Replacing Double Glazed Units
Replacing double glazed units is a home improvement project which can significantly reduce heat loss, enhance insulation from noise and reduce heating costs. Modern coatings and argon/krypton gas filled units make them extremely energy efficient.
The new model, designed to exact measurements, awaits its time and requires attention and precision. This moment stops the world and puts your effort into perspective.
Removing the Old Unit
The removal of the old unit is a critical step to ensure your new double glazed window is constructed to the exact measurements. Make sure to clean the frame of any dust, dirt or old sealant and repair any damage that may be present. Wood filler and sanding can be used to repair minor damage, but major damage may need professional repair.
Once the glass has been removed, it is important to determine its width, height and thickness. This can be accomplished by removing the glazing beads that hold the unit. This is a delicate procedure that requires patience and caution. Take your time and wear safety gear to prevent slips and shards.
Start by taking off the bottom of the glazing strip using the sharp end of a chisel or a wide-bladed, sharp screwdriver. It is recommended to ask someone to hold the sealed window unit as you remove all the beads. The unit is prone to fall from the frame and break.
After removing all beads, it is crucial to measure the width, the height, and the thickness of the current unit. You can use the measurements to build the replacement unit. It can also be used as a guide to ensure that the new unit is constructed correctly for the frame. This is important because a mistake will not only result in the need to remove and reassemble the entire window but it will also impact the efficiency and performance of the window. This is particularly important in Australia where homes are often subject to extreme weather conditions.
Preparing the Frame
If you are replacing a fixed window or a sliding door with a fixed or opening sash, make sure your new window is of the correct size. UPVC frames have a very limited movement and double-glazed sealed units that is a few millimeters oversize is not going to fit. Take care when measuring and consult an expert or manufacturer's manual for any necessary measurements.
Once you have a clear idea of the dimensions of your replacement, and are confident that it's properly fitted remove the glass from its frame. Make sure you work in a well-lit location, and wear safety equipment, such as gloves, to avoid injury from shards of glass. Make use of a putty blade to remove the glaze beads or stripes that secure the glass to the frame from the perimeter of the pane. Avoid slipping on the glass or straining the frame.
Check that the frame can open and close smoothly when the new double-glazing unit sealed is installed. You can adjust the fit if needed by adding or removing packing. If the frame is intended for a sliding glass door, you might need to add more packers to the top of the hinge and the opposite corner to prevent the sash catching when it opens.
Then clean the frame. Remove any old sealant or glazing tape If needed. Check for any imperfections and make minor repairs with wood filler or sanding, if required. A final inspection and cleaning will prepare the frame for your replacement, and will give it a fresh look for a lifetime of enduring protection against the harsh Australian climate.
Lifting the New Unit
Over time, double-glazed units can experience problems like condensation between the panes or misting. This can affect the performance of your windows and allow cold air to pass through and warm air from your heater to escape, leading to uncomfortable energy bills and discomfort.
This type of seal failure typically occurs due to aging, general wear and tear or harsh chemical cleaners that degrade the sealing material. However, sometimes the cause is due to shrinking and expanding of the glass during the changing seasons and changes in temperature in the home.
After the frame is cleaned and ready, you can start lifting the frame into the right place. This is a thrilling step, as you've just created a positive impact on your home, enhancing its comfort in the winter months and cooling it in summer, and helping to reduce your energy bills.
Before securing the unit, it is crucial to ensure that the new unit fits into the frame. This phase is important to ensure that the frame isn't damaged and the glass.
If you are using glazing tape or sealing tape on your windows, this is the best moment to apply a small amount of the tape along the edges of the glass. This creates a solid barrier that stops air and moisture from entering the window. Apply patio door seal replacement with care and ensure it's secure but not tight enough to strain the frame or glass. Enjoy your newly-installed double-glazed windows and reward yourself a pat on the back for the job well done!
Securing the Unit
This is when your work is complete. The unit will be firmly set in the frame and a new sealant will be applied to the perimeter. The unit is now secured to withstand Australia's diverse weather which guarantees warmth in the winter months and coolness in summer. This is the moment when your meticulous measuring and removal is validated as a proof that the unit was crafted to exact dimensions.
It is essential to find the right balance between securing the unit without overstressing the glass. If it is too loose, then the window may be unable to seal its airtight. If it's too tight, it could damage the frame or warp the material. Each screw must be able to locate its original position and rotate just enough to ensure that the unit is held securely without applying undue pressure.
This is the last step in a transformational project that improves a home's comfort and energy efficiency as well as its appearance. The moment your work is completed, you will have a brand new double-glazed unit securely seated in the frame, and a new bead adorning its perimeter.
The space between the glass panes can be filled with the gas argon or with a desiccant. Argon is, in contrast to air, has a lower thermal conductivity which reduces heat transfer. Furthermore desiccants absorb moisture in the atmosphere to prevent condensation and mould from forming within the frame. The spacer bar is made of aluminium and is a vital part of the insulation system. Aluminium not only impedes heat transfer, but also helps keep the edge of the window that is insulated to avoid condensation.
Verifying Your Work
It is important that you allow the silicone sealant to set after you have installed the new unit. It will take at least 4 hours for it to attain its full strength and create an impenetrable barrier. While you wait, take the opportunity to look over your work and see if you can spot any gaps or other issues that could compromise the efficiency or appearance of the unit.
It's also a good time to examine the frame and seals to check for any signs of damage and determine if the whole window needs to be replaced. A damaged seal could have a huge impact on the efficiency of your home, causing drafts and cold spots. It can also let ultraviolet rays into the house which can cause furniture to fade and carpets and curtains to wear out more quickly.
If you're experiencing any of these issues it's an indication that your double glazing needs replacing. It will help you save money on your energy bills and create a more relaxed and comfortable living space.
It is a technical and labor-intensive procedure that requires the appropriate equipment, precise measurements and careful preparation. It is not an easy DIY task, and should only be handled by a specialist in uPVC windows and doors who can ensure the correct fitting of the replacement unit to ensure your home is protected from the elements. Their expertise will ensure that the double-glazed unit you choose is both efficient and quiet, providing warmth in the winter months and cooling in summer. This will help protect your home from the elements.
