Standard or dark roofs can reach temperatures of 150 f or more in the summer sun.
Cool roof technology.
A cool roof transfers less heat to the building below so the building stays cooler and uses less energy for air conditioning.
Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles.
Cool roofs is a green building technology that is especially suited to the climate of india.
It is a relatively cheap option with substantial benefits.
A cool roof is a roof that reflects more sunlight and absorbs less heat than a standard roof lowering roof temperature and releasing less heat into the environment.
Cool roofs is a green building technology that is especially suited to the climate of the india.
A cool roof under the same conditions could stay more than 50 f cooler and save energy and money by using less air conditioning.
Roof temperature is rated via solar reflectance and thermal emittance with ratings ranging between 0 and 1.
Reduced air pollution and greenhouse gas emissions.
Historically cool roofs have been either white.
One of the most popular technologies the industry has developed is cool roof technology.
It is a relatively cheap option with substantial benefits.
With all the focus on green building these days the market is heating up with interest in cool roof technology.
This article throws light on cool roof technology with a special emphasis on its suitability in the indian context.
Design design and inspire view all.
Cool roof requirements vary by region but generally are based on solar reflectance and.
Total protection is more than shingle deep.
Whether these new roofs use new materials new construction techniques or both the ultimate goal is to maintain or improve a building s comfort at a substantially lower.
This results in lower absorption of solar heat and a cooler roof.

A cool roof prevents heat absorption by reflecting the sun s heat and then emitting its radiation back into the atmosphere.
A cool roof is a roofing system that delivers higher solar reflectance the ability to reflect the visible infrared and ultraviolet wavelengths of the sun reducing heat transfer to the building and higher thermal emittance the ability to radiate absorbed or non reflected solar energy than standard designed roofing products.
Parts of a roof total protection roofing system.
By lowering energy use cool roofs decrease the production of associated air pollution and greenhouse gas emissions.
What constitutes a cool roof.
Whereas darker traditional roofing materials absorb sunlight the reflective surfaces of a cool roof reflect it away.
Cool roofs are designed to reflect more energy and heat than traditional roofs.
Yet you may not be familiar with what exactly the term means so let s give you a quick primer on cool roof technology with a special emphasis on its suitability in the indian context.
As in golf the higher the rating the lower the.
