Complete waterproofing system for flat roofs
Made in France
- Flat roof floor system, made up of light concrete beams, light interjoists, thermal bridge breakers and a reinforced compression slab, poured 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 light concrete beams can reach up to 7,40m span
- EMX lightweight interjoists, made of synthetic material, are quick and easy to install
- Polystyrene dB Isoruptors, simple 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. »
