HSB Timber-Frame Structures

HSB (timber-frame construction) is a building system in which the load-bearing frame is made of timber studs, with the cavities between them filled with insulation and finished with sheet material. We manufacture our wall, roof and floor elements to measure in our own factory in Kastamonu, complete with door and window openings and insulation, and ship them ready to install to the site — assembly then proceeds far faster and more precisely than with traditional masonry construction.

Key Advantages

• Light yet strong: a lower building weight than masonry structures, with high load-bearing capacity.
• Strong insulation: the insulation layer between the studs delivers thermal performance in line with passive-house standards.
• Fast assembly: the elements become wind- and water-tight within a few days of arriving on site.
• Sustainable material: timber is a renewable resource that stores carbon for the lifetime of the building.

The Elements We Produce

• Prefabricated wall elements: load-bearing and non-load-bearing walls, complete with door/window openings and service ducts, ready for assembly.
• Roof elements: insulated roof panels for a fast, watertight roof finish.
• Floor elements: prefabricated floor systems for an additional storey or intermediate floor in timber structures.
• Dormer elements: made-to-measure dormer extensions that can often be installed within a single day.

Why Our HSB Elements

We manufacture in our own factory in Kastamonu — 3,500 m² indoor and 27,000 m² outdoor — with no intermediaries and full control over quality and lead times. Our architecture and engineering team calculates every project itself, standard or bespoke. For insulation, vapour barriers and sheet materials we use tested products with an A1 fire rating on the interior face.
