Rector & Techniwood: the combination of industrial concrete and wood prefabrication for intelligent decarbonization of buildings

For its return to the BATIMAT show, RECTOR, a specialist in the prefabrication of concrete elements, wished to share its stand with TECHNIWOOD, a French industrial leader in biosourced prefabricated wooden facades. This association aims to offer off-site industrial wood and concrete prefabrication solutions for intelligent decarbonization of buildings.

A shared vision of sustainable construction and off-site construction

Thanks to its ranges of low-carbon prefabricated products and systems, RECTOR is resolutely committed to decarbonization, an approach that is part of the company's CSR strategy.

Specialized for 10 years in the manufacture of wooden construction systems (wooden framework, frame, CLT) and particularly prefabricated wooden facades with its innovative product Panobloc® 100% made in France, the TECHNIWOOD group also displays its desire to be part of a virtuous approach in favor of the energy transition.

For Côme Lesage, Strategic Marketing Manager at Rector: “We had the opportunity to meet the Techniwood teams on common prescription actions, and very quickly, we realized that our visions and our values ​​were very similar. »

The two companies believe in the complementarity of concrete and wood materials because each has its own advantages which justify their implementation in the best place to meet the constraints of sustainable buildings (thermal, acoustic, fire, low carbon, etc.).

To promote the development of off-site construction, RECTOR and TECHNIWOOD are convinced that it is essential to:

• draw on the skills of general and structural contractors and support them as far upstream as possible in the transition to a change in construction methods;
• offering innovative industrialized solutions giving free rein to the creativity of architects. These should not require implementation techniques that are too disruptive to speed up construction times and keep housing at an acceptable price level;
• aim for industrial excellence through the use of digital tools, such as the Caméléo® configurator from RECTOR, compatible with the acceleration of BIM worksites.

Complementary systems to carry a global offer

With the common ambition of being the reference in its field for sustainable construction, the two companies rely on an offer bringing together:

• the prefabricated floor-slab structure in Caméléo® low-carbon concrete without load-bearing wall from RECTOR, which incorporates all the resistant elements in the thickness of the floor. Composed of a framework of posts and a reinforced concrete slab, Caméléo® allows the construction of scalable buildings whose interior spaces and facades can be easily reconfigured over time. Thanks to its great adaptability (no falling beams or heavy partitions), the open floors lend themselves to all configurations and the building constructed today can easily be adapted to new uses tomorrow. The transformation can thus be planned from the design of the structure by carefully choosing the location of the posts. RECTOR thus gives architects full latitude to express their creativity in an evolving framework, while minimizing the costs and environmental impact of conversions. Caméléo®'s eco-design systematically favors the right material in the right place and accompanies the constructive mix, especially wood, from the very first sketches.
• the eco-designed Panobloc® CLT facade panel with integrated insulation from TECHNIWOOD which guarantees excellent performance of the building envelope (in terms of thermal, fire and carbon) and faster waterproofing and air-proofing of the site . Panobloc® is a structural wooden trellis made up of a stack of crossed plies made up of alternating solid wood slats and insulating filler strips occupying the free space between the wooden slats. Manufactured using a fully automated industrial process under quality assurance, Panobloc® facade panels have a negative carbon impact. They provide high quality of use and comfort to the occupants (thermal and acoustic insulation, air quality, etc.).

This combined system offers all the benefits of prefabrication (saving time, resources, costs and reducing nuisance on site) while guaranteeing a long-lasting building, with a greatly reduced carbon impact, compliant with RE2020.
