Solar Reflective Roof Coating

Due to this it prevents the roof from heating up during peak summer season thereby reduces the room temperature.

Solar reflective roof coating.

Solar reflective index sri is important to understand when selecting a highly reflective roof coating that will help lower energy cooling costs. That s changing radiation properties significantly in a simple operation. The black metal roof panel yielded a solar spectrum reflectance of 0 048 and an infrared emittance of 0 87. It is a ready to use roof coating when coated on the roofing materials reflects sunlight to a greater extent and prevents the roofing materials from getting heated up even in peak summer afternoons.

A single coat of lo mit on half of it yielded a solar spectrum reflectance of 0 829 and an infrared emittance of 0 20. Solar reflective coatings benefits most solar reflective roof coatings consist of a binder usually an organic polymer bitumen or inorganic polymer blended with pigments e g. Titanium dioxide or dispersed aluminum and other additives to produce a durable exterior coating. This product has the highest sri value of 124.

When cured it allows moisture vapor to vent or breathe out of underlying substrate. This is the reflectance in the visual part of the solar spectrum wavelengths of 400 to 700 nanometers. Gaf united coatings 5 gallon silicone reflective roof coating 20 year limited warranty item 1051026. Usually the visible reflectance is correlated with the solar reflectance but the two quantities are not equal.

Luminx is a solar reflective coating which has ability to reflects the maximum amount of uv and infra red rays. Excel coolcoat india s no 1 green certified heat reflective roof coating cool roof coating summer cool coating high albedo coating. The sri is a calculation method using solar reflectance and thermal emittance values to determine the roof s overall capacity to refuse solar heat. The coating itself has the maximum capacity to reflect the uv and infra red rays meaning it s capable of prevents the room itself from heating up during the summer season.

The attic under the roof. For pricing and availability. When compared to economy grade reflective roof coatings its elongation peel strength and solar reflectance values offer weather protection high solar reflectivity and superior longevity. Black jack elasto kool 700 5 gallon elastomeric reflective roof coating 7 year limited warranty item 139929.

For example a good white coating with a solar reflectance of 0 8 typically has a visible reflectance of about 0 9.
