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, built to exact measurements, is awaiting its time. It needs care and precision. This is the moment that stops time and puts everything in perspective.
Removing the Old Unit
Removing the old unit is a critical step to ensure your new double-glazed window is built according to precise measurements. Clean the frame thoroughly of any dirt, dust or old sealant and repair any damage that may be present. Wood filler and sanding can be used to repair minor damages however, major damage might require professional assistance.
After the glass is removed, it is important to determine its width, height, and thickness. This can be done by removing the glass beads that hold the unit. This delicate process requires patience and caution. Take your time, and wear safety gear to avoid shards and slips.
The best place to begin is to remove the bottom bead of the glazing strip, with a chisel that is sharp or a an abrasive screwdriver with a wide blade. After the bead is removed, it is advisable to ask for help from someone who can hold the sealed unit as you remove the remaining beads. This is because the device could easily be thrown out of the frame and break.
Once all the beads have been removed, it's important to measure the length, width and height of the unit that is currently in use. You can use the measurements to create the replacement unit. Additionally it will provide a reference for ensuring that the new unit will fit into the frame. This is important because a mistake will not only cause the need to remove and put back together the entire window, but also affect its efficiency and performance. This is especially important in Australia where homes are frequently exposed to extreme weather conditions.
Preparing the Frame
If you are replacing a fixed sliding door window using a sash fixed or an opening sash, make sure that the new unit is of the right size. UPVC frames allow very little space for movement and a sealed double glazing unit that is a few millimeters too big will simply not fit. To ensure precise measurements make sure you measure with care and seek the advice of a professional.
When 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. Be sure to work in a well-lit location, and wear safety equipment such as gloves to avoid injuries from glass shards. Utilize a putty knife to pry off the glazing stripes or beads that hold the glass in the frame, and remove them from the perimeter of the pane. You should avoid slipping the glass or straining frame.
Verify that the frame will be opened and closed smoothly after the double-glazing unit that is sealed is installed. You can alter the fit if needed by adding or removing packing. For instance, if the frame is a sliding door you may need to add additional packers on the hinge's side and in the opposite corners to stop the sash from colliding or rattle when it opens.
Then, clean the frame. Remove any old glazing tape or sealant If necessary. Assess any damage, and make small repairs if necessary by using wood filler or sanding. The frame will be rejuvenated by a final clean and inspection and will be able to endure 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 more commonly called) may develop issues like moisture between panes and/or misting. This can compromise the effectiveness of your windows which allows cold air to pass through and warm air from your heater to escape, leading to high energy bills and discomfort.
This kind of seal failure typically occurs due to aging or general wear and tear or harsh chemical cleaners deteriorating the sealing material. However, in some cases, the reason is due to the expanding and shrinking of the glass in the changing seasons and the temperature fluctuations within the home.
Once the frame is clean and ready, you can begin to move the unit up into its place. This is a very exciting step as you have just improved the heating of your home in the winter months and cooling in the summer months, while also cutting down on your energy costs.
Before securing the unit, it is essential to ensure that the new unit is properly fitted into the frame. window seal repair near me during this stage will help prevent any damage to the frame as well as the glass.
If your windows are fitted with glazing tape or sealant it's time to apply a small bead around the perimeter of the glass and frame, creating a strong protection against air and moisture infiltration. Make certain to tighten the sealant carefully but not so tight that it causes stress to the glass or frame. Then, give yourself an ointment for an excellent job, and enjoy your newly installed double-glazed window!
Securing the Unit
With the new unit seated perfectly in the frame, and a fresh bead of sealant covering its entire perimeter, this is the moment to mark the end of your work. 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 time when your meticulous measuring and removal is confirmed and a confirmation that the unit was built to exact dimensions.
If a window is made of glass beads or screws fastening the new unit to the frame is a delicate balance between tight enough to secure it and soft enough not to stress the glass. If the frame 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 find its original position by turning only enough to secure the unit without applying undue pressure.
This is the last step in a transformative project that enhances the comfort of a home and energy efficiency as well as its appearance. With the new double glazed unit sitting snugly in the frame and securing a fresh bead of sealant around its perimeter, this is the moment to mark the completion of your project.
The insulating cavity between panes of glass is filled with either argon gas or desiccant. Argon is, in contrast to air has a lower thermal conductivity which reduces heat transfer. Desiccants also help to absorb moisture from the air, which prevents condensation and mould in the frame. The spacer bar is made of aluminium and is an essential component of the insulation system. The aluminum blocks the transfer of heat but also keeps the edge of the insulated glass warm to avoid condensation.
Checking Your Work
After you've put in the new unit and put the silicone sealant around the edges it is essential to allow it to set - don't handle it! It takes at least four hours for the silicone sealant to attain its maximum strength and form an impenetrable barrier. While you wait, take the opportunity to examine your work visually and see if you are able to identify any gaps or issues that could compromise the efficiency or appearance of the product.
This is also a good time to examine the frame and seals for signs of damage that require attention, and to assess whether replacement of the entire window is required. A damaged seal can have a significant impact on your home's energy efficiency, causing drafts or cold spots. It also allows ultraviolet rays to infiltrate the home, causing fade of furniture and decreasing the life of curtains and carpets.
If you're experiencing any of these issues, your double glazing may require replacement. Making it a priority to replace it immediately can lower your energy costs and create a more pleasant, relaxed home environment.
