Sophistication and Functionality

Careful attention to detail and functionality are the two outstanding features of the Double B aluminium/wood range by Buonanno (www. buonannospa.com – www.aluminiumwindows.com), a company founded in 1989. The entire Double B range is tested and certified to provide high thermal performance, minimal energy consumption and conformity to the latest standards (Italian law no. 192/05). The Rubino model from the Double B aluminium/wood series for example, is an open-joint system with thermal transmittance of Ufl = 3.49 W/m2K and Uc = 2.90 W/m2K; Topazio, a vertical sliding model with a gasket closure with carriage, offers Ufc = 3.49 W/m2K; Uc = 2.90 W/m2K; the Smeraldo Evolution thermal break model and Smeraldo Superthermal model have Ufl = 2.70 W/m2K; Ufc = 2.09 W/m2K and Ufl = 2.17 W/m2K; Ufc = 2.15 W/m2K respectively. Diamante, a model with outward opening mechanism with one or two leaves and optional panic lock device or push-bar for public places, or a more basic window handle, offers Ufl = 2.86 W/m2K; Uc = 3.59 W/m2K. The versatility of this range, with fixtures and finishes for both wood and aluminium, makes it a solution suitable for any type of design requirement.
