TFS™

A Timber Frame structure 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.

Structure

Timber Frame is a contemporary version, of American origin, of the half-timbering technique. The structure is composed of a skeleton of uprights and crosspieces, the set being braced with structural boards of wood derivative. A “platform” type Timber Frame structure is characterized by one-story high walls, with the first-floor slab serving as a platform for the next floor.

Watertightness

The Timber Frame includes 3 types of watertightness. The impermeability to water on the outside and resistance to air and water vapor from the inside.

The first is achieved by coating the structure with a rain barrier membrane or by external insulation of the same characteristics, on which are secured slats that will receive the outer coating (ventilated façade).

The second and third are made thanks to wood-based panels that we use on the inner face of the structure; in addition to their mechanical bracing characteristics, these panels act as a watertightness and water vapor regulation barrier.

Airtightness and internal water vapour tightness

Bracing

The structure is braced by wood panels inside and/or outside the building. The bracing allows the stability and rigidity of the structure under the horizontal and vertical loads.

Insulation

Timber Frame includes thermal insulation inserted between the uprights. A supplement can be placed inside and/or outside (ITI and ITE) to meet energy standards.

External cladding

Timber Frame can be completed by various types of exterior wood coatings (lined with overlapping panels, embedded, ajar, … according to architectural desires), composite wood (wood resin panels, wood fiber with cement, …), metal coating, ceramic, stone or possibly plaster.

Internal lining

Timber Frame is usually coated from the inside with plasterboard or wood liner.
