Why You Should Focus On Improving Replacement Sealed Double Glazed Units
Benefits of Replacement Double Glazed Units
If the seals fail, double-glazed windows or sealed units may be misted (or "blown"), resulting in heat loss and expensive heating bills. Replacing the unit can restore an airtight seal which can reduce condensation and drafts.
The first step is to choose the highest-quality sealant that will be tolerant of thermal expansion and contraction.
1. Preparation
Double glazing, or sealed units, as they are commonly referred to, increase the efficiency of your home and increase its security by providing a solid protection against intruders. They are also a good barrier against condensation and cold air drafts that could otherwise get into your living space.

After you've cleaned the frame it's time to prepare it for your new sealed double-glazed unit.
Depending on the style of window, there are a variety of methods to achieve this. If your window design incorporates glazing tape, wrap it around the frame's edges to create a cushioned bed for the glass to rest upon. If you have an edge warmer you'll also require a desiccant-filled spacer tube. This will absorb any moisture that might have been trapped in the manufacturing process, and eventually found its way to the window.
2. Removal
Double glazed units, or sealed units as they're also called, can break down over time. In this instance the inert gases that are in the space between the glass panes could escape. This can have a negative impact on the temperature regulation and the efficiency of your home's energy use.

This will eliminate any dust or debris that might have accumulated in the frames over time. Check the frame for damage. Minor damage can be repaired with wood filler and sanding. The more serious damage could require professional repair.
Before you place the glass in its spot, it is crucial to measure it accurately. If you are comfortable doing it yourself using straight edges and a ruler. Once you have the measurements you can then begin to re-fit the glazing beads.
This is a delicate process since the glass could easily break and fall out, therefore it is crucial to do this process right. When you are finished carefully re-fitting the glazing beads it is crucial to make sure that the glass is completely flush with the frame. This will prevent any moisture from causing condensation between the panes.
3. Installation
Modern replacement double glazed units, also known as sealed unit windows, offer numerous benefits for homeowners, including improved energy efficiency. The spacer bar is stuffed with desiccants, which absorb moisture to stop condensation between the glass panes. These features keep the house warm in the winter and cool in summer, reducing heating and cooling bills and creating a comfortable living environment.
Once the new double glazed unit is fitted it can be fixed to the frame with glazing beads or sealant. This is a critical step that ensures the window is sealed and ready to withstand Australia's varied weather conditions from Tasmania's fierce winds to Queensland's scorching sun.
In order to avoid damaging the new unit, it is essential to place the beads and sealant with care. It's also important to use a high-quality sealant that is able to withstand thermal expansion and contraction without breaking or becoming brittle.

Double glazed leaks or damaged windows can let heat escape into the surrounding air, causing your heating system to perform harder to maintain the same temperature. A damaged or leaking sealed unit could also allow moisture to enter the air-filled void in between the glass panes, which results in condensation.
