This is crucial because it determines the dimensions of the wedge gasket you will need to cut for the brand new double-glazed sealed unit.

Checking

double glazed door seal replacement glazing units, or sealed units as they are commonly called they can break down in time. This usually happens because of a crack in the seal that allows condensation and moisture to get into the space between the panes.

Once you've done this, give the entire window a visual inspection to ensure there are no gaps or misalignments that could compromise its performance.

You may also need to apply a small amount of sealant around the perimeter edge of the frame in order to prevent it from shifting in the future.

Installation of the sealed unit is simple once the frame and gaskets have been cleaned. It's a good idea take off the beads (the UPVC frames clips that serve to hold the glasses) and then measure the size of them. This will ensure that the seal is constructed according to the correct dimensions and will not leave gaps around it.

After the beads are reinserted, you can start with the top one and move down to the other. After sealing the units, you must not touch them for a few hours because the silicone sealant must set and harden. I typically wait 6 hours to handle it, however the silicone sealant's time to set will differ.

Next, the tubes that are used as spacers are filled with desiccants to absorb any moisture that may be trapped between the two panes of glass during manufacture or over time. This is a typical procedure for units with warm edges. Thermoseal Group stocks desiccants as well as manual and automatic desiccant dispensing equipment.

After the spacers are filled, the glass is sealed with a highly-performing silicone that's designed to withstand Australia's harsh climate. The sealant creates a barrier that's both robust and flexible capable of expanding and expand without becoming brittle or breaking. It is essential to choose the right thickness, as any gaps could affect thermal performance. If you're not sure about the proper thickness you should consult a professional or manufacturer's guide.

The last step is to apply secondary sealant, typically polyisobutylene (PIB) or an equivalent product. It is applied to the edges of frames to form a secondary seal. It can repel moisture and stop air infiltration, improving energy efficiency.
