University roof renovation in Dunkerque
Located in the beautiful French coastal town of Dunkirk, one of the four campuses of the Université du Littoral Côte d’Opale (ULCO) specializes in marine research. Due to the aging roof of the main building, a comprehensive renovation process was carried out. The construction work spanned approximately a year, with university operations continuing without disruption during this time.
Particularly to ensure a uniform appearance in combination with the still intact roof surface and not to compromise stability due to the additional weight, the use of aluminium roofing was a firmly defined part of the public contract. The weather-resistant, easy-to-install, and above all, flexible warm roof construction by Kalzip with its innovative standing seam profiles was again able to fully convince in this tender, as the comprehensive complete system includes everything from the fastening material, insulation layer, to the roofing skin, necessary for a swift and targeted renovation.
Thoughtfully Roofed.
At the beginning of the work, the old roof was removed, and the underlying, still intact steel roof truss was used as a substructure to install the new vapor barrier and the mineral thermal insulation. Then, the original roof was repaired over almost 5000m2 with aluminium profile sheets, naturally considering openings for skylights and the integration of a connection for a solar system.
The aluminium profile panels of width 65/305 were fixed using composite clips and then safely folded. This guarantees a penetration-free roofing skin. These innovative composite clips (E-Clips) are designed to provide enough space for the mineral insulation layer with an appropriate build-up height. A compressible thermal insulation fleece, which can be separately removed again during dismantling, provides sustainable insulation. To facilitate potential maintenance work, walkways were installed after completion, and the extensively tested Kalzip roof path system SafetyPlus ensured optimal work safety at lofty heights.
A Wave of Everything: Tradition, Combined with Modern Architecture and Sustainability.
A roof form was deliberately chosen that slopes down to street level on the east side, rises again on the west side, and then breaks like a wave over the main entrance of the university. The resulting homogeneous roof structure reflects daylight, mimics the movements of the water, and from a bird’s eye view, ideally adapits to the given floor plans of the harbor quay and the surrounding streets and buildings.
As with almost all Kalzip projects, the new roof design of the main university building now impresses with the combination of traditional and modern elements and convinces with the use of an aluminium recycling alloy, even in rough coastal climates, with extreme durability and long-term ecological sustainability.
Considered with care. KALZIP.
