Thermal insulation

The Thermal insulation value for a material is its ability to resist the flow of heat across it. The measure of this heat flow rate is known as a materials K value and the lower this value the higher the products thermal efficiency.

The table below shows that broadly speaking the K value for foamed concrete lies between 0.08w/mk at the lower densities and 0.62w/mk at the higher densities.

What is Foamed Concrete?

Foamed concrete is a highly air entrained sand cement or cement only slurry with greater than 20% air by volume. The air is created by the introduction of a preformed foam manufactured using Propump Engineering’s custom foaming agent (Propump 26), encapsulating bubbles of 0.3-1.5mm diameter.

The material is a lightweight, free-flowing, self-compacting, and highly insulating material. It exhibits good load bearing capacity and resistance to freeze thaw exposure. It is an extremely versatile product, which will flow through small enclosed voids such as sewers and yet when set can be tooled to provide access for services.
