The DDP SPECIALTY ELECTRONIC MATERIALS 187273 is a 20 oz professional-grade polyurethane gun foam designed for window and door rough opening applications. This low-pressure formulation fills and seals the gap between a window or door frame and its rough opening without exerting enough force to bow or distort the frame. It reaches a tack-free surface state in 8 minutes and remains re-startable for up to 30 days, making it practical for multi-phase installs or job sites where cans sit between uses. The product is UL Classified and is dispensed using a professional foam gun for controlled bead placement.
This foam is used in residential and light commercial construction and retrofit applications wherever windows and doors are set into rough openings. HVAC and weatherization contractors, window installers, and general construction trades use it to air-seal around frames before trim is applied. The low-pressure formulation is specifically suited for applications where over-expansion would cause frame distortion, distinguishing it from general-purpose expanding foams. It is sold in cases of 12 units.
Designed for use with professional foam guns compatible with standard 20 oz polyurethane foam canisters. Intended for window and door rough opening air-sealing applications in new construction and retrofit projects.
Installation is typically performed by window and door installers, weatherization contractors, or HVAC technicians performing building envelope work. A professional foam gun is required to dispense this product. Follow all applicable building and energy codes when air-sealing around window and door openings. Wear appropriate personal protective equipment including gloves and eye protection, as uncured polyurethane foam is difficult to remove from skin and surfaces.
