ThermRite 18mm Routed Dry Screed Overlay Board with Turns

ThermRite High Performance Routed Dry Screed Overlay Cement Board with Turns

Description

The ThermRite Routed Dry Screed Overlay Board with Turns is a premium, high strength, grooved cement board specially designed for underfloor heating systems. Featuring integrated radius turns and straight runs on each panel, this board eliminates the need for separate turning panels, simplifying pipe installation.

With 4 grooves spaced at 150mm centres to securely hold 12mm pipe, it is engineered for superior heat transfer, low thermal resistance, and rapid heat response. The 18mm thick panel combines low profile design with high impact resistance and stable thermal expansion characteristics, allowing direct tiling without screeding.

What’s Included

• 25 x Routed cement boards with integral radius turns
• Panel size: 1200mm x 600mm
• Board thickness: 18mm

Key Features

• Integrated “lightbulb” radius turns at one end of the board, no turning boards needed
• 4 grooves at 150mm pipe centres for secure 12mm pipe positioning
• High thermal conductivity of 0.40 W/m·K and very low thermal resistance (0.045 m²·K/W)
• Low thermal expansion assures dimensional stability and prevents warping
• Only 18mm thick, enabling minimal floor build-up
• Does not contract or expand like chipboard when exposed to moisture
• High impact resistance provides durability underfoot and during screeding
