Blocks U-Value calculator

This easy-to-use interactive tool is designed to help calculate the thermal performance of varying combinations of insulation and blocks, including aircrete and aggregate blocks.

The calculator takes into account wall configuration, internal and external finishes, insulations, as well as internal and external masonry leaf options, to give a more detailed assessment of the thermal performance of the wall proposed. Furthermore, images and descriptions for each aspect of the wall’s build provide extra clarity, with a final representation of the wall’s structure shown at the end of the process.
