Replacing Double Glazed Units
Double-glazed units can be replaced to reduce heat loss and noise, as well as reduce heating costs. Modern coatings and argon/krypton gas-filled units make them very energy efficient.
The new model, designed to exact measurements, is waiting for its moment and demands care and precision. This moment stops the world and puts your efforts into perspective.
Removing the Old Unit
Removal of the old window is a crucial step to ensure your new double-glazed window is built to exact measurements. Clean the frame with care to get rid of dust, dirt, or old sealant. Repair any damage that may be present. Small repairs can be made with wood filler or sanding, while major damage may require professional repairs.
After the glass has been removed, it's important to measure its height, width and thickness. The most effective method to do this is to take out the glazing beads that hold the unit. This delicate process requires patience and caution. It is recommended to be patient and make sure to wear safety gear to safeguard yourself from unexpected shards of glass and accidental slips.
Start by removing the lower part of the glazing strip with a chisel that is sharp, or a wide-bladed screwdriver. After the bead is removed, it is advisable to seek assistance from someone to hold the sealed unit while you remove the remaining beads. The unit can easily fall from the frame and break.
After all the beads have been removed, it is essential to carefully measure the length, width and height of the unit you have. You can use the measurement data to accurately build the replacement unit. It will also serve as a guideline to ensure that the new unit is constructed correctly for the frame. It is important to make sure that the window fits properly, as a mismatch will not only require the whole unit to be disassembled and reassembled but will also affect the performance of the unit. This is especially important in Australia where homes are frequently exposed to extreme weather conditions.
Preparing the Frame
Whether you are replacing a fixed window or a sliding one with a fixed or opening sash, make sure the new window is the right size. UPVC frames allow little room for movement and a sealed double glazing unit that's a few millimeters too large will not be able to fit. Take care when measuring and consult a professional or the manufacturer's guide for any necessary measurements.
Remove the glass from the frame once you are sure that the replacement is of the correct size and is properly installed. Be sure to work in a well-lit location and wear protective equipment like gloves to prevent injuries from glass shards. Use a putty knife remove the glazing beads or strips that hold the glass within the frame, from around the edges of the pane. The glass is hard and you must be cautious to avoid sliding or straining the frame.
Once the frame is ready to receive the brand new sealed double glazing unit, check whether it is capable of opening and closing easily. It should be a tight fit, but you can adjust this if necessary by adding or removing packers. For instance, if the frame is a sliding door you may have to add extra packers on the hinge and at the opposite corner to prevent the sash from colliding or rattle when it opens.
Then, clean the frame. Remove any old sealant or glazing tape, if necessary. Assess any damages and make small repairs with wood filler or sanding if needed. The frame will be refreshed with a final cleaning and inspection so that it can endure the harsh Australian weather for many years.
Lifting the New Unit
Over time, double-glazed sealed units may develop issues like condensation between panes or misting. If this happens, the effectiveness of your window is compromised and allows cold air to enter and letting warm air from your heating system to escape which can result in high energy bills and loss of comfort.
This type of failure in seals is typically caused by aging general wear and tear or harsh chemical cleaners that degrade the sealing material. However, sometimes the cause is due to shrinking and expansion of the glass during the changing seasons and the temperature fluctuations in the home.
After the frame is cleaned and ready, you can begin to lift the new unit up into its place. This is an exciting step that you've created a positive impact on your home, increasing its comfort in winter and cooling in summer, and helping to reduce the cost of energy.
Before securing the unit it's important to ensure that the new unit fits properly into the frame. A little attention in this phase will help prevent any damage to the frame as well as the glass.
If your windows have glazing tape or sealant, now is the time to put a bead around the perimeter of the frame and glass, creating a strong barrier against moisture and air infiltration. Tighten the sealant with care making sure it's secure, but not tight enough to stress the frame or glass. 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 snugly set in the frame and a fresh sealant will cover the perimeter. The unit is now secured to withstand Australia's varied weather conditions, a guarantee for warmth in winter and cooling in summer. It's the moment that validates the accuracy of your measurement and removal, a confirmation of a unit crafted according to precise measurements.
It is important to find the right balance between securing the unit and not overstressing the glass. If it's too loose, the unit may be unable to seal its airtight seal. If it's not tight enough, it could cause damage to the frame or warp material. Each screw must find its original position, turning just enough to hold the unit firmly without applying undue pressure.
This is the last step in a transformative project that improves a home's comfort and energy efficiency as well as its appearance. With the new double-glazed unit firmly seated in the frame and securing a fresh bead of sealant around the perimeter, this is the moment that marks your work's completion.
The glass panes can be filled with either argon or desiccant. Argon, unlike air has a lower thermal conductivity which reduces heat transfer. In addition the desiccant absorbs water in the atmosphere, to prevent condensation and mould from forming in the frame. The spacer bar, which is typically made of aluminum, is an essential part of the insulation system. The aluminium prevents the transfer of heat, but also keeps the edges of the glass insulated warm to avoid condensation.
Verifying Your Work
It is crucial to leave the silicone sealant to set once you have put in the new device. It takes at least four hours for the silicone sealant to reach its maximum strength and create an impenetrable wall. While glass seal repair repairmywindowsanddoors are waiting, take the time to examine your work visually and see if you can detect any gaps or issues that could impact the efficiency or appearance of the device.
This is also a good time to check the seals and frame for indications of damage that require attention, and also to determine whether replacement of the entire window is necessary. A damaged seal can significantly impact your home's energy efficiency, causing drafts or cold spots. It also lets ultraviolet rays in to the home which can cause furniture to fade, and curtains and carpets to wear more quickly.
If you're experiencing any of these problems the double glazing might require replacement. Making it a priority to replace it immediately can lower your energy costs and provide a more comfortable, relaxed home environment.
It is a complicated and labor-intensive procedure that requires the right equipment, precise measurements and careful preparation. It is not a DIY project and should be undertaken by a professional with experience with uPVC Windows and Doors. They can ensure that the replacement unit is installed correctly to shield your home from the elements. Their experience will ensure the double-glazed unit you select is quiet and efficient offering warmth in the winter months and cooling in summer. This will protect your home against the weather.
