The UK’s leading timber homebuilder needs little introduction. Stewart Milne Timber Systems (SMTS) has been at the forefront of delivering fabric first efficiency for many years and as part of the STA event programme, regularly opens the doors of its Witney facility for visitors.

The £10 million Witney facility is one of the largest and most advanced timber frame operations in the UK and since opening in 2003, has become the key factory that has led to SMTS producing approximately 10,000 homes a year.  With solutions to the housing shortage in short supply, SMTS has been vocal about the answers resting in the twin concepts of a fabric first approach combined with offsite manufacture. Both prove an effective way to maximise energy efficiency, deliver consistent factory-engineered quality and control build costs.

Between the two production facilities in Witney and sister operation in Aberdeen, SMTS can produce 16,000m of wall panels per week, 8,500 square metres of floor cassettes per week, 225 housing ‘kits’ per week or one house every 20-30 minutes. These quantities have positioned them as the UK’s market leader with wall, floor and roof panels typically designed to 3.6m x 2.4m sizes for ease of transportation, but can be made up to 9m x 3m. Production line flexibility means any customer requirement can be delivered with no restriction in the height, shape or configuration of panels.

Witney has the capacity to produce the entire SMTS product range. This includes the I-beam and solid timber joist floor cassettes, pre-insulated roof cassettes, plus the familiar SIGMA Build System open and closed wall panels. The Sigma II Build System closed panel product has been at the heart of SMTS success. This offers a high level of prefabrication with the BBA-certified Sigma II providing external wall U-values ranging from 0.25 – 0.10 W/m2/k, with very low levels of airtightness of 5 – 1.5 m3/h/m2 @ 50 pa and thermal bridging of 0.08 – 0.02.  Indeed, the SIGMA II exemplifies the fabric first approach.
