Glasswool

It consists of thin strands of glass arranged into a spongy texture.

Density 16 to 45 kg/m³

Thermal Conductivity: 0.04 W/mK

Polyurethane foam

This is a foam manufactured by reaction of two chemicals: polyol and isocyanate. During reaction, it generates carbon dioxide and expands 16 times to foam a very light insulation material that is equally rigid.

Density 30 kg/m³

Thermal Conductivity: 0.02 W/mK

Foam Concrete

Foam concrete is created by inclusion of a multitude of micro air bubbles in a cement based mixture mixing foaming Chemical with water and compressed air, generating foam therefrom.

Density 900-1200 kg/m³

Thermal Conductivity: 0.46 W/mK

Rockwool

This consists of interwoven fibers of mineral or artifical minerals or rock made by spinning molten rock at high speed.

Density 75 kg/m³

Thermal Conductivity: 0.03 W/mK

Expanded Polystyrene

Made by expanding polystyrene beads.

Density 20 kg/m³

Thermal Conductivity: 0.03 W/mK
