Premium Cement Coated XPS300 Transition Boards for Underfloor Heating

Tackle tricky pipe routing with our robust cement-coated XPS300 transition boards — the professional solution for managing bunched or returning underfloor heating pipes in doorways, thresholds, and heavy-traffic zones. These specialized panels keep multiple UFH pipes neatly recessed, locked in place, and protected from lift, movement, or compression during and after installation.

Made from high-density XPS300 extruded polystyrene, the boards deliver excellent thermal insulation and compressive strength while the reinforced cement coating provides superior adhesion for tile adhesive, screed, or self-levelling compounds. This ensures a flat, durable finish and maintains insulation continuity across transitions.

Key Features & Benefits

• Secure Pipe Control — Designed to recess and firmly lock multiple underfloor heating pipes, preventing movement or damage in high-stress areas like doorways and thresholds.
• High Compressive Strength — 300 kPa XPS core withstands heavy foot traffic and loads without compromising pipe protection.
• Excellent Adhesion Surface — Reinforced cement coating bonds reliably with tile adhesives, thin screeds, and self-levellers for a seamless, long-lasting floor.
• Insulation Continuity — Maintains thermal performance across room transitions, reducing heat loss and improving overall UFH efficiency.
• Robust & Durable — Waterproof XPS base combined with cement facing creates a stable, professional-grade solution for residential and commercial floors.
• Easy Integration — Compatible with standard water underfloor heating systems; ideal where pipes return to the manifold or cross thresholds.

(Panel dimensions typically 1200 × 600mm or similar for compatibility with overlay systems—confirm exact size for your stock. Low-profile design minimizes added height while protecting pipes.)

Fix securely to level subfloors using appropriate adhesive or mechanical fixings as needed. Lay in alignment with main overlay boards for a flush transition.

Important: Due to product fragility (common with cement-coated XPS), orders are shipped by pallet for safe delivery.

Why Choose XPS300 Transition Boards?

• Prevents common installation issues like pipe lift or bunching in doorways and high-traffic zones.
• Provides a strong, adhesive-friendly surface for direct finishes (tiles, stone, screed).
• Ensures even heat distribution and energy efficiency by protecting and insulating pipework.
• Delivers a neat, professional result with minimal additional height or disruption.
• Suitable for both new installations and upgrades over concrete, screed, or timber subfloors.

These cement-coated XPS transition boards offer peace of mind in demanding areas, combining insulation, strength, and pipe security for reliable underfloor heating performance.
