9. What is Expanded Polystyrene (EPS)

10. WHAT IS EXPANDED POLYSTYRENE (EPS)
EPS is approximately 98% air and 2% plastic
Base material is styrene monomer, a by-product of oil refining
Styrene also occurs naturally in many foods
Polystyrene is produced when the styrene monomer is polymerised
Due to its technical properties EPS can be used in a wide range of
applications
A highly versatile lightweight, cellular plastic
98% AIR 2% PLASTIC

25. Expanded Polystyrene v Other Insulations

26. EPS v Polyisocyanurate (PIR)
Economy - up to 50% cheaper
Performance - low Lambda
Supply - short lead times
EPS is the Perfect Alternative
Thickness Comparison
100mm PIR = 135mm PlusTherm EPS
150mm PIR = 205mm PlusTherm EPS
50mm PIR = 70mm PlusTherm EPS

27. EPS v Mineral Wool
Mineral Wool Disadvantages
Skin irritant due to fibres
Dust mask / PPE required for installation
EPS is the Perfect Alternative
Thickness Comparison
150mm Mineral Wool = 135mm PlusTherm EPS
200mm Mineral Wool = 175mm PlusTherm EPS
100mm Mineral Wool = 90mm PlusTherm EPS
Up to 30% more expensive than EPS
Absorbs water adding to weight and decreasing thermal performance
Low impact resistance therefore compresses easily
Requires careful storage to prevent moisture ingress

28. EPS v Phenolic
Phenolic Disadvantages
Can cause staining on surfaces
Up to 40% more expensive than EPS
EPS is the Perfect Alternative
Thickness Comparison
100mm Phenolic = 165mm PlusTherm EPS
150mm Phenolic = 250mm PlusTherm EPS
50mm Phenolic = 85mm PlusTherm EPS
Long lead times
Long term thermal performance reduction
Absorbs water adding to weight and decreasing thermal performance
If it gets wet an acid is formed which can corrode metal components
Boards shrink if they get wet and dry out

29. EPS v Extruded Polystyrene
XPS Disadvantages
Up to 50% more expensive than EPS
Boards are heavy to handle
EPS is the Perfect Alternative
Thickness Comparison
100mm XPS = 90mm PlusTherm EPS
