One of the most important aspects of roofing is energy efficiency. By choosing the right material, you can reduce the amount of heat that enters and exits your home. This means you spend less on your energy bills while still enjoying a comfortable interior environment.
That’s where the Solar Reflectance Index (SRI) comes in handy. Learn what it is and how you can use it to get a “cool” roof.
What Is the SRI Used For?
The Solar Reflectance Index is the measure of the roof’s ability to reject solar heat. A unit of measurement designed to combine both reflectivity and emissivity of materials for both residential and commercial roofing, the SRI is a useful guide for homeowners and roof buyers to the kind of material they should to invest in. It is rated from 0 to 100, with 0 being the most likely to absorb heat and 100 being the least likely.
What Are the Criteria for SRI?
As mentioned before, SRI uses both the reflectivity and emissivity of roofs to determine its rating. It combines all possible thermal properties of a roof into a comprehensive rating.
This applies not only to the roof itself but also to the coating of a roof. That’s why metal roofs can have higher ratings than those made of asphalt or wood.
How Does It Help My Home?
When you choose materials and coatings that give you an SRI rating nearer to 100, you will experience the benefits immediately. Your system will keep you cool even on the hottest summer day. It will absorb as little heat from the sunlight as possible and make sure that none of the heat goes into your home. This means you can save money on your energy costs while enjoying a cooler home.
