Roof terrace floor system, composed of lightweight concrete beams, lightweight joists, thermal breaks and a reinforced compression slab, cast on site.
- A vapor barrier, thermal insulation and waterproofing complex must be installed on the upper face of the floor in order to complete the system.
- The range of lightweight concrete beams for the roof terrace floor can reach up to 7,40m in span.
- The Leader EMX lightweight interjoists of the roof terrace flooring system, made of synthetic material, are quick and easy to install.
- The polystyrene dB Isoruptors, easy to install, allow effective treatment of the thermal bridge at the connection with the parapet.
Prefabricated, this flat roof system integrates all the insulation above the concrete floor on the principle of a warm roof, on the terrace accessible or not, compatible with vegetation or a solar PV installation. It controls the dew point and treats thermal bridges. Composed of beams (LX12), interjoists (EMX) and transverse and longitudinal dB isoruptors, it is placed on the concrete slab with the pouring of a compression slab and the installation of waterproofing layers, without the need to lay a vapor barrier on the underside. Product under technical opinion.
“Terrawatt terrace roof flooring is efficient: treated thermal bridges, with unrivaled Psi values. Terrawatt roof terrace flooring is safe: the most efficient and safest solution for a condensation-free roof terrace flooring. The principle of the warm roof, with 100% of the insulation above the floor. Dew point controlled, risk of condensation eliminated. »
