Coastline composite cladding

The next generation composite cladding

Coastline is an innovative composite cladding that enhances the appearance of any property and it adds up to 10 years of guaranteed weatherproof performance to every exterior. What’s really revolutionary is that Coastline has minimum contraction or expansion, whatever the weather conditions.

  • Foamed composite base material with fire retardant
  • Co-extruded with a UV-stable colour cap with outstanding fade resistance
  • Minimal expansion/contraction
  • Impact tested to rigid profile standards
  • Skin – Acrylonitrile Styrene Acrylate, colour matched to RAL colour ranges
  • Highly weatherable premium embossed matt woodgrain finish
  • Dimensions: 5000mm (length) × 203mm (width) × 5mm (depth)
  • Weight: 5kg per board
  • Visible face when assembled: 167mm in height
  • A pack of 4 boards covers approx. 3.334m² (0.84m² each)*

*(Coverage may differ due to the amount of apertures within the wall construction)

The durability you demand

The secret to Coastline’s hard wearing, long lasting looks and performance is its innovative composite structure – a patented triple composite of polymer resins, inorganic minerals and acrylic colourants that makes it highly temperature stable. So even in extremes of heat and cold, there's almost no explansion or contraction. In addition, it's imune to the rot or insect damage that can afflict conventional timber cladding.


East coast colours, closer to home

Coastline is available in a range of six New England inspired colours: Anthracite Grey, Moondust Grey, Pigeon Blue, Oyster, Soft Green and Taupe.  A realistic matt-effect embossed woodgrain finish adds to the authentic appearance, and through-colouring means any bumps or scrapes are practically invisible from the kerbside.


Now introducing Vertical Coastline cladding

Our new vertical cladding range shares the same advantages as the horizontal Coastline range but offers a sleek flush finish for a more modern appearance. Available in the top three best-selling horizontal colours – Anthracite Grey, Moondust Grey, and Soft Green – the range is complemented by a wide selection of colour-matched aluminum trims to accommodate various installation complexities. Just like the existing trims, these are extruded in aluminum grade 6060 T6, featuring an 80-90 microns powder-coated finish and backed by the Qualicoat Seaside guarantee.

Vertical cladding, recognised as a modern product, is well-suited for newer buildings and can create the illusion of height for single-story structures. Ideal for use in gardens and outdoor projects, it seamlessly blends aesthetic and functional advantages. Its vertical orientation not only adds a touch of modern elegance but also enhances visual appeal while effectively withstanding the most challenging weather conditions.

Safety and sustainability

Our priority has always been the 100% safety of our products, for those who install them and those who live with them in their homes. Coastline is no different. 

Unlike cement board, cutting Coastline panels to length releases no harmful silica dust, which has been linked to several serious respiratory diseases, including lung cancer. Plus, of course, you’ve got the peace of mind that comes from knowing they’re all manufactured to the highest quality standards and fully BBA and BSI accredited.

All the materials used in its manufacture are 100% recyclable. Because it’s made from such a durable, long lasting composite, it never needs painting or treating with preservatives, both of which can contain volatile chemicals that can be harmful to the environment.

Fire safe in all approved applications

With the spotlight firmly on the fire safety of cladding systems in the current climate, you need to be certain the products you specify won’t put those who live with them at risk.

Coastline has been rigorously tested over hundreds of hours to BS EN 13501 certification by Exova Warringtonfire, an independent leading UK authority in fire testing. So you can be confident it conforms to British and European standards in Reaction to Fire and Single Flame Combustibility tests and is certified for use as an exterior wall cladding in all approved applications.*

*Applies to horizontal cladding only

* Coastline cladding is designed for use on buildings with a maximum height of 11 metres and at least 1 metre from boundaries. Failure to install Coastline in accordance to these instructions will invalidate the Product Guarantee.
