In the PPRI zone, the La Reynarde 2 residence in Marseille is equipped with Lorillard wood joinery

This project, carried out by project management Vilogia and project management SOUL Architecture and BET Moduo, is divided into 2 buildings of 12 housing units each which run along the Penne crossing.

Each building is divided into three parts linked together by exterior vertical circulations, providing direct access to the accommodation. Metal passageways and staircases are the main means of access; no circulation takes place inside the buildings.

The architect designed a harmonious layout by creating two small side buildings of three floors (R+2) and a small central building of four floors (R+3), thus following the height difference of the plot. This system allows residents to benefit from an interior tree garden, which also provides access to the accommodation. Furthermore, the East-West orientation of the buildings promotes optimal sunshine for each accommodation.

Delivered last April, this construction project meets the quality charter for the art of building of the city of Marseille, which promotes environmental management of the site for sustainable projects.

For the joinery, the choice naturally fell on wood which finds its place in this residence built according to the RT2012 standard, however the conditions required for the joinery in the B2 PPRI fire zone required the manufacture of tailor-made flame protection windows. , combining aesthetics and performance.

Lorillard know-how in terms of security requirements

The Lorillard Group is not its first project in the PPRI zone and it is particularly recognized for its expertise. Drawing on its experience, the Group has a technical range specializing in wooden joinery. For this specific site in the PPRI fire zone, the type of wood chosen is larch, with a natural finish.

Larch was selected to enhance the high openings oriented East-West, thus providing optimal light. Most of these openings lead onto a balcony or terrace, adding extra appeal to the accommodations.

For this project, a total of 108 striking windows and patio doors from the Tradition range were custom-machined in Chartres and installed by Lorillard Bâtiment, 56 of which are 1/2-hour flame-retardant joinery. This wood joinery perfectly combines aesthetics and performance, there is in particular no aesthetic differentiation between fire joinery and those which are not.

The installation of this joinery required modifications to the dimensions of the openings initially planned by the architect, because all the panels were replaced to be in compliance with the fire safety Minutes (PV).

These flame-resistant joinery features specific tempered glass glazing and a unique design – including an intumescent fire-resistant strip – which allows them to resist the outbreak of fire, whatever the direction of the fire. . They are flame and smoke proof for 30 minutes (EW30 certification). In addition, they have great mechanical stability and excellent thermal insulation, with a Uw of 1.3.

This performance is essential to meet the requirements of the RT 2012 thermal regulations applied to these buildings. In addition, they are equipped with an additional soundproofing seal, contributing to airtightness and noise, particularly for facades overlooking the street of the residence.

The safety aspect of flame protection joinery combines harmoniously with the aesthetics, because their profiles have an appearance similar to that of traditional windows.

This characteristic is a real asset for preserving the architectural balance of the residence, which is located in a level B2 fire risk zone. The combination of their fire resistance, mechanical stability and thermal and acoustic insulation performance helps to guarantee the safety and comfort of residents.

This approach demonstrates the Lorillard Group's ability to provide secure and efficient solutions, while complying with construction standards and meeting high environmental requirements.

Thanks to the alliance between safety and aesthetics, larch flame arrester joinery contributes to the creation of a residential environment that is safe, pleasant and harmonious. The residence thus benefits from optimal fire protection without compromising its architectural appearance.
