Installation

If the window was installed correctly, the new window should fit comfortably and firmly inside the frame. If the new glazed window isn't the same thickness that your old one was you may need to adjust the 'packers (usually red or bluish plastic slips) in the frame.

After the beads have been removed, allow the sealed unit to drop slightly out of the frame and with help from a person, keep it in place while you measure it accurately width, height and also the thickness. This information is essential because it will determine the size of the wedge gasket you will need to cut for the double glazed unit.

Checking

Double glazing units or sealed units, as they are commonly called and can fail in time. This normally occurs due to a break in the seal, which allows moisture and condensation to infiltrate the space between the panes.

Once you've done this, give the entire window a thorough inspection to ensure there aren't any gaps or areas of misalignment that could impact its performance.

You may also need to add a bead of sealant to the perimeter edge of the frame to prevent it from moving in the future. It is also a good idea to check the thickness of the glass unit. This is essential since double-glazed units come in various thicknesses, and if you choose the wrong one, it can affect the u-value of your home's insulation.

However, over time the seals in the glass can wear down resulting in misted windows and a decrease in performance. In these cases, replacement bifold door seals is necessary. It is a good idea to work with a double glazing expert who can help you select the best glass products, make precise measurements and ensure proper installation.

When replacing window seals a sealed unit, the first step is clean the frame. Use an old paintbrush (4 inches is ideal) to clean the frame, removing dust that has built up over time. It's a good idea to clean the new seals once the frame has been cleaned. The easiest way to do this is to lever out the Wedge gaskets by putting your fingers on the edge, and then pulling it out until you reach the point that it overlaps with the friction joint. Make a note of the time frame you'll need to use your new seals. This will help when cutting them.

Installation of the sealed unit is straightforward once the frame and gaskets have been cleaned. To get the best results from this it's a good idea to remove the beads (the UPVC frame clips that hold the glass) and then take measurements of these. This will ensure that the seal is made according to the correct dimensions and won't leave any gaps around it.

When the beads are back in their place, you can insert the top bead, and then move on to the other three. Be careful not to touch your 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 usually let it sit for about 6 hours prior to handling, but this can depend on the silicone sealant's setting time.

Finishing

The most serious damage should be taken to a professional for repair.

The spacer tubes are then be filled with desiccants in order to absorb any moisture that may be trapped between the two panes during production or over time. This is a standard procedure for warm edge sealed units. Thermoseal Group stocks a range of desiccants and manual or automated dispensers for desiccant.

After the spacers are filled with the spacers, the glass and frame are sealed using a high-performance silicon, designed to tolerate Australia's harsh climate. This sealant creates an airtight composite door seal replacement that is extremely flexible and durable that can expand and contract without breaking. It's important to use the right thickness, as any gaps could impact the thermal performance. If you're not sure about the right thickness to use you should consult an expert or a manufacturer's guide.

The last step is to apply secondary sealant, which is typically polyisobutylene (PIB) or a similar product. It's applied to outside edges of the frame, where it creates a secondary seal able to repel moisture and prevent air penetration which can improve energy efficiency.

Then, the frame is coated 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. It's a wise investment in the long-term integrity of your home's frame particularly in the case of federation or period homes where timber frames are susceptible to decay and rot.
