The Komfort LO15 Castellated Tray System provides a low-profile alternative to traditional wet screed underfloor heating solutions, ideal for applications where minimizing build-up height is essential.

This lightweight, egg crate-style tray supports 12mm pipework and allows for self-levelling compound depths as shallow as 15mm, covering just over the tray. Its compact profile design makes it particularly suitable for renovation and retrofit projects, especially when working over insulated subfloors.

Manufactured from durable, rigid recycled high-impact polystyrene, the tray features a thermoformed, perforated structure. The base is pre-coated with a pressure-sensitive adhesive, facilitating easy bonding to mineral substrates like concrete or screed without the need for additional adhesives or fasteners. A protective silicone liner covers the adhesive until installation.

Built-in edge connections enable fast, precise panel alignment.

Perforations in the tray enable self-levelling screeds to bond directly through the mat to the subfloor, ensuring a solid, integrated finish. For best results, ensure the substrate is level, clean, and thermally insulated, and that the primer used is suitable for the specific floor surface.

Whether for small residential upgrades or large commercial refurbishments, this low-profile wet screed system offers an efficient, high-performance underfloor heating solution that minimizes build height and simplifies installation.
