Innovative heat-dispersing clay bricks help keep homes naturally cool

A new innovative brick is paving the way towards more comfortable, affordable, and sustainable architectural solutions in hot climates. Colombian architects Miguel Niño and Johanna Navarro of Sumart Diseño y Arquitectura SAS designed BT - Bloque Termodisipador (HB - Heatsink Brick), a type of clay brick that helps keep buildings naturally cool through smart design. Made with an irregular shape, the brick’s angled and perforated form not only improves the building’s thermal comfort, but also helps reduce material waste and construction time.

In contrast to standard bricks, the BT – Bloque Termodisipador is five-sided and asymmetrical, with a large angled face that helps protect the brick from solar radiation. The bricks are perforated with a porous cellular structure to allow winds to pass through the bricks and dissipate stored heat.

“With traditional fired clay bricks, heat is transferred in one direction, due to the horizontal surfaces that make up the channels in the bricks, acting as thermal bridges that conduct the heat to the inside at a greater speed,” write the architects. “The horizontal surfaces of the BT – Bloque Termodisipador are interrupted by a series of smaller sub-channels, making it so the path of the heat is longer, and slowing and reducing its entrance inside.” The energy-efficient bricks also have the advantage of reducing noise by breaking up and reflecting sound waves.
