HSB is the Dutch abbreviation for houtskeletbouw (timber frame construction), a building method in which the load-bearing structure consists of a wooden frame of vertical studs and horizontal rails. This frame is clad on both sides (for example with OSB or plasterboard) and filled with insulation, after which the whole forms a strong, well-insulated wall. HSB stands in contrast to traditional masonry with load-bearing stone-based walls.
Characteristics
- Light and dry — the structure is light and is largely assembled dry, without long curing times
- Fast to build — walls are often prefabricated and assembled on the building site
- Good insulation — the space between the studs is completely filled with insulation, giving a high insulation value at a limited wall thickness
- Flexible — layouts are relatively easy to adjust
Build-up of an HSB wall
From the inside out, an HSB wall usually consists of: interior finish (plasterboard), a vapour-retarding layer, the stud-and-rail frame with insulation, a sheathing board, a water-repellent but vapour-open membrane, a ventilated cavity and finally the external facade finish (brick, wood or panel).
Points of attention are airtightness (a good connection of the vapour-retarding layer) and the detailing around openings, so that no moisture enters the structure. HSB is widely used in housing construction, for extensions and roof additions.
