Everest Hi - Tech Roofing Sheets
Everest has 75 years of roofing experience, covering over 1 billion sq m of roofing. Everest Hi-Tech is a unique product manufactured in India using technology from Saint Gobain. It is a corrugated cement hi tech roofing sheet reinforced with a blend of strong factory-produced fibers including HIPP (High Impact Polypropylene). These imported fibers replace asbestos to give them high-impact resistance. Everest Hi Tech provides high sound insulation from rain and thermal insulation from heat, saving you huge costs of additional insulation.
Everest Hi-Tech meets all international norms of safety, environment and pollution control for building products. They can be used in all manufacturing and export oriented units, warehouses and modern factory sheds.
The Ultimate Choice
1. Non Asbestos
Everest Hi-Tech does not contain any asbestos and therefore conforms to international norms of multinational corporations and importers.
2. Low maintenance costs
Everest Hi-Tech has a high IMOR (work of fracture) i.e., energy absorbed in bending of sheet and impact resistance makes it more flexible, thus reducing damage during handling and exposure to dynamic loads.
Everest Hi-Tech does not corrode and is dimensionally stable (will not dent or deform). It is resistant to atmospheric (saline and acid rain environments) and chemical corrosion.
Everest Hi-Tech is significantly more economical than alternatives like colour coated metals, aluminum roofing, etc.
5. Weather Resistance
Everest Hi-Tech protects from weather elements i.e. sun (heat), rain and wind. Being cement-based, it gains strength with age and weathering.
Everest Hi-Tech is available in different colours using a specially developed and tropicalized pure acrylic paint on the top surface which ensures no algae or fungal growth. Additionally it has excellent UV resistance thus ensuring uniformity and longevity of the colour i.e. long-term aesthetics. The roofing sheets are also available in natural stone grey without acrylic paint.
7. Protection and comfort
Everest Hi-Tech is a better alternative in comparison to other roofing products.
- Sound insulation of 26 Decibels when tested in a critical frequency of 100-3150 Hz
- Low thermal conductivity of 0.22 W/mK, thus reducing heat buildup.
- Non combustible
- Excellent condensation control

Details of side Lap Corrugated Sheet
Everest Hi-Tech roofing sheets are available in a range of colours. These pre-painted sheets require low maintenance and resist the impact of weather, sunshine, UV rays, algae and chemical corrosion. The selection of colours appropriate to a building and its ambience involves the careful consideration of a wide range of criteria. These include the building's form and function, its location and surroundings, and most importantly, the viewer’s perception of colour. The look of the building can be enhanced aesthetically by using dual colour combination such as Green and White or White and Red. Everest Hi-Tech sheets are coated with the top of the line imported pure water based exterior acrylic coating. This coating provides resistance to ultra violet rays and any fungal or algae attack. The acrylic paint also provides added protection against many acids, alkalis and solvents normally found in the atmosphere and above all, provide long lasting aesthetics to the roofing sheets.
