Energy Efficiency of construction materials

The general applicability of the comparative superior thermal performance claims made by various lightweight walled Alternative Building System providers, that assume their walling systems’ higher insulation values [R‐values], relative to double skin clay brick walling, translate into superior thermal performance outcomes, is not supported by science and extensive thermal modelling of houses constructed with different wall types here in South Africa.

Graphs comparing the thermal comfort, energy efficiency and carbon footprint of various building materials including clay masonry brick, concrete block, cavity brick, leaf brick, Timber etc.
