LowBoard 22

DS UFH 02.2

Introduction
LowBoard22 is a non structural, 22mm thick, tongue and grooved, moisture resistant chipboard underfloor heating panel that is floated or mechanically fixed over a flat and even timber or solid sub floor. The low panel height makes it suitable where there is not enough floor-to-ceiling height to install a conventional underfloor heating system. The panel has a multi-directional design for ease of installation. The universal panel is simply laid across the floor with no loop ends and straights to configure. The pipe pierces the foil diffuser as it is pressed into the channels, before a finished floor deck, 6mm flooring grade ply, MDF or similar is mechanically fixed over the LowBoard panels to complete the floor.

LowBoard22 is a non structural, 22mm thick, tongue and grooved, moisture resistant chipboard underfloor heating panel that is floated or mechanically fixed over a flat and even timber or solid sub floor. The low panel height makes it suitable where there is not enough floor-to-ceiling height to install a conventional underfloor heating system.

The panel has a multi-directional design for ease of installation. The universal panel is simply laid across the floor with no loop ends and straights to configure. The pipe pierces the foil diffuser as it is pressed into the channels, before a finished floor deck, 6mm flooring grade ply, MDF or similar is mechanically fixed over the LowBoard panels to complete the floor.

Specification
OMNIE LowBoard system using 12mm PE-RT pipe to DIN 4726. The 22mm LowBoard panels to be laid fully floating with all tongue and grooves fully glued to form a continuous layer over a flat & even sub-floor. Next a minimum of 6mm covering layer such as flooring grade ply is then mechanically fixed over the LowBoard panels. If timber or laminate is used there is no need for a covering layer on top of LowBoard. For tile & decorative vinyl floor finishes the LowBoard panels will require fixing to screed or a deflection free timber floor with all tongue and grooves fully glued with a minimum 6mm flooring grade ply or tile backerboard mechanically fixed over. Please refer to the Tilemaster Adhesives Ltd specification guide (IG UFH 23, see link below) or obtain specific conformation and guidance from floor finish installer or manufacturer/supplier. The system is to be designed, installed and commissioned to BS1264. ULTRALOW – This product has reduced build up compared to other available systems. For more information on UltraLow Technology see DS UFH 23 LAYFAST – Speed up installation time. This product uses our multi-directional pipe channel system. For more information see DS UFH 22 DRYSYSTEM – No wet trades required, designed for dry constructions. For more information see DS UFH 24 TILEOVER – Can be tiled over using our unique Tileover technology. For more information see IG UFH 23
