Roof Sheeting insulation is the provision of insulation in the roof space in order to prevent heat loss through the ceilings of the living spaces below. The method and type of insulation you use in the attic depends on whether the attic is to be used as a living space or not. This is typically done by fixing rigid insulation boards between the roof rafters. Boards must be cut to the correct width so that they fit snugly between the rafters. They can then be covered by plasterboard. Rafters aren't usually very deep, so to get the best performance you may have to insulate over them as well, using insulated plasterboard. If there isn't room to do this, make sure you use the highest performance insulation board. Walls in the roof space and around dormer windows should also be insulated. This is typically done with rigid insulation boards. Our Services Includes Metal Roofing,Industrial Roofing, MS Heavy Structure Work,etc.
