Underdeck insulation in metal roofs is necessary as metal roofs are known for their high thermal conductivity. It is a common knowledge that metal roofs account for nearly 40% to 50% of total heat gain in the building. In metal structures (PEB structures) in hot and dry climates, roof gets heated up very fast and once this happens heat gets spread into the entire building as there is no other escape route for it. So in hot and dry climates it is always advisable and sensible to insulate the metal roof.
Underdeck insulation in metal roofs has many benefits and the most important one being savings in energy that is spent on cooling inner atmosphere. It offers better climate conditions and inner atmosphere at times of harsh summer.
There are various types of underdeck insulation materials like cellulose filled insulation, structured insulation panels, polyethylene air bubble insulation, glass wool insulation, polystyrene insulation, rock wool insulation, natural wool insulation, foil thermal insulation and polyurethane foam insulation.
INSUreflector offered by Supreme is made of polyethylene air bubble film (ABF) laminated with aluminum foil on one or both sides which can be used as under deck insulation material.
Thin reflective foil of INSUreflector having low emissivity and high reflectivity when installed with an air space restricts the transfer of far infra-red radiation making it an ideal material to be used for underdeck application. The bright surface of the aluminum foil reflects 96 to 99 per cent infra-red radiation received by the surface of a heated slate roof and make inner atmosphere more liveable. It protects the building from undesirable heat gain. In harsh thermal conditions it increases the inner comfort level and decrease the effect of environment.
By installing INSUreflector in underdeck insulation you can protect heat from entering inside the house which in turn will increase the cooling efficiency of air conditioner. Also it will result in decreased cooling time for the A/C. This will ultimately result in saving in energy consumption for cooling devices. INSUreflector also provides resistance against vapour and moisture.
Thus, INSUreflector is the most effective underdeck insulation material which can help to keep your home cooler and at the same time bringing substantial savings in energy consumption.
