Thermwell VA17WH Vinyl Door Weatherstrip Set 3/4 in X 17 Ft

Product Description

The THERMWELL VA17WH is a 3-piece vinyl door weatherstrip set designed to seal gaps around entry doors and reduce air infiltration. The set includes two 7-foot pieces and one 3-foot piece, totaling 17 linear feet of coverage. Each strip features a durable extruded aluminum backing bonded to a tubular vinyl seal. The aluminum spine provides structural rigidity and secure fastening to the door stop or frame, while the tubular vinyl compresses against the door face to form a consistent weathertight seal. This type of product is typically installed by carpenters, handymen, or HVAC service techs addressing building envelope air leakage.

The VA17WH is suited for residential and light commercial exterior door applications. The white finish blends with standard painted door frames. The three-piece configuration allows the installer to address the top rail and both vertical sides of a standard door opening without cutting a single continuous strip. The aluminum-plus-vinyl construction holds up to repeated door cycles and resists deformation from temperature swings common in exterior applications.

Installation Notes

Installation is typically performed by a carpenter, general contractor, or HVAC technician addressing building envelope sealing. The aluminum backing is fastened to the door stop with nails or screws; no special tools are required beyond a hammer or drill and a hacksaw or tin snips for trimming. Ensure the door is properly aligned and closes squarely before installing the weatherstrip to achieve even compression of the tubular vinyl seal. Follow applicable building code requirements for exterior door sealing in your jurisdiction.
