Our Composite windows can be the same type as our wooden European tilt & turn windows, Flush type windows or stormproof windows, but wooden frame is externally cladded with aluminium.

Timber - Aluminum profile is effective and gives a long-term protection from the negative environment influence.

BUG HOLZPLUS aluminum profile is fixed on the prepared wooden window using new advanced connection system.

Advantages of wooden - aluminium windows:

• The wooden window frame is reliably protected against adverse atmospheric conditions: rain, snow, sunlight.

• The corners are joint by upright cuts. Very good ventilation between wood and aluminum.

• Very good thermal insulation, the first window system that complies with DIN 4108.

• Aluminium screen does not create additional load for hinge mechanisms and becomes integral part of the wooden window components.

• Aluminium profiles support glass packs.

• There are no glazing beads, solid piece of wood can be seen from inside. Therefore the window become even more airtight.

• Four window seals remarkably improve heat and noise insulation.

• Windows are made of glued wood. Outer layers are radially or semi-radially sawn timber and this protects the windows from deformation.

• Wide color palette: RAL colors, as well as anodized colours of aluminum. Easy care of the window surface.
