You can decrease heat loss through your windows by installing window storms, panels or quilts inside. It is important to make sure all of these fit tightly to the window jambs or trim to prevent warm moist house air from getting behind and contacting the cooler window where it might condense.

“Tyz-All Plastic Interior Storms” and “Advanced Energy Panels” are reusable heavier gauge plastic film panels available through Energy Federation Inc. (www.efi.org) by following This Link.

You can find a detailed instructions and materials list for making reusable homemade double-sided interior wood frame inserts at This Link. Window Improvement Masters is a company in Orford, NH that custom-makes a similar product to fit home owner needs: www.windowimprovementmasters.com. See their ad on back cover.

A company called “Warm Window” and others make multi-layer quilted fabrics for window quilts – google “window quilts”. Unfortunately, many of these quilted fabrics have sewing penetrations through all layers, resulting in potential points of air and moisture leakage.  This may cause condensation problems for you, so incorporating an unbroken barrier into the quilt might be helpful. Quilts should be securely fastened at all edges using one of several optional methods: magnets, sliding track, or hinged clamps.  Custom-made quilts can be ordered from Window Quilt in Brattleboro, VT. www.windowquilt.com

Homeowners can also make rigid window insulation panels from foam board, sealed at the edges with weatherstripping.
