The Gotto D’oro client needed to remove the asbestos covering on the roof and spoke with us for a consultancy. We envisaged the possibility of doing the intervention using non-repayable fundings expected from the ISI INAIL tender, about which we are expert since 2002. We proposed them the roof restoration through the realisation of a photovoltaic roof architecturally incorporated. The warehouse couldn’t suffer huge loads and so we opted fora n aluminium roof, very thin and strong. The projects was articulated and full of difficulties that have been successfully overcomed by our company.

Stage of work: creation of the new roof structure
The new roof was installed before removing the old one, to not stop the productive activity. After the new roof creation, the asbestos domes have been disassembled from the warehouse’s inside safely.
Middle phase: new roof
New roof installation’s step
New roof particular
In this picture there is a very important particular: the roof isn’t fixed to the structure through bolts or screws. This makes the roof almost external, because there aren’t infiltration and oxidation’s risks caused by the discontinuity and the holes.
Furthermore to guarantee low slope we decide to use flaps of 24mt,unique elements for each one and without link
The high lenght of the flap can make serious problems to the structure, caused by the thermal expansion. Through this element the roof can flow longitudinally along the flap and make up for the thermal expansion’s effects. If there were some bolts to anchor the roof, they would have been object of stress with fracture risk in less than ten years. The roof realised will last dozens of years without any problem and maintenance.
Final step: new roof
New aluminium roof with photovoltaic architecturally integrated.
Conclusions:
the new roof had to be slight and strong and produce at the same time electric Energy. The solution choosed has been the best considering all the structural and technological restrictions . The client was really satisfied of the operation, which allowed : the improvement of the security system thanks to elimination of the asbestos risk, the restoration of a new covering with exellent mechanical features, improvement of the energetic efficiency of the company thanks to new roof’s Energy production. The intervention has been financed partly with the non-repayable ISI INAIL tender, that our client obtained thanks to us. So we followed and realised the project: from the fundings finding, to the implementation and the testing.
