Benefits of Replacement Double Glazed Units

Double glazed windows (or sealed units) can be misted or  blown when the seals break down which can cause the loss of heat and expensive heating bills. Replacing the unit can create an airtight seal which can reduce condensation and draughts.

The first step would be to use a sealant of high quality that can withstand thermal expansion and contraction.

1. Preparation

Double glazing, also known as sealed units, as they're also known, improve the efficiency of your home and make it more secure by providing a strong security barrier against intruders. They also serve as a barrier against condensation and cold air draughts which could otherwise infiltrate your home.

Check the frame for damage. Small damage can be repaired using wood filler and sanding. Major damage may need professional repair.

It is essential to determine the dimensions of the glass prior to when you put it in.

They function by encapsulating a layer of air between two panes of glass, and the spacer bar is stocked with desiccants that absorb moisture and stop condensation from forming between the glass panes. These features keep the home cool during summer and warm during winter, reducing heating bills and creating an enjoyable living environment.

After the double-glazed window is installed, it will be fixed to the frame with glazing beads or sealant. This is a critical step that ensures the window is sealed and is ready to stand up to Australia's diverse weather conditions, from Tasmania's bracing winds to Queensland's scorching sun.

In order to avoid damaging the new unit, it is essential to place the beads and sealant in a precise manner. It's also essential to choose a sealant of high-quality that is able to withstand thermal expansion and contraction without breaking or becoming brittle.

Double glazed leaks or damaged windows will let heat escape into the air causing your heating system to work harder to maintain the same temperature. A failed sealed unit can allow moisture to get into the air-filled void between the glass panes, which results in condensation.

This is a challenging step because the unit has been steam-steamed and must be removed with care to avoid any damage. It is essential to hold the unit firmly when removing it.
