AmbiLowBoard (SRB) Underfloor Heating System Overview
AmbiLowBoard (SRB) is a grooved cement board system, part of our low-profile range, ideal for retrofit scenarios. This system is designed for hard floor finishes such as tiles and wood flooring, which can be laid directly on top of the installed system. The boards are supplied in two pre-routed panels – straight boards and return panels, depending on the configuration of the pipework pattern.
The cementitious nature of the board gives it a low thermal resistance, which allows for a good and even spread of heat through the floor. The AmbiLowBoard (SRB) system must be laid on a flat, level and solid base, in order to give a consistent surface on which to lay floor coverings.
Note that floor finishes such as carpet and vinyl cannot be laid directly onto this system for point-loading reasons – in this scenario an additional layer (normally a 6 mm plywood) needs to be laid over the system before the floor finish is laid. We recommend bonding it down, rather than mechanically fixing, to avoid damage to the pipework.
