3 Important Benefits of Using Co-Extruded Seals for Windows and Doors

It goes without saying that door and window seals need to be strong and durable, but also flexible. They need to be able withstand moisture and severe weather, helping to seal off the interior, however, they must also be flexible enough to be easily installed and designed to last for a long time. Flexible compounds such as TPE, PVC, PVC nitriles and TPU make ideal extrusion materials due to their flexibility and weather resistance qualities, however, by combining more than one material, an even stronger seal can be created. This is called co-extrusion.

Co-extrusion follows the same principles as single material extrusion process, however, a combination of thermoplastic materials are melted together before being driven through die to form a continuous profile with the combined strengths of each material. Here we discuss three of the most important benefits of using co-extruded seals for windows and doors.

Excellent Weather Sealing Performance

As stated, by co-extruding window seals, the best properties of each material combine to provide an improved weather sealing solution. By dialling in certain amounts of each material, you can design a seal to best suit the conditions that it will face – co-extruded plastic seals can have fantastic weatherability and flexibility, as well as providing good protection for the window panes. Minimal shrinkage is also an important property – co-extruded seals can be designed so that there is no shrinkage when in contact with hot or cold temperatures.

Co-extrusion is very cost effective

Compared with other manufacturing processes, extrusion and co-extrusion are much more cost effective. Whilst the correct dies must be manufactured, the production of extruded and co-extruded parts takes less time than other processes and requires only a minimum level of labour – as a result, costs are kept down.

Co-extrusion provides great quality performance and production efficiency

The co-extrusion production process is simple and with the right tooling, it is easy to produce window seals that exceed quality expectations. Co-extrusion is money well spent; quality window seals will not only provide excellent performance, but will last for a number of years when co-extrusion materials are carefully considered.

As specialists in flexible extrusions, our team and plant are second to none when it comes to producing and advising on co-extruded window and door seals. If you are in need of more information, please call +44 (0)121 356 9733 or email sales@extrudaseal.com.

How Aluminium Fabricators Can Save Money and Access the Best Quality Products

Threshold Gasket

When it comes to buying in gaskets, purchasing them from your systems company can be an expensive way to do business. Why, we hear you ask? Well, because systems companies do not manufacture gaskets themselves, they’re not privy to the exclusive discounts on materials that a specialist plastic extrusion company is.

What’s more, their supplier will have undoubtedly put a mark-up on the materials, which will then be marked up again before being passed on to you. It sounds like an expensive carry on, doesn’t it? It is, and can cost you a whopping 40 per cent more compared to if you buy from a company like us here at Extrudaseal.

With the aluminium sector forecast to grow like never before, thinking smart and buying wisely can help you generate fantastic profits. But if you’re not careful, they can inadvertently spend thousands of pounds that could have lined your pockets.

Still need convincing?

We manufacture phenomenal volumes of extrusions in-house, involve no middlemen and don’t stick a mark-up on our products. Furthermore, in contrast to most systems companies, we manufacture and supply gaskets in more than 1,000 RAL colours, including metallic.

Whether you’re in the glazing industry and need replacement seals and gaskets, or are looking for a range compatible with market leading profile systems like Aluk, MetalTech and Smarts, we have over 600 designs of seal in our range which are suitable for aluminium, timber and uPVC glazing frames and bi-fold doors.
