Building Insulation Does Not Increase Summer Overheating, Expert Says

Contrary to common belief, insulating a building does not cause it to overheat during the summer months. Hicham Johra, an engineer specializing in thermodynamics, clarified this misconception, explaining that heatwaves raise indoor temperatures but that insulation itself is not the cause of increased heat.

Johra addressed the misunderstandings that arise when rising temperatures inside buildings coincide with heatwaves. He emphasized that the principles of building thermodynamics dictate how heat interacts with structures, and proper insulation plays a role in maintaining stable indoor temperatures, regardless of external conditions.

The engineer's explanation aims to correct the notion that insulation traps heat excessively in the summer. While insulation is designed to resist heat transfer, its primary function is to keep heat out during warmer periods and in during colder periods, thereby contributing to energy efficiency and occupant comfort.
