HEAT GUARD range has proven the most suitable radiant heat, under deck insulation for the tropics since past 20 years. Multiple benefits, highly durable, low cost & easy application for both new & old buildings, very low pay-back period – huge savings in energy costs & absolutely hygienic. Various project references – includes major Airports, landmark constructions, commercial buildings, theatres, shopping malls, residential buildings, factories, food units, animal husbandry units etc., successfully completed all over the world including India. Use of radiant heat barriers is statutory item for building construction in most developed nations.
