Replacing Double Glazed Units

Replacing double glazed units is a home improvement task which can significantly reduce heat loss, enhance the insulation of noise and reduce heating bills. Modern coatings and argon/krypton filled units make them very energy efficient.

The new unit, which was built to exact measurements, is awaiting its time. It needs care and accuracy. This is the moment when you stop the clock and puts everything into perspective.

Remove the Old Unit

Removing the old unit is an essential step that will help ensure your new double-glazed window is built to exact measurements. Carefully clean the frame of any dirt, dust or old sealant, and then repair any damage that might be present. Small repairs can be made with sanding or wood filler however major damage could require professional repairs.

After the glass is removed, it is important to measure its width, height and thickness. This can be accomplished by removing the glazing beads that hold the unit. This delicate process requires patience and caution. It is recommended to take your time and always use safety gear to protect yourself from unexpected shards glass and accidental slips.

The best way to begin is to remove the bottom bead of the glazing strip, using a sharp chisel or sharp screwdriver with wide blades. It is recommended to ask someone to hold the window unit while you take out all the beads. The unit is prone to be thrown off the frame and break.

After all the beads have been removed, it is important to measure the length, width and height of the existing unit. The measurements to build the replacement unit. It can also be used as a guideline to ensure that the new unit is constructed properly for the frame. It is essential to ensure that the window fits properly, as a mismatch will not only need the entire unit to be dismantled and rebuilt, but also reduce its performance. This is particularly important in Australia where homes are often exposed to extreme weather conditions.

Preparing the Frame

If you are replacing a fixed sliding door window that has an opening or fixed sash, make sure that the new unit is of the correct size. UPVC frames have a very limited movement and a double-glazed sealed unit that is a few millimeters larger than the original is not going to fit. To ensure accurate measurements, measure carefully and seek the advice of an expert.

Remove the glass from the frame once you’re sure that the replacement is of the correct size and is properly fitted. Be sure to work in a well-lit location and wear safety equipment, such as gloves, to avoid injury from glass shards. Use a putty knife to pry the glazing strips or beads that secure the glass in the frame from around the edges of the pane. The glass is hard and you must be careful not to slip or straining the frame.

Make sure the frame can open and close smoothly when the new sealed double-glazing unit is installed. It should be a tight fit, but you are able to alter this if needed by adding or removing packers. If the frame is intended for sliding glass doors it is possible to add packers to the top of the hinge as well as the opposite corner to avoid the sash from being caught when it opens.

Then clean the frame. Take off any old glazing tape or sealant If necessary. Check for any damage, and make minor repairs if required using wood filler or sanding. The frame will be refreshed with a final cleaning and inspection, allowing it to withstand Australia’s harsh weather for many years.

Lifting the New Unit

Over time, double-glazed sealed units can experience problems like condensation between the panes or misting. When this happens the effectiveness of your window is diminished, letting cold air in and allowing warm air from your heating system out which can result in the cost of energy and loss of comfort.

This type of failure in seals is usually the result of aging general wear and tear or harsh chemical cleaners that damage the sealing material. However, sometimes the cause is due to expanding and shrinking of the glass during changing seasons and the temperature fluctuations in the home.

Once the frame is clean and ready, you can begin to lift the new unit into place. This is a thrilling step because you’ve made a significant improvement to your home, increasing its warmth during winter and cooling in summer, and helping to reduce your energy bills.

It is crucial to ensure that the new unit is properly fitted in the frame prior to locking it to the frame. This is crucial to avoid damaging the frame and the glass.

If you are using sealing tape or glazing tape on your windows, now is the perfect moment to apply a bead along the perimeter of the glass. This creates a solid barrier that will prevent moisture and air from entering the window. Tighten the sealant with care and ensure it’s secure but not too tight to cause stress on the glass or frame. Enjoy your newly-installed double-glazed windows, and give yourself a pat for the job well done!

Securing the Unit

This is when you are done. The unit will be firmly placed in the frame and a new sealant will be applied to the perimeter. The unit is now secure to withstand Australia’s varied weather, a guarantee of warmth in winter and coolness during summer. It’s the moment that validates the accuracy of your measurement and removal, a confirmation of a unit that was designed to exact measurements.

It is important to find the perfect balance between the need to secure the unit without stressing the glass. If it’s too loose, the unit might be unable to seal its airtight seal. If it’s too tight, it could cause damage to the frame or even warp the material. Each screw has to find its original place, turning just enough to secure the unit without putting too much pressure on it.

This is the final step in a project that can enhance the efficiency of a home’s energy, comfort, and appearance. With the new double-glazed unit firmly seated in the frame and secured with a fresh bead of sealant around its perimeter This is the moment that marks your work’s completion.

The cavity that acts as an insulator between the panes of glass is filled with either argon gas, or a desiccant. In contrast to air, argon has much lower thermal conductivity and reduces heat transfer through the glass. In addition the desiccant absorbs moisture from the air, stopping mould and condensation from growing within the frame. The spacer bar is constructed of aluminium and is an essential part of the insulation system. The aluminium not only prevents heat transfer, but also helps keep the edge warm of the insulated window to avoid condensation.

Be sure to check your work

When you’ve put up the new unit and sprayed a bead of silicone sealant around the edge It is crucial to allow it to set. Don’t disturb it! It will take at least 4 hours for it to attain its full force and create an impervious barrier. While you sit, take the time to look over your work and determine if you can detect any gaps or issues that could impact the efficiency or appearance of the product.

It is also a good moment to inspect the seals and frames for signs of damage that need attention, and to assess whether replacement of the entire window is needed. A damaged seal can have a huge impact on the energy efficiency of your home, causing drafts and cold spots. It can also let ultraviolet rays into the house, causing furniture to fade, and carpets and curtains to wear faster.

If view experiencing any of these problems, your double glazing may need to be replaced. Making it a priority to replace it immediately will lower your energy costs and create a more comfortable and relaxed living space.

It is a technical and labor-intensive job that requires the right equipment, precise measurements and careful preparation. It is not an easy DIY project and should be handled by a specialist who has experience with uPVC Windows and Doors. They will ensure that the replacement unit is installed correctly to protect your home from the elements. Their experience will ensure the double-glazed unit you choose is both quiet and efficient and provides warmth during winter and coolness in summer. This will protect your home from weather damage.
