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 Envello Shadow Line⁺ cladding board has been moulded from real oak masters and designed to perfectly replicate smooth timber with a flat grained finish, giving a clean authentic look.

The increased width of the Shadow Line⁺ board compared to standard timber boards means there is larger grain detail. This gives an enhanced visual impact, without risk of the board twisting or warping over time.

Tested to the rigorous demands of BS EN 13501-1, the Shadow Line⁺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 unique composition enhances thermal performance.
Integrated UV stabilisers - UV-stabilised 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.
Compatible with Envello Décor aluminium trim (specified separately).

Classification data
Breather membrane	-
Material	Not required. Supplied by others.
Fasteners	Not required. Supplied by others.
Cladding support	-
Counter battens	Not required. Guidance for specification option: Not required for horizontal cladding installations. Supplied by others.
Battens	Supplied by others. Guidance for specification option: Suitable treated timber battens. Main cladding batten: minimum size of 25 x 50 mm. Maximum support centres: 600 mm. Support centres for high load areas: 400 mm. For areas of high wind loading exceeding 1.0 kN/m², severe weather exposure or where exceptional impact loading requirements are anticipated (i.e. low-level applications near pedestrian access, schools, leisure facilities etc.) batten support spacing should be reduced to increase the board stiffness. There should always be battens attached to the wall vertically to allow clear ventilation behind the boards.
Fasteners	Supplied by others. Guidance for specification option: Battens should be fixed to the structural wall using suitable external grade fixings.
Cavity fire barriers	-
Horizontal	Not required. Supplied by others.
Vertical	Not required. Supplied by others.
Weatherboarding	-
Material	Fibre-reinforced resin composite mineral weatherboards. Guidance for specification option: Blend of natural minerals bonded in a polymer resin, with long fibre reinforcement.
