Entirely clad in ply, Extra HF is a model of linear elegance: all merit of the design incorporating large horizontal slats, profiled at the top.
Inspired by contemporary principles of architecture, Extra HF complies with the most stringent standards in terms of thermal transmittance for energy upgrading of buildings, thanks to the reduction in thermal bridges between the internal structure and external parts in wood, the overall thickness of the leaf (110 mm) and optimal distribution of the internal insulation material. But the Extra HF up-and-over door is not only stylish and efficient.
The mobile leaf structure and external frame, both in steel, also make this door exceptionally resistant and sturdy. Features that cannot be said of all wooden up-and-over doors.
