Reduce your energy costs by draught proofing your sash windows, and have a more comfortable house as well as lower utility bills. Sounds good – now you have to asses the need, count the cost, and decide which method will fit best with your house, your level of skill, 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.
As the house ages, its windows may lose both their inner and outer seals, the panes may become loose, and the sashes rattle in their frames. They may become hard to raise and lower because of layers of old paint, and may have rotten cords and latches. As people struggle to make the windows work, the frames get looser, the panes lose their putty, and more air leaks in around the window than through it.
Don’t think replacing the windows with modern ones is the only, or the best, option. This is an expensive remedy and one which may destroy the historic integrity of the house. Fixing the existing windows is possible, with either seasonal, temporary means like weatherstripping, or with structural repairs that can leave the windows 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.
Other quick fixes can include an insert, which is just a pane of glass or plastic that fits inside the entire window, creating one more layer of air for insulation, and blocking the movement of air through the loose panes of the outer window. There are plastic sheets, applied to the inside window frame with heat, that seal the window in the same way. Even heavy drapes can block cold air from entering a room through the window.
Real repair involves dismantling the windows and removing all old caulk, putty, and outworn parts like the sash cords and the ‘beads’ that seal the channels and the joins where two pieces of wood meet. Removing the outside and inside trim boards can let you see if the caulking 0between the window frame and the wall needs to be redone. Stiff brush strips can be added to the inner parts of the sashes to let them move easily while still being air tight.
