Thermal Mass Explained

There is a dispensation in the Building Code, for concrete and masonry R-values, because of benefits of the thermal mass of the concrete.

Regulating Internal Temperature

By taking advantage of this thermal mass, in combination with an appropriate level of roof insulation and double glazing, the Litecrete external walls regulate internal temperatures to provide a healthy and energy-efficient living environment throughout the year.

These benefits are achieved during winter as, when the sun is at its lowest angle, the Litecrete walls directly absorb the sun’s energy. As the sun goes down towards evening, the accumulated heat is gradually released back into the house to maintain a constant temperature.

During summer the reverse takes place. In combination with shading to prevent the high-angled sun from directly entering the house, the Litecrete walls absorb excess heat to balance the internal temperature. At night, opened windows purge the Litecrete walls of heat build-up, enabling them to cool and become ready to again absorb excess heat the following day.

Because Litecrete wall panels have built-in insulation they offer:

1. A more pleasant living environment in both winter and summer.
2. Half the heating requirements of an uninsulated home.
3. Reduced noise levels from outside sources.
4. A healthier environment with less risk of sickness.
5. Savings on heating and energy costs.
