Bsc Preferred V73/3HDB Shrink Window Kit 3 Pack

Product Description

The BSC PREFERRED V73/3HDB is a shrink window insulation kit designed to reduce heat loss through single-pane windows. The kit includes a crystal-clear plastic film that shrinks tight and wrinkle-free when heat is applied with a standard handheld hair dryer. Installation requires no special tools and works on metal, painted wood, varnished wood, and vinyl-clad window frames using the included double-faced tape. This kit is commonly applied by property managers, maintenance technicians, and HVAC service pros during heating season to improve thermal performance at the window surface.

This product is suited for residential and light commercial applications where single-pane windows are present and adding storm windows is not practical. It is typically installed as a seasonal energy-conservation measure in spaces where draft reduction and improved R-value are the primary goals. The film is clear enough to maintain visibility through the window after installation.

• Increases R-value of single-pane windows by up to 90 percent

Compatibility

Designed for use on standard single-pane windows in residential and light commercial settings where frame surfaces are metal, painted wood, varnished wood, or vinyl-clad.

Installation Notes

Installation does not require licensed trade credentials, but HVAC technicians and building maintenance staff frequently apply these kits as part of seasonal weatherization work. Clean and dry the window frame before applying the double-faced tape to ensure proper adhesion. Apply the film loosely over the frame, then use a handheld hair dryer on a low-to-medium heat setting to shrink the film smooth — avoid holding the dryer too close to any single spot to prevent melting or burn-through. Do not install over windows used as emergency egress without confirming local code compliance.
