Manufactured in controlled factory conditions, each solution in the Donaldson Timber Systems range is designed to deliver consistent quality, faster build programmes and confidence from first project to long-term partnership. From open panel to advanced closed panel systems, our products combine precision manufacturing, robust technical design and proven site delivery, helping customers to build smarter, faster and better, without compromise.
Open panel timber frame systems
Our open panel timber frame systems offer a flexible, cost-effective solution for high-volume housebuilding. Designed for speed, accuracy and quality, they provide a proven route to offsite construction efficiency. Manufactured in controlled factory conditions, each panel delivers reliable performance and faster build times. All of our wall systems are compatible with a range of floor and roof systems.
Pre-insulated panel timber frame systems
Pre-insulated timber panels combine the benefits of offsite manufacture with exceptional thermal efficiency. Factory-fitted insulation ensures consistent quality, reduced waste and faster site progress. These systems help meet future homes and low-carbon targets while keeping build costs under control.
Closed panel timber frame systems
Our closed panel timber frame systems, including the Sigma® II platform, deliver high performance, precision and speed. With insulation and service zones factory-installed, they reduce site labour, improve airtightness and support Modern Methods of Construction. Certified by NHBC, BOPAS+ and BBA, they’re built for quality and long-term confidence.
