Typical of the cold store and industrial applications where Colorfast is being used, a recent project completed in Trinidad & Tobago.

An innovative roofing and cladding fastener developed by EJOT in the UK more than 30 years ago, and now on its third generation, is becoming increasingly popular with contractors around the world.

Specifications of EJOT Colorfast, which has become the go-to solution in the UK roofing and cladding sector where a colour-matched self-drilling fastener is required, are growing strongly in countries including Australia, New Zealand and the US, as well as in the Caribbean and southeast Asia.

As a typical example, in Australia and New Zealand alone, a steady increase in sales volumes of the FM Approved fastener range has been tracked, with the growth in cold storage applications and insulated panels helping to drive demand here.

In Australasia, an increase in sales volumes has been tracked, with the growth in cold storage applications and insulated panels helping to drive demand.

Feedback received by EJOT UK indicates that many contractors in locations like Australia are adopting new approaches to the design and installation of the building envelope in response to changing building standards, whilst also being able to achieve improved aesthetics and extended design goals.

According to Ben Gallant, Export Sales Manager at EJOT UK, the trend reflects a culture shift that is taking place in how buildings are constructed, with a greater adoption of insulated panels, driven by European influencers, an increased focus on adhering to globally recognised standards such as FM Approvals, and a need to demonstrate supply chain integrity.

Ben says, “If you take the Australasian market as just one example, things operate differently to Europe and the UK in terms of building technology, largely due to established ways of working. But the market is changing. The most recent updates in the building regulations give sustainability a much higher priority and that means specifiers are increasingly choosing insulated panels for the envelope, as well as seeking assurances on long term performance.”

Colorfast CF19 fasteners deployed on Hawke’s Bay Leisure Centre, New Zealand.

One of the factors in Colorfast’s growth may be the influence of contractors who have emigrated from Europe in recent years, taking with them to their newly adopted countries their ways of working and preferred products – which embraces EJOT’s brand strength and product ranges such as Colorfast.

It is a product that is becoming increasingly appealing to cope with the vast range in climatic conditions experienced in countries like Australia and New Zealand, whether in hot or cold locations. Many sites in regions like these present demanding conditions for the building envelope, amplified by the fact that the buildings serve a vast majority of the population who live and work in coastal areas.

As in the UK, Colorfast is also helping contractors in other parts of the world to meet higher thermal standards due to the consistency of the seal above the sheet, maximising the insulation levels that the panels are designed to deliver within the building. Couple this with the head’s reliable UV stability to maintain lasting visual aesthetics and optional stainless steel screws for enhanced corrosion resistance, and it is a product with multiple benefits.

Inside EJOT UK’s Applitec Centre where the quality and performance of Colorfast fasteners is regularly tested.

“Our initiatives to highlight best practice, both for installation tools and correct procedures, are making an impression overseas as well as in the UK,” adds Ben. “For example, we are seeing contractors now making seal testing an integral part of rooftop inspection prior to any additional penetrations that may follow structural completion.

“We like to think being able to offer this kind of practical support makes a real difference, particularly for contractors who are new to Colorfast. They are the ones who can get into the seal testing routine more easily as they don’t have an old habit to break!

“The way we are set up also means that our overseas customers have a strong, direct relationship with the UK team, which gives us the ability to tweak Colorfast for certain customers and create bespoke versions. And, through our global logistics programme we are able to offer dependable supply despite the distance, as well as provide all the technical support, advice and guidance to help our customers succeed.”

EJOT Colorfast fasteners receive globally renowned FM Approved mark

All the most widely used products in the EJOT Colorfast range of colour-matched self-drilling fasteners are now FM Approved, providing specifiers and contractors with another independently verified ‘stamp of approval’.

EJOT has secured FM approval for all the most widely used products in its Colorfast range of colour-matched self-drilling fasteners, providing specifiers and contractors with another independently verified ‘stamp of approval’ for the suitability of the range’s key products when used for fixing sandwich panels, or built-up envelope systems designed to the same standard.

It is a development that provides additional assurance when specifying screws for coloured roofing and façade sheets. Whilst Colorfast’s original metal parent product has long been FM Approved, this latest approval classifies the products in their own right.

The third party certification by FM Approvals, a division of American property insurance giant FM Global, confirms EJOT’s stated performance capabilities for the fasteners in line with the stringent requirements of an international standard that applies to fully tested systems. Under the scheme, every element of the building envelope’s proposed construction is assessed down to the smallest fasteners, which is why it represents the ‘gold standard’ for approvals.

Securing FM Approved status not only means that EJOT has successfully demonstrated Colorfast’s performance in testing, but that assessors are satisfied with how the product is manufactured, the quality of production systems and facilities, and what quality control procedures are in place to maintain consistency, as well as the marking procedures used for identification.

As a result, the standard is unambiguous in terms of which fasteners can be used in order to deliver an approved roof or façade. Where FM approval is a prerequisite on a building envelope project, an FM appointed engineer will make thorough checks to ensure the correct fasteners are being used – from checking approval verifications through to demanding an FM Approved logo on boxes or labelling.

Securing approval, however, is not only subject to successfully demonstrating the product’s performance in testing. The assessment process examines – through annual auditing – how the product is manufactured, the quality of production systems and facilities, and what quality control procedures are in place to maintain consistency, as well as the marking procedures used for identification.

Importantly, achieving the FM Approved mark for Colorfast screws supports EJOT UK’s rapidly increasing export market. Whilst it may not be widely sought currently by clients in the UK, FM Approvals certification is widely recognised and routinely required by specifiers and building inspectors in other countries, including the US, Australia and the south east Asia, where Colorfast sales are growing strongly.

It also represents the latest stage in EJOT UK’s continuous development programme for Colorfast, which means the fastener continues to raise the bar after more than 30 years in the market. Now onto its third generation, Colorfast still outperforms other types of colour-matched screws thanks to its over-moulded nylon head design and the high quality of both the washers and screws, which are available in carbon steel and stainless steel for enhanced corrosion resistance.

Colorfast continues to raise the bar after more than 30 years in the market – now onto its third generation, it still outperforms other types of colour-matched screws thanks to its over-moulded nylon head design and the high quality of both the washers and screws, which are available in carbon steel and stainless steel for enhanced corrosion resistance.

Colorfast joins several other EJOT products for the building envelope that already have an FM Approved mark. These include the Opticore LS, the self-drilling fastener with self-coring integral nylon head that has become a first-choice solution for attaching membrane faced insulated sandwich panels to light steel sections, and the widely used EJOT JT2 and JF3 self-drilling fasteners. In 2022, a range of EJOT flat roofing fastening systems also became FM Approved, most notably the EcoTek tube-washer with FBS-R fastener combination and the TKR/TKE fasteners with the HTK 2G 50 tube-washer.

Details of all EJOT’s FM Approved fasteners are available on RoofNav, a complementary tool from FM Approvals that provides access to the most up-to-date FM Approved roofing products and assemblies.

Brian Mack, Technical Business Development Manager at EJOT UK said: “Securing the FM Approved mark for key products in the Colorfast range is another important stage in the development of this roofing and cladding mainstay, and one that gives additional assurance to the market in respect of its performance capabilities in application.

“The FM Approvals scheme is globally renowned, so this is a strategically significant step for EJOT too as we serve an increasingly international market with Colorfast, catering for projects where the building envelope must accommodate many different climatic conditions and performance goals.

“It is part of our continuous programme to provide customers with the required test evidence and certification they need to make the right choices for the building envelope fastener, whether that’s in the form of FM, ETAs (European Technical Assessments), CE marking or other approvals.

EJOT Colorfast has become the go-to solution for roofing and cladding installations where the head of the screws needs to be matched to the panels it is securing to optimise aesthetics.

Superior durability is achieved through the design and manufacturing process used to over-mould a nylon head, which is extremely UV-stable and can be matched to almost 400 colours in line with recognised colour matching systems.

These include all recognised colour matching systems such as RAL, NCS and Pantone, as well as the British Standards (BS) colour palette, the colour system on which Colorfast was first developed.

EJOT Iso-Corner is ideal for attaching building elements to a façade that is to be treated with an ETICS – external thermal insulation composite systems – or other external wall insulation solution. These could include elements such as railings and Juliet balconies, which require a secure attachment to the load-bearing external wall (substrate) – not the multi-layered external wall insulation system.

Iso-Corner is extremely versatile and suits all insulation depths
Iso-Corner is extremely versatile and suits all insulation depths

The EJOT Iso-Corner concept is simple. It is an L-shape installation angle, available in three sizes and has two installation surfaces so the building element can be fixed to the face or reveal/soffit, which is anchored in to the substrate of the building face. Once in place, the building element is then fixed to the Iso-Corner face with the EJOT Delta PT 100 screws, resulting in a perfectly coordinated fastening system. The Iso-Corner also reduces the risk of thermal bridging because it is manufactured from polyurethane foam.

Iso-Corner is part of a range of innovative mounting elements from EJOT designed to achieve safe, secure and long-term fastening solutions for ETICS / EWI applications. These include:

  • Iso-Spiral Anchor – this spiral-shaped plastic assembly anchor, complete with sealing washer and integrated threaded sleeve, provides a fastening solution for lightweight elements in ETICS facades, such as house numbers and external lights.
