You can order our patio doors in six types of wood: Pine, Spruce, Meranti, Larch, Eucalyptus and Oak. Pine is most commonly used in window construction because it has good stability. The hardwoods Larch and Oak are among the hardest types of wood and therefore naturally have a high level of resistance, which makes them resistant to pest infestation, for example. Depending on which wood you choose, you can also choose from up to five environmentally-friendly wood colours that provide additional protection for the surface.
