High-traffic aluminum doors for public buildings and commercial buildings

A door designed for high-traffic buildings

In shops, offices, healthcare facilities, train stations, and apartment buildings, windows and doors are subjected to constant stress. Their mechanical resistance, reliability, and ease of operation are key criteria for building owners and asset managers.

To meet these requirements, the Lorillard Group developed the Grand Trafic aluminum door. Now distributed through the Lorenove, Lorebat, and Molenat sales networks, this solution was designed for environments where frequent use demands durable performance and controlled maintenance.

Performance tailored to ERP requirements

The High Traffic door is based on a multi-chamber design incorporating thermally broken strips. This configuration allows it to achieve a thermal coefficient of up to Ud 1,5 W/m².K , a level compatible with current building energy performance requirements.

Its flush 65 mm leaf accepts infills from 28 to 44 mm, opening the way to the integration of technical glazing or specific solutions according to the constraints of the project.

The joinery also displays certified performance in terms of air, water and wind tightness ( A4 / E7A / V*C2 ) as well as acoustic insulation of up to 39 dB , an asset in commercial buildings and spaces open to the public.

Durability and safety for intensive use

Durability is one of the main challenges for high-traffic buildings. The High Traffic door boasts a Class 7 endurance rating , corresponding to 200,000 opening and closing cycles , as well as high resistance to impact and wear.

Its corrosion-resistant aluminum construction also helps to minimize maintenance while ensuring consistent performance over time. Class 2 aluminum finishes are guaranteed for 25 years, a particularly desirable feature for equipment exposed to harsh weather and heavy use.

Security is also one of the range's strengths. Several devices can be integrated depending on the building's needs: three-point locks, panic exit devices, electric strikes, electromagnetic strips, or access control systems.

A response to the regulatory constraints of public buildings

In public access buildings, door and gate equipment must meet strict accessibility and safety requirements. The High Traffic Door has been designed to comply with regulations applicable to public access buildings as well as accessibility requirements for people with reduced mobility.

Multi-point locking and the option to integrate laminated safety glass enhance user protection while facilitating the daily operation of buildings. These features allow for its use in a variety of settings, ranging from administrative buildings to healthcare and educational facilities.

A benchmark commercial construction project in Chartres

The high-traffic door was recently installed at FITECO's new office building in Chartres. This project involved the teams from Lorillard Bâtiment Île-de-France for the design, manufacture, and installation of the exterior joinery.

The operation represents nearly 3,000 hours of work and includes the installation of 20 high-traffic doors, two automatic doors, 157 aluminum joinery units and more than 560 m² of curtain walls.

Smoke extraction and air supply frames were also integrated to meet regulatory requirements for fire safety and ventilation. In this context, the high-traffic doors contribute to the technical coherence of the building envelope while ensuring the management of daily traffic flows related to office activity.

A sustainable approach to technical joinery

Beyond its performance in use, the Grand Trafic door is designed with sustainability in mind. 100% recyclable and built to withstand repeated stress and external elements, it aims to minimize premature replacements and major maintenance interventions.

The Lorillard Group is also supporting the rollout of this product range by implementing new e-learning training modules for its sales network and building professionals. The aim is to facilitate understanding of the technical specifications, available equipment, and on-site implementation requirements.

With this solution, the manufacturer confirms its positioning in the market for technical joinery intended for commercial buildings and public access buildings, where the requirements of safety, longevity and energy performance occupy an increasing place in the specifications.
