Thermwell R538WH Foam Weatherstrip Tape White 10 Ft

Product Description

The THERMWELL R538WH is a high-density, white foam weatherstrip tape designed to seal gaps and prevent air infiltration around windows, doors, and appliance openings. The tape measures 0.375 inches wide by 0.3125 inches thick and comes in a 10-foot roll. It features a self-stick backing for fast application without additional adhesives. The compressible foam construction allows it to conform to irregular surfaces and fill uneven gaps. HVAC service technicians, appliance installers, and general contractors use this tape for quick air sealing tasks during installation or service calls.

This tape is suited for residential and light commercial applications. Common uses include sealing gaps around window frames and door stops, creating a gasket seal around through-wall or window air conditioner units, and replacing worn refrigerator or freezer door gasket material as a temporary or supplemental seal. It also sees use in automotive and equipment applications to dampen rattles, squeaks, and vibrations on cars and trucks where a compressible foam barrier is needed between panels or components.

Key Features

• High-density foam construction compresses to fill uneven gaps without permanent deformation
• Self-stick backing eliminates the need for separate adhesive during installation
• White finish suits visible interior applications around windows and doors
• Suitable for use as a refrigerator or freezer door gasket seal
• Works as a vibration and rattle dampener on automotive and equipment panels
• 10-foot roll provides sufficient length for most single-door or window sealing tasks

Compatibility

Designed as a general-purpose foam weatherstrip tape for residential windows, doors, window air conditioner units, refrigerator and freezer door perimeters, and automotive or light equipment vibration isolation applications.

Installation Notes

Clean and dry the mounting surface thoroughly before applying the self-stick backing to ensure proper adhesion. For HVAC or appliance sealing tasks, power down the unit before applying tape around electrical or refrigerant-adjacent surfaces. Cut tape to length with scissors or a utility knife. When used around air conditioner sleeves or appliance door perimeters, allow the tape to compress fully under load before checking for gaps.
