Thermal Insulation

Thermal insulation is the reduction of heat transfer (the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.

Perlite Roof Insulation

Perlite is a quality product used as roof insulation material under waterproofing systems having the properties of fire resistant, light weight, thermal insulation, high strength, noise absorption, non-toxic, inorganic, non-combustion, quick installation and economical .

The perlite ore is crushed, dried and graded. When perlite ore grains are abruptly subjected to immediate heat near to their softening point 930 o C the combined water rapidly vaporize causing them to expand 4 to 20 times their volume. The expansion process creates countless air voids in the grains which account for the lightweight insulating properties of Expanded Perlite. Because of these unique properties, perlite is used in the manufacture of masonry wall insulation, under floor insulation and roof deck insulation etc.

As thermal insulation, expanded perlite gives excellent results at temperatures ranging from very low to very high. Perlite concrete can be made with dry density of 340kg/m3. The lower the density the higher the insulating value.

The perlite can also be used in areas where the foam concrete operations are not practicable. Also covering perlite by sand cement slurry topping, provides a solid base for roofing system. It can also be laid to high slopes more than 1% which is a limitation with foam concrete.

Polystyrene Roof Insulation

The great success of the Inverted roof concept is that it protects the membrane from all stress like temperature, thermal cycling and high Ultra-Violet radiation from Sun by having the Thermal Insulation over the membrane rather than under it as in the case of conventional roofs.

ASE are very well versed with polystyrene roof insulations and are applying these insulations on most of there projects.

ASE has good technical know-how to install both extruded polystyrene as well as expanded polystyrene in conjunction with different roofing systems.

ASE has a special Hi-Build Roofing System to use expanded polystyrene roof insulation with guaranteed protection.
