20 Things You Need To Know About Replacement Double Glazing Sealed Units

Replacement Double Glazed Units

Installation

If the window has been properly installed, the new window will be firmly seated and will fit comfortably within the frame. If the new glazed window is not the same size as the old one you may need to adjust the 'packers' (usually red or bluish plastic slips) inside the frame. If you are unsure how to proceed, consult your installer or the instructions provided by the manufacturer for guidance.

A good replacement double glazed sealed unit will be made to exacting standards and should fit in your frame with a minimum of hassle. A small error could have a major impact on the performance of your window.

Asking for help can be a good idea at this point. Once the beads have been removed and the sealed unit is free of them, allow it a little to fall out of the frame. With a helper, hold it in place while you determine its size, height and width. This is crucial as it will determine the size of the wedge gasket you need to cut for the new double glazed sealed unit.

Checking

Double glazing units or sealed units, as they are often referred to and can fail over time. This usually happens due to a breach in the seal which allows moisture and condensation to enter the space between the panes. This will affect how well the window is able to block out cold air, heat generated by the heating system inside the home and solar gain inside.

The failure of seals can cause draughts to be felt within the home. It is important to check your double glazed windows for indications of failure. If you see moisture or mist forming between the glass, this is an indication that the seal is not working and a replacement unit must be installed.

Talk to a professional or consult the instructions provided by the manufacturer to ensure you get the correct size.

With a helper holding the new unit gently slide it into place in the frame. It is essential that you make this move in a secure place because the glass is fragile and may fall out and break. Once the sealed unit is securely in the frame, reconnect any packers that are at the bottom of the frame, and then put the glass beads back into their original positions. Once you've done this, give the whole window a visual examination to ensure that there are no gaps or misalignments that could compromise its performance.

It is also possible to apply a bit of sealant to the outer edge of the frame to prevent it from moving in future. It is also a good idea to check the thickness of the glass unit.

The first thing that needs to be done when replacing a sealed unit is to clean the frame. Use a paintbrush from the past (4 inches is ideal) to clean the frame, removing dust that has accumulated over time. Once the frame is clean it's best to give the new seals a thorough clean too. The easiest way to do this is to lever out the gaskets on the Wedge by placing your fingers on the edge, and then pulling it out until you reach the point that it overlaps with the friction joint. You should also take a note of the length that you require to make your new seals, as it will be useful in cutting them to the required size.

Installing the sealed unit is easy once the frame and gaskets have been cleaned. To ensure the best results when doing this, it's recommended to prise out the beads (the UPVC frame clips that are used to hold the glass) and then take measurements of these. This will ensure that the seal is constructed to the correct size and will not leave any gaps around it.

After the beads are in place you can insert the top bead and then work your way round to the remaining three. After sealing the units, do not touch them for a few hours as the silicone sealant has to set and harden. I usually wait about 6 hours before handling it, however the silicone sealant's time to set will differ.

Finalization

It's also a good opportunity to look over any damage and make small repairs by using wood filler or sanding as required. Damages that are severe should be reported to an expert to repair.

The tubes for the spacer are filled with desiccants to adsorb any moisture that may be trapped between the two panes of glass in the course of manufacture or later on. This is a typical procedure for units with warm edges. Thermoseal Group stocks desiccants as well as manual and automatic desiccant dispensing machines.

After the spacers have been filled and sealed, the glass is then sealed with a highly-performing silicone that's designed to withstand Australia's harsh climate. This sealant creates a tight barrier that's strong and flexible that can expand and contract without becoming brittle or breaking. It is essential to choose the right thickness, as any gaps could impact the thermal performance. If you're not sure of the proper thickness seek advice from an expert or a manufacturer's guide.

The final step is to add an additional sealant, usually polyisobutylene (PIB) or an equivalent product. This is applied along the outside edges of frames to create a secondary seal. It is able to repel moisture and prevent air infiltration, improving energy efficiency.

The frame is then finished with an aluminum cladding. This is a protective coating that can withstand the elements, and keep your frame looking new for years to come.
