Replacement Double Glazed Units

Double glazed units, or sealed units, as they’re called, may get worn out over time. This occurs when the insulating properties of inert gases between the glass panes degrade.

It is crucial to replace a damaged window to ensure that your home is energy efficient and insulated. Fortunately the task is relatively easy and straightforward to do at home.

Installation

If the window was installed correctly, the new unit should fit comfortably and firmly inside the frame. If the new unit is not of the same thickness as the older one, then you might need to adjust the existing ‘packers’ (usually red or blue slips of plastic) within the frame to ensure that it is properly positioned. If you are unsure how to do this then consult your installer or the instructions provided by the manufacturer for guidance.

A high-quality replacement double-glazed window is manufactured to the highest standards and should fit your frame with no hassle. A tiny mistake can have a significant impact on your window’s performance.

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

Sometimes, these units may develop problems with their seals. This typically happens when moisture gets into the air cavity of the glass and causes condensation between the panes. The condensation in your window is not just unsightly but also affects the effectiveness of the glazed unit.

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

The first step is to remove the glazing beads around the edges of your window. This can be a little tricky and a bit messy, but it’s worth the effort as it allows you to get access to the gasket that holds your glass in place. It is essential to take care when removing the beads so they don’t break. A little help from a friend can be a good idea at this point. Once the beads are removed allow the sealed unit to fall back slightly out of the frame. With an assistant, hold it in position while you precisely measure the width, height and also the thickness. This is important as it will determine the dimensions of the wedge gasket you need to cut for the new double glazed sealed unit.

Checking

Double glazing units or sealed units as they are commonly called they can break down in time. This is usually due to an opening in the seal that allows moisture and condensation into the space between the panes. This will affect how well the window can keep out cold air, heat generated by the heating system within the home and solar gain inside the window.

Failure of the seal can cause draughts in the home. Double-glazed windows should be examined frequently for indications of failure. The presence of mist or moisture between the glass is a strong indicator that the seal has failed and a replacement unit should be installed.

It is essential to replace the sealed unit with the correct size. The uPVC frames on which the sealed unit is placed have a very small tolerance for movement, meaning that even a few millimetres can alter the performance of windows. To be certain that you’re ordering the right size, it’s recommended to speak with an expert or the manufacturer’s guide.

With a helper holding the new unit gently slide it into place in the frame. It is vital to make this move in a secure spot since the glass is fragile and may fall out and break. After the sealed unit has been fixed to the frame, attach any packers that are on the bottom of frame and then replace the glazing beads into their original position. After you have completed this, give the window an inspection thoroughly to ensure that there are no gaps, and that it is not misaligned.

You may also need to apply a bit of sealant around the perimeter edge of the frame to stop it from moving in future. It is recommended to re-check the thickness of the glass unit. Double-glazed units come in different thicknesses. Using the wrong one can have a negative impact on the u value of your home.

Sealing

Window and Door Seals and Gaskets Replacement bracknell Repair My Windows And Doors glazing can boost the efficiency of your home, and improve sound insulation. However, over time, the glass’s seals can be damaged, resulting in misty windows and a decrease in performance. In these instances replacement is needed. It’s a good idea to employ a double glazing professional who can help you choose the best glass products, take precise measurements and ensure that the installation is done correctly.

The first thing that needs to be done when replacing a sealed unit is to clean the frame. Make use of an old paintbrush (4 inches is the best) to clean the frame, removing dust that has accumulated over time. It’s a great idea clean the new seals once the frame has been cleaned. The easiest way to do this is to remove the Wedge gaskets by putting your fingers on the edge and pulling it out until you reach the point that it overlaps with the friction joint. You should also make a note of the length you need for your new seals as it will help in cutting them to the required size.

After the gaskets have been cleaned and the frame is clean, it’s time to install the sealed unit. It’s a good idea to remove the beads (the UPVC frames clips that hold the glasses) and then measure the size of them. This will ensure that the seal is built according to the correct dimensions and will not leave gaps around it.

After the beads have been placed back in, you are able to begin with the top one and move down to the others. After sealing the units, do not touch them for a few hours because the silicone sealant has to harden and set. I usually wait about 6 hours before handling it, but the sealant’s time to set will differ.

Finalization

After the double-glazed unit is secure within its frame, it’s time to seal and finish. This step is more than a physical conclusion to the project; it’s an assurance that your home is now ready to withstand the elements with its new secure guardian securely in the right place.

The first step is cleaning the frame and taking out any glazing beads strips or other materials used to secure the old glass. The frame is then cleaned of dirt, old sealant, and glazing tape. This process also rejuvenates the timber frame or aluminium frame. It’s also a good opportunity to assess any damaged areas and make minor repairs by using wood filler or sanding as necessary. The most serious damage should be taken to a professional to repair.

The spacer tubes are then be filled with desiccants in order to take in any moisture that could be trapped between the two panes during production or over time. This is a standard procedure for warm edge sealed units. Thermoseal Group stocks a range of desiccants as well as manual or automated dispensers for desiccant.

After the spacers have been filled, the glass and frame are sealed with a high-performance silicone specifically designed to withstand Australia’s tough climate. This sealant creates an airtight seal that is extremely flexible and durable, and can expand and contract without breaking. It is important to use the correct thickness as any gaps could affect thermal performance. If you’re not sure of the right thickness to use, consult with an expert or a manufacturer’s guide.

The final step is adding secondary sealant. It is typically polyisobutylene or a similar material. This is applied along the outside edges of frames to form an additional seal. It can repel moisture and stop air infiltration, thus increasing the efficiency of energy.

The frame is then finished with an aluminum cladding. This is a protective coating that can withstand the elements, keeping your frame looking new for years to be. This is a wise investment to ensure the longevity and the beauty of your home’s frames, especially if you have federation or period style homes with wooden frames that are susceptible to decay.
