The AmbiFloat 10 system can be used in existing floor constructions as well as new build applications. It requires a flat and leve lsolid sub floor for the insulation to fully support the floor finish on top. The insulation is pre-grooved to take the underfloor heating pipework and over laid with foil to assist the distribution of heat.
The installation involves covering the complete floor area with insulation and where necessary using battens to provide extra support to door thresholds or perimeter edging. The pipework is then laid into the grooves as per the installation drawings and taken back to the manifold to complete the circuit.
The system is then overlaid with a fully floating floor deck onto which your floor finish is applied. In the case of wooden floors, this can be laid directly on to the insulation to minimise height buildup and maximise the heating output. However, please note that you should always check with the wood flooring manufacturer before laying directly onto UFH systems. ,as some will insist that their products should not come in direct contact with the UFH pipework.
In this instance, you would need to lay an additional layer, such as a 6mm plywood.The reflective properties of the aluminium foil face mean that any heat is efficiently pushed up through the sub-floor layers for maximum heat output. The nature of the system means that it has a quicker response that a traditional (screed) UFH system.
