Installation

If the window seal repair near me is properly installed, the new window will fit firmly in place and sit comfortably inside the frame. If the new glazed unit isn't the same thickness as the previous one, then you might need to adjust the existing "packers" (usually blue or red slips of plastic) within the frame to ensure it is properly positioned. Ask your installer for instructions provided by the manufacturer if you're not sure.

After the beads are removed, allow the sealed unit to drop slightly from the frame. With a helper hold it in place while you measure it accurately height, width and the thickness. This is important as it will determine the dimensions of the wedge gasket you will need to cut for the new double glazed sealed unit.

Checking

Double glazing units, or sealed units as they are often called and can fail over time. It is usually due to leaks in the seal that allows moisture and condensation into the space between the panes. This will affect the ability of the window to keep cold air out, warmth produced by the heating system in, and solar gain from the sun's energy inside.

With the help of a person who holds the new unit gently slide it into place in the frame. This should be done in a safe place as the glass can break if it falls. After the sealed unit is secured in the frame, attach any packers that are on the bottom of frame and then reinstall the glass beads in their original positions. Once you've completed this, give the window a thorough visual inspection to ensure that there are no gaps, and that it is not misaligned.

You may also need to add a bead of sealant around the perimeter edge of the frame to prevent it from moving in future. Reviewing the thickness of the unit is recommended. Double-glazed units are available in different thicknesses. Using the wrong one could have a negative effect on the u value of your home.

You can make use of an old paint brush (4 inch is the best) to sweep the frame out by removing dust and cobwebs that will have built up in the frame over time. It's a good idea to clean the new seals after the frame has been cleaned. It is the easiest way to remove the gaskets that are wedge-shaped from the friction joint by placing your hands on the edge of the gasket and pulling it away. You should also take an outline of the length you require for your new seals since it will be useful when cutting them to size.

Once the gaskets are cleaned and the frame is clean, it's time for the sealed unit. It's a great idea to remove the beads (the UPVC frames clips that are used to hold the glasses) and measure them. This will ensure that the seal is built according to the correct dimensions and will not leave gaps around it.

Once the beads are back in their place, you can insert the first bead and proceed to the remaining three. Be careful not to touch your sealed units for a few minutes afterward as the silicone sealant will need some time to set and harden before you can use it again. I typically wait around 6 hours before handling it, but the silicone sealant's setting time can vary.

Finishing

It's also a good time to assess any damaged areas and make minor repairs, by using wood filler or sanding if necessary. The most serious damage should be taken to an expert to repair.

The spacer tubes will be filled with desiccants in order to take in any moisture that could be trapped between the two panes in the process of manufacturing or over time. This is a standard procedure for warm edge sealed units. Thermoseal Group stocks desiccants as well as manual and automated desiccant dispensing machines.

After the spacers are filled with glass, the frame and glass are sealed with a high-performance silicone specifically designed to withstand Australia's tough climate. This sealant forms a barrier that's durable and flexible, able to expand and contract without becoming brittle or breaking. It's crucial to select the correct thickness, since any gaps can impact the thermal performance. If you're not sure of the right thickness to use seek advice from an expert or a manufacturer's guide.

The last step is to apply secondary sealant, which is typically polyisobutylene (PIB) or similar products. It's applied to edges of the frame's exterior which creates a secondary seal that's capable of repelling moisture and stop air penetration, helping to improve energy efficiency.

The frame is coated with aluminum cladding. This is a coating that is resistant to the elements, keeping your frame looking new for years to come.
