Application

Envello cladding is extremely versatile and can be used for most low-level cladding areas as an alternative to timber cladding (subject to building control). Areas include:

  • Residential buildings (under 11 m);
  • Commercial buildings (under 18 m);
  • Garden rooms;
  • Home offices;
  • Furniture;
  • Street furniture;
  • Cycle shelters;
  • Outdoor kitchens.


Envello can be used as the decorative face for most outdoor designs, as long as it is fixed to a structural element. All areas subject to the relevant government regulations/building standards.

Description

The Board & Batten+ composite cladding profile has been moulded from real oak masters with different widths and grain patterns, creating an exclusive balance for both contemporary and traditional designs. With a tongue and groove profile that only requires fixings through the tongue, ensuring the fixing is hidden.

Tested to the rigorous demands of BS EN 13501-1, the Board & Batten+ system achieves a classification of Euroclass D.


Features and benefits:

  • Hand moulded and coloured - Skilfully hand-crafted to ensure a high quality, premium product.
  • Natural wood look - Moulded from selected oak for an organic, realistic wood-grain appearance.
  • UK made, UK backed - Designed and manufactured in the UK, tested independently globally.
  • Fire rated system - Certified to a Euroclass D rating by a UKAS-accredited laboratory.
  • Recycled materials - Recycled materials and renewable biopolymers are used within our boards.
  • Increased thermal performance - The exclusive composition enhances thermal performance.
  • Integrated UV stabilizers - UV-stabilized for better performance and fade resistance over time.
  • Wood free - Wood-free composition prevents rot, warping and insect infestation.
  • Low maintenance - No staining or oiling needed. Only seasonal cleaning required.
  • Impact and weather resistant - Elastomeric surface ensures increased resilience against natural weathering.
  • Mould resistant - Unlike wood, it is actively resistant to mould and fungus.
  • Moisture resistant - Due to the non-porous composition, no sealing is required.
  • Maximum durability - Fibre-reinforced core provides strength and durability whilst reducing weight.
