uPVC Window Gasket Replacement

Over time, window seals could degrade leading to draughts, condensation, and lower energy efficiency. Replacing uPVC window seals is a straightforward DIY project that can save you money on energy bills.

There are two types of window seals made from uPVC: the Flipper/Wedge seal and the Bubble gasket. They differ in their appearance, design, and fit.

Bubble Gasket

Bubble Gasket is a very popular type of window seal designed to create a compression seal when a window or door is closed. This is accomplished by a series of rubber or synthetic Elastomer 'bubbles' which run along the length of the gasket. These 'bubbles', designed to compress when pressure is applied to the frame and sash create an ultra-high-performance weather seal that helps prevent draughts.

They can be easily fitted into a groove in the frame or sash, with no need for adhesive. This is a quick and affordable solution to drafty window problems, and also reduce heating costs. As with all types of window seals, these are susceptible to wear and tear over time, which is why it is recommended to replace them every so often, especially in the case of an excessive amount of drafts or air infiltration.

MB DIY stocks a range of flipper, bubble and bubble-flip gaskets that will fit your window or door. These are excellent replacements for worn and worn out gaskets, as they're easy to install and offer a cost effective solution to keep your home safe from drafts and efficient.

These bubble gaskets not only block air infiltration and draughts, but also improve the performance of your windows. For instance, they could protect your windows from vibrations caused by construction work, wind, and other similar activities. They can also cushion your windows to stop the windows from slamming or creaking as you shut them.

It is crucial to replace bubble gaskets because they will lose their flexibility with time and could begin to shrink or even disintegrate. By replacing them with new ones, you can ensure that your windows are water-tight and secure from draughts.

There are a myriad of options when it comes to replacing your window gaskets made of upvc, so it's important to take the time to choose the right one for you. Choose from a variety of rubber, foam and Elastomer seals. There are also wedge and hybrid gaskets for specialised applications.

Flipper Gasket

If you've noticed drafts or leaks around your windows then it's time to replace the gasket for the window. These seals are designed to help to stop air leaks and drafts which can result in higher energy costs cold spots, water penetration and noise.

There are a number of different gaskets available, and it's important to select the right one for your home. You should also think about the material of the seal, since certain materials are more suitable for certain types of applications. Gaskets made of rubber, for instance, are more durable and can be able to withstand various temperatures and conditions. It is also easy to clean and is resistant to grease and dirt.

Another type of window gasket is flipper seals. These are designed to be placed into the gap between the window frame and sash when the window is closed. This can help to stop water, wind and dust from entering the home, and helps reduce the cost of energy by forming a more effective seal. These are available in different sizes to fit on all window frames.

These gaskets can be very efficient in preventing air and leakage due to the fact that they are generally compression seals. They come in a variety of colors and are made of rubber or metal. They are easily installed by pushing them in place with a plastic roller that is free to run.

As opposed to flipper or bubble seals, wedge gaskets have no profile and are simply inserted into the space between the frame and the window. Typically, they are pushed in place by hand or using an expert tool that can be bought on the internet.


These tools are extremely useful for glaziers, as they allow them to push the flat spline of the gasket into the window groove without having to use ladders. They come in a variety of sizes, and some have a pointed end which is used to push the gasket into awkward corners. This could reduce the time needed to put in a new window and is also used to make sure that the gasket is in line with the frame of the window.

Wedge Gasket

The wedge gaskets serve as a seal between the double-glazing unit as well as the upvc frames to prevent the entry of air, water or dirt. They are typically made of rubber or synthetic elastomers, and have a wedge shape that narrows towards the end. Once installed they are then placed in place to create an impervious seal. The wedge-shaped profile is compressed to provide the necessary grip and to prevent leaks and drafts from escaping.

These types of draught seals are typically found in uPVC windows and doors especially ones with external beading. They are pushed in the groove or channel of the window, doorframe or sash frame to form an airtight seal. They are easily changed in the event that they need to be removed for cleaning or repairs.

The wedge-shaped draught-proof seal as with all other draught-proofing seals available, stops wind gusts from blowing into gaps between double-glazed windows made of plastic frames. It also helps to improve the insulation of your home, keeping your house warm and saving on heating bills. They also reduce exterior noise pollution and provide a barrier to stop the sounds of neighbours or traffic entering your home.

They are a well-known type of draughtseal, but over time, they will degrade shrink, and eventually become less effective in blocking cold air. It is crucial to replace these seals regularly to ensure that they will continue to work effectively and keep your home draught-free.

It is essential to determine the gap between the frame and glass when replacing your uPVC gaskets to ensure you have the correct size seal. You can make use of a ruler or tape measure for this, but it's advised to take several measurements to ensure accuracy.

You can use a Kammpro gasket wedge to fill larger gaps and ensure that fasteners are correctly engaged. The Kammpro can be custom shaped to accommodate the gap and compensate for flange misalignment, which is ideal for large gaps in new or replacement windows.

Hybrid Seal

Sealants are available in different technologies, and some are even better suited for specific applications such as window & doors, gutters, kitchen & bathroom installations. It's not uncommon for contractors to become loyal to a specific brand and not look into other options that can help them meet their job site sealing needs better. Hybrid sealants, because of their flexibility are gaining popularity as a option for snagging among professionals working in the building trades.

They combine the strength of polyurethanes with the silicones' resistance to weathering and provide superior performance characteristics that make them an excellent choice for construction applications. They are tough, paintable, and weatherproof and can be used for various sealing applications such as expansion joints and splicing joints. They also have a low smell and can be applied to damp surfaces.

They adhere well to non-porous and porous surfaces like concrete, masonry and brick, drywall and wood, glass, galvanized steel, aluminum, PVC, CPVC pipe fittings, and boat hardware. They are made for use on dry or wet surfaces and are able to be used in temperatures as low as 20F. They are easy to apply and have smooth tooling and a quick curing time that makes them water-proof and ready for painting in 30 minutes. They are low in VOC and non-odorous, free of isocyanate, and mold, mildew, and fungus resistant.

In repairmywindowsanddoors.co.uk to their outstanding adhesion, they are also robust and UV and weatherproof and offer a flexible barrier against air and moisture penetration. They are also low in VOCs and contain a high amount of solids which means they won't shrink or crack when exposed to harsh weather conditions.

To apply a hybrid sealant cut the nozzle of the sausage or cartridge to the size you want and apply a continuous bead along the frame's perimeter and siding to create an impermeable seal. Make use of a caulk tool smooth the bead and make sure it is clean and level. After applying the sealant, allow it to cure for 24 hours prior to scraping off excess with a sharp blade or a scraper.
