subject: Methods To Reduce Your Energy Costs By Draught Proofing Your Sash Windows [print this page] You can reduce your energy costs by draught proofing your sash windows, and you will make your home more comfortable at the same time. If your windows are letting your heat out and cold air in, you need to decide which remedy will fix the problem in a manner suited to your home and your budget.
Sash windows move up and down in a frame, and are usually made of wood, though they may be metal or even hard plastic. This type of window is typical of older homes and houses built in traditional styles. The windows have two sections, one or both moving up and down to admit the outside air, or shut it out. They are attractive and pleasant to live with, until they lose their sealing power.
The problem arises when these windows become older, loose in their settings, worn by the friction of opening and closing, or stiffened by age and old paint. The caulking around the outer frame can lose its seal or fall out, the inner seals of the window casings may become worn, and the putty around individual panes of glass can fail. Once any seal allows air to seep through, the insulating value of the window is compromised.
Replacing the windows in a house is an expensive proposition, and new windows may not match the period of an older house. For either reasons, you may want to fix your existing windows. Your options will be to effect temporary blocking systems, such as weatherstripping, or to repair the windows and the fabric of the house so the whole is as good as new.
Weatherstripping refers to the practice of blocking air flow around the parts of a window with strips of material. These strips can be felt, putty cord, foam, or even metal. The weatherproofing material simply blocks the gap between the window and its frame, or the frame and the wall, and the space where the two parts of the window meet. Weatherstripping can be applied in a manner that is almost invisible, but many do it yourself homeowners just ignore the look during the winter months in order to save energy.
Weatherstripping can be hidden from view if the trim is removed from around the window, but this is beyond many homeowners, who sacrifice appearance for heat retention during the winter months. There are also kits that contain air tight plastic sheets, that homeowners can tape to the inside of windows and then shrink to fit, using a hair dryer or other heat source. Even heavy curtains can block draughts in a similar mechanical manner.
Another way is to dismantle the window, put new caulk around the outside and each individual pane, and then replace the inner seals of the window frames with new beads or, ideally, reinforce them with stiff brush strips that block the passage of air while still allowing the sashes to be raised and lowered. These extensive repairs will retain the architectural integrity of the house and make it energy efficient for years to come.
Reduce your energy costs by draught proofing your sash windows, a common sense solution which can be done yourself or by a professional draught proofing specialist.
