20 Resources To Make You More Efficient At Replacement Double Glazing Sealed Units
Replacement Double Glazed Units

Installation
If the window has been properly installed, the new window will fit firmly in place and sit comfortably inside the frame. If the new glazed panel is not the same thickness as the old one, you may have to adjust the 'packers' (usually red or bluish plastic slips) within the frame. If you're not sure how to do this then consult your installer or the manufacturer's instructions for guidance.

After the beads have been removed then allow the sealed unit to slide a bit out of the frame. With the help of a person to hold it in place while you measure its size, height and width. This information is essential as it will determine the size of the wedge gasket you need to cut for the brand new double-glazed sealed unit.
Checking
Double glazing units or sealed units, as they are often called and can fail in time. It is usually due to an opening in the seal, which allows condensation and moisture to enter the space between the panes. This can affect the capacity of the window to keep cold air out, and warm generated by the home's heating in, and solar energy from the sun's energy inside.
Failing seals can also cause draughts to be felt inside the home. It is crucial to check your double glazed windows for indications of failure. If you see moisture or misting between the glass, it is a sign that the seal is not working and a new unit should be installed.

Once the sealed unit is secure within the frame, re-attach any packers on the bottom of the frame and then put the glazing beads back in their original position. After you have completed this, give the whole window a visual inspection to ensure there are no gaps or areas of misalignment that could affect its performance.

Sealing
Double glazing can boost the efficiency of your home and provide better sound insulation. However, over time, the seals in the glass can get worn out, leading to misty windows and a reduction in performance. In these cases, replacement is essential. It's a good idea to employ a double glazing expert who can assist you in selecting the most suitable glass products, take precise measurements and ensure that the installation is done correctly.
If you are replacing a sealed unit the first step is clean the frame. Use an old paintbrush (4 inches is the best) to clean the frame, getting rid of dust that has accumulated over time. It's a good idea to clean the new seals after the frame has been cleaned. The easiest way to do this is to lever out the gaskets on the Wedge by placing your fingers on the edge and pulling it out until you reach the point that it overlaps with the friction joint. You should also make notes of the length that you need to make your new seals, as it will be useful when cutting them to size.
After the gaskets have been cleaned and the frame cleaned up it's time to install the sealed unit. To get the best results from this it's a good idea to cut off the beads (the UPVC frame clips that are used to hold the glass) and then take measurements of these. This will ensure that the seal is constructed to the right size and will not leave any gaps around it.
After the beads have been put back in, you can begin with the top one and move down to the other. You should be careful not to touch your sealed units for a while following the sealing process as the silicone will require time to set and harden before you are able to handle it again. I typically leave it for about 6 hours before handling but this could differ based on your silicone sealant's set times.
Finalization
Sealing and finishing the project is now required once the new double-glazed unit has been securely installed within its frame.

The spacer tubes are then be filled with desiccants to absorb any moisture that might be trapped between the two panes during production or over time. This is a common practice for warm edge sealed units. Thermoseal Group stocks a range of desiccants as well as manual or automatic desiccant dispensers.
After the spacers have been filled with the spacers, the glass and frame are sealed using a high-performance silicon, designed to tolerate Australia's harsh climate. This sealant forms an airtight barrier that is extremely flexible and durable, and can expand and contract without breaking. It is essential to choose the right thickness, as any gaps could impact the thermal performance. Consult a professional or the manufacturer's manual for more information on the thickness you should use.
The last step is to apply an additional sealant, usually polyisobutylene (PIB) or similar products. It is applied to the edges of frames to create a secondary seal. It will ward off moisture and block air infiltration, thus increasing the efficiency of the energy.
The frame is then coated with aluminum cladding. This protective coating can withstand the weather and keep your frame looking brand new for a long time. It's a smart investment for the long-term integrity of your home's frame, especially in the case of period or federation homes where wooden frames are susceptible to decay and rot.
