Solid Floor XPS Insulation Board 1200 x 600 x 25mm | 3 Grooves

ExpressDeck Bare Solid Floor Routed XPS Insulation Board – 25mm | 3 Grooves

The ExpressDeck Bare 25mm XPS insulation board is designed for solid floor underfloor heating installations where a bare (unfoiled) board is required. With three pre-routed channels, it provides a clean, accurate guide for UFH pipe layout in screed applications.

Key Benefits

• 3 pre-routed grooves – precisely positioned channels for fast, consistent pipe placement
• Bare board finish – ideal where foil facing is not required or where a separate reflective layer is used
• 25mm XPS core – enhanced thermal resistance reduces downward heat loss and improves system efficiency
• High compressive strength – withstands the weight of screed, tiles, and ongoing foot traffic
• Lightweight and easy to handle – 1200 x 600mm format is quick to cut and lay on site
• Compatible with standard 16mm UFH pipe and most wet underfloor heating systems
