TECHNAL: Exterior joinery & facades

Industrial expertise at the service of aluminium joinery systems

Founded by André Bos in France, Technal has gradually established itself as a specialist in aluminum construction systemsThe company designs profiles and technical solutions for joinery manufacturers, facade contractors and construction companies.

These systems cover a wide range of applications:

• aluminum windows and doors
• sliding windows
• verandas and pergolas
• solar shading systems
• facades and curtain walls

In contemporary projects, these solutions directly contribute to the design of thebuilding envelope, in line with the requirements of RE2020 and energy performance objectives.

Custom-made joinery adapted to architectural projects

Technal develops aluminium solutions geared towards tailor-made projects, meeting the specific constraints of new construction and renovation operations.

Aluminium allows, in particular:

• the creation of large glazed surfaces
• a slim profile suited to minimalist design
• durability in the face of climatic conditions

These characteristics are sought after by architects and project managers, particularly for commercial buildings or collective housing.

However, as with all aluminum joinery, a technical limitation remains: the thermal conductivity of the material necessitates the integration of thermal bridge breakers to guarantee the expected performance.

An industrial system structured on an international scale

Technal relies on an extensive industrial organization, with a presence in more than 80 countries, eight industrial sites and more than 450 showrooms.

The Toulouse site is a strategic hub, bringing together design, testing, and production. Four testing and innovation centers validate system performance, particularly in the areas of:

• air and water tightness
• wind resistance
• durability of the finishes

These tests are carried out in compliance with current standards, such as CE marking requirements or the implementation rules defined by DTU 36.5 for the exterior carpentry.

A network of approved aluminum fabricators for implementation

Technal relies on a network of over 200 Approved Aluminium Installers in France. These professionals ensure the manufacture and installation of joinery using systems developed by the brand.

This model allows:

• a local adaptation of the projects
• mastery of site constraints
• client support from design to completion

"The quality of a work depends as much on its design as on its execution."

In practice, coordination between the manufacturer, the installer and the thermal design office remains crucial to achieving the expected performance.

An environmental strategy integrated into the design

Technal integrates environmental objectives throughout its industrial process. The company aims for a significant reduction in its carbon footprint, using several identified levers:

• increased use of recycled aluminum
• optimization of component supplies
• improving the energy efficiency of industrial sites
• streamlining transport and packaging

The joinery offered can incorporate up to 75% recycled aluminium, which helps to reduce the environmental impact of the works.

"The integration of recycled materials is a major lever for limiting the building's carbon footprint."

However, overall environmental performance also depends on the complete life cycle of the product, including extraction, processing and implementation.

Quality of finishes and durability of aluminum structures

Technal emphasizes the durability of its systems, particularly through the quality of the finishes and surface treatments.

Aluminium joinery products are covered by warranties on:

• the durability of lacquers (QUALICOAT class 2)
• the stability of the colors over time
• the resistance of anodized finishes

These elements are essential for structures exposed to the elements, particularly on facades.

In a concrete project, such as a curtain wall in a commercial building, the durability of the finishes determines both the aesthetics and the long-term maintenance costs.

Innovation and design at the heart of the Toulouse site

The Toulouse site brings together the design, engineering and development teams. This hub allows for the development of new solutions adapted to the evolving needs of the sector.

The teams are working specifically on:

• improving thermal performance
• the integration of home automation solutions
• Optimizing sliding systems

This collaborative approach between designers and engineers makes it possible to adapt products to new market expectations, particularly in terms of comfort and energy efficiency.

Technal has established itself as a key player in the aluminum industry, offering technical systems tailored to the current challenges of the building sector. Through innovation, industrial expertise, and an implementation network, the company contributes to the evolution of facades and joinery towards more efficient, sustainable, and integrated solutions.
