Inverted roofs are becoming a popular alternative to conventional roofs as their benefits become increasingly obvious. One of the most popular methods of reducing heat is roof greening. Which has just found its way onto the Pakistan’s market with highly commendable results. In addition, to the various other methods used in Pakistan to reduce the heat on the roof. Many people use colored shingles, inlaid imported marble and other materials to spray roofs.
Unlike conventional roofs, where we place insulation in a protective membrane. Inverted roofs are designed with a membrane that is applied like a liquid. The insulation can remain unaffected by frost – dew cycle, resists water absorption. Also provides excellent thermal performance. And also protects against UV rays or mechanical damage.
Invert roofs also acts as protective membranes. We lay the insulation panel loosely onto the membrane. And then weighed down with paving slabs (for green roofs) and covered with bitumen or asphalt. We apply an inexpensive mineral as a protective layer with bright – colored marble. More layers on the roof further reduces heat. But not as much as a single layer of insulation can cause heat loss. It also contributes to creating a more comfortable indoor climate. And also plays a key role in extending the service life of the roof and its materials.
It has been shown that such coatings are applicable to clay and clay tile roofs. In order to reduce the cooling load and at the same time increase the aesthetic value of the building. Our recent study found that increased roof reflection reduces cooling performance in air-conditioned buildings by 18% to 93%. This indicates that bright coloured roofs have 30% less heat gain (-18%) compared to dark roofs. And that the use of air conditioning and heating in buildings reduces up to 20%. Roof Treatment Services provides one of the best services of basement waterproofing all over the Pakistan. That includes Karachi, Lahore, Peshawar, Hyderabad, Sukkur, Balochistan and Islamabad.
