EJOT Colorfast chosen for Kingspan’s highly sustainable new Asian factory
M
ore than 120,000 EJOT Colorfast self-drilling fasteners have helped Kingspan to create a thermally
superior, visually-appealing building envelope for its first purpose-built manufacturing plant in South East Asia. The 16,000 sq. m factory at Phu My Town in Ba Ria-Vung Tau Province, Vietnam, will enable Kingspan to grow its presence in the wider Asian region by providing a state-of-the-art plant to manufacture its market-leading Quadcore and mineral fibre insulated panels. As a ‘greenfield manufacturing facility’, architects IntES and Kingspan were able to take advantage of a ‘blank canvas’ to design and build a facility with exceptional eco-credentials.
How Colorfast supports zero carbon goals
Installed by main contractor TUAN LE Construction, the building envelope features a total roof area of 14,500 sq. m, formed using Kingspan Quadcore KS1000RW insulated panels and KS1000DLTR (Day- Lite Trapezoidal Rooflight) polycarbonate rooflights. All of the fasteners used to create the envelope were EJOT products, mainly Colorfast over-moulded fasteners which utilise EJOT’s JT3 bi-metallic self-drilling screw. These were coloured in White for the main roof fix and Poppy Red with storm washers for the rooflight detail.
Colorfast was able to make a positive contribution to the long term performance of the building envelope and, hence, the sustainability of the factory as a whole. As an FM Approved fastener, Colorfast has been independently assessed and its performance verified under a globally-recognised certification
can be matched to around 400 colours in line with recognised colour matching system such as RAL, NCS and Pantone, as well as the British Standards (BS) colour palette – the colour system on which Colorfast was first developed.
scheme.
The stringent testing undertaken by FM Approvals considers fasteners within a complete assembly, rather than in isolation, which was extremely important to the architects on this project. Key to Colorfast’s performance is its ability to provide a consistent seal above the sheet, maximising insulation and airtightness as well as reducing the risk of water ingress. The fastener’s head is formed by over- moulding a nylon compound which is precisely formulated to offer reliable UV stability for lasting visual aesthetics. The head
Thermal insulation optimised The JT3 Colorfast fasteners were specified in bi-metallic stainless steel as this material is more suitable for the hot, humid Vietnamese climate than carbon steel fasteners. Stainless steel has the obvious longevity benefit in that it is more resistant to corrosion, but this material choice also offers lower thermal transmission values, meaning heat transfer from the outside to in and vice versa is reduced. Colorfast’s nylon moulded head provides further resistance to thermal transmission, which would not have been the case if powder coated or painted screws were used. The small gains achieved at individual fixing locations added up to a significant benefit over the thousands of penetrations across the roof’s surface.
The end result was the creation of a building which will benefit from a stable internal environment with the lowest levels of energy consumption. This is not only important to the Vietnamese government, which has pledged to achieve net-zero carbon
emissions by 2050, but also to Kingspan as it creates the infrastructure and production facilities required to meet its Planet Passionate goals.

In addition to strategies for reducing water consumption,
cutting landfill waste
utilising only renewable energy to power its operations, the specification of Kingspan’s existing facilities and new buildings will be enhanced. One of the ways this will be achieved is through the use of advanced building materials and components as the new Phu My Town factory demonstrates.
Supporting the expanding SE Asian market EJOT Group
is one of the European
companies responding to serve this growing market, not only in Vietnam but across South East Asia. The Group has already recently invested in opening an office in Singapore and it will shortly be creating a presence in Vietnam to offer local support backed with global technical expertise. This model
has
and
been instrumental
in Colorfast’s evolution from its initial purpose as a UK market-focused product when it launched over 30 years ago, into a fastener with appeal in construction markets around the world. One of the reasons for this is the increased adoption of European building performance standards,
which
have traditionally been regarded as the world’s most demanding, in other continents, particularly Australasia.
