X-LAM

For our creations we use the X-LAM (or CLT Cross Laminated Timber) construction system which involves the laying of solid wood panels, with crossed and glued layers. This construction system, now increasingly widespread, represents, together with the frame system, the best and most performing solution for wooden constructions.

The X-LAM method was born in the late 1990s in Austria in response to the needs of a group of sawmills eager for innovation and looking for new paths to take in the wood market.

The X-LAM panel is composed of wooden boards, usually made of fir, glued together and overlapped. Its appearance has revolutionized the way we design and build buildings, be they large or small.

The maximum dimensions of an X-LAM panel are 2.95 x 16mt and, based on the static requirements, they can count a number of different layers, therefore thicknesses. The bonding takes place by means of ecological glues whose manufacture is subject to strict controls by external bodies. A meticulous process that has the ultimate aim of guaranteeing quality and safety for all buildings that, if designed with the right precautions and fitted to perfection, allow the building to resist over time without any problem.

The X-LAM is appreciated for its innumerable advantages as it combines the characteristics of traditional constructions (in reinforced concrete), the healthiness and ecological properties typical of wood, improving the thermal inertia of the walls. Moreover, thanks to the excellent structural characteristics, the X-LAM allows to build stable and safe buildings in height.

In Italy the X-LAM technology has provided a quick solution in the reconstruction of the post-earthquake in Abruzzo, while in Milan, with the ambitious project “Cenni di Cambio”, it has made possible the construction of one of the largest residential neighborhoods in Europe, totally in wood.

Signs of Change, from the project of the Arch. Fabrizio Rossi Prodi, in its complexity, is an example of how this material, wood, lends itself to any need. The residential housing complex in social housing is composed of four nine-storey buildings that cover a total living area of ​​9,300 square meters, for a total of 124 apartments and a series of common spaces for recreational activities reserved for residents.

certifications

We care about your serenity, so we choose to put safety first, not only in all stages of production processes but also in the evaluation of materials, carefully selecting them, one by one, following the best European and international certification standards .

The wood we use for our creations, whether they are private homes or buildings with different destinations, comes entirely from the best Austrian manufacturers; every single wooden structural element is therefore guaranteed and certified.

materials and components

BITUMINOUS SHEATH

The bituminous sheath is one of the most used materials for waterproofing terraces and roofing plans.

It is a petroleum derivative and is generally marketed in prefabricated membranes, often equipped with glass veil armor, woven glass mesh, non-woven polyester.

Among the main technical characteristics of the bituminous sheath are the good mechanical strength, the high elongation at break and the high thickness (not less than 4 mm for the membranes applicable in a single layer). The latter is very important as it guarantees that the material can be walked on. The bituminous sheath, like all waterproofing materials, has the function of protecting the underlying layers of a roof covering from water infiltration.

BREATHABLE MEMBRANE

The breathable membranes are very thin sheets, generally made of polyethylene, polypropylene, bitumen and other synthetic materials, which perform a series of functions within a covering structure generally made of wood.

Among the functions performed by the membranes there are the possibility of regulating the amount of water vapor that affects the structure, protection from wind, dust and insects, protection from water coming from the roof covering, and reduction of summer radiation .

The breathable membrane is placed in the external part of the structure as, in addition to resisting rainwater, it facilitates the evaporation of humidity that manages to pass the steam brake and reach the structure.

STEAM BRAKE

The steam brake is usually placed in the inner part of the wooden structure. It restrains (this explains the reason for its name) the passage of steam that is transported from the warm air to the outside in the winter period. This could in fact cause the deterioration of the insulating materials if they remain wet for too long.

RADIANT SYSTEM

The radiant system is a heating system composed of panels that use the heat coming from the pipes placed under the surfaces of the room to be heated.

The circulation of hot water at low temperature (generally between 30 and 35 ° C) takes place in a closed circuit, covering a very high radiating surface. The heat of the water passing through the coil under the floor is gradually transmitted upwards, until the room environment is heated in a constant and uniform manner.

XPS – EXTRUDED EXPANDED POLYSTYRENE

The extruded expanded polystyrene (or polystyrene) is obtained from new or recycled polystyrene granules. It is used for applications in damp environments or in contact with the ground, and in case of high compressive stresses. It is used to insulate floors, walls and ceilings.

Plasterboard

Plasterboard is a building material that, thanks to its speed of application and its special thermo-acoustic qualities, is used both for renovations and for new buildings in private and public buildings. Its thickness varies according to the required application but the most common is 13 mm. In addition to the thermo-acoustic properties, we also mention the fireproof and the water repellent ones. It also favors the order and cleaning of the site as it is normally supplied in “ready to use” sheets.

With plasterboard it is possible to create against walls, dividing walls and false ceilings but also furnishing accessories such as bookcases and shelves.

X-LAM

The X-LAM panel (or CLT Cross Laminated Timber), is composed of wooden boards, usually made of fir, glued together and overlapped. With its appearance it has revolutionized the way of designing and building buildings, be they large or small. This increasingly widespread construction system represents, together with the frame system, the best and most performing solution for wooden constructions.

ROPE IN CONCRETE OR IN LAMELLAR WOOD

The curb, whether made of concrete or laminated wood, is the joining element between the reinforced concrete foundation, which is below ground level, and the wooden wall of the future home. This element, very important, must be studied very carefully and then realized with the same millimetric precision with which the entire wooden house will be laid.

LIGHTWEIGHT SCREEN FOR PLANT CONTAINMENT

It is a lightweight cement mixture made of cement and a specific additive with a foaming-colloidal action. This product gives a high insulating power and considerable lightness in the screed.
The lightened screed is used to cover electrical and hydraulic systems in civil and industrial homes and as a support base for underfloor heating systems.

ventilated crawl space

The ventilated under-floor cavity is a cavity that is built in the foundations of new buildings with the aim of keeping the structure dry through natural air recirculation.

BEADS ON SIGHT

The beads are planks of planed wood with male and female joints on the sides. They can be used for various purposes: in the building field they are positioned above the wooden beams of floors and roofs as closing of the structures. For this kind of processing beads with visible quality are used.

CROSSED plank

The cross plank is a second plank that is applied over the exposed beads with a structural and anti-seismic function; it can be made with non-visible quality beads, with raw boards or with OSB panels.

CLOSING TABLET

The closing boarding “closes” the entire insulating roofing package and creates the support base, first for laying the waterproofed bituminous sheath and then for the final roof covering. As with the crossed planks, this is also made of material with non-visible quality.

SELF-LEVELING SCREED

The self-leveling screed is a dry premix composed of special cements, classified sands and specific additives. It is used as a substrate layer in indoor environments for wooden, vinyl, linoleum, carpet and ceramic tile floors in private homes and public buildings.
The self-leveling screed has an excellent thermal conductivity, which is why it is particularly used on floor heating systems.

TRADITIONAL SAND CEMENT SCREED

It is a mixture composed of river sands, clean water and cement binder. The traditional sand cement screed is used as a substrate in internal and external environments to which reinforcing polymeric fibers or galvanized electrowelded meshes are added.

FOUNDATION PLATE

The foundation slab is the “base of the building” which transmits the entire weight of the structure to the ground in a uniform manner. They are made of reinforced concrete.

LAMELLAR WOOD

It is a very solid and resistant structural material produced by gluing wooden planks. Before being glued, the wood is dried to stabilize the amount of moisture. It is therefore a composite material, essentially made of wood, of which it retains the merits (among the main we recall the high ratio between mechanical strength and weight and good behavior in the event of fire), but it is also a new product, made on a scale industrial, which through a technological process of pressure bonding reduces the defects of solid wood.

 

ROCK WOOL

It is a natural material, recyclable and resistant to temperatures above 1000 ° C. Its versatility allows its use both for thermal insulation, and for the acoustic insulation of buildings or individual environments. It maintains its characteristics over time and is stable with changes in temperature and humidity.

OSB

“Oriented Strand Board” is a wooden panel made up of lamellas, of wood too, glued and pressed in layers to make it more compact. Thanks to the high mechanical strength and orientation of the scales inside the panel, the OSB is particularly suitable for structural bracing functions of wooden structures, but also for the ability to distribute actions concentrated on horizontal structures, such as floors .

EXTERNAL COAT FINISH

It is a process that involves the external shaving on the coat by applying two coats of premixed adhesive needed to create the base for the final intonachino. The latter is nothing more than a water-based coating characterized by high breathability and weather resistance.
