What to Look For in a Double Glazing Sealed Unit Replacement Double glazing, or sealed units, as they are commonly referred to, can fail in time. This normally manifests as a unsettling draught inside the home. Lifting the new unit into position is a task that requires precision and care. Its fit reflects the measure of your efforts and is an assurance that it will improve the comfort and efficiency of your home. Measure Over time, double glazing units (also called sealed units) will start to fail, typically it's in the form of a draught or by losing their air-tight seal. This is because over time, the gas (normally inert Argon) in the panes could leak out due to shrinkage of sealing material. The loss of seal can be caused by environmental factors such as exposure to direct sunlight or the use of chemical cleaners that can harm the glass and weaken the seal. It is not unusual to notice an energy efficiency difference when a seal fails. It is essential to conduct a visual inspection of your double-glazing regularly. Another important sign as well as checking for visible signs of damage, is a feeling of a draft within the room. This is the initial sign of the need for a replacement double-glazed unit as it is not easy to fix the issue once it has been established. In order to replace a double-glazed sealed unit, it is vital to correctly measure the size of the existing window. The UPVC frames that they sit in are extremely stiff and if a window is too large it will not fit. In order to do this accurately, it is important to take the beads out and measure them carefully. This will ensure that the sealed unit is built to the correct dimensions.

This will also give you the chance to examine the condition of the window frame making sure that it is sturdy enough to support the weight of the new glass. Begin by opening any casement windows or vents within the frame so that you can see the edges of the unit. Set your calipers in the frame and then clip them against the existing unit to gauge its thickness. This will tell you the size of the new sealed unit and allow you to place an order according to the exact measurements. Then, carefully cut the adhesive strip that keeps the glass in place using the knife of a utility. After the adhesive strip has been removed, use a putty or shovel to gently pull the frame away from the glass. Be aware that glass is fragile and can break when you push it. Be careful not to scratch or damage the frame or the sealant. Then, clean and prepare the frame to be sealed with double-glazed.

Based on the design of the window, it may be required to prime or paint the window prior to applying the sealant. It's important that any paint or varnish is allowed to completely dry before the sealant is applied. The window in question will require the beads removed prior to the new unit can be installed. This can be done with the help of a screwdriver or a sharp chisel. Position the blade of your tool on the very edge of the bead, and gently lift it off of the window frame. To avoid damaging the window frame, make a series of small cuts instead of one deep cut. Once you have removed your bead frame, gently lift it off the remaining glass and place it in a safe place to be stored. Remove any remaining sealant from the bottom surface of your glass using the knife or a utility tool. This will ensure a good seal when the glass is re-sealed. Once the glass is clean thoroughly wash both sides of it to get rid of any traces or smears.

Modern replacement units are more efficient than previous models and can be fitted to your existing frame. They also offer security advantages since they can incorporate toughened safety glass as well as laminated glass. The key to a good fit is accurate measurements. A UPVC frame has a very small tolerance. If you choose a double-glazed unit that is a couple of millimeters more than the original one, 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 for many reasons however, condensation between the two glass panes is the most frequent. This can result in a visible calcium deposit on the glass. This is typically a sign of a problem with the gas filler inside the sealed unit, or that moisture has gotten into the frame.

The spacer bars contain desiccants that absorb moisture between the glass panes. When the windows are made or over the lifespan of your windows, the seal material may deteriorate, this is often caused by environmental factors like direct sunlight, which can speed up the shrinking of the seal or strong chemical cleaning products that could cause damage to the seal.

Make sure to use an adhesive made of silicone that is suitable for Australia's climate and is able to withstand thermal expansion and contraction. Once the silicone has been applied to a side edge, run your smoothing tool across it to press and squeeze the silicone onto the glass surfaces. it will eliminate any air bubbles, then fill gaps and make sure the seal is secure.
