80mm Sundolitt XPS 300 Insulation Board

80mm Sundolitt XPS 300 (300kPa) Insulation Board is a rigid extruded polystyrene XPS insulation board engineered for high-moisture and demanding applications. This product excels in inverted roofs, flat and zero-pitch roof systems, green roof installations and ground-bearing projects where strength, durability and sustained thermal performance are paramount.

Built with a closed-cell XPS structure, 80mm Sundolitt XPS 300 delivers outstanding water resistance, moisture protection and frost resilience. Unlike conventional insulation materials, it resists rain, snow and sustained damp exposure, maintaining consistent thermal properties throughout its lifespan. This makes it particularly valuable for exposed or below-ground work.

Simple to handle and lightweight, 80mm Sundolitt XPS 300 insulation boards can be trimmed on-site using standard tools. The material maintains its stability and installation ease even during challenging weather, offering straightforward storage and application without performance loss.

Offering 300kPa compressive strength, Sundolitt XPS 300 provides a practical, durable option for applications demanding strong load-bearing properties. Common uses include solid flooring, foundation work, industrial floors, cold storage and chilled facilities, plus ground floor insulation for residential and commercial properties.
