The Insulated Timber System (ITS™) uses ISOLAM® self-supporting panels for all structural and house-covering elements. The glued laminated wood panels insulated with cork at its core, offer a high coefficient of thermal resistance and allow a very fast assembly.

ITS™ is born from the conjunction of the log house constructive technique with the Timber Frame system. In addition to reconstituting the log with glued laminated wood, adding cork in its core to increase its thermal performance, the pieces are joined together to form self-supporting structural panels, thus giving the constructive system unmatched benefits, both in terms of insulation and for its fast construction (2 days for walls and roof assembly).

ITS™ houses, mounted on both sides of the finished walls, can be delivered fully equipped, including exterior carpentry, as well as the channels for built-in electrical installation, offering a rapid execution time without setting or drying times, characteristic of the construction with wet conglomerates (traditional construction).

The reduced thickness of its walls optimizes the living space (+/- 8% more than in bricks), and increases the comfort of its occupants, thanks to the naturally perspirable materials that regulate the interior humidity, with low thermal inertia and the absence of thermal bridges (+/- 30% of heat loss in traditional construction).

Suitable for any type of site (landlocked lot, narrow, unstable, steeply sloped, …), the ITS™ construction is up to 10 times lighter than a concrete construction and 20 times lighter than steel, requiring much less substantial and less expensive foundations and is suitable for low lift fields, or in poorly stabilized areas.

The solution to a dry, clean, fast and energy-efficient construction.

Technical description

FOUNDATIONS

An ITS™ house is usually built on a concrete slab, on the ground or on a crawl space, allowing the construction to rise 20 cm above ground level. A sealing strip at the base prevents the rise of moisture in the walls through capillarity.

THE WALLS

Structure: ITS™ house consists of ISOLAM® wood panels formed from joined glued laminated wood logs, insulated with cork at their core. The individual pieces of wood are stacked through a longitudinal fitting system, forming structural walls which are intersected at the angles with vertical wall studs to consolidate and to brace the building.

Sealing: each piece of wood is treated at the factory according to biological risks and exposure to weather. Likewise, the fittings are designed to prevent the entry and stagnation of rainwater.

Airtightness and internal water vapor: in each enclosure area,


a sealing strip ensures tightness between each piece of the construction. Wood and cork, due to their insulating characteristics, prevent the creation of dew points that are detrimental to the building’s durability.

Insulation: the ITS™ house is highly insulated. Its coefficient of thermal transmittance is U = 0.29 W / m2K, according to EN 12664: 2001. On the other hand, noise reduction is 33dB, according to ISO 717-1: 2013.

The outer coating: ISOLAM® panels are finished in the factory leaving the wood visible on the outside, with the application of a perspirant outer lacquer.

The inner coating: as with the outer coating, the ISOLAM® wood panels are generally visible in the interior and are coated with a perspirant varnish (clear or white). Other coating materials, such as plaster, stone, (…) may be used as finishings.
