My name is Anand Kumar from Roof Tech Inc. we are dealing with Heat Resistance Roof tiles. On installation, one will experience great comfort inside the building and in the event of using air conditioners less energy is consumed. Besides this, the INSULLA tiled terrace will enable one to use the terrace even before the Sun is about to set, which otherwise does not permit one to spend time comfortably as heat absorbed by the terrace floor keeps radiating heat even up to 9 pm during summer. Needless to say, the fast growing tribe of users in AP and TG are enjoying their summers! We do entire Building waterproofing . Please contact us for any queries . Regards, B.
