Stone paving can also be laid on pedestals, calculating the necessary thickness, and on a heated floor, taking care to separate it from the support.

À l’extérieur, il est impératif de choisir la pierre en fonction du climat de la région et de gérer l’évacuation des eaux pluviales (pente, sous couche drainante, caniveau).

Attached Stone

The attached stone makes it possible to make wall coverings made up of stone slabs attached to a concrete or masonry support. A ventilated air space must be provided between the rear face of the plates and the insulation fixed to the support. The insulation thickness is commonly 15 cm and can be up to 28 cm.

Stone slabs, generally 3 cm thick, can have a surface area of up to 1 m² and one of their dimensions measuring up to 1.40 m, if the wind sizing calculations allow it. The fasteners are made up of solid stainless steel legs, adjustable in three directions. They are fixed to the support by metal plugs. Except in special cases, the number of fasteners is four per plate, sized to ensure the absorption of the weight and the forces of the wind. The plate / bracket connection is made by penetrating a stainless steel lug into a larger diameter hole in the edge of the plate.

Self-Supporting Walls

Self-supporting coverings are made of bondable wall stone or dressed stone laid in matching layers. They are 8 to 15 cm thick. Their stability, vis-à-vis the discharge, is ensured by connections fixed to the load-bearing wall. This type of design allows the walls to have to Appearance of massive stone while being relatively thin. but relatively thin. It also offers the advantage of allowing the installation of significant thermal insulation from the outside.

Massive Stone

Stone has always been used to construct buildings. Today it is possible to build in solid structural stone. The stone facades can contribute totally or partially to the structure of the building and can be imagined in association with other materials. Building in local massive stone is a responsible choice which allows to obtain low carbon construction. The use of solid stone will give a strong thermal inertia to your building, which will allow you to benefit from remarkable summer comfort.

With deposits of soft stones spread over all the territory, Polycor gives you access to a material of high environmental quality near you. Our sales team is at your disposal to build your massive stone project with you in compliance with DTU 20.1.

Our stones Saint-Vaast, Saint-Leu, Tervoux, Sireuil are particularly well suited for this type of project, while remaining within competitive budgets vis-à-vis traditional construction.

Polycor's Insulated Cladding

This cladding system uses a 20 mm natural stone panel bonded to a 60 to 100 mm thick high-density expanded polystyrene insulation. The thermal resistance (R) of the assembly varies from 1.58 to 2.63. The horizontal edges of the stone are grooved in the factory. The slabs are mounted on aluminum rails. These are pegged to the support through the insulation. The clothing benefits from a CSTB Technical Assessment.
