Enhanced Grain

Enhanced Grain is a stylish, modern board with a contemporary look. The finish of the wood grain has a fine texture. The boards perfectly mimic the subtle nuances of premium oak. This collection is available in various colours.

Weathered Oak

Weathered Oak is an imprint of a weathered oak board more than 100 years old. The coarser finish creates the robust characteristic appearance: timeless and authentic. This collection is available in various colours.


Envello is our cladding and is available in two variants. The Shadow Line mimics smooth wood perfectly. The wider boards have a larger grain pattern, which creates a clean, authentic timber look. Board & Batten are longer boards with different widths and grain patterns. The depth effect adds a captivating dimension to the façade.

Millboard stands for luxury, quality and durability.

Alterwood’s Millboard boards have the look and feel of wood but are maintenance- and splinter-free and UV and weather resistant. The unique composition prevents warping and rotting, while the shades of colour and the wood grain make the boards barely distinguishable from real wood. This makes the boards the perfect alternative to wood in various outdoor applications, such as flooring and façades.
