What to Look For in a Double Glazing Sealed Unit Replacement Double glazing, or sealed units as they are also known, can fail in time. This normally manifests as a unsettling draught inside the home.

Measure Over time, double glazing units (also called sealed units) will begin to fail, normally it's in the form of a draught or losing their air-tight seal. This is because over time, the gas (normally inert Argon) in the panes can leak out because of shrinkage of the sealing material. The loss of seal can be caused by environmental factors such as exposure to direct sunlight or by the use of chemical cleaners that may harm the glass and erode the seal. When a seal fails, it could cause a discomfort in a house and it is not unusual to notice an improvement in the energy efficiency of a house as a result. It is important to perform a visual inspection of your double-glazing regularly. In addition to checking visually for signs of damage the most important indication is a feeling of a draught in a room. This is the initial sign of the need for a new double-glazed unit, since it is difficult to fix the problem after it has been established. When replacing a double-glazed sealed unit, it is vital to measure the proper size of the window you are replacing. This is due to the UPVC frames they sit in are not tolerant of movement. If a new unit is too large, it will not fit. To do this accurately it is essential to prise out the beads and take a careful measurement. This will ensure that the newly sealed unit has the correct size. You can purchase replacement UPVC frames beads on the internet.

Begin by opening any casement or vent windows in the frame to get access to the edge of the existing glass unit. Then, you can place your calipers around the frame, clipping them against the existing unit on each side to measure the thickness. This will provide you with the exact dimensions of the newly sealed unit. Next, carefully cut through the adhesive strip that keeps the glass in place with an ordinary knife. Once the adhesive strip has been removed, use a putty or shovel to gently pry the frame away from the glass. Be aware that glass is brittle and may break if you put pressure on it. Be careful not to scratch or damage the frame or the sealant. Clean and prepare the frame for the double-glazed sealed unit. If you are installing an enclosed unit, make sure you use a silicone caulk which can be able to withstand the harsh Australian weather.

This can cause the window to become fogged and can also lead to the formation of stained areas between the panes. The only way to get rid of the condensation is to replace the window. Once the old unit is removed, the frame is cleaned and prepped for a new sealed double glazed unit replacement. Based on the style of the window, it may require to be primed or painted prior to the sealant is applied. It is important to allow any varnish or paint to completely dry prior to applying the new sealant. The existing window will need to have the beads removed before the new unit can be installed.

This will help ensure a strong bond when the pane is sealed in the future. Once the glass is cleaned and washed, clean it both sides to eliminate any remnants. Fit Double glazing units that are sealed for replacement can be a cost-effective solution to increase the comfort of your home or cut down on the energy bills. Modern replacement units are more energy efficient than earlier models and can be put in on the existing frame. They can also offer security benefits, since they can include laminated and toughened safety glasses. The key to a proper fitting is precise measurements. A UPVC window frame has limited tolerance, and if you order an upgraded double-glazed window that's just a few millimeters too big it won't seal properly. Take measurements of the width and height to avoid this problem. The seal of a double-glazed unit may fail due to a variety of reasons however, condensation between the two glass panes is one of the most common. This can cause a draught or calcium deposits to form on the glass. This is usually a sign of a problem with the gas filler in the sealed unit or that moisture has made its way into the frame.

The spacer bars are typically filled with desiccants which adsorb any moisture that might form between the glass panes. When the windows are made or over the life of your windows, the seal may degrade in the most common way. This is caused by environmental factors like direct sunlight, which can speed up the shrinking of the seal or the use of strong cleaning chemicals which will cause damage to the seal.
