S-400 Timber Front Doors

Customers can choose from 36 design options and select between Spruce or Oak wood species. Finishes include stain, oil treatments, or RAL paint, with the possibility of different finishes on the interior and exterior sides. Additionally, a variety of contemporary or traditional door hardware options are available.

The S-400 Series doors are designed to achieve excellent thermal insulation, with U-values as low as 0.7 W/m²K, meeting passive house standards when using the 100mm flush door-to-frame profile.

These doors come equipped with multi-point locking systems as standard. Optional upgrades include keyless entry options, such as fingerprint recognition and smartphone access, enhancing both convenience and security.
