High Elbedo Roof

Most experienced field organization excellent customer satisfaction.

High elbedo roof.

A low albedo means a surface reflects a small amount of the incoming radiation and absorbs the rest. The cool roof rating council accepts test reports from approved testing laboratories and then compiles the information in an easily accessed database. The cool roof rating council is a not for profit organization that validates the reflective and emissive properties of cool roof products. For instance fresh snow reflects up to 95 of the incoming radiation.

This high sri paint acts as heat reducing paint which can be applied as cool roof coating having single objective of roof insulation. Its solar reflective properties make it one of the most suitable solar. Being a roof cooling and insulation paint it will act as a protective coating and best summer cool paint. Concrete s high albedo means more light is reflected and less heat is absorbed resulting in cooler communities.

And canada help keep good roofs and good buildings good for our customers through renovation restoration and maintenance as well as through new construction. As one would expect albedo roofs are formulated with special high eminence materials that keep project a high level of thermal energy back into the atmosphere. A sample cool roof this roof has a high albedo and reflects about 63 of the energy from sunlight. Reformulate or coat black membranes to make them reflective.

How they can be made cool. Built up roofs consist of a base sheet fabric reinforcement layers and usually a dark protective. On a sunny day a roof that strongly reflects sunlight can stay much cooler than a roof that absorbs sunlight. Coolroof heat reflective paint has been designed to give relief from roof heat as it is a high albedo paint having high sri value which makes it most suitable for roof insulation.

This concrete characteristic is particularly noteworthy in comparison to alternatives for paving and roofing. By preventing a majority of the heat from ever reaching the surface these roofs work to greatly reduce hvac cooling costs during the summer months. A high albedo means the surface reflects the majority of the radiation that hits it and absorbs the rest. Therefore fresh snow has a high albedo of 95.

On clear sunny days when the solar noon surface temperatures of conventional roofing materials were about 40 degrees c 72 degrees f warmer than air the surface temperature of high albedo coatings were only about 5degreesc warmer than air. In the morning and in the late afternoon the high albedo materials were as cool as the air itself.
