Terracotta to renovate a Parisian residence

The project involves the energy renovation of a 226-unit building located in the 13th arrondissement of Paris for a total of nine million euros.

Eco-renovation at the service of energy sobriety

Reducing the energy consumption of the residence is the ambition of this rehabilitation in the 13th arrondissement of Paris. The objective is to improve the thermal resistance of the building while modernizing its appearance through several insulation systems (terracotta cladding in two different shades, cement fiber cladding in two different shades, thin coating on insulation). The project involves numerous exterior renovations: thermal and acoustic insulation under an alternation of several finishes, waterproofing, flocking, railings, exterior joinery, occultation, ventilation system, lighting.

Terracotta: natural, ecological and sustainable

Wienerberger's Argelite, a terracotta cladding system, was installed on the façade. Used for over 5.000 years, terracotta is timeless. This ancestral building material draws its elements from a 100% natural raw material: clay. Inert and therefore recyclable, it requires no maintenance and allows for reduced upkeep for long-term cost control. Resistant to frost, shocks, and UV rays, it is also incombustible and, above all, offers major energy performance: high inertia, resistance to solar radiation, durability, and summer comfort.

For Jonathan Le Métayer, in charge of the site: « Unalterable and timeless, terracotta brings relief, strength, and identity to the buildings it adorns. Terracotta facade cladding is durable, weather-resistant, thermally efficient, and offers a sleek, simple, and modern aesthetic. The use of several insulation systems on the facade makes the project original and technical, while ensuring complete insulation of the building. The replacement of exterior joinery and blinds also significantly improves thermal and, above all, acoustic comfort, important given the proximity of the metro and the market. Tenants have already noticed a real gain in thermal comfort this winter, which reinforces the motivation of the construction teams and suggests equally positive performance in the summer. »

A two-year construction site in an occupied environment

The two-year construction project will soon be completed, with completion scheduled for the fourth quarter of 2025. The project will be carried out in an occupied environment, preserving residents' comfort thanks to measures implemented to mitigate noise and visual disturbances. This includes optimized management of various flows (users, residents, workers, deliveries) and local communication to facilitate coexistence between residents and technicians.

For Philippe Benquet, Chairman of the Acorus Group: "We are always mindful of the ecological footprint of the buildings we renovate, offering our clients as many eco-responsible products and materials as possible. In this regard, terracotta meets this need. It offers significant energy performance, is naturally ecological, and is recyclable: three advantages that are widely taken into account these days. Because thanks to the energy savings they allow, the renovation and rehabilitation solutions installed daily by our 950 technicians represent gains in the energy consumption of homes."
