XPS Insulation Board
Premium extruded polystyrene board for high-performance thermal insulation, moisture resistance, and long-term durability across roofs, walls, and slabs.
Thermal performance with moisture protection
IBS XPS Insulation Board is engineered to deliver superior compressive strength, stable R-values, and resistance to water absorption. It keeps interiors cooler during summer and helps reduce energy use in hot climates.
Key advantages
- High compressive strength for roof loading and traffic
- Low water absorption and long-term thermal stability
- Excellent vapor resistance and insulation continuity
- Easy to cut, install, and seal on roof assemblies
Where XPS Board works best
Use it in finished roof gardens, inverted roofs, balconies, terraces, and external walls to create a stable thermal envelope with reliable moisture control.
Roof insulation
Protect roof slabs against heat gain while maintaining compressive strength for foot traffic and roof finishes.
Wall systems
Improve external wall insulation and reduce thermal bridge risk with rigid board layers.
Basement slabs
Provide a continuous insulation layer under slabs with low water absorption and long-term stability.
Technical features
Low thermal conductivity reduces heat transfer and improves indoor comfort.
Highly closed-cell structure prevents water absorption and maintains insulation value.
Resists compressive deformation, ensuring long service life under loads.
Applications and installation
- Flat and pitched roof assemblies
- Green roof systems and rooftop terraces
- External insulated wall cladding
- Basement floor insulation and internal slabs

Frequently asked questions
Can XPS board be used under a waterproofing membrane?
Yes. XPS is ideal beneath membranes because it stays dry and stabilizes the roof assembly.
How much temperature reduction can it deliver?
Installed correctly, XPS can reduce roof surface heat gain significantly and help lower cooling loads.
Is the board suitable for high-foot-traffic roofs?
Yes. With the right thickness and overlay, XPS supports foot traffic and roof finishing materials.
