision sealing.

Professional Gun-Grade Application

All products in this category are gun-applied, allowing better flow control, higher yield, and cleaner bead placement than straw-applied foams. Gun-grade expanding foam sealant is the preferred choice for professional window and door installations where accuracy and efficiency matter.
