When insulating floors, the thermal insulation panels should be laid on the slab and under the floor. It is important to know that the insulation panel can be subject to possible condensation of water vapour. It is, therefore, necessary to maintain the surface temperature of the floor as close as possible to that of the indoor air temperature. The thermal insulation panel must possess good hygrothermal properties and good mechanical performance. The waterproof bituminous membrane, which is useful in order to avoid humidity, becomes necessary in the presence of surface aquifers. The type of vapour barrier must be assessed in relation to the internal and environmental hygrometric conditions.
Once clean and leveled, the slab must be protected by a vapour barrier, on which the insulation panels* are fitted. The panels do not need mechanical fixings: they are to be placed dry mortarless on the underlying surface. It is advisable to always seal the joints with a cold self-adhesive band, in order to ensure the continuity of the vapour barrier.
In the isolation of the floor against the ground, when looking for a solution that offers a simple vapour screen (which merely, regulates the flow of vapor without completely blocking its passage), SUPERCEL PAPYRUS which have vapour permeable coatings is the best choice.
However should a vapor barrier be required, it is preferable to opt for a panel with air-tight coatings such as SUPERCEL ALUMEN.

In heated floors, to avoid the formation of cold areas, the insulation layer must be homogeneous and perfectly placed. With this type of flooring it is necessary to use insulation panels that are waterproof and vapour permeable, in order not to impair the performance of the heating system and at the same time avoid the formation of condensation and mildew. Moreover, the insulation panel should have excellent values: both in terms of thermal conductivity, so as to avoid heat dispersion, and in terms of mechanical resistance, because of the exposure to constant loads.
The panels are positioned and lined up against the underlying surface, covered by a waterproof membrane.
A sheet of polyethylene is used as
protection from the subsequent casting of the screed. On this protection layer the pipes of the heating system are laid and then buried by a layer of screed. Lastly, the finish chosen as flooring is placed.
In underfloor heating systems, SUPERCEL PAPYRUS panels are the best solution. Thanks to the superior coating in waterproof aluminium, they act as vapour barrier. Alternatively, SUPERCEL ALUMEN is a valid options.

This type of floor, which presents high-mechanical performance is made for civil or industrial low temperatures cold storage cells, where high resistance is required both in terms of static and dynamic loads. In fact it is always made up of a concrete structure that enables the drivethrough of trucks.
In this application, the insulation panels are placed on the clean and leveled slab, covering the entirety of the surface. In case of construction of a cold room, a waterproof membrane is first laid over the slab to form a vapour barrier.
Over the layer consisting of insulation panels, that do not require mechanical fixings, a separator layer is placed: the objective is to
protect the insulation from the cement that will be cast as reinforcement mesh. The reinforced concrete has the function of distributing the loads. A layer of asphalt completes the structure.The thermal insulation chosen for this application must have a good compressive strength and the ability to withstand low temperatures.
SUPERCEL BUILDING panels in addition to high insulation performance, offer good mechanical resistance to loads and are perfectly suited for this kind of application.
Among these, SUPERCEL ALUMENare the best choice beacause is finished with a air-tight coating that acts as a vapour barrier. SUPERCEL VITRUM panels are also suitable for this application.
