XPS insulation board

XPS Insulation Board (Extruded Polystyrene Insulation Board) is a rigid thermal insulation material made by polystyrene resin extrusion process. It features a closed-cell foam structure with high density, excellent thermal insulation and waterproof performance, widely used in building roof, wall and ground insulation systems.

Role in Solar Tile Installation

•  Installed under the solar tile system to provide efficient thermal insulation for the roof, reducing indoor temperature fluctuation and energy consumption.

•  Form a stable and flat base layer to ensure the solar tile mounting structure is more stable and uniform.

•  Effectively block moisture and water vapor penetration, protecting the roof structure and extending the service life of the entire roofing system.

•  Reduce heat conduction between the roof surface and indoor space, improving the overall energy-saving effect of the building.

•  Resist compression and wind-snow load, providing auxiliary support for the solar tile system.

Key Performance Features

•  Excellent thermal insulation performance: Low thermal conductivity, stable long-term insulation effect.

•  High compressive strength: Not easy to deform under long-term load, suitable for roof bearing.

•  Low water absorption & good waterproofness: Closed-cell structure effectively resists moisture and rain.

•  Strong corrosion & aging resistance: Stable performance under UV, high and low temperature, freeze-thaw cycles.

•  Light weight & easy construction: Easy to cut, lay and install without complex tools.

•  Good dimensional stability: Small deformation under temperature changes, durable and reliable.
