Louineau

Louineau is a French company specializing in the design and manufacture of fastening, cladding and sealing systems for exterior joinery and the building envelope. Founded in 1981 and based in Luon, Vende, the company has established itself as a leading technical partner for professionals in construction, renovation and External Thermal Insulation (ETI). Louineaus core business is based on engineering and forming custom metal parts that ensure the connection and the thermal and mechanical fastening of joinery within the structural work. The company supports joiners, facade contractors, carpenters and builders through a dedicated engineering unit to define technical solutions adapted to the constraints of each jobsite. The product range is structured around several key families: monobloc metal subframes or kit versions (for perfect window integration in ETI), universal and reinforced fixing brackets, made-to-measure sheet-metal claddings (drip flashings, coping caps, bay surrounds) as well as expanding sealing tapes and air- and water-tightness membranes. Recognized for its approach of constant innovation, Louineau develops advanced digital tools (including load-calculation and bracket-selection configurators) and tests its products in line with the requirements of RE2020 and DTU 36.5. The company promotes 100% French manufacturing and guarantees the compliance of its solutions thanks to mechanical and AEV test protocols carried out in its own workshops.
