CNC precision
Why factory precision matters on site
±1 mm precision helps panels and junctions fit predictably on site. This reduces rework risk and supports assembly quality. See timber frame panels, CLT panels and certified structures.
Factory and CNC parameters

What precise production delivers
Fewer corrections
Precise elements reduce the need to adjust assembly on site.
Predictable assembly
Assembly typically around 3–5 days per floor depending on the project.
Quality control
Production takes place in controlled factory conditions.

Frequently asked questions
Questions about CNC production, technologies and warranty.
ZTC uses mineral wool, cellulose insulation and wood fibre insulation. The company has an industrial Isofloc system for blowing cellulose and wood fibre insulation.

Panels are connected with long screws or special timber connectors. A wind barrier is used externally, a vapour control layer internally, and membranes are carefully taped across the building.

Airborne sound insulation in timber houses can be very good, especially with cellulose or wood fibre. Impact sound in intermediate floors should be addressed with appropriate floor and ceiling solutions.

For houses up to around 3 storeys, timber frame is often more economical. CLT may suit load-bearing structures, hybrid solutions or where exposed solid timber walls are desired.

After project approval and contract signing, production can usually be scheduled within 1–3 months. Manufacturing starts from around 2 weeks, while an externally finished house is typically completed within 1–2 months depending on scope.
After project approval and contract signing, production can usually be scheduled within 1–3 months. Manufacturing requires at least around 2 weeks. On-site construction depends on the scope of work — an externally finished house is typically completed within 1–2 months. Overall, a house assembled on site is often ready in approximately 4–6 months.
ZTC does not prepare architectural drawings. The company works from a client or architect’s project and provides structural solutions, manufacturing and assembly.
