Has anyone had any experience of sprayed polyurathane foam insulation in buildings? I need to insulate a building (roof & walls) that will be my workshop. Roof is brand new fibre reinforced corrugated cement, walls are cement block to waist height then timber studding above. I had planned a suspended ceiling with rockwool on top, but I have headroom constraints that make the sprayed polyurathane look more promising. Walls could still be rockwool as it will be faced with 18mm boarding.
