Insulation

Although reinsulating an existing building is not usually cost-effective, a major renovation may provide a good opportunity to enhance the insulation. Poorly insulated but accessible roof spaces are one example.

Caulking and weather-stripping joints

Inspect the condition of the weather-stripping in all openings, as it may deteriorate over time. Also check air-tightness between door or window frames and the building, since this is usually where the greatest infiltration of cold air occurs. Caulking can eliminate infiltration.

Window liners

Adding a layer of selective plastic film to your windowpane will significantly block infrared rays from passing through the window and prevent heat from entering or exiting through radiation. Installed on ordinary glass, selective film can nearly double the resistance of single-glazed windows. Liners let you avoid the high cost of changing single-glazed windows to double-glazed windows.

Strip curtains

Made of transparent or rubber strips, strip curtains should be installed wherever there is heavy traffic to and from areas with different temperatures, such as storeroom and garage. Installing strip curtains can decrease climate transfer between the two areas.

Storm windows and storm doors

Storm windows and doors are designed to increase the heat resistance of a window or a door and to decrease infiltration. In many cases, installing them can be more economical than changing the existing windows or doors.

Garage doors

Setting up mechanisms that open and close doors more quickly will minimize transfer time and heat transfer when opening garage doors. If the doors must remain open for unloading, strip curtains or sealing pads can be set up between the vehicle and the building to decrease air transfers.
