uPVC Window Gasket Replacement

Over time, window seals can become degraded, causing draughts as well as condensation, as well as a reduction in energy efficiency. Replacing uPVC seals can be an easy DIY project that can save you money.

UPVC window seals are offered in two forms: Flipper/Wedge seal and Bubble gasket. These differ in their design, fit and performance.

Bubble Gasket

Bubble Gasket is a popular form of window seal designed to create an airtight seal when the window or door is closed. This is accomplished through a series 'bubbles, composed of synthetic elastomer or rubber that are positioned along through the length of the seal. These 'bubbles', designed to compress when pressure is applied to the sash and frame, create an ultra-high-performance weather seal that prevents draughts.

There is no adhesive required to put them in place. This makes it a simple and affordable solution to drafty windows as well as reduce your heating bills. As with all window seals, these are susceptible to wear and tear over time. It is therefore a good idea for you to replace them regularly particularly if you notice excessive drafts or air infiltration.

MB DIY stocks a range of flipper, bubble and bubble-flip gaskets to suit your window or door. These are great alternatives to worn gaskets, since they are easy to install and are an affordable solution to keeping your home draught proof and efficient.

In addition to preventing draughts, weathering and air infiltration they also offer other benefits that help to improve the overall performance of your window.

They also provide cushioning for windows, which helps keep them from crashing and squeaking when you close them.

It is crucial to replace bubble gaskets since they'll lose their flexibility with time and could begin to shrink or even disintegrate. The replacement of the gaskets with new ones will ensure that your windows are draughtproof and water-tight.

There are a variety of alternatives to replacing your window gaskets made of upvc, so it's important to spend the time to find the most suitable one for you. Select from a variety of rubber, foam and elastomer seals. There are also wedge and hybrid gaskets designed for specific uses.

Flipper Gasket

If you've noticed drafts or leaks around your windows, it might be time to replace your window gasket. These seals are designed to help to stop air leaks and drafts which can result in more expensive energy bills cold spots, water penetration and noise.

There are a number of different kinds of gaskets available, and it's crucial to find the right one for your home. You should also consider the material of the seal, since certain materials are more suitable for specific applications. A gasket made of rubber, for example, is more durable and can withstand a wide range of temperatures and conditions. It is also easy to clean and is resistant to dirt and grease.

Flipper seals are another kind of gasket for windows. These seals are designed to fit in the gap between the frame and sash when the window is closed. This prevents dust, water and wind from entering your home, and helps reduce costs for energy by creating a better seal. These are available in a range of sizes that will fit most window frames.

Since they are compression seals they are extremely efficient in preventing the leakage of water and air. They come in a variety of colours and are made from rubber or metal. The rollers can be pushed into place using a plastic wheel that runs freely.

Unlike bubble or flipper seals wedge gaskets don't have a profile and are simply wedged into the space between the frame and window. Typically, they are put in place either by hand or using an expert tool that can be bought on the internet.

These tools are extremely helpful for glaziers as they allow them push the flat gasket through the window's groove without having to use ladders. They are available in a variety of sizes, and some come with a pointed end that is used to push the gasket through awkward corners. This can reduce the time required to install a new window and is also used in order to ensure that the gasket is in line with the window frame.

Wedge Gasket

Wedge gaskets cover the gap between the double glazing unit and the upvc frame, preventing the ingress of air, water dirt or other elements from the environment. They are usually made of materials like rubber or synthetic elastomers and have a wedge-shaped shape that is narrower towards the end. Once installed, they are pressed into place to form a tight seal. The wedge-shaped profile is compressed to give an incredibly firm grip and stop unwanted drafts and leaks.

These kinds of draught-seals are commonly found in uPVC doors and windows particularly those with external beading. They are pushed into the groove or channel of the window, doorframe or sash frame, to create a seal. They can be easily replaced when they require removal to clean or repair.


Like all draught proofing seals, the wedge-shaped seal blocks wind from blowing through gaps between double-glazed windows and plastic frames. It also improves the insulation of your home, keeping it warm and saving on heating bills. They also reduce exterior noise pollution and create an obstacle to block the sounds of traffic or neighbours from entering your home.

While they're a popular type of draught seal over time, wedge-shaped draught seals will deteriorate shrink, and become less effective in blocking cold air from entering your home. It is important to replace these seals on a regular basis to ensure they are able to continue to function effectively and keep your home draught-free.

This can be done with an ruler or tape measure but it is recommended that you make multiple measurements to arrive at an average for accuracy.

You can utilize a Kammpro gasket wedge to fill in gaps larger than the original and ensure that fasteners are correctly engaged. The Kammpro gasket can be custom-shaped to accommodate the space and compensate for misalignment of flange, which is perfect for windows with large gaps.

Hybrid Seal

Sealants are available in different types of technology and some are better suited for specific applications such as window & door, gutter or kitchen & bathroom installations. It's not uncommon for contractors to be loyal to a specific brand and not look into other technologies that could solve their sealing needs better. Hybrid sealants are among the technology that are gaining popularity as a snagging option for professional building tradespeople due to their flexibility.

They combine the strength of polyurethanes as well as the silicones' resistance to weathering and provide top performance properties which make them a great choice for construction applications. They are durable weatherproof, paintable, and paintable and can be used in various sealing applications such as expansion joints and splicing joints. They are also non-odour and are suitable for use on wet surfaces.

They stick well to non-porous and porous surfaces like concrete, masonry and brick, drywall, glass, wood, aluminum, galvanized steel, PVC, CPVC pipe fittings, and boat hardware. They can be applied to damp or dried surfaces and at temperatures as low 20F. They are easy to apply with smooth tooling and a quick cure time. This makes them waterproof and ready to paint in only 30 minutes. They are low in VOC and odorless, as well as isocyanate-free and are mildew, mold and fungus resistant.

They are also very durable and UV resistant, as well as weather resistant.  replacing window seal  offer a flexible barrier against air and moisture. They are also low in VOCs and contain a high amount of solids, meaning they will not shrink or break when exposed to extreme weather conditions.

To apply a hybrid sealant cut the nozzle of the sausage or cartridge to the desired size of bead and then apply a continuous band around the perimeter of the frame and siding to create an airtight seal. Use a caulk tool to smooth the bead and ensure it is neat and level. After applying the sealant, let it cure for 24 hours before removing excess using a sharp blade or a scraper.
