Replacement Sealed Double Glazing Units 101: It's The Complete Guide For Beginners
Replacing Double Glazed Units
Double glazed units can be replaced to reduce heat loss and noise, and also reduce heating costs. With modern coatings and argon or Krypton gas fills they are also extremely energy efficient.
The new model, designed to exact measurements, awaits its place and calls for attention and precision. This is the moment that halts time and puts everything in perspective.
Removal of the Old Unit
It is essential to take out the old unit to ensure that the new double-glazed window has been made to exact measurements. Clean the frame carefully to remove any dust, dirt, or old sealant. Repair any damage that may be present. Sanding and wood filler can be used to repair minor damage however major damage could need professional repair.
After the glass has been removed, it is necessary to measure its width, height and thickness. This can be done by removing the glass beads that support the unit. This is a delicate procedure that requires patience and caution. Be patient, and wear safety gear to avoid shards and slips.
Begin by removing the bottom of the glazing strip using the sharp end of a chisel or a wide-bladed, sharp screwdriver. Once the bead has been removed, it's recommended to seek assistance from someone who can hold the sealed unit as you take out the remaining beads. The unit could be thrown off the frame and break.

Preparing the Frame
If you are replacing a fixed sliding door window that has a fixed sash or opening sash, make sure that the new unit is the proper dimension. UPVC frames offer only a small amount of movement and a double glazing unit that's a few millimeters too big will not be able to fit. Take care when measuring and consult an expert or manufacturer's manual in order to make sure you get accurate measurements.
When you have a clear idea of the dimensions of your replacement and you are sure it is correctly fitted take the glass out of its frame. description here , like gloves and work in a location that is well-lit to avoid injury from glass shattering. Use a putty knife to remove the glazing beads or strips that hold the glass within the frame from around the edges of the pane. You should avoid slipping the glass or straining frame.
Make sure the frame can open and close smoothly when the new double-glazing unit sealed is installed. You can alter the fit as needed by removing or adding packing. If the frame is designed for a sliding glass door it is possible to add additional packers to the top of the hinge as well as the opposite corner to avoid the sash from catching when it opens.
Finally, clean up the frame and remove any old sealant or glazing tape as required. Assess any damage, and make minor repairs if required using wood filler or sanding. The frame will be refreshed by a final clean and inspection so that it can withstand Australia's harsh weather for years.
Lifting the New Unit
Over time, double-glazed sealed units may develop issues like condensation between the panes or misting. This can affect the performance of your windows which allows cold air to enter and warm air from your heater to escape, leading to high energy bills and discomfort.
This type of seal failure is usually the result of aging general wear and tear or harsh chemical cleaners that degrade the sealing material. Sometimes however, the reason can be attributed to the expansion and shrinking of the glass due to temperature fluctuations and seasonal changes.

It is essential to ensure the new piece fits in the frame prior to locking it to the frame. A little attention during this stage can prevent damage to the frame as well as the glass.
If your windows have glazing tape or sealant this is the perfect time to apply a small bead around the perimeter of the glass and frame creating a solid protection against air and moisture infiltration. Tighten the sealant with care and ensure it's secure but not too tight to strain the glass or frame.

The insulating cavity between the panes of glass is filled either argon gas or a desiccant. Unlike air, argon has significantly lower thermal conductivity and reduces heat transfer through the glass. Furthermore, a desiccant adsorbs water in the atmosphere, preventing condensation and mould from growing within the frame. The spacer bar, which is typically made of aluminium is also an essential component of the insulating system. The aluminium not only prevents heat transfer but also keeps the edges warm of the insulated window to prevent condensation.
Be sure to check your work
When you've installed the new unit and sprayed a bead of silicone sealant around the edge it is essential to leave it alone to set. Don't disturb it! It takes at least four hours for the silicone sealant to attain its maximum strength and create an impenetrable barrier. While you wait, visually examine your work to determine if there are any gaps or other issues which could affect the effectiveness or appearance.
