The concept

The MAS module is the standard unit of the first fully integrated solar and modular roof. All parts of the roof (the weatherproof surface, the structure, the thermal insulation) are integrated in a single product that is also customizable with an aesthetical inner surface and solar thermal, photovoltaic or PVT panels on top, that don’t require additional structures. 

Many green energy products are available today.
Installation, maintenance and cost of the existing products are still expensive, due to the lack of an effective integration among the different innovative technologies available.

MAS roof is the answer for the need to an innovative solar roofing system.

MAS has created an "all in one product":
integrated, patented, multifunctional by design, modular, with high structural performance (self supporting and anti-seismic), easy to transport and quick to install (“LEGO” type system).

Roof integrated concept
MAS roof concepts

The modules are assembled to make large self supporting structure, for the covering of both industrial or civil buildings, suitable for different use and architectural forms. The modules can be connected each other with connectors that provide a quick and fixed assembly.

Electrical and hydraulical connections are easy to connect too and proper tanks are placed on the side of the roof.

With these characteristics the roof becomes a complete appliance that generates energy, heating and cooling (solar and thermal energy), easy to transport and to install, a fully integrated modular roof at low cost.

Modular approach

Module dimensions (W, L, H): 1820 x 1002 x 225 mm (1,82 m²)
Technology: aluminium chassis with anti-hail glass, foamed inside with poliurethane
Weight: 62 kg (35 kg/m²)
Mechanical strenght: 250 kg/m²
Warranty: 25 years
Thermal transmittance: 0,18 W/m²K
Certifications pending: UNI EN 14509; UNI 9177

MAS modular

Self supporting "LEGO" system

We invented specific blocks for every need of the roof
Modules, supporting and insulating part of the roof are connected with specific tubes and plates. The gasket system and the protective glasses made a reistant barrier against harsh weather conditions. Side metal sheets assure an high insulation level all over the perimetral surfaces of the roof, the gutters are designed for water harvesting. Electrical cables and hydraulic plumbings are integrated in the module structure and available on the inside for installation and inspection.
The inner part of the roof is covered with specific metal sheets that insulate, hide and protect the exposed parts of the roof system.

MAS roof module

Roof module

With anti-hail glass surface

The basic external surface. The glass used, is a 3,2 mm tempered prismatic anti-hail glass, which is pasted on a peripheral frame aluminum-treated.
The glass can vary in colors.

MAS solar thermal module

Solar Thermal module

Anti-hail glass and a solar thermal panel

Below the anti-hail glass, there is a solar thermal panel, with network connections to the interior.
The solar panel is made of a thin absorbing pigmented aluminium sheet, associated with the hydraulic circuit made of copper pipes.

MAS photovoltaic module

Photovoltaic module

Polycristalline, 270 Wp

It is a photovoltaic panel, with personalized frame, consisting of 66 polycrystalline cells.
The power rating of the panel is 270 Wp.
The electrical box of the photovoltaic panel is inserted in the main body in its own seat and sealed to bring the electrical connections within the network in order to connect them and inspect them for maintenance.

MAS PVT module

PVT module

Hybrid solution - photovoltaic and thermal panel

The photovoltaic panel is glued to the thermal panel, this allows to get maximum performance even in the presence of hot and sunny climates and facilitates the melting of the snow during cold winters.

Light but incredibly solid

The module is made in a single industrialized process called PLS (poliurethane layers system). Parts are assembled together and foamed to make solid and light monolites. Fixings, sealing elements and covers are all standardized for the MAS roof system.

Up to three modules on long side (or five modules on short side) can be mounted on the roof without needings of supporting beams, for an approximate span of 6 metres. The weight of the roof is only 35-40 kg/m², with energy panels that are already integrated in the structure of the module.

The roof is earthquake proof due to his high mechanical performance with a patented connection system made of plates and tubes.

MAS insulating roof


The roof is made of a sandwich of materials that made him insulating for a value of thermal transmittance of 0,20 W/m²K, (comparable to 16 cm of pure rockwool).

The system includes:
- 3,2 mm of glass
- 35 mm double-glazing unit
- 30 mm rockwool
- 60 mm polyurethane foam
- 0,6 mm metal sheet (2x)

Moreover, where modules are connected:

- Aluminum and rubber gaskets
- Metal sheet and rockwool (50mm) fire-proof covers


The sealing system is made with perimetral gasket and closure caps.
It guarantees the ermetic closure between the interior and the exterior of the building.

The sealing rubber is covered and pressed on the glass surface by aluminium edges and caps. This make gaskets uv-resistant and weatherproof.

The sealing system is the same used for side closures of the roof.

Life cycle MAS roof


Local companies made the parts of MAS modules with the highest quality standards; MAS Roof is responsible for the assembling in the factory with a single industrial process.

The transport is operated by a single supplier in 20' containers.
With two container we can transport a 100 m² shed roof, including full length window and structure. The entire structure can be mounted in a day by two skilled MAS employes.

Once operative, the roof wil be able to provide a large amount of energy that can be used for the electrical needs and the conditioning of buildings.

At the end of its life cycle the roof is completely removable, as also all the parts of the modules that can be disassembled and recycled or reused.
