Replacement Double Glazed Units

Double glazed units, or sealed units, as they're known, can be damaged over time. This happens because the insulating qualities of the gasses that insulate the glass panes break down.

When a window has broken down it's important to replace the unit to ensure your home is fully insulated and energy efficient. Fortunately the task is relatively simple and easy to accomplish at home.

Installation

If the window is installed correctly the new unit will fit snugly and will fit comfortably within the frame. If the new unit isn't 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 that it is properly placed. Consult your installer or the instructions from the manufacturer if you're unsure.

To be certain that you are ordering the correct size, it is best to consult a professional or the manufacturer's guide.

Place the new unit into the frame with the assistance of a partner. It is crucial to make this move in a secure place because the glass is fragile and can fall out and break. After the sealed unit is secured in the frame, reattach any packers on the bottom of frame and then put the glazing beads into their original positions. After you have completed this, give the entire window a thorough examination to make sure there are no gaps or misalignments that could affect its performance.

You may also need to add a bead of sealant around the perimeter edge of the frame in order to prevent it from moving in future. It is recommended to re-check the thickness the glass unit.

It's a good idea to clean the seals that have been installed after 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 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 help in cutting them to the required size.

The installation of the sealed unit is simple after the gaskets and frame have been cleaned. It's a good idea to take off the beads (the UPVC frames clips that hold the glasses) and measure them. This will ensure that the seal is built to the correct size, and that there are no gaps around it.

Once the beads are back in their place, you can insert the first bead and move on to the other three. You should be careful not to touch your sealed units for a while following the sealing process as the silicone will need some time to set and become hard before you can handle it again. I usually leave it for about 6 hours prior handling but this could differ based on your silicone sealant's setting time.

Finalization

Sealing and finishing the project is now required once the double-glazed unit has been securely installed within its frame. This is more than just a physical closure to the project; it's an affirmation that your home is prepared to face the elements with a new, secure guardian safely in its place.

This is a standard practice for warm edge sealed unit. Thermoseal Group stocks desiccants as well as manual and automated desiccant dispensing machines.

After the spacers have been filled with the spacers, the glass and frame are sealed with a high-performance silicone, designed to tolerate Australia's harsh climate. This sealant creates an airtight seal that is both flexible and durable, and can expand and contract without breaking. It is crucial to choose the right thickness since any gaps can affect thermal performance. If you're not sure about the proper thickness you should consult an expert or the manufacturer's guidelines.

The final step is to add secondary sealant. It is typically polyisobutylene or another similar material. It's applied to the outside edges of the frame and creates a secondary seal capable of repelling moisture and block air from entering, helping to increase the efficiency of energy.
