Aluminium Seals

Seals and Gaskets for all your extrusion needs

Extrudaseal is a leading supplier of flexible extrusions, seals and gaskets for aluminium glazing fabricators. We are able to manufacture and supply a wide range of aluminium seals, all of which are compatible with many of the market leading profile systems, including:

  • Aluk
  • MetalTech
  • Senior Aluminium
  • Smarts

The aluminium industry is going from strength to strength and as a result, the demand for aluminium seals is bigger than ever before. Whilst aluminium has long been the material of choice in the commercial market, over recent years it has became increasingly popular in the domestic and residential sectors thanks to the development of products such as aluminium bi-folding doors and the seemingly limitless colour choice of aluminium doors and windows.

Why buy Aluminium seals and gaskets from Extrudaseal?

Whilst an aluminium fabricator’s Sysco supplies aluminium seals, there are a number of benefits to choosing to buy from Extrudaseal:

  • Our gaskets are as much as 20% cheaper than most Sysco’s – By buying from us, aluminium fabricators could save thousands of pounds a year without compromising on quality. As Sysco’s do not manufacture gaskets and have to buy them in from a separate supplier, it is inevitable that they charge more, even as part of a package deal. As we can manufacture high volume extrusions in-house, we don’t have to increase our prices and there is no middle man involved.
  • More diverse colour choice – In contrast to most Sysco’s, we manufacture and supply gaskets in more than 1,000 RAL colours, including metallic. At Extrudaseal, we pride ourselves on being able to colour match all aluminium seals to our customer’s frames.
  • Innovative and bespoke solutions – Rather than the standard gasket designs that come as part of a package deal, Extrudaseal can design and manufacture a wide range of bespoke extrusions and co-extrusions to suit our customer’s specific requirements.

Aluminium Bi-folding doors

Extrudaseal manufactures a wide range of Bi folding doors rubber seals to suite many of the aluminium window system companies including Smart Architectural Aluminium, AluK, Ikon, Metaltech,Senior Architectural Systems, Kaye Building Systems and many others.

We can also design and produce to customer’s requirements. A typical tool cost is around £500 and depending on volumes Extrudaseal will cover the cost.

All our rubber seals are extruded in either Thermo Plastic Elastomers (TPE)/(TPR) and PolyVinyl Chloride Nitrile (PVC) from British Manufacturers. They also may have an anti stretch polypropylene cord extruded in the rubber gasket to prevent the rubber seal from shrinking.

‘Fit-and-Forget Aluminium Bi-fold Threshold Gaskets

ExtrudaSeal have recently launched a new door seal for use with aluminium bi-folding doors. A common problem with threshold gasket systems for bi-fold doors is that they become misaligned as a result of friction over time, meaning that leafs can catch as they open. To prevent this issue, we have designed an alternative system, the ‘fit-and-forget’ aluminium bi-fold threshold gasket.

‘Fit-and-forget’ threshold gaskets use a unique semi-rigid box foot, providing enhanced weather sealing and a much improved fit when compared with traditional gasket systems. The newly designed gaskets provide an excellent alternative to systems company gaskets in fabrication and are suitable for use with many leading aluminium systems, including ALUK. A further advantage is that ‘fit-and-forget’ aluminium bi-fold threshold gaskets are also suitable for retrofitting.

By eliminating common misalignment issues that can cause threshold gasket systems to kick out and grow worse over time, we have been able to practically eliminate the need for call-backs. Call-backs to realign gaskets can be very time consuming, so by choosing to buy the new ‘fit-and-forget’ system from ExtrudaSeal, as an alternative to package deals from their systems company, aluminium fabricators and installers can stand to save time as well as money.

Extrudaseal is BSI accredited to BS EN ISO9001:2000 Certificate No. FM596948, so our customers can have the peace of mind that all of our products are manufactured and packed to the correct specification, and will be delivered in a timely and orderly manner.
