Boxes are either made of double inner aluminium walls filled with polyurethane foam or aluminium sheets bent in 45’ degrees or extruded. The polyurethane is CFC free, meaning eco-friendly while offering thermal insulation and sound resistance.
Aluminium boxes are available in various RAL colors as well as wood imitations, in order to satisfy all architectural applications, traditional or modern.
They can be placed over the window / door frame or externally, while they are easy to be installed or repaired in case of damage.
The aluminium boxes can be operated either manually by a strap, lace, crank mechanism or electrically by tubular motor.
