Replacing Double Glazed Units Double-glazed units can be replaced to lessen heat loss and noise, and also reduce heating costs.

This is a delicate process that requires patience and caution. Take your time and wear safety equipment to prevent slips and shards.

Preparing the Frame Whether you are replacing a fixed or fixed window or a sliding door with an opening or fixed sash, be sure that the new unit is the correct size. UPVC frames allow only a small amount of movement and a sealed double glazing unit that is even a few millimeters too large is likely to not fit. To ensure accurate measurements, measure carefully and seek the advice of an expert. Once you have a clear understanding of the dimensions of your replacement and you are sure it is correctly fitted remove the glass from its frame. Be sure to work in a well-lit location, and wear safety equipment, such as gloves, to avoid injuries from glass shards. Make use of a putty blade to pry off the glaze stripes or beads that hold the glass to the frame, and remove them from the perimeter of the pane. You should avoid slipping the glass or straining the frame. Verify that the frame will open and close easily when the double-glazing unit that is sealed is installed. You can alter the fit as needed by adding or removing packing. If the frame is for sliding glass doors, you might need to add packers to the top of the hinge as well as the opposite corner to avoid the sash from catching when it opens. Finally, clean the frame and remove any old sealant or glazing tape, as needed. Assess any damage, and make minor repairs if necessary using wood filler or sanding. The frame will be rejuvenated with a final cleaning and inspection so that it can withstand Australia's harsh weather for a long time. Lifting the New Unit Over time, double-glazed units can experience problems such as condensation between the panes or misting. This can reduce the efficiency of your windows which allows cold air to get in and warm air from your heater to escape, leading to uncomfortable energy bills and discomfort.

Desiccants also absorb moisture from the air, which prevents condensation and mould in the frame. The spacer bar is made of aluminum and is an essential component of the insulation system. The aluminium not only prevents heat transfer, but also keeps the edges warm of the window insulated to prevent condensation.
