Question: 1 / 400

What is a primary function of rigid foam insulation in brick walls?

To increase the weight of the structure

To provide structural support

To enhance thermal efficiency

Rigid foam insulation plays a crucial role in enhancing thermal efficiency within brick walls. Its primary function is to create a barrier that reduces heat transfer between the interior and exterior environments. This insulation material is characterized by its low thermal conductivity, meaning it effectively resists the flow of heat. By installing rigid foam insulation, the overall energy efficiency of a building is improved, leading to reduced heating and cooling costs and more consistent interior temperatures.

While increasing the weight of a structure, providing structural support, or improving moisture retention may manifest in specific building contexts with other materials, these functions are not inherent to rigid foam insulation itself. Instead, its primary utility lies in its capacity to bolster the thermal performance of wall assemblies, making it a vital component in energy-efficient construction.
