Roof
foam 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 foam 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. Roof foam insulation does not particularly address ventilation or sound
proofing issues. Roofing insulation simply refers to the insulating materials
being used to slow heat loss. The effectiveness of roof foam insulation is
usually evaluated by its R-value, but this does not take into account
construction or local environment factors. Roof foam insulation is easy to
apply. Roof foam insulation is sprayed onto or into the underside of the roof
within the attic/loft space, and dries to rigid foam. The application of this
process is normally completed within two days.
