Coastline composite cladding

The next generation composite cladding

Coastline is the newest addition to the Deeplas range. An innovative composite cladding that enhances the appearance of any property, 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. 

  • Specially developed aluminium rail and fixing system
  • 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 colorants that is extruded to give excellent dimensional strength and stability.

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. With the fire safety of exterior cladding under constant scrutiny, Coastline has been rigorously tested and is D rated to BS EN 13501. This means 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 insulation in all approved applications.

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.

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.
