Metrac PP32 can be used in a wall application as well as roof. The orientation and colour face is entirely down to you, however typically the wide pan is facing outwards to give a less industrial aesthetic and also to increase the insulation zone behind by 32mm to maximise thermal performance.
Due to a lesser wind and imposed load on walls the product gauge is usually reduced to 0.5mm when cladding in steel. If aluminium, 0.9mm is used on both walls and roofs to provide adequate impact resistance.
Max panel length:
Panel length limited by practical handling considerations – typically up to 10m.
