– EPS box with a density of 40 kg / m3 min., no metal reinforcement, fully insulated. Removable section for maintenance on the outside with a 140mm. width.
– Shoulders in high-density (min. 45 kg / mc) EPS dimensioned after the window/wall hole, designed to fit the frame in the parapet with a thickness of 65 mm.
– Lowerside (if shown) made of high density (min. 60 kg / mc) EPS with integrated gradient and lapel/stopper raised from the frame.
All elements of the subframe will be glued to obtain a perfect sealing between the individual components.
The overall depth of the subframe will be determined based on the final position of the window frame and the wall thickness, all the non-removable shimming blocks will be glued to the main structure.
The subframe will be equipped with an outside wooden plank adequately sized to act as a seat for the subsequent installation of the window frame.
