VMZINC® Products: 10,000 m² of VMZ STRUCTURAL ROOFING - 2,000 m² of VMZ STANDING SEAM on the facade
Surface in zinc: 12,000 m²
Locating the Toulouse-Blagnac Aeroscopia Museum at the heart of a vast territory dedicated to international aeronautics was a natural choice. The museum, a genuine cultural space, demonstrates the growth of industrial tourism in the region. It features 6,000 m² of exhibition space and 4,000 m² of exterior areas that will house over 80 collectors civil and military aircraft. Designed by CARDETE HUET ARCHITECTS, this curved building is an architectural feat.
Clad with dark ANTHRA-ZINC® zinc, the building creates a subtle contrasting dialogue with the sleek lines and stainless steel of the neighbouring Airbus A380* plant. For this major construction, 100 x 73 x 23 m (L x W x H), contractors RAIMOND SAS installed 12,000 m² of made-to-order VMZINC® solutions. The latter, fixed onto “tri-dimensional” steel trusses weighing 500 tons, consist of:
• 10,000 m² of VMZ STRUCTURAL ROOFING in standing seam for the upper part of the museum. This “warm” (non-ventilated) roof is the only metal roofing system to have a French Avis Technique** for a double curve application. It enabled the architect to create the ovoid shape of the building and accentuate the slender eave coursing.
• 2,000 m² of VMZ STANDING SEAM on timber decking for the sides of the building. The easy installation of this technique ensures discreet junction with the roof, which contributes to the overall elegance and harmony of the building.
• VMZ STRUCTURAL ROOFING:
AN INNOVATIVE SOLUTION APPROVED BY THE CSTB (FRENCH CONSTRUCTION TECHNICAL AND SCIENTIFIC CENTRE)
The Technical Opinion was a decisive criteria for the architect and his technical inspection service, working to find an overall solution (zinc, fixing, insulation…) that was both certified by the CSTB and in keeping with the specific structure of the building (shape and weight). Working closely to meet its clients’ requirements, VMZINC® anticipated the review of its Technical Opinion in order to propose a solution that complied with the specifications of this exceptional project.
* Designed by CARDETE HUET ARCHITECTS.
** Technical Opinion delivered by a group of experts according to French regulations - Avis Technique n° 5/13-2346. 3
Architecture that contrasts with its immediate surroundings
The playful dimension of the museum is heightened by its oblong shape and its curved, continuous lines. This sweeping architecture catches the eye, and the ANTHRA-ZINC® surface aspect contrasts with the reflections of the stainless steel of the neighbouring Airbus A380 plant.
The matte colour which clads the entire building avoids the inherent reflections of metal roofs. It also creates a homogenous, continuous envelope that blends the roof and facade into one. The museum nestles in a circular arc around the pond, a water feature which offers both the reflection of the building and a green walkway that punctuates the exterior exhibition areas.
• PERFORMANCE AT THE TOP!
The upper part of the building is made up of a VMZ STRUCTURAL ROOFING roof system. This solution consists of ZINC PLUS and rigid mineral wool insulation that is 120 mm thick. It is mounted on a steel panel substructure with a vapour barrier. This technical zinc is protected on the underside by a 60-micron composite lacquer, enabling installation without an air gap.
VMZ STRUCTURAL ROOFING features numerous advantages:
- External insulation minimizing thermal bridges,
- Lightweight, compact warm roof, contributing to the reduction of the overall weight of the supporting structure,
- Malleability for the creation of complex, elegant shapes.
VMZINC® developed and patented a specific fixing clip system. The latter makes it possible to reduce the number of clips and optimise the time required for installation on the roof.
The fixed clip is supported by a spacer that passes through the insulation. The sliding clip is fixed to a stainless steel distribution panel, directly inserted into the insulation. It is easy to install on the raised surfaces of the profiled zinc panels prior to seaming, and allows them to expand freely.
• STANDING SEAM INSTALLATION
Double seam installation is the technique used, with panels that are 0.7 mm thick and have a centre distance of 430 mm (zinc spread out width 500 mm). This traditional installation technique makes installation quick and easy for the roofer. For steep slopes, intermediary locks minimize the length of the prefabricated zinc elements, making them easier to handle. The zinc was delivered in coils and formed in the workshop by the installation company using the layout plan designed upstream. Flexible and malleable, this material made work on the double curve roof of the AEROSCOPIA MUSEUM easy. Its aesthetic qualities ensure discreet junction of the warm roof and the vertical part that has cold roofing.

VMZINC® PRODUCTS AND ADVANTAGES
12,000 m² of made-to-order solutions fixed onto steel trusses:
- 10,000 m² of VMZ STRUCTURAL ROOFING installed using the standing seam technique on the upper part. The only metal roof system with a Technical Opinion for double curve application. It is supported by a slim complex that makes it possible to retain the ovoid shape of the building and accentuate the slender eave coursing.
- 2,000 m² of VMZ STANDING SEAM on timber decking for the facades. Easy, flexible, elegant installation ensuring discreet junction with the roof.
Building envelope clad with ANTHRA-ZINC® zinc. This dark, matte surface aspect contrasts with the metal roofing usually used in this type of architecture.
