Title 24 Roof Coating

Roofing products with high solar reflectance and thermal emittance are referred to as cool roof which is the outer layer or exterior surface of a roof.

Title 24 roof coating.

The title 24 standards do not require a cool roof on a residence when energy compliance is achieved using the performance method. It reduces surface temperature and penetration of the sun s rays to the roof surface which helps reduce roof and interior temperatures as well as energy costs. National coatings specializes in manufacturing many highly reflective roof coating products. Henry 280dc white roof coating title 24 is a premium water based acrylic latex coating.
