EPS70 Polystyrene Insulation Sheets
The term EPS70 relates to expanded polystyrene which has a compressive strength of 70 kPa.
EPS70 SDN insulation board is ideal for a variety of applications and can be produced in many shapes, strengths and sizes. Most common within the construction industry are the 2400 x 1200mm sheets which are mainly used for:
• Below concrete slab in domestic ground floor constructions
•Below floor screed
•Above concrete slab and concrete floors prior to the laying of floors
•Between joists to provide insulation for suspended timber ground floors
Properties and characteristics
The sheets comprise of expandable beads of polystyrene which are pre-foamed and fused together in a steam-heated mould under pressure.
•Thermal conductivity of 0.037 W/mK
•70 kPa compressive strength at 10% compression
• EPS does not contain CFC or HCFC but is a combustible when tested to BS476: Part 4 and will ignite with a flame
• EPS is rot proof, unaffected by bacteria, moulds or fungi and is non-toxic, non irritant and odourless. It also has no nutrient value to insects and vermin.
• EPS is moisture resistant, compatible with most building products except materials containing solvents
EPS is a combustible material but providing it is installed correctly in accordance with the manufacturers’ instructions, it will not prevent any undue fire hazard.
Other higher density grades of expanded polystyrene can be sourced on request. Other than EPS70, grades available are EPS100, EPS150, EPS200, EPS250, EPS300, EPS350, EPS400, EPS450 and EPS500. Some of these will have minimum order requirements. Please contact our helpful sales team on 01274 602367 if you would like to know more.
