M-d Building Products 04200 Window Insulation Kit 210x62 in

Product Description

The M-D BUILDING PRODUCTS 04200 is a crystal-clear plastic film window insulation kit designed to reduce heat loss and cold air infiltration through single-pane and drafty windows. The kit installs using double-faced tape and a standard hair dryer, which shrinks the film tight across the frame for a nearly invisible seal. It is sized at 210 inches by 62 inches, providing enough coverage for multiple standard windows from a single roll. The 04200 is suited for residential and light commercial applications where upgrading window glazing is not practical and an immediate reduction in air infiltration is needed. Reported R-value improvement is up to 90 percent over uninsulated glass.

This kit is intended for interior installation on single-hung, double-hung, sliding, and casement windows in residential homes, apartments, and light commercial spaces. It is particularly useful during heating season to stop drafts at older windows without permanent modification. Maintenance technicians, property managers, and knowledgeable DIYers typically install this product as a seasonal energy-conservation measure. No special tools beyond a hair dryer and scissors are required.

Key Features

• Crystal-clear film maintains natural light transmission after installation
• Heat-shrink application with a standard hair dryer produces a taut, wrinkle-free seal
• Installs with included or standard double-faced tape — no fasteners or adhesives required
• Reported R-value increase of up to 90 percent compared to bare windowpane
• Large 210-inch by 62-inch sheet covers multiple windows from a single kit
• Removable at end of season without damage to window frames or trim

Compatibility

Designed for interior use on standard residential and light commercial windows where a temporary, non-permanent insulation barrier is required. Suitable for single-pane and older double-pane windows showing measurable air infiltration.

Installation Notes

Installation is performed from the interior side of the window frame and does not require licensed trade credentials. Clean the window frame surface thoroughly before applying double-faced tape to ensure proper adhesion. Apply the film loosely over the taped frame, then use a hair dryer on a medium heat setting to shrink the film smooth. Avoid direct contact between the heat source and the tape edges to prevent premature adhesive failure.
