Product FAQ
1. What are the primary uses of XPS foam boards for roofs?
XPS foam boards are used in flat, pitched, and green roof systems to provide thermal insulation, waterproofing, and structural stability.
2. How does the foam board ensure energy efficiency?
The board’s low thermal conductivity reduces heat transfer, minimizing energy loss and lowering heating and cooling costs.
3. Is the XPS foam board resistant to water?
Yes, its closed-cell structure and a water absorption rate of ≤1.0% make it highly resistant to water and moisture infiltration.
4. Can the dimensions of the foam board be customized?
Absolutely! The board is available in various lengths, widths, and thicknesses, and can be tailored to specific project requirements.
5. What is the lifespan of the XPS foam board?
The durable construction ensures the board retains its performance for decades under normal conditions.
6. How does compressive strength affect roof applications?
Higher compressive strength grades, such as X400 or X500, are ideal for heavy-duty applications where the roof must handle substantial loads or foot traffic.
