Features
- Excellent thermal insulation with low thermal conductivity
- High compressive strength to withstand roof loads
- Closed-cell structure with very low water absorption
- Lightweight, easy to handle and install
- Resistant to rot and chemical attack
- Suitable for inverted roof systems (insulation above waterproof membrane)
- Available in square edge and shiplap edge profiles
Applications
- Inverted roof construction — insulation placed above waterproof membrane to protect it
- Traditional roof insulation — reducing heat transfer and cooling energy costs
- Green roof systems — providing base insulation beneath planting systems
- Terrace and podium insulation
Why Choose Sikatherm 830 XPS?
- Protects waterproofing: In inverted roof systems, insulation shields the membrane from temperature cycling, UV and mechanical damage
- Long-lasting insulation: Closed-cell structure ensures stable thermal performance long-term, unaffected by moisture
- High compressive strength: Withstands maintenance foot traffic and normal roof loads
- Compatible with Sika systems: Pairs with Sika liquid waterproofing membranes for complete roof waterproofing and insulation solutions
Packaging
Available in multiple thickness options, standard size boards.
Notes
- Must be used in conjunction with appropriate waterproof membrane
- Boards must be ballasted with gravel or concrete to resist wind uplift
- Avoid prolonged UV exposure (cover promptly after installation)
- Cut using saw blade or hot knife
- Not suitable for environments with organic solvents
