Glazing, Door & Window Seals
Over time the seals around your windows and doors compress, perish and become less effective so need to be replaced. As window seals are designed to create a barrier against outdoor elements, inadequate sealing solutions can negatively affect the overall thermal efficiency of your home. Replacing these seals when they begin to deteriorate is essential for preventing damage to your home, saving you money and keeping you warm and comfortable.
Our glazing, door and window seals are suitable for UPVC, timber and aluminium frames and are available in a range of shapes and sizes to suit the individual application. With an extensive range of sections available, it is possible to choose a replacement product that is an exact match to your existing seal. This allows you to purchase a product that you have confidence in providing a long-term watertight sealing solution.
Glazing seals are typically straightforward to install and do not require ongoing maintenance. They can be pushed into the channel around the edge of the frame by hand without the need for special tools or assistance.
Frequently Asked Questions
Remove the existing seal from your window frame by locating the end of the gasket and gently pulling it out of the channel. After removing the old rubber seal, check around the window frame and remove any debris or other blockages that may stop you from inserting the replacement gasket. Starting in one corner, insert the new seal into the channel working around the window frame. It may be necessary to make a small V cut in the seal to allow it to bend around sharp corners.
Wedge Gaskets: Often used in double-glazed windows, wedge gaskets are designed to hold the glass in place within the frame. They have a unique shape that, when pressed into the gap between the glass and frame, exerts pressure to keep the glass firmly secured.
Bubble Gaskets: These have a round, bubble-like profile and are used to create a seal that can accommodate slight irregularities in the window frame. They are effective in providing a watertight and airtight seal and are commonly used in UPVC windows.
E Gaskets: Named for their E-like profile, these gaskets are used in various window types to provide a seal that cushions the glass within the frame, helping to absorb shocks and reduce noise.
Flipper Gaskets: These feature a unique 'flipper' or fin-like design that provides an extra barrier to air and water. They are often used in conjunction with wedge gaskets in double glazing systems for enhanced sealing.
Brush Seals: These consist of a strip of bristles or a brush-like material, often used in sliding windows or doors. They allow for smooth operation while providing a barrier to dust and drafts.
Timber Weatherseals: These are made from a combination of polyurethane foam and a polyethylene film, creating a durable and weather-resistant seal. They offer excellent thermal and acoustic insulation and are commonly used in residential and commercial windows.
Weathering, such as temperature changes, harsh weather conditions and UV radiation can also shorten the life of your window seal. Moisture may seep into inflections in the seal or surrounding area, causing spots of weakness that may affect the seals integrity. UV also causes rubber to become brittle, increasing the chance of cracking.
Although these external factors can cause your seal to deteriorate, most window seals fail due to the natural aging of the rubber material. Over time, your seals will lose its elasticity and resilience with no way of rejuvenating or bringing them back to new. Understanding these factors will result in less frequent replacements and allow you to maintain and prolong the life of your existing seals.
