This essential carpentry in the field of both individual and collective residence renovation has 5 insulation chambers and 2 insulation joints.Ĭonsequently, it displays a Uw coefficient of 1.3 W/m².K in double glazing. The choice of the co-owners fell on a PVC carpentry adapting perfectly to the new architecture of the towers. It was therefore essential for the Lorenove Key Accounts teams to coordinate with the co-owners, the architect and the facade designer in order to adapt their schedules with individuals, to optimize the rental of the twin-mast nacelle set up for facade work, and for safety reasons, deploy the joinery according to the intervention schedule on the railings. This project, which lasted a total of 8 months, required the intervention of 2 to 3 installation teams each day, ie around ten people. In total, 1014 white PVC 5-chamber joinery fitted with a Renocity bay unit, including 110 tilt and turn, 334 2-leaf patio doors and 111 3-leaf patio doors were installed. In this case, the joinery was mounted on the different floors from the inside and was also installed from the inside. Thus, the Lorenove Key Accounts teams were able to coordinate with the other companies working on the site. In addition, the renovation of the joinery of these two towers was associated with the renovation of their facades.

The renovation of joinery in an occupied environment is a delicate intervention to which has been added the factor of great height for the supply of joinery which can then be done by the intervention of a lift or a crane. Renovating the carpentry of a high-rise building The architectural heritage of the buildings has also been upgraded with modern cladding. The work which began in 2021 aims to improve the energy label of buildings with the support of external thermal insulation in rock wool (carried out by the company Socateb) clad in aluminum cladding, PVC joinery equipped solar-powered shutters and low-pressure mechanical ventilation. Supported by the architectural firm "Architecture Pelegrin", this renovation also took up the challenge of restoring the architectural aspect of the fifty-year-old buildings. Designed in the 1970s, these towers house 206 apartments.

In 2014, the Parvis du Breuil condominium in Antony launched an ambitious project to renovate its two high-rise towers of 14 and 17 floors.
