Technical Excellence
Timber Construction Technologies
Modern prefabricated building systems designed for performance, sustainability and speed. Explore the engineering solutions that make timber construction the future of building.
Timber Frame Construction
System Overview
Timber Frame Systems
Prefabricated timber frame panels are produced in the factory and delivered to the construction site ready for installation. Panels include structural timber framing, insulation and structural sheathing.
CLT Structural Panels
Mass Timber Technology
CLT Structural Systems
Cross Laminated Timber (CLT) panels are large structural wood panels used for floors, walls and roofs in modern timber buildings. These engineered mass timber elements provide exceptional performance and sustainability.
Advanced Solutions
Hybrid Timber Construction
Many modern projects combine CLT structural elements with prefabricated timber frame facade panels. This hybrid approach allows optimized cost, structural strength and thermal performance.
Cost reduction vs. pure CLT

Supplier, contract & timeline
Hybrid systems maximize the benefits of both technologies - CLT structural core delivers mass timber performance, while timber frame insulated envelope provides superior thermal efficiency. The result is a cost-effective, high-performance building delivered under one contract and one point of accountability.
Key Benefits
Performance Features
Superior Thermal Performance
Cellulose and wood fibre insulation pressure-filled using the Swiss Isofloc industrial system. Typical wall U-value 0.15–0.20 W/m²K - passive house standard achievable.
Exceptional Airtightness
Factory-controlled production and glued membrane connections achieve airtightness n50 < 0.6 - with n50 = 0.24 recorded on completed projects.
Fire Resistance
CLT panels tested to fire resistance EI 120. Timber frame panels can be specified with additional fire protection to meet any national building regulation requirement.
Acoustic Performance
CLT acoustic performance Rw up to 65 dB. Mass timber provides natural sound attenuation - meeting residential and public building acoustic standards across Europe.
Structural Precision
Hundegger CNC manufacturing to ±1mm tolerance. Every element is cut from a digital production file - no on-site adjustments, no waste, no delays.
Sustainability
FSC and PEFC certified timber available on request. Wood is a carbon-storing, renewable material - timber construction actively contributes to reducing the carbon footprint of the built environment.
Advanced CNC Manufacturing
Quality Control
Precision Manufacturing
All structural components are manufactured in a controlled factory environment using advanced CNC equipment. This ensures superior quality, consistency, and precision that is impossible to achieve on-site.
Factory production eliminates weather dependencies and allows systematic quality checks throughout the manufacturing process.
Versatile Solutions
Applications
Private Residential
Single-family homes and villas - individually engineered from your architect's drawings. Timber frame panels deliver fast assembly, high energy efficiency and a healthy indoor climate.
Multi-Unit Residential
Apartment blocks and townhouses up to 8 storeys. Timber frame for lower buildings, CLT or hybrid systems for mid-rise - all delivered under one contract with fixed price.
Public Buildings
Schools, kindergartens, community centres and public facilities. ZTC has delivered public timber buildings across Latvia, Swtizerland and Norway — meeting elevated fire, acoustic and structural standards.
Commercial & Infill
Office buildings, commercial facilities and infill panels for steel or concrete frames. Lightweight timber infill panels are ideal for urban renovation and facade upgrades.
