Roofing Insulation

Roofing insulation is used in buildings, and refers to the application of thermal insulated materials, which are applied using various methods, into a roof space, to prevent heat loss. Roofing insulation is an important factor to achieving thermal comfort for the buildings occupants, and roofing insulation reduces unwanted heat loss, and reduces the energy requirements of cooling and heating systems. Roofing insulation does not particularly address ventilation or sound proofing issues. Roofing insulation simply refers to the insulating materials being used to slow heat loss. Materials commonly employed in roofing insulation are, cellulose, rock wool, vermiculite, polystyrene, fibreglass and urethane foam. The effectiveness of roof insulation is usually evaluated by its R-value, but this does not take into account construction or local environment factors. Roofing insulation is normally easy to apply, as most types of roofing insulation are simply laid down.
