THE OPTIMAL COMBINATION OF THERMAL INSULATION AND WEATHER-RESISTANCE
The Lignum Alu Flat range combines a trendy look with highly resistant aluminium on the outside covering a wooden core with its outstanding thermal qualities – in a natural and environmentally-friendly way.
It offers top thermal insulation up to Ud = 0.91 which makes a huge difference compared to conventional aluminium doors with Ud = 1.5 (approx.).
NEW! The Lignum Alu flat wood/aluminium entrance door is also available in flush design, with frame.
