Why Replace a Double Glazed Sealed Unit?

When you replace the double-glazed seal, you're more than just fixing an unusable window. You're enhancing the health and energy efficiency of your home.

If you perform your job correctly, you will enjoy comfort and savings for many years. It is crucial to spend the time to prepare and check the frame.

Preparation

Double glazed units, also known as sealed units are an essential component of any Australian home. They improve comfort and energy efficiency, offer security and lower noise levels by creating an insulation barrier between the indoor and outdoor world. However, with time they can begin to fail. It is essential to identify the cause and the best way to fix it.

As time passes the inert gases which fill the space between panes of glass may escape from the unit via cracks or breakage. This is called a 'blown' double glazed unit and in this case replacing it is the best option to improve the thermal performance and also to restore the air tight seal that stops cold air from escaping into the home.

During the replacement process it is important to carefully assess the condition of the frame and ensure that it is in good condition. It is important to repair any damage as soon as it occurs in order to prevent further deterioration and leaks of water. It is crucial to ensure that the new sealed unit fits the existing frame. The UPVC frames are extremely tight and when you replace them with something that is even a few millimetres bigger, it will not fit and be difficult to install.

It is an excellent idea to ask an acquaintance or a colleague to help in the removal of the old unit and assist in the installation of the new unit. This will ensure that the glass is set correctly and the job is done quickly and efficiently.

It is essential to clean all the frames' surfaces after taking away the old unit. This will eliminate any residue or dirt and prepare the surface for an entirely new sealant.

After cleaning the frame and the glass, it is essential to determine the thickness (or other instrument) of the sealant. This is important to know prior to making a purchase for a replacement sealant as this will need to be the same thickness to ensure a secure fit within the existing frame.

Removal

Double glazed windows or sealed units, as they are sometimes called, may break down over time. They can become smoky or foggy, steamed up or cloudy as the air tight seal that separates the two glass panes fails. This allows moisture to get in, and can cause calcium deposits to scratch the surface of the glass as well as reduce energy efficiency and allowing cold air to enter your home.

One way to resolve this is to replace the double-glazed unit in itself. This can be expensive and can be disruptive. It is easier and less expensive to replace the seals around the edge of the double-glazed unit. This will improve your home's acoustics, reduce your energy bills and restore thermal efficiency.

To do this, you'll have to remove the old unit from the uPVC frame. It's an unpleasant, hazardous job. But with the right tools and attention you can safely take off existing glass.

After removing the old unit, it is a good idea to thoroughly clean the upvc door seal replacement frames. This will provide a clean surface for the new sealant to bond to. It also will identify any areas that require attention due to wear or damage. Before you begin the replacement process, it's important to fix any damage or wear. This will affect the performance of the window seal replacement.

To clean the frame, use a paint brush to clean any dirt or debris around the edges of the frame. You should also check the frame for any signs of damage or rot that might require attention. This is an essential step to ensure the integrity of your home and ensure that the replacement double glazing sealed units double glazing performs just as it should.

Installation

Over time double glazing units can fail or, as they are also known 'sealed units'. This is usually because of a flaw in the air tight seal that is around the edges of the two panes of glass. This allows the gas inert to escape through the window which is designed to keep it in place. This is not a good thing as it reduces the thermal performance of windows, thereby increasing heating costs substantially. Double glazing will increase the insulation of your home and reduce your energy bills.

The first step in any sealed unit replacement is to evaluate the extent of the damage. A careful inspection can reveal problems such as chips, cracks or fogging between the panes glass, as also damage to the surrounding frame and seals.

After the evaluation, the removal process can begin. It is important to ensure the new window is properly installed and that a high standard of workmanship is observed at all times. This is especially crucial when sealing the window. The appropriate kind of silicone sealant has to be used that can withstand Australia's diverse weather conditions and not become soft or break easily.

It is important to clean the frame and get rid of all debris and dust prior to installing the new sealed double-glazed unit. Remove any old sealant with a utility knife or putty knife. The frame should be ready for the new sealed units. It is recommended to remove the caulking prior to applying the new silicone sealant.

It is crucial to precisely measure the height and width of the existing unit. A tiny error could ruin the fit and lead to additional costs. To avoid this, measure from a number of points to account for any minor variations in the frame.

Once the installation is complete and the frame is in place, it's time to reseal the frame using a silicone caulk. This isn't just a formality, but it is essential to shield the double-glazed window from Australia's various weather conditions.

Sealing

Double glazing can help to keep your home warm during winter and cooler during summer by adding an extra layer of insulation that contains the inert Argon.
