Schulz Italia ASTRA Aluminium casement window

Astra is the new window system in our aluminium line, a revolution in the world of window frames that combines advanced technology and minimalist design.‎ As its name suggests, Astra is a window to the stars, a perfect combination of energy efficiency and aesthetic beauty.‎  Astra window and doorframes are made from ENAW 6060 aluminium profiles, an alloy with high resistance to corrosion in atmospheric environments thanks to QUALICOAT and QUALANOD certified protective painting and sealing procedures.‎ The goal of low thermal transmittance is achieved through the interruption of the thermal bridge - the main antagonist of insulation in window frames - thanks to the structural insertion of continuous 40mm polyamide bars, a material with low thermal conductivity, which guarantees an increase in insulating capacity of over 300%.‎ By means of the open joint pressure compensation mechanism, the presence of a lowered groove and special drainage slots, Astra profiles also guarantee total prevention of water infiltration and prevent the stagnation of any condensation.‎ The depth of the fixed frame profile is 76 mm, while the moving sash profile has a minimum depth of 86 mm.‎ All of the gaskets in our Astra windows are made of EPDM, which in the case of the central seal undergoes a vulcanisation process making this synthetic rubber elastic and difficult to deform, in order to help maintain Astra's high standards of air permeability, water tightness and resistance to wind loads.‎
