Reinforced and Tile Backer XPS Boards

Reinforced XPS Boards

Reinforced Extruded Polystyrene (XPS) boards are high-performance insulation panels designed to provide exceptional thermal resistance and structural strength. These boards are manufactured through a process of extruding polystyrene resin, resulting in a closed-cell, rigid foam with superior moisture resistance and durability. The reinforcement aspect typically involves the integration of a fibreglass mesh or other strengthening materials embedded within or laminated onto the board surface, enhancing its mechanical properties.

Reinforced XPS boards are widely used in construction applications where both insulation and load-bearing capacity are required. Their robust nature makes them suitable for use in floors, walls, and roofs, particularly in environments exposed to moisture or mechanical stress. The boards offer excellent compressive strength, making them ideal for underfloor heating systems, flat roofs, and external wall insulation systems (EWIS). Additionally, their resistance to water absorption ensures long-term performance without degradation.

Tile Backer XPS Boards

Tile Backer XPS boards are specialised insulation boards designed specifically to serve as a stable and moisture-resistant substrate for tiling applications. These boards combine the thermal insulation properties of XPS with a reinforced surface that provides a reliable base for the adhesion of tiles in wet and dry areas alike.

Typically, Tile Backer XPS boards feature a smooth or textured surface that promotes strong bonding with tile adhesives and grout. Their closed-cell structure prevents water ingress, making them particularly suitable for use in bathrooms, kitchens, swimming pools, and other areas prone to moisture exposure. The boards are lightweight yet sturdy, facilitating easy handling and installation while maintaining dimensional stability under load.

Key Characteristics:

• Reinforced XPS Boards
