Replacing Double Glazed Units
Replacing double glazed units is a home improvement task that can drastically reduce heat loss, increase insulation from noise and reduce heating costs. With modern coatings and argon, or krypton gas fills they are also very energy efficient.
The new unit, crafted according to precise measurements, awaits its moment and demands care and precision. This is a moment that is a moment that stops the world and puts your effort into perspective.
Removing the Old Unit
The removal of the old unit is a critical step that will help ensure the new double-glazed window is built to precise measurements. Carefully clean the frame of dust, dirt or old sealant and repair any damage that could be present. Wood filler and sanding may be used to repair minor damage however, major damage might need professional repair.
Once the glass is removed, it is important to measure its width, height and thickness. The most effective method to do this is to remove the glass beads that bind the unit. This is a delicate process that requires patience and prudence. It is recommended to take your time and always make sure to wear safety gear to safeguard yourself from unexpected shards glass and accidental slips.
The best place to start is by removing the bottom bead from the glazing strip using a sharp chisel or an abrasive screwdriver with a wide blade. It is recommended to have someone to hold the sealed window seal repairs unit while you take out all the beads. The unit can easily be thrown off the frame and break.
Once all the beads have been removed, it is important to measure the dimensions of the width, height and thickness of the existing unit.

It can also be used as a reference to ensure that the new unit is sized to fit the frame. This is important because an inadvertent misfit could cause the need to take down and put back together the entire window, but it will also impact its efficiency and performance. This is particularly true in Australia where homes are often exposed to extreme weather conditions.
Preparing the Frame
If you're replacing a fixed window, or a sliding door that has a fixed or opening sash, ensure that the new window is the correct size. upvc window rubber seal replacement near me frames allow very little space for movement and a sealed double glazing unit that's just a few millimeters larger will not be able to fit. Be sure to measure carefully and consult a professional or manufacturer's guide in order to make sure you get accurate measurements.
Once you have a clear idea of the dimensions of your replacement, and are confident that it is correctly fitted remove the glass from its frame. Be sure to work in a well-lit space, and wear safety equipment, such as gloves, to avoid injury from shards of glass. Make use of a putty blade to cut off the glaze stripes or beads that hold the glass to the frame from the perimeter of the pane. The glass is brittle and you must be careful to avoid slipping or stressing the frame.
When the frame is ready to be sealed for the new double glazing unit, ensure that it is in a position to open and close smoothly. It should be a tight fit, but you can alter this if needed by removing or adding packers. If the frame is intended for sliding glass doors it is possible to add additional packers to the top of the hinge and opposite corner to avoid the sash catching when it opens.
Then, clean the frame. Remove any old glazing tape or sealant, if necessary. Examine any damage and make small repairs, if needed, by using wood filler or sanding. A final inspection and cleaning will prepare the frame for replacement sealed double glazing units; my website,, and will give it a fresh look for long-term protection against Australia's harsh climate.
Lifting the New Unit
Over time double glazed sealed units (or a 'sealed unit' as it is commonly known) can develop issues such as moisture in-between panes and/or misting. When this happens the effectiveness of your window can be diminished, letting cold air in and letting warm air from your heating system to escape, leading to higher energy bills and a loss of comfort.
This kind of seal failure is usually the result of aging, general wear and tears or harsh chemical cleaners that degrade the sealing material. However, sometimes the cause is due 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 into place. This is an exciting moment as you've increased the efficiency of your home's heating during the winter months and cooling in the summer while also decreasing your energy bills.
Before securing the unit it is crucial to make sure that the new unit fits properly into the frame. This is essential to avoid damaging the frame and the glass.
If you use sealing tape or glazing tape on your windows, this is the best time to apply a small bead around the perimeter of the glass. This creates a strong barrier that will prevent moisture and air from entering the window. Tighten the sealant with care and ensure it's secure but not tight enough to cause stress on the frame or glass.

Secure the Unit
With the new unit set snugly in the frame and a fresh layer of sealant covering its perimeter This is the moment that marks the end of your project. The unit is now secured to withstand Australia's varying weather conditions, a guarantee for warm temperatures in winter and cool temperatures in summer. It's the moment that validates the accuracy of your measurement and removal, a proof of a product that has been designed according to precise measurements.
Whether a window uses glass beads or screws, fixing the new unit to the frame is an art of balancing tight enough to secure it and soft enough not to strain the glass. If it is too loose, then the window may be unable to total seal repairs its airtight. If it's too tight, it may cause damage to the frame or even warp the material. Each screw must be able to locate its original location, turning just enough to secure the unit without putting too much pressure on it.
This is the final step in a transformational project that enhances the comfort of a home as well as energy efficiency and appearance. With the new double-glazed unit snugly seated in the frame and secured with an all-new layer 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. As opposed to air, argon is less thermal conductivity, which reduces heat transfer through glass. Desiccants also adsorb moisture from the air, which prevents condensation and mould in the frame. The spacer bar is constructed of aluminum and is an essential part of the insulation system. The aluminum bar not only blocks heat transfer but also keeps the edge warm of the window insulated to avoid condensation.
Verifying Your Work
It is crucial to leave the silicone sealant to cure after you have put in the new device. It will take at least 4 hours for it to reach its full strength and provide an impervious barrier. While you wait, take the opportunity to visually evaluate your work and see if you can identify any gaps or issues that could compromise the performance or appearance of the unit.
It's also a great opportunity to check the seals and frames to check for any signs of damage. You can also determine if the whole window needs to be replaced. A damaged seal can affect the efficiency of your home's energy use and can cause drafts or cold spots.
