lumber is based on an authentic natural look. A homogeneous wood grain lends the building envelope a strong depth effect. Similar to wood, the facade panels have a multi-layered effect, but unlike wood, they do not require additional weather protection.

The appearance of the new slate texture is based on slate slabs and their natural layers. A unique light refraction occurs at the edges of the rock layers, causing them to stand out to varying degrees depending on the angle the light hits. Since light conditions change over the course of the day, the facade with this texture has a different appearance depending on the time of day.

Irregular lines playfully run across the slabs like ribbons. The combination of straight and angled, partially overlapping lines of different sizes creates an exciting visual effect on the facade. The flow of the lines harmoniously integrates into the overall picture.

The natural imperfection and visual irregularity of the vintage panels give the facade a unique appearance and above all individuality, since no slab is like any other.

luce silver

The addition of mica gives the facade a glittering, shimmering appearance. Depending on how the sunlight falls, the particles reflect in different ways and create unique effects. This is definitely the texture for individual highlights.

terrazzo black

The coarse, dark grain gives this slab a individual look. A special surface treatment lends the texture a unique speckled appearance, which forms an exciting contrast especially with light colours. terrazzo black gives the facade a discreet two-tone effect.

glossy (Interior)

The exquisite texture is an interior highlight and an elegant eye-catcher. The shiny surface reflects the light and creates a new space effect. The slabs have a different look depending on how the light falls. This texture particularly emphasises the vivid surface characteristic of concrete with its interplay of colour shades and cloud effects. The natural appearance of the material changes over time, giving each panel a unique look.
