High-performance extruded polystyrene insulation boards for thermal insulation in demanding conditions; designed for groundwork, floors and vertical installations. Check features and price before you buy from SityPro.
Key Benefits
- Excellent thermal insulation due to closed-cell extruded structure
- Low water absorption for long-term performance
- High mechanical load-bearing strength
- Unaffected by weather, resistant to cold and heat
- Durable and easy to handle with common tools
- Does not emit harmful particles or gases; 100% recyclable
Applications
Suitable for a range of insulation applications where moisture resistance and strength are required; see full application guidance before installation.
- Horizontal insulation on compacted ground or under screed
- On reinforced concrete intermediate floors
- Vertical insulation fixed to structures (glued or mechanically fastened)
- Perimeter and foundation insulation
- Floor insulation beneath concrete slabs
What to Consider When Choosing
- Stagger joints — do not align seams of upper and lower rows
- Install horizontal layers on a firm, flat surface (compacted ground, reinforced concrete)
- Vertical boards must be glued or mechanically fixed to the structure
- Use suitable adhesives (solvent-free cold bitumen, PU or cement-based) and follow the adhesive manufacturer’s guidance for polystyrene
- Improve adhesion by mechanically roughening the surface or use grooved Finnfoam XX boards
- Verify useful dimensions (585 × 1185 mm) and thickness (50 mm) for project planning
