Roof coatings and cool roof

Enhance elastomeric roof coatings and cool roof formulations and reduce costs with lightweight fillers

Elastomeric roof coatings help to protect and seal the underlying roofing material, stop and prevent leaks, and limit future weathering. Omya’s lightweight fillers improve the performance of roof coatings in terms of insulation, solar reflectance and weight.

Improve the comfort of your buildings with Omyasphere

Omyasphere is a lightweight filler which delivers better comfort for buildings by reducing the temperature in cool roof coatings.

The reflection of solar radiation, combined with lower thermal conductivity, positively impacts the indoor climate of buildings by reducing heat-build-up.

Higher solar reflectance

The solar reflectance index (SRI) is a key factor in buildings in warmer climates, where the main energy concern is cooling control.

Omya’s lightweight fillers positively influence the SRI of elastomeric roof coatings, which is based on measures of solar reflectance and thermal emittance.

Our lightweight fillers also improve the mechanical and weathering-related properties of roofing coatings, with a lower tendency to cracking leading to higher elongation.

Reduce the weight of your coatings

Omya lightweight fillers replace heavier materials such as mineral fillers, and therefore help to reduce the final weight of the coating. This has three major advantages:

less material to be carried and managed on site;
enhanced yield, which reduces the cost per square meter of coating applied;
and higher volume loading of trucks, which contributes to a lower carbon footprint.

Benefits

Weight reduction
Higher yield
Less material required on the job site
Higher solids by volume
Enhanced flexibility
Enhanced insulation properties
Reduced heat build-up

A more sustainable approach to roof coatings

The use of Omyasphere in roofing coatings lowers carbon emissions by decreasing the demand for cooling energy in buildings and by enabling higher volume loading of trucks for transport.
