Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam 98% of which contains air trapped within fine cells during manufacture. Unlike other building materials, where increase of strength means higher thermal conductivity and lower thermal performance, thermal qualities of expanded polystyrene improve with its strength (with its density).
Other advantages of expanded polystyrene insulation are: high resistance to biological corrosion, high resistance to the effects of moisture and water vapour (vapour permeability less than 2%).
EPS polystyrene is unaffected by insects and will not support the growth of fungi, moulds or bacteria. The material is non toxic and easy to cut and work with.
In terms of fire performance EPS polystyrene is flammable - however it does not contribute to the spread of flame and goes out after a short while. Expanded polystyrene should not be used in areas exposed to temperatures above 80°C. The material is not resistant to UV waves and if exposed to direct sun light for prolonged periods turns yellow losing its strength and begins to crumble.
The classification parameter of EPS polystyrene is its vertical compressive strength measured at 10 percent deformation or yield, e.g. EPS70 means expanded polystyrene with a compressive strength of not less than 70kPa.
Compressive strength of polystyrene is directly related to its flexural strength. Flexural strength of a material is defined as its ability to resist deformation (bending) under load and in case of EPS 70 polystyrene equals not less than 115kPa (minimum flexural strength of all EPS polystyrene products is 50kPa).
The mechanical strength of EPS polystyrene insulation determines its application that is why compressive stress has formed the basis for classification of polystyrene insulation products.
Polystyrene is manufactured in many forms and can be purchased as:
Insulation Cart offers EPS polystyrene insulation in a range of thickness to suit all applications. Our EPS boards come from recognised manufacturers - Kay-Metzeler, Jablite - all available with 1-2 days delivery within UK and 10-15 days within EEC.
