What to Look For in a Double Glazing Sealed Unit Replacement

Double glazing, also known as sealed units, as they are commonly referred to, can fail in time. This is usually evident as a draft within the home.

Lifting and placing the new unit is a delicate procedure that requires precision and care. Installing the unit is a reflection of your preparation and will ensure your peace and comfort at 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 by 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 deterioration of the seal could also be caused by environmental factors such as exposure to direct sunlight, or making use of powerful chemical cleaning products that may harm the glass and erode the seal.

If a seal is damaged, it can cause an uncomfortable feeling within a home. It is not uncommon to notice a difference in the energy efficiency of a property due to the failure of a seal. This is why it is a good idea to perform a routine visual check of your double-glazed.

In addition to visually checking for signs of damage, the primary indication is a feeling of a draught in a room. This is typically the first sign that a new double glazed unit is needed as it can be very difficult to correct the issue after it has been established.

When replacing a double-glazed sealed unit, it is vital to accurately measure the size of the existing window. The UPVC frames they are placed in are extremely rigid and if the unit is too big, it won't fit. To do this accurately, it is important to remove the beads and measure them carefully. This will ensure that the new sealed unit is built according to the right size. You can buy replacement sealed double glazed units upvc door seal repairs frames beads on the internet.

It is important to remove the old glass prior to begin work. This will ensure that the new pane will fit properly. You may also check the frame to make sure it is sturdy enough to support the new pane.

Start by opening any casement windows or vents in 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 measure thickness. This will tell you the dimensions of the new sealed unit and enable you to place an order in accordance with the measurements.

Utilize a utility blade to cut precisely the strip of adhesive that holds the window in place. Once you've removed the strip then gently lift the glass off the frame using a putty knife or shovel. Be aware that glass is fragile and can break if you push it. Be careful not to scratch or damage the frame or sealant.

Then, clean and prepare the frame for the double-glazed sealed unit. If you're installing a new sealed unit, select the right silicone caulk that will stand up to Australia's extreme weather conditions without becoming brittle or flaky. A quality silicone sealant is also watertight, protecting your property from water infiltration and resulting in a stronger, more durable finish.

Clean

Over time the inside of double-glazed windows may appear cloudy or even opaque. This is a sign that the seals are failing and it's an indication that the window needs replacing.

Based on the style of the window it may require to be primed or painted prior to the sealant is applied.

If the window that was in use was secured with beads then these will need to be removed before a new window can be fitted. This can be done using a sharp screwdriver or chisel. Place the blade of your tool against the edge of the bead and gently prise it away from the window frame. Do this using several shallow cuts rather than one deep cut to avoid damaging. After you have removed the bead frame, carefully lift it off the remaining glass and set it aside.

Using your knife or a tool, cut off any remaining sealant from the bottom surface of the glass. This will ensure a good seal when the glass is re-sealed. When the glass is clean thoroughly clean both sides of it to remove any residues or smears.

Fit

Whether you're looking to reduce energy costs or increase the comfort of your home, replacement double-glazing sealed units are a low-cost and durable solution. Modern replacement units are more efficient than earlier models and can be affixed to your existing frame. They also offer security benefits because they can include toughened safety glass and laminated glass.

The most important factor to ensure a perfect fitting is precise measurements. A UPVC window frame has little tolerance, and if you order an upgraded double-glazed window that is just a few millimeters larger than the original, it won't be able to seal properly. Take measurements of the width and height to avoid this issue.

The seal of a double-glazed unit could fail for many reasons but condensation between the two glass panes is the most frequent. This can lead to draught or unsightly calcium deposits on the glass. This is typically a sign of an issue with the gas filler within the sealed unit, or that moisture has gotten into the frame.

Double-glazed units are made up of two or more glass panels that are separated by the spacer. The spacer bars are stocked with desiccants which absorb moisture that may be present between the glass panes. The seal material can deteriorate during the manufacturing process or over the lifespan of your windows. This is usually caused by environmental factors such as direct sunlight, which can cause shrinkage of the seal. Also, powerful chemical cleaners, which could cause damage to the seal.

A replacement sealed double glazed unit will be constructed according to your exact measurements. Once the new sealed unit is installed into the frame of the window then it's time for resealing the edges of your windows. Make sure to use a silicone sealant which is suitable for Australia's weather conditions and can withstand thermal expansion and contraction.

After applying silicone to the edge of the window, use your smoothing tool to press and squeeze the silicone onto the glass surfaces. This will eliminate air bubbles, seal gaps and ensure the bifold door seal repair is secure. Continue to do this on each edge until the entire perimeter of the window is fully re-sealed.
