Installation

If the window has been installed correctly the new unit will fit firmly in place and fit snugly inside the frame. If the new unit isn't of the same thickness as the old one then you may need to alter the "packers" (usually blue or red slips of plastic) within the frame to ensure it sits properly.

This typically happens when moisture is introduced into the air cavity of the glass, causing condensation between the panes. The presence of moisture in your window is not just unsightly, but it also reduces the effectiveness of the glazed unit.

Once the beads have been removed, allow the sealed unit to loosen a bit of the frame. With the help of a person, hold it in place while you measure its size, height and width. This information is essential because it will determine the size wedge gasket you need to cut for your newly double-glazed sealed units.

Checking

Double glazing units or sealed units as they are commonly called, can fail over time. This normally occurs due to a break in the total seal repairs that allows moisture and condensation to get into the space between the panes. This will affect the ability of the window to keep cold air out, and warm generated by the home's heating in and solar gain from the sun's rays inside.

Seal failure can also cause draughts to be felt within the home. Double-glazed windows should be examined regularly for indications of failure. A misting or a haze of moisture in the glass is a strong indication that the seal has failed and a replacement unit should be installed.

It is important that you replace the sealed unit with the proper size.

Once you've done this, give the entire window a thorough examination to make sure there aren't any gaps or misalignments that could affect its performance.

You may have to add some sealant around the perimeter of the frame to stop it from moving. Re-checking the thickness of the unit is recommended. Double-glazed units come in different thicknesses. Using the wrong one can have a negative impact on the value of your home.

Sealing

Double glazing can improve the thermal efficiency of your home and also improve sound insulation. Over time, the seals on the glass may get worn out, leading to windows that are drooping or misty.

You can use an old paint brush (4 inch is ideal) to clean the frame by removing dust and cobwebs that will accumulate in the frame over time. Once the frame is clean it's a good idea give the new seals a clean too. The most efficient method to do this is to remove the Wedge gaskets by placing your fingers on the edge, and then pulling it out until you reach the point where it overlaps with the friction joint. You should also take an outline of the length that you need for your new seals since it will be useful when cutting them to size.

The installation of the sealed unit is straightforward after the gaskets and frame have been cleaned. To get the best results when doing this, it's recommended to remove the beads (the UPVC frame clips that hold the glass) and then measure these. This will ensure the seal is made to the correct size and there aren't any gaps around it.

After the beads have been placed back in, you are able to begin with the top one and move down to the other. You should be careful not to touch the sealed units for a long time afterward, as the silicone sealant will require time to set and harden before you can handle it again. I typically wait 6 hours to handle it, but the silicone sealant setting time will vary.

Finishing

The spacer tubes are filled with desiccants to absorb any moisture that might be trapped between the two panes of glass in the course of manufacture or later on. This is a common practice for units with warm edges. Thermoseal Group stocks a range of desiccants as well as manual or automatic desiccant dispensers.

After the spacers have been filled with glass, the frame and glass are sealed with a high-performance silicone, designed to tolerate Australia's harsh climate. The sealant creates an airtight barrier that's extremely flexible and durable, and can expand and contract without breaking. It's crucial to select the right thickness, as any gaps could affect the thermal performance. Talk to a professional or consult the manufacturer's manual if you are unsure about the right thickness for your.

The final step involves adding secondary sealant. It is typically polyisobutylene, or a similar substance. It is applied to the edges of frames to create an additional seal. It is able to repel moisture and stop air infiltration, thereby increasing the efficiency of the energy.

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