Innovations in weathering tiles help lower temperatures

During construction, homeowners often find themselves confused when it comes to weathering courses. “A weathering course does help, traditionally, to reduce heat by some degrees by absorbing as well as reflecting heat and sunlight,” says N. Manikandan, architect, The Madras Design House. Today, the market has several new products that use traditional as well as scientific methods to reduce heat on the roof.

One such is Thermalcare, a new brand of weathering tiles that are also eco-friendly. “Our monolithic, cool roof tiles are manufactured from a proprietary blend of inorganic polymer-based binders. It is one of the best solutions for surface and inside room temperature reduction for new generation buildings,” says R. Sridharan, CEO, Thermalcare.

These tiles reportedly offer an environment-friendly solution that differs from conventional cool roof tiles, which are based on white cement. The white cement versions actually consume a lot of energy during production, say experts, and release a lot of carbon dioxide, which means they cannot qualify as green building material.

Sridharan, who has had the tiles tested by the Aviation Department, says that they contain no white cement or lime, are eco-friendly and lightweight (2.50 kg per sq. ft). “These new tiles offer protection from heat as well as water and their thermal performance is enhanced by carefully selected pigments.” One other advantage is that the tiles are made from homogeneous material with no layering. This means homeowners need not face bonding or peel-off issues later on.
