HTS™

(Hybrid Timber System)

Hybrid System

The HTS™ system developed by rusticasa® combines the robustness of solid wood with the efficiency of a ventilated façade for superior thermal performance. With multiple exterior cladding possibilities, the hybrid system allows for a wide range of aesthetic options and architectural styles.

HTS
With 40 years of experience, rusticasa® has established itself as a benchmark in the development of timber construction systems, offering innovative solutions adapted to contemporary construction challenges. The company's constant technological evolution has resulted in the creation of versatile systems that meet both aesthetic demands and specific technical requirements.

The Hybrid system represents the latest advance in the rusticasa® portfolio. Designated as hybrid because it integrates a solid wood structure with a ventilated and insulated façade system, this solution is distinguished by its structural robustness, high durability and superior performance in thermal and environmental comfort.

The ventilated façade, insulated on the outside and clad with Japanese cedar wood, gives the system excellent thermal inertia and takes advantage of the hygroscopic properties of wood to ensure a healthier and more efficient indoor environment. All this, combined in a single system.
A HTS™ house is usually built on a concrete slab, on the ground or on a crawl space allowing a survey of the construction of 20 cm above the level of the ground. A band of peripheral insulate prevents the capillary rise in the walls.
Structure

PRIMARY: Solid Japanese cedar wood pieces, 80 mm thick, laminated and glued, positioned vertically or horizontally, form the primary structure of the walls, supporting the upper loads of the intermediate slab and roof.
The pieces fit together with tongue and groove joints and are fastened with structural screws.
This solid wood wall, which forms the interior facing of the house, is prepared with holes for the electrical wiring and air ventilation ducts (CMV).

SECONDARY: A second structure, fixed to the back of the first with structural screws, consists of 100x40mm studs and crossbars, spaced 600mm apart, forming a technical box to house the thermal insulation and the electrical and ventilation networks.

Watertightness

Airtightness and internal water vapour tightness

A breathable rain barrier membrane is placed over the thermal insulation supplement.
Water vapour migration from inside to outside the house is based on the principle of a breathable wall, without the use of a vapour barrier membrane.

Bracing

Insulation

Japanese cedar wood (80 mm) is an insulator that meets part of the building's thermal requirements. A strip of flax fibre is applied to the tongue-and-groove joint of each piece.
The wall's thermal insulation is complemented by 100 mm of wood fibre, placed in the space of the secondary structure.

External cladding

VENTILATED FACADE: The exterior cladding consists of a 20 mm thick openwork lining of Japanese cedar wood, fixed to support slats.
