Mineral wool

Mineral wool with a density of 130 kg / m3, used in the prefabricated Progetto Legno System, offers a great thermal insulation efficiency (D = 0.036 W / m * K), rigidity and dimensional stability of the material over time. Our houses sound insulation system is ensured by the special structure of the basaltic mineral wool. This material reduces the risk of stationary sound waves between two surfaces and, in the case of compartment walls, ensures excellent isolation to air noise. Basalt mineral wool has high fire resistance, with temperatures over 1832 ° F without melt for up to 120 minutes.

OSB panels

OSB (Oriented Strand Board) panels used by Progetto Legno as a casing for indoor floor exterior lining are rigid panels pressed in three directions, made of pine-oriented strips. This slit orientation provides resistance, rigidity and stability to the hood. OSB panels can also be used damp thanks to a special surface treatment with resin that makes them waterproof and a not combustible material as well.

Plasterboard Panels

They are used for covering the inside of the external wall and for the inner wall. The panel is made up of cellulose fiber reinforced gypsum, which ensures rigidity, shock resistance and is used as carriers and suspended elements in the prefabricated wall system.

It can withstand loads up to 50 kg / sec., so suspended elements can be secured without the mounting of additional reinforcements.

It is an incombustible material and prevents the propagation of fire, but also an excellent sound insulator.

The use of cellulose fiber reinforced gypsum boards produces both energy saving (thermal conductivity = = 0.21 W / m * K) and reduced workload by saving time.

Glue Laminated Timber

Progetto Legno works only with high-quality glue laminated timber from Austria and is characterized by high load-carrying capacity, dimensional stability and the ability to form the timber components into almost any shape. We work with glue laminated timber in straight and curved shapes, thus opening up almost unlimited freedom of design in timber construction.

Areas of application: Detached houses and apartment buildings; multi-storey residential and office buildings; public buildings and administrative buildings; agricultural buildings; industrial and production hall-type buildings; sports halls and leisure facilities; roof truss and roof structures even in the exposed area; long-span main beams also in special shapes; supports and columns; ceiling structure or as support grid system.

Building with this technology will only bring our costumers great advantages such as the best form of innovation in therms of straight, cambered and in special shapes; large span lengths; high load-carrying capacity with low density; high dimensional stability due to gluing; fast and dry construction method; can be worked with simple tools; high fire resistance and chemical resistance; high thermal insulation properties; natural, renewable and 100 % recyclable building material; positive effects on climate protection due to storage of CO2.

Cork Panels

Cork is extracted from the Quercus Suber plantations, keeping the ecosystem unchanged with its natural regenerative bark cycle.

Cork, ecological, flame-retardant, impulsive, lightweight, is a 100% natural product that keeps its thermocouple insulation properties unchanged over time. We use this material for the outer coats of our Class A and A + ecological homes.

It is distinguished by its insulating properties, combined with the typical brown color, making it unique and unmistakable.

Wood Fiber Panels

Wood fiber is a plant material used as an insulator for roof and wall insulation.

It is produced by the processing of coniferous wood (pine, fir and larch) derived from scrap and residues of sawdust or from forestry. The raw material, therefore, is devoid of any chemical treatment and can be considered in unlimited availability.

Wooden panels are made of different thicknesses, sizes and densities ideal for insulation of wooden houses as breathable materials and avoid moisture deposits and mold formation.
