17 Signs To Know You Work With Double Glazed Sealed Unit Replacement

Why Replace a Double Glazed Sealed Unit?

There's more to it than fixing a damaged glass window when you replace a sealed double-glazed unit. You improve the health and energy efficiency of your home.

Make sure that the work is done correctly and you'll have years of comfort and savings. Making the effort to examine and prepare the frame is essential.

Preparation

Double glazed units, often called sealed units, are an essential element of any Australian home. They can increase comfort and energy efficiency, offer security and lower the noise level by creating an insulating wall between the indoor and outdoor world. However, with time they can start to fail. When this happens it is important to understand the cause of this and the steps to to correct the issue.

In time the inert gases which fill the space between glass panes can escape through cracks or damage. This is called a 'blown' double glazed unit and in this instance, replacing it will be the best solution to restore thermal performance and the air tight seal that stops cold air from escaping into the home.

When replacing the frame, it is important to carefully examine the condition of the frame and ensure it is in good working order. It is essential to repair any damage promptly to avoid further deterioration as well as leaks. It is also crucial to ensure that the sealed unit is the correct size for the frame you have. The UPVC frames have very little tolerance, and if the replacement is even a few millimetres bigger than the frame, it won't fit and will be difficult to put in the right way.

It is recommended to get an acquaintance or a colleague to assist with the removal of the old unit and assist in the installation of the new one. This will ensure that the glass is positioned correctly and the job is done quickly and efficiently.

After the old unit has been removed it is important to wash the entire surface of the frame. This will remove any traces of residue or dirt, prepare the surface for new sealant and ensure that it is ready for a fresh installation of the new unit.

Once the frame and glass have been cleaned it is essential to measure the thickness of the present sealant by using a set calipers (or similar tools). This can be helpful to know before making a purchase for a replacement sealant because it must be of the same thickness to ensure a snug fit into the frame.

Removal

Over time, double-glazed windows, or sealed units as they are also called, can fail. They may become misty or foggy, steamed up or cloudy when the air tight seal that separates the two glass panes fails. This allows moisture to enter and result in calcium deposits that could cause stains on the glass's surface and reduce energy efficiency and allowing cold air into your home.

This can be solved by replacing the double-glazed unit. However, this can be costly and disruptive. An alternative that is less costly and more convenient alternative is to replace gasket seals on the edges of the double-glazed unit. This will restore thermal efficiency, reduce energy bills and improve the acoustics your home.

To do this you must remove the current glass from the uPVC frame. This is hazardous and messy however, with careful consideration and the right tools, you can safely take off the existing glass and be left with an empty frame ready for the new sealant.

Once you have removed the old unit, it is a good idea to clean the uPVC frame thoroughly. This will ensure a clean surface for the new sealant to adhere to. This will also identify any areas that require attention because of wear or damage. Before beginning the replacement process, it's essential to repair any damage or wear. This will affect the performance of the window.

Use a paintbrush to remove dirt and debris from the frame's edges. Also, you should examine the frame for any signs of damage or rot that may need attention. This is an important step to ensure the integrity of your house and ensure that your replacement double glazing functions exactly as it is supposed to.

Installation

Over time double glazing units can fail, or as they are sometimes referred to  as sealed units. The majority of the time, this happens because of a flaw in the airtight seal that is around the edges of the two panes. This allows the gas inert argon to escape from the window which is designed to be insulating. This is not a good thing as it reduces the thermal performance of windows, which increases heating costs substantially. A double glazing replacement system will improve the insulation of your home and reduce your energy bills.

The first step in any sealed unit replacement is to assess the extent of the damage. A careful inspection will reveal issues such as chips, cracks or fogging between glass panes as well as damage to the frame or seals. This will determine if replacing the entire glass is required or if alternative repair options are available.

After the assessment the removal process can begin. It is crucial to ensure that the new window is installed correctly and a high level of craftsmanship is maintained throughout the process. This is especially important during the sealing phase. The appropriate kind of silicone sealant has to be used that can endure Australia's varied weather conditions and not turn soft or break easily.

It is crucial to clean the frame and eliminate all dust and debris before installing the new double-glazed sealed unit. Clean any old sealant using the help of a utility knife or a putty knife. The frame should be ready to receive the new sealed units. Before applying the new silicone sealant, it is a good idea to use caulking remover.

It is essential to accurately measure both the height and width of the unit that is currently in use. A slight error could compromise the fit and cause extra cost. To avoid this, take measurements from a variety of points to account for any slight variations in the frame.

After the installation, you'll need to reseal your frame with silicone caulk. This isn't just an officiality, it's an important step to safeguard the window's new double glazing against Australia's many weather conditions.

Sealing

Double glazing can help keep your home warm during winter and cooler during summer by adding an additional layer of insulation which contains the inert Argon. As time passes the sealed units may fail and leak the insulating gases. This can cause a variety of symptoms, but generally includes a foggy look to the glass and a draft in your home.

To correct this, you will need to replace the sealed unit. You can do this in many ways however the most important thing is to ensure that your new window is of the correct size. This will prevent the glass from breaking.

After removing  replacement sealed units cost  is to accurately measure the length, width and height of the existing unit. This will ensure your replacement is constructed to the correct dimensions and will provide quality and effective level of insulation.

The next step is to apply a new silicone sealant after the replacement sealed unit is correctly size. This is an essential step in resealing a window. It should be done according to the instructions of the manufacturer to ensure that it bonds properly to the window and creates an airtight seal.

When applying the sealant, make use of an instrument to smooth along each edge of the window. This will ensure that there aren't any gaps or uneven areas and will give the window a professional look. After the silicone has dried and dried, you can take pleasure in your newly sealed double-glazed windows, with all the benefits that they bring.
