Window Draft Proofing
Infiltration of air around and through an old wood window is one of the primary components in heat loss. Our draft proofing system incorporates a
complete weather-stripping package using a variety of silicone bulb, brush felt, vinyl flap and metal interlocking strips. This seals the perimeter and meeting rails of the sash.
In addition, Window Master will remove the old sash balance system (weights and pulleys, tape balances or just friction fit) and replace it with a new hidden balance. This is a block and tackle custom sized unit that is applied to the edge of the sash, allows the window to open and close easily, and stays truly hidden.
This system allows the old wood window to retain the exact same look while operating efficiently. By removing the old weights and pulleys Window Master is able to insulate the weight pocket cavity (another major heat loss area) with dense pack cellulose, fiberglass, or polyurethane foam.
