SHERA plank – a fibre cement plank for traditional architecture
SHERA plank is a unique fibre cement composite of natural fibres bonded tightly in a high-grade silicate structure. This autoclaved wood-grain siding acquires impressive toughness, yet remains flexible and dimensionally stable. It is cellulose cement plank that contains absolutely NO asbestos fibre, no fibre glass fibers nor formaldehyde.

SHERA Plank. Anything Else is Just a Façade.
SHERA Plank is simple to handle and easy to install and is therefore suitable even for the Do-It-Yourself (DIY) segment. SHERA plank is a fibre cement siding and is fire resistant to A2-s1,d0 and made in accordance to EN12467.
SHERA Plank is also water resistant, insect and rot resistant and therefore requires very little maintenance. It is the perfect fiber cement siding for any house that needs a simple, yet durable cladding material. SHERA Plank comes in several sizes and textures to match your housing needs, making it easy to select your desired interior/exterior cladding materials.
It is also a perfect solution for all wood-cladding houses that face a constant threat from termites and water damage since it possesses excellent properties of pest resistance, impact strength and water/moisture resistance. It comes in several sizes and textures and primed planks can be coated before or after installation (double coating) with optional acrylic paint.

Framing and Fixing
Framing: SHERA Plank can be fixed to both timber frames (minimum size 1.5 x 3 inch) or steel frames (thickness between 0.55 and 1.6 mm). Framing must be selected to provide sufficient strength to support the SHERA Plank siding.
Fixing: Planks can be fastened with both nails or screws. It can be nailed directly to timber supports with round wire nails. When using metal screws, the size and length of the screw will be dependent on the thickness of the plank and the gauge of framing. Pre-drilling the plank is a must unless self-embedding, self-drilling head screws such as SHERA FIX-W32G8 are preferred.

Installation
Installation: Fasteners must be located more than 12 mm from plank edges and 20 mm from plank ends. When installing in an overlapping plank cladding style, plank installation must be started at the bottom of the frame. The subsequent row of planks should overlap previous row by at least 25 mm.
Tools: No special tools are required. The product can be used with normal nails, fastened by normal or self-drilling screws and cut by electric power saw with diamond blade.
