Replacing Double Glazed Units
Double-glazed units can be replaced to lessen heat loss and noise, as well as reduce heating costs. Modern coatings and argon/krypton gas-filled units make them extremely energy efficient.
The new unit, crafted to exact measurements, is waiting for its moment and demands attention and precision. This is the moment when you stop time and puts everything into perspective.
Remove the Old Unit
The removal of the old unit is an essential step to ensure your new double-glazed window is constructed to exact measurements. Clean the frame carefully to get rid of dust, dirt, or old sealant. Repair any damage that is present. Wood filler and sanding may be used to repair minor damages however major damage could need professional repair.
Once the glass is removed, it's important to determine its height, width, and thickness. This can be accomplished by removing the glazing beads that support the unit. This delicate procedure requires patience and prudence. Be patient and wear safety gear to avoid slips and shards.
The best place to begin is to remove the bottom bead from the glazing strip, using a sharp chisel or sharp screwdriver with wide blades. Once the bead has been removed, it's recommended to get help from someone who can hold the sealed unit as you take out the remaining beads. The unit could fall off the frame and break.
After removing all beads, it is essential to determine the width, the height and the thickness of the current unit. The measurements can be used to precisely design the replacement unit you want for your home. It can also be used as a reference to ensure that the new unit is sized correctly for the frame. This is important because a misfit will not only cause the need to remove and reassemble the entire window but will reduce its performance and efficiency. This is especially important in Australia where homes are often exposed to extreme weather conditions.
Preparing the Frame
If you are replacing a fixed sliding door or window using a sash fixed or an opening sash, make sure that the new unit is of the correct size. UPVC frames have very little space for movement, and a sealed double glazing unit that is even a few millimeters too large will simply not fit. Take care when measuring and consult a professional or manufacturer's guide for any necessary measurements.
When you have a clear idea of the dimensions of your replacement, and are sure that it's fitted correctly take the glass out of its frame. Wear safety equipment like gloves and work in an area that is well-lit to avoid injury from glass fragments. Make use of a putty blade to pry off the glazing strips or beads that secure the glass to the frame from the edges of the pane. The glass is fragile, and you should be careful not to slip or straining the frame.
Make sure the frame can open and close smoothly when the new double-glazing unit sealed is installed. It should be a tight fit, however you can adjust this if necessary by removing or adding packers. For instance, if the frame is a sliding door, you may have to add extra packers on the hinge side and opposite corner to prevent the sash from colliding or rattle when it opens.
Then, clean the frame. Take off any old glazing tape or sealant If necessary. Assess any damage, and make minor repairs if necessary using wood filler or sanding. The frame will be refreshed with a final cleaning and inspection and will be able to stand up to the harsh Australian weather for a long time.
Lifting the New Unit
Over time, double glazed sealed units (or a 'sealed unit' as it is often known) may face issues like moisture between panes and/or misting. If this happens, the effectiveness of your window can be diminished and allows cold air to enter and allowing warm air from your heating system out, leading to higher energy bills and a decrease in comfort.
This type of seal failure generally occurs due to age or general wear and tear, or harsh chemical cleaners that degrade the sealing material. However, in some cases, the reason is simply down to expanding and shrinking of the glass in the changing seasons and temperature changes in the home.
After the frame is cleaned and ready and sanded, you can begin lifting the new unit in place. This is an exciting step as you have just increased the efficiency of your home's heating during winter and cooling during the summer months, while also reducing your energy bill.
Before securing the unit it is crucial to ensure that the new unit fits into the frame. A little bit of care in this phase will help prevent any damage to the frame and also the glass.
If you are using glazing tape or sealing tape on your windows, now is the moment to apply a small bead around the perimeter of the glass. This creates a strong barrier that stops moisture and air from entering the window. Make sure to tighten the sealant with care, but not so tightly that it causes stress to the frame or glass. Then, give yourself an ointment for an excellent job, and enjoy your newly installed double-glazed window!
Securing the Unit
This is the time when your work is complete. The unit will be securely placed in the frame and a fresh sealant will be applied around the perimeter. The unit is now secured to withstand Australia's diverse weather conditions, providing for warm temperatures in winter and cool temperatures in summer. This is the moment to confirm your careful measuring and removal, a proof of a unit crafted to exact measurements.
It is important to find the right balance between securing the unit without stressing the glass. If it is too loose, the window may lose its airtight seal. If it's tight enough, it could damage the frame or warp material. Each screw has to find its original location and rotate just enough to hold the unit firmly without putting pressure too heavily on it.
This is the last step in a transformational plan that enhances the comfort of a home, energy efficiency, and appearance. When your work is completed, with the new double-glazed unit securely seated in the frame, and a fresh bead along the perimeter.
The glass panes is filled with the gas argon or with desiccant. Argon is, in contrast to air has a lower thermal conductivity, which decreases heat transfer. In addition the desiccant absorbs moisture from the air, preventing condensation and mould from forming within the frame. The spacer bar, which is typically made of aluminium, is an essential component of the insulating system. The aluminium prevents the transfer of heat, but also keeps the edges of the insulated glass warm to avoid condensation.
Checking Your Work
It is essential to allow the silicone sealant to set once you have installed the new device. It will take at minimum 4 hours for it to reach its maximum force and create an impervious barrier. While you wait, examine your work to determine whether there are any gaps or other issues that could affect the efficiency or appearance.
This is also a great time to examine the frame and seals for signs of damage that require attention, and also to determine whether replacement of the entire window is needed. A damaged seal can have a huge impact on the energy efficiency of your home, leading to cold spots and drafts. It also allows ultraviolet rays to infiltrate the home, causing fade of furniture and reducing the life span of curtains and carpets.
If you are experiencing any of these problems the double glazing might require replacement. Making it a priority to replace it immediately will reduce your energy bills and create a more comfortable and relaxed living space.
Replacing a sealed double-glazed unit is a labor-intensive and technical process that requires the right equipment, careful preparation and precise measurement. It is not an easy DIY project and should be done by a professional with expertise working with uPVC Windows and Doors. They will ensure that the replacement unit is fitted correctly to protect your home from the elements. Replacement rubber gutter seals and experience will ensure that your double-glazed unit is a quiet and efficient blend of warmth in the winter and coolness in summer, shielding your home from the weather.
