The Retrofix XPS Transition Board is an essential tool for installers and DIY enthusiasts looking to simplify the layout of water underfloor heating systems in high-traffic or high-density areas. Designed for precision, these boards provide a dedicated routing system for 12mm pipes, significantly reducing installation complexity near manifolds and corridors; however, users should note that they require a level subfloor for optimal structural integrity and heat distribution.

No, these boards are specifically engineered for 12mm pipes. Using larger pipes will not fit the pre-formed channels.
While the boards are stable once the floor finish is applied, using a thin layer of floor adhesive or double-sided tape can prevent movement during the pipe installation phase.
Yes, but you must ensure there is a suitable subfloor or load-bearing layer between the board and the carpet to prevent damaging the pipe.
The XPS material is soft enough to be cut with a standard utility knife or a handsaw for clean edges.
These boards are designed for thermal management and pipe routing; they are not intended to bear structural loads without being covered by an appropriate floor finish.
Ensure the pipe is not under excessive tension; use small dabs of construction adhesive if necessary to secure the pipe in turns.
Check for debris under the board or high spots in the subfloor; clear the area or apply a leveling compound to the subfloor surface.
To install, ensure the subfloor is clean, dry, and level. If the subfloor is uneven, use a self-leveling compound before laying the boards to prevent future damage to the pipe or floor finish. The boards can be cut using a utility knife or a fine-tooth saw to fit around corners or obstacles. When placing pipes, press them firmly into the channels until they sit flush. Always handle the boards with care to prevent denting the XPS, as surface depressions can affect the finished floor height. Compatibility is limited strictly to 12mm diameter heating pipe; using larger pipe sizes will compromise the channel structural integrity.
