New Product Announcement – SealFast U-Channel Gasket

We’re pleased to announce that we’ve expanded our SealFast range with the addition of a new U-channel gasket, that can be used to enhance wind load resistance in windows when used as part of a glazing system.

SealFast has been developed to provide a seal on steel windows and doors or other applications without gasket grooves, and features a robust adhesive strip that means it can be directly applied to a glazing bead.

The U-channel gasket enhances performance by providing increased resistance to wind load, air permeability and drafts by stopping them from passing underneath the glazed IGU.

‘Wind load’ is a term used to refer to all the pressures or forces that the wind applies on a building or structure.  Resistance to wind load is assessed under BS EN 12210. Performance for maximum test pressure is grouped into five classes, with class one the lowest performance and class five being the best.

At Extrudaseal, we’ve produced more than 10,000km of gaskets in the past year alone, along with a wide range of weather seals, Glazepta tapes, U-channels, pressure plates, box sections and bi-folding door seals for leading systems.

To find out how we can help enhance the wind load resistance in your window glazing system, or to speak to us about our range of quality, affordable gaskets, you can call: 0121 356 8733 or email:

Reducing the Number of Call Backs with Quality Bi-fold Door Gaskets

Every installer knows that bad quality equipment can impact their reputation and increase the number of call backs they receive. That’s why many of them are now on the lookout for top quality products that don’t fail and leave them in hot water.

One of the key products taking the market by storm are our fit and forget bi-fold door gaskets, which was designed by our in-house team after listening to the frustrations faced by installers up and down the country.

Launched at the end of 2016, it can be retrofitted and bypass many of the problems associated with usual types of gasket, such as misalignment and ‘kicking out.’ It is also suitable for use with many leading aluminium systems, including ALUK, and provides a secure fix, improves compression and offers better weather sealing.

Thanks to their countless advantages, it’s easy to see why installers are now opting for our bi-fold door gaskets over less reliable options. Paul James, our Sales Director, said: ‘We saw an immediate jump in enquiries for aluminium bi-fold threshold gaskets following June’s heatwave. It’s clearly a time when people want to open-up their doors and make the most of outdoor and indoor spaces.

‘Equally, it’s the time when gaskets can fail, either because they have been caught in opening and closing and are damaged, haven’t been fitted properly or have stuck because of a build of friction on the seal.

‘That means call backs and costs. It’s a source of frustration for so many installers, which is why we developed our solution.

‘Friction on bi-fold gasket seals is a known problem. Even where doors are fitted correctly, a lack of proper maintenance by the homeowner can lead to the build- up, which can lift the gasket out of the threshold or alignment on opening.

‘Silicone lubricant sprays will reduce static build-up. The problem is that in some systems it doesn’t take much to lift the threshold gasket out of position and then it can easily catch as the door rollers pass alongside, the sash passes over or on shoot-bolts.

‘As well as providing improved sealing and compression, the major advantage of our gasket, is the semi-rigid box foot. This provides additional resistance so that even if you get a build-up of static, it doesn’t kick out of place.

‘Customers can also save an average of 30 to 40 per cent, on gaskets by buying product in from ExtrudaSeal, as a third party, compared to buying it from their systems company.

‘Call backs cost installers money. Not just the replacement part but time on site and travel time. This can equate to thousands a year. If you’re a fabricator, it also doesn’t do you any favours with your customers.

‘You shouldn’t be getting call backs on gaskets unless doors haven’t been fitted properly or they have been abused, yet we have spoken to installers who have gone back repeatedly to the same job. The development of our semi-rigid box foot ends this cycle on a wide range of aluminium systems.

Now extruding more than 10,000 km of gaskets in the last year, alongside weather seals, Glazepta tapes and U-channels, pressure plates, box sections and bi-folding door seals for leading systems, plus an extensive ‘back catalogue’ of extrusions, ExtrudaSeal serves fabricators and installers nationwide.

ExtrudaSeal at the FIT Show 2017 – What Stood Out

When we exhibited at the FIT Show in May, one of the things that really stood out was the sheer number of manufacturers looking to reduce their spend without skimping on product quality.

But with manufacturing costs on the rise and customer expectations at a record high, is meeting this demand possible?

Yes, it is

When buying in from a specialist extruder, manufacturers and installers can cut out the middle-man, reduce costs and access better quality products. At Extrudaseal, our gaskets are around 30 to 40% cheaper than other systems companies, which can really add up.

The rise of aluminium

With aluminium doors and windows becoming increasingly popular, the gasket market is thriving. This means that companies like us are producing high volumes, which allows us to reduce the cost of manufacturing before passing on these benefits to the end user.

Keeping ahead of the game with new product development


The new AeroSeal aluminium bi-fold door foam gasket

With a range of gasket manufacturers to choose from, price isn’t the only thing that can give a competitive edge. It’s also about responding to market demand and devising a range of products that come with a range of functions and a variety of colours.

To illustrate the increasing popularity of grey and coloured gaskets, only 16% of gaskets sold in 2015 were grey or coloured, while in 2016 that rose to a quarter. The remainder of those sold were either black or white.

Acknowledging this increase in demand for new and coloured gaskets, our expertly developed range is available in more than 1000 RAL colours. We have also extracted over 20,000km of gaskets in a variety of forms and even launched a new gasket in a high gloss Piano Black finish.

Reacting to the industry trend for aluminium bi-fold doors, we’ve developed AeroSeal, a pioneering, through-colour, aluminium bi-fold door foam gasket that offers the ability to co-extrude with a rigid foot, making it resistant to over-stretching and shrinking.

Our Sales Director, Paul James, said:

‘What we saw at the FIT Show were people looking to reduce overheads but also improved product quality. The market’s growing but it’s also extremely competitive. It’s going to be increasingly important to offer products with USPs.

‘Even the smallest of additional selling points is going to be important in tipping the balance in your favour. Whether that’s more reliable gasket compression, weather sealing or colour finish it’s all about edging ahead.’

If you’re in search of innovative and affordable gaskets, call us today on: 0121 356 8733 to see how we can help.


Keeping Prices Low for our Customers

In an unstable and unpredictable economy, finding new ways of offsetting the extra cost of materials can be a challenge that manufacturers across the country are having to face.

Rising costs of imported raw materials combined with currency weakness means that the industry is having to manage cost pressures that have not always been so tough. Unfortunately, these costs are inevitably passed down from fabricators to installers, and in theory, from installers to consumers.

At ExtrudaSeal, we are always looking for ways to absorb any extra costs in order to avoid price increases for our customers. We do this by constantly evolving to ensure that we are running efficiently and cost effectively.

We are finding that our aluminium seals are becoming more and more popular, thanks to the emergence of aluminium bi-fold doors and windows. Though this might pose a challenge to some manufacturers due to the increased expenses, we see it as a huge field of opportunity and so are willing to absorb extra costs where possible.

To put it into perspective, Figures released by Palmer Market Research show that aluminium is set to reach a 17 year high of topping 220,000 frames within the next three years – exciting stuff if you’re in the business.

During the last year, we have extracted over 20,000km of gaskets in a variety of forms – and even launched a new gasket in a high gloss Piano Black finish.

Chris Byers, our Managing Director, said:

“Whilst we have recently had to increase prices slightly, for 5 years previous, we managed to hold prices despite the increases that we have seen in our own material costs. We achieved this by investing in new efficiencies and processes and we will continue to do our very best to absorb without passing it onto our customers in the future.

“Our customers can save money by buying in from us as a third party. Over the course of a year and with sufficient volume, the savings can fundamentally increase a fabricator’s bottom line.”

If you would like to find out how ExtrudaSeal could help your business shave off its costs, please call 0121 356 8733, or visit us at stand M55 at the FIT Show from 23-25th May.

Exciting New Product Revealed at The FIT Show 2017

FIT show

It’s all systems go at ExtrudaSeal towers, as we prepare to showcase our brand new product at The FIT Show next month.

AeroSeal is a revolutionary, through-colour, aluminium bi-fold door foam gasket that offers the ability to co-extrude with a rigid foot, meaning it cannot be over-stretched or shrink.

Perfectly suited to dynamic applications, its high performance foam technology provides more memory, weather sealing ability and improved acoustic installation when compared with traditional systems.

Not only that, but unlike its competitors that have a ‘skin’ to protect foam, AeroSeal does not show damage because it offers a consistent colour throughout – and with time saving click-and-fit and slide-in installations available, it is sure to go down a storm.

We will also be showcasing our industry-leading range of gaskets and ancillaries at The FIT Show. Why not drop in and see us on stand M55 between 23rd and 25th May?

We serve fabricators and installers nationwide by extruding gaskets, Glazepta tapes and U-channels, weather seals, pressure plates, box sections, bi-folding door seals for leading systems, plus an extensive back catalogue of extrustions.

For more information on how we can cut thousands of pounds off your fabrication or installation costs, please call 0121 356 8733, or email


Exhibiting our Range at the FIT Show 2017

We are really looking forward to exhibiting once again at the FIT Show, which takes place on the 23-25th of May 2017 at the NEC, Birmingham. This is a highly popular UK event that provides companies like ExtrudaSeal- who produce and distribute products, components and services for the manufacture of windows, doors and conservatories, the chance to meet with the people and companies that sell, fabricate and install them.

The annual show is a great opportunity for us to showcase our range of gaskets and ancillary products. As an industry-leading manufacturer, it makes sense for us to ensure that we promote the benefits of fabricators buying gaskets directly, rather than as part of a package deal with their profile systems. The show gives us valuable opportunities to do that by providing one to one time with fabricators from all over the UK under a single roof.

FIT Show Gaskets


As our Managing Director Chris Byers says “The FIT Show is an excellent opportunity for us to demonstrate to fabricators just how much they could stand to save by cutting out the middle man and buying weather sealing components directly from ExtrudaSeal. By dealing with us directly, we estimate that fabricators can save as much as 50%”.

As a constantly improving company, every year we have something new to offer the market. This year is no exception and we are excited to showcase some of our latest innovations, which include our unique ‘fit-and-forget’ aluminium bi-fold door threshold gaskets, complete with semi-rigid PVC foot system for improved fit and weather sealing.

We are eagerly looking forward to the FIT Show in May and hope to share our passion and enthusiasm for gaskets with the very people who rely on them for producing high standard products.

‘Fit-and-Forget’ Threshold Gaskets – Upping Aluminium Bi-Fold Door Performance

Although forecasts for the window and door industry have been bleak as a whole following on from Brexit, the opposite has been the case for the aluminium sector, which is forecast to see growth over the next few years. Aluminium bi-fold doors have certainly increased in popularity over recent years and sales are expected to see a growth of 36% between 2016 and 2019. As a result, aluminium bi-fold doors are a market in which ExtrudaSeal have invested considerably.

Whilst aluminium bi-fold doors are growing in popularity, there is a known problem that threshold gaskets for b-folding doors can ‘kick out’, creating small misalignments or friction that can lead to doors leafs catching as they open. Over time, this misalignment can get worse and as a result, installers receive call-backs to fix the problem, costing people a lot of money over time for repairs and replacement gaskets.

To solve this common issue, prevent call backs and save people money, ExtrudaSeal have recently launched a new ‘fit-and-forget’ aluminium bi-folding door threshold gasket. Suitable for use with a number of leading aluminium systems, including ALUK, this new gasket was developed in house to provide a secure fix, improved compression and weather sealing.

Steve Cockayne, Technical Manager explained “We have designed an alternative threshold gasket system, using a semi-rigid PVC foot, which provides a greatly improved fix over traditional systems as an alternative in fabrication but which can also be retrofitted, eliminating call backs.”

In many cases, threshold gaskets from systems companies will fail in any time from just a few months of use, to years down the line. This leads to time-consuming call-outs for installers and extra costs for customers that could have been avoided. By investing in ‘fit-and-forget’ aluminium bi-folding door threshold gaskets, aluminium fabricators ensure that when choosing bi-fold doors, consumers are much less likely to experience gasket failure.

A further benefit of buying ‘fit-and-forget’ threshold gaskets directly from ExtrudaSeal is that fabricators can stand to save an average of 30-40%, compared to buying from their systems company.

Attention to Detail – Why Colour Matters When Choosing Glazing Seals

Only a few years ago, the choice of colours available for gaskets and glazing seals for the aluminium windows and doors industry was extremely limited. Most consumers were happy with grey gaskets as this was the standard, particularly with white window and door fabrications. However, in 2016 the demand for coloured gaskets has grown dramatically.

coloured glazing sealsOne of the key reasons that grey gaskets were and probably still are the most popular glazing seal colour choice is that for a long time, simple white fabrications have been viewed as the standard choice for aluminium windows and doors. However, there are now many more choices available for window and door fabrications in terms of colour and finish. As well as white, consumers can now choose from a variety of bold colours as well as a range of woodgrain finishes.

The result of the increase in choices available for aluminium profiles is that the consumer is now much savvier than before; they know exactly what they are looking for, so a sale can be lost due to the smallest of details. Whilst grey glazing seals may fit aesthetically with standard white frames, when making a bolder colour choice, consumers want a matching gasket for a complete finish. Whilst the structural functionality of windows and doors play a big part in choosing aluminium, the small detail of a coloured gasket can provide the final impetus for a purchasing decision.

As modern customers are more style conscious than ever before, they are far less likely to compromise. This means that aluminium fabricators simply can’t afford to ignore the importance of coloured gaskets and seals.

The growth of the Aluminium industry

The Aluminium industry continues to grow. Whilst aluminium window and door profiles have been very popular in the commercial and industrial sector for a while, demand in the residential sector has increased considerably in recent times. As residential customers are much more likely to choose a wider variety of colours and finishes when buying new aluminium windows or doors, the result is that the demand for coloured gaskets is increasing considerably.

At ExtrudaSeal, as a UK leader in the flexible extrusions market, we are committed to making sure every little detail is just right. As well as providing coloured glazing seals and gaskets for the aluminium sector in more than 1,000 different RAL colour choices, we also provide a colour matching service.

As well as an amazing choice of coloured gaskets, there are also a number of other benefits for fabricators buying gasket seals directly from ExtrudaSeal rather than as part of a package deal.

What are the Benefits of Triple Fin Wool Pile as a Weather Seal?

Choosing the most effective weather stripping products for doors is important for minimising heat loss in their buildings. An effective wool pile will tightly seal the space between the door jamb and the bottom of the door, whilst minimising air flow between the door and the flooring. This increases thermal efficiency without hindering the door’s ability to open smoothly.

Like other forms of sealing there are factors that can cause wool pile to deteriorate over time, such as extreme temperatures or weather, friction and general wear and tear. Doors in a location with high use, are especially prone to deteriorating over time. However ExtrudaSeal offers superior Triple fin wool pile weatherstrips for maximised, long-lasting sealing effects.


High Performance Wool Pile Weatherstrips

We partnered with TechSeal, a leading manufacturer of wool pile products, to supply premium and innovative weather stripping for a wide range of aluminium, timber and PVCu applications. Triple fin wool pile is a highly effective sealing agent to minimise drafts, maintain internal temperatures and help customers conserve energy. The triple fin weather strips use a centred pile for a consistently tighter seal, and bring a number of considerable benefits when compared with standard wool pile:

  • Because of the three pliable barrier fins of triple fin wool pile, the weather strips can reduce air infiltration by up to 25% in comparison to a single fin.
  • With a uniform structural integrity consistent in triple fin weather strips, they offer more effective sealing against air, moisture, light, dust and pests.
  • As well as air and moisture sealing, the triple fin wool pile features a laminated silent fin providing substantial noise insulation.
  • Triple fin wool pile weather strips also feature a solid polypropylene backing, making them easier to install into window and door frames.
  • Built in pile directors help to prevent the piles from spreading or creating a ‘blooming’ effect, common with regular wool pile.

ExtrudaSeal are an exclusive provider of triple fin wool pile in the UK and supply superior weather seals to a wide variety of specifications. To find out more about triple fin wool pile or to speak to us about your specific requirements, please contact us on +44 (0)121 356 8733 or email
