To stop cold air from coming through your windows, Edgetech recommends using their TruFit Window Insulation Tape. This is a pre-compressed foam insulation tape that provides a thermal barrier between the window or door frame and the reveal. It ensures true energy rating performance and a long-life weathertight seal. TruFit expands to effectively seal all gaps and spaces, providing consistent weather protection, air tightness, and eliminating draughts. The tape retains up to 23% more heat compared to traditional installation methods, helping keep warm air in and cold air out.
