Wood types

In our experience, the most popular choices of wood are pine, meranti, fir, spruce, larch and oak.

The raw material used in our window production is the three-ply laminated glue-lam timber.  Each layer is made of solid wood of approximately 1″ thickness, held together by an impervious waterproof adhesive tested and applied according to the vigorous standards of EN 204 D4 (European norm).

The result is a building material superior to natural wood of the same thickness, with advantages such as:

  • reduction in warping
  • reduction in surface cracks
  • improvement in strength
  • knot-free wood utilized on the cover layers
  • better wood quality on the cover layers
