Application

• Thermal insulation for areas subject to low mechanical loads.
• Insulation of walls and ceilings from below in Joint-less Warming Systems (BSO), such as those using light-wet methods.
• Insulation for walls with cladding, ventilated by air gaps.
• Thermal insulation of crowns under plaster, as well as lintels and door frames.
• Insulation for ceilings made of reinforced concrete, serving as lost formwork.
• Insulation for steep roofs, placed under the supporting structure.
• Foamed 75mm polystyrene boards EPS70 should not be used in direct contact with substances that degrade polystyrene, such as organic solvents (e.g., propane, benzene, turpentine).

Characteristics

• Expanded polystyrene (EPS) resists moisture and works well with most building materials, except those containing solvents.
• 75mm EPS remains rot-proof, resists bacteria, mould, and fungi, whilst being non-toxic, non-irritating, and odourless.
• 75mm EPS contains no CFCs or HCFCs; however, it is combustible when tested to BS476: Part 4 and will ignite when exposed to flame.
• Store the material in a covered location, shielded from direct sunlight and ground moisture.

Certification

75mm EPS70 foamed polystyrene boards meet Standard PN-EN 13163:2009 manufacturing requirements.
