The non-visible roof system for double pitched roofs
Speaking from a technical point of view, the construction of the wooden roof has undergone several transformations over the years.
Initially it was managed entirely on site where great waste, inaccuracies and poor order and cleanliness of said site was always noticed. Subsequently, the pre-cutting in the company (a technique still used today) was first manual and then mechanized with multiple advantages.
To improve the technique and quality of the construction, at Grosso Legnoarchitettura we moved onto the pre-assembly of the structure on site, resulting in countless advantages. The aesthetics of the roof however have always been the same, without ever undergoing any changes.
What if we told you that there is a system with an advanced technique that offers a whole new finish?
We have devised a new roof panel system for double pitched roofs.

What is it about?
This system is made of pre-assembled panels with a wooden supporting structure that contain insulation (which can be panels or insufflation) in the middle. This is all enclosed by OSB panels on both sides, and a sheet over the first layer of OSB.
The surface above the panel is appropriate for the cover (sheath, tiles or sheet metal) to be laid on top, which will preferably be ventilated.
This system is a valid and improved substitute for the traditional concrete roof!
