Clay bricks outperform lightweight materials

Back to all

Bricks are more energy efficient than lightweight materials.

Results from eight years of independent research conducted by the University Newcastle into energy efficient housing proves:

– Insulated cavity brick (full brick) construction performs the best for energy efficiency

– Lightweight construction was the worst performing building in all seasons

The following diagram illustrates how energy moves through your home, with cavity brick as the best performer in delaying the transfer of heat, then brick veneer, with lightweight materials ineffective.

Time it takes for heat to pass into your home (known as thermal lag)

A building material’s energy efficiency is measured on more than just the manufacturing process, it’s how it performs in a lived in home.

The energy consumption for spring conditions demonstrated that the insulated lightweight building required a greater amount of heating and cooling compared to insulated cavity brick*.
