Premium Inverted Roof Insulation
|Our new range of Premium Inverted Roof Insulation is KIWA-certified and is available in a wide range of densities to meet the specified compression performance for applications from light traffic maintenance roofs to car parks and podiums.
An inverted roof construction places thermal insulation above the waterproof layer. This maintains the waterproof membrane at an even temperature and protects it from the damaging effects of UV radiation or the effects of the weather. The specified thermal performance of the inverted roof is achieved through the roof design and the thickness of the insulation used.
BEWI supplies insulation boards in a range of grades suitable for all flat roof applications.
Premium Inverted Roof Insulation boards in 200, 300 and 200+ grades have adequate resistance to the loads associated with light maintenance traffic on roofs, and to pedestrian foot traffic on balconies and roof terraces.
Premium Inverted Roof insulation in 500 and 600 grade meets higher loading requirements in applications such car parks and podiums.
Where paving slabs are to be placed over the insulation on spacer pads the point loads should be calculated to an equivalent uniformly distributed load (See datasheet for example).
