OPTIWIN LIGNUMA offers a narrow frame, elegant design, and individual colour patterns for interior and exterior. Weather-resistant wood types are ready to withstand the elements and give the window a removable external protection layer. The external layer can be replaced if needed, virtually eliminating the need for surface treatment. The interior layer is made of wood types with favourable density and outstanding static characteristics.

 

OPTIWIN LIGNUMA fully exploits the atmospheric traits of wood. If desired, special wood types such as walnut, zebrawood, or apple can be provided for interior use. Natural oils and thin or thick glazes provide plenty of freedom for individualized colour arrangements. OPTIWIN LIGNUMA is synonymous with cosiness and natural radiance.

OPTIWIN LIGNUMA is also ideal for renovations. With special, individually produced profiles, OPTIWIN can reliably provide solutions for any requirement.

 

OPTIWIN LIGNUMA has an impressive heat transfer coefficient of up to 0.65 W/m2k. This outstanding performance has earned the window system certification as an A-component by the Passive House Institute of Darmstadt.

Four seals and two drainage levels give them exceptional security against wind and weather in addition to outstanding noise protection and thermal comfort.

The frame and glass panes are adhered together for optimal installation and static properties. With OPTIWIN LIGNUMA CLASSIC and OPTIWIN LIGNUMA MODERN the furniture may be visible or hidden in the window design, as desired.
