Certificate type
CWCT Certificate
Certificate type
Wood-free composite cladding boards that replicate real timber board and batten.
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.
