High Albedo Roof Coating

In the morning and in the late afternoon the high albedo materials were as cool as the air itself.

High albedo roof coating.

High albedo paint is an elastic ready to use roof coating. By lowering the absorption of solar energy high albedo coatings reduce building surface temperatures and heat transfer to the building interior. Since it works on the principle of continuous rejection of uv and ir rays the roof itself is not getting heated up. 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.

Measures cr 1 and cr 2 examine the impacts of applying such a coating over a light gravel covered built up roof. In this view those coatings are usually applied over flat and low sloped roofs in general in order to avoid summer overheating. 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. 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.

This high sri paint acts as heat reducing paint which can be applied as cool roof coating having single objective of roof insulation. In contrast to conventional roofs these kind are specifically designed to reduce internal building temperature by reflecting the sun s uv rays. High albedo coatings as previously mentioned are able to limit the increase of surface temperature of a roof in opposition to a high absorptive finishing. Substitute reflective marble chips or gray slag for dark gravel in a flood coat of asphalt.

High albedo roof coatings can be used to reduce building air conditioning use and if implemented at large scale might reduce summer urban temperatures. Apply a cool coating directly on top of a dark asphaltic emulsion coating. Albedo reflective roof coatings and assesses the use of high albedo however is likely to decrease if the initial albedo is high building materials for cooling energy and peak power sav because of surface accumulations and material degradation.

This results in the dark colored pavement surface while achieving much higher albedo. Use reflective mineral granules or a factory applied coating rather than a dark coating on a mineral surfaced sheet. One of the more recent advancements in the field of green commercial construction are what are known as cool or albedo roofs.
