Replacement Double Glazed Units

Double glazed units, or sealed units as they're also called, may wear out over time. This typically happens due to the insulating properties of the inert gas that is between the glass panes break down.

When a window has broken down, it's crucial to replace the window to ensure that your home is fully insulated and energy efficient. The task is simple and easy to complete at home.

Installation

If the window was put in correctly, the new window will fit snugly and securely within the frame. If the new window sealant repair near me is not the same thickness as your old one you may need to adjust the 'packers' (usually blue or red plastic slips) inside the frame. If you're unsure of what to do, consult your installer or the manufacturer's instructions for guidance.

A high-quality replacement double-glazed unit is constructed to exacting standards, and should fit into your frame with no hassle. A small mistake can have a major impact on the performance of your window, and must be inspected with care.

Modern double glazed units are a great energy efficient addition to any home. They use an argon gas layer between the panes to provide insulation and thereby reduce the amount of heat that can escape your property during cold weather.

Sometimes, these units develop issues with their seals. This usually occurs when moisture is introduced into the air space of the glass and creates condensation between the panes. The presence of moisture in your window is not only unsightly however it also decreases the efficiency of the glass unit.

Condensation can be caused by a variety of causes. The best method to test for it is to look for a hazy or hazy appearance between your window panes. This is an indication that the seal between two panes has ruptured and moisture is pouring into your living space.

The first step is to remove the glazing beads from around the edges of your window. It can be tricky and a bit messy but is well worth the effort as it lets you access the gasket that holds your glass in place. It is crucial to remove the beads carefully to ensure they don't break. A little help from a friend can be helpful at this stage. 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 holding it in place while you determine its size, height and width. This is important as it will determine the size of the wedge gasket that you will need to cut for the new double glazed sealed unit.

Checking

Double glazing units or sealed units as they are often referred to and can fail over time. This is usually due 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 produced by the heating system in, and solar energy from the sun inside.

Failure of the seal can cause draughts in your home. It is crucial to regularly check your double-glazed windows for indications of failure. The presence of mist or moisture between the glass is a clear indication that the seal has failed and a replacement is required.

It is essential to replace the sealed unit with the proper size. The uPVC frames that the sealed unit sits in have little tolerance for movement so even tiny millimetres of excess can affect the performance of the window. Consult a professional or the guidelines that is provided by the manufacturer to ensure you get the correct size.

Slide the new unit into the frame with the help of a friend. It is vital to do this in a secure spot because the glass is fragile and may break or fall out. Once the sealed unit has been fixed to the frame, attach any packers that are on the bottom of the frame and then put the glazing beads into their original positions. Once you've completed this make sure you give the window an inspection thoroughly to ensure there aren't any gaps and that it is not misaligned.

You may have to add some sealant around the frame's perimeter to prevent it from moving. Checking the thickness of the unit is also an excellent thing to do. This is important as double-glazed units are available in various thicknesses, and if you choose the wrong one, it could affect the u-value of your home's insulation.

Sealing

Double glazing can increase the thermal efficiency of your home and provide better sound insulation. However, over time the glass's seals may be damaged, resulting in misty windows and a decrease in performance. In these instances replacement is required. It's a good idea work with a double glazing professional who will help you select the best glass products, make precise measurements and ensure proper installation.

If you are replacing a sealed unit the first step is clean the frame. Use an old paintbrush (4 inches is the best) to scrub the frame, taking off dust that has built up over time. When the frame is clean, it's a good idea give the new seals a thorough clean too. The easiest method for doing this is to lever out the Wedge gaskets by placing your fingers on the edge, and then pulling it out at the point where it is in contact with the friction joint. Note down the length of time you'll need the new seals. This will help when cutting them.

Installation of the sealed unit is easy once the frame and gaskets have been cleaned. It's a good idea to take off the beads (the upvc door seals replacement frames clips that are used to hold the glasses) and measure the size of them. This will ensure the bifold door seal repair is constructed to the correct size and there aren't any gaps in it.

After the beads have been placed back in, you are able to begin with the top one and move to the lower ones. You should be cautious not to touch the sealed units for a long time afterward, as the silicone sealant will need some time to set and become hard before you can handle it again. I usually leave it for about 6 hours before handling but this could depend on the silicone sealant's setting time.

Finishing

Finishing the project and sealing it is now necessary once the new double-glazed unit is been installed securely within its frame. This step is more than just a physical closure to the project. It's an affirmation that your home is prepared to face the elements with its brand new, secure guardian safely in the right place.

The first step is to clean the frame, by carefully removing any glazing strips or beads that held the old glass. The frame is then cleaned of dirt, sealant or glazing tape. This process also rejuvenates either the aluminium window seal replacement or timber frame. This is also the moment to make any small repairs using wood filler and sanding, if needed. Major damage should be referred to an expert for repair.

The spacer tubes are then be filled with desiccants in order to absorb any moisture that might have been trapped between the two panes during manufacturing or over time. This is a standard procedure for warm edge sealed units. Thermoseal Group stocks desiccants as well as manual and automatic desiccant dispensing devices.

After the spacers are filled and sealed, the glass is then sealed with a high-performance silicone that's designed to withstand the harsh conditions of Australia's climate. This sealant forms an airtight seal that is both flexible and durable, and can expand and contract without breaking. It is essential to choose the correct thickness as any gaps could impact the thermal performance. Consult a professional or the manufacturer's manual in case you're not sure about the thickness to use.

The final step is to add secondary sealant. It is typically polyisobutylene or a similar material. It's applied to edges of the frame's exterior and creates a secondary seal able to repel moisture and block air from entering which can increase energy efficiency.

Then, the frame is completed with aluminum cladding. It's a protective coating that can withstand the elements, and keep your frame looking new for many years to be. This is a smart investment to ensure the longevity and aesthetics of your frames, especially if you have federation or period homes with wooden frames that are susceptible to get rotted.
