Roof Insulation

Roof 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. Roof insulation is an important factor to achieving thermal comfort for the buildings occupants, and roof insulation reduces unwanted heat loss, and reduces the energy requirements of cooling and heating systems. Roof insulation does not particularly address ventilation or sound proofing issues. Roof insulation simply refers to the insulating materials being used to slow heat loss. Materials commonly employed in roof 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. Roof insulation is normally easy to apply, as most types of the roof insulating material are simply laid down.
