Albio 235 is ideal for wide opening applications, having profiles with great endurance and high moment of inertia. The system presents excellent thermal-insulation properties thanks to the 24-34mm polyamides and special multi-chambered PVC add-ons. Moreover, the system offers water-tightness through EPDM sealing gaskets and its special lift & slide railing mechanism. These fittings give the possibility of using large and thick glazing units, with a capacity that can reach up to 250kg sash weight.
