Stewart Milne Sigma II Building System

Stewart Milne Group can now offer a second generation Build System, which responds to the requirements of low energy low carbon homes and provides a robust and practical solution.

Stewart Milne Sigma II Building System

Stewart Milne Timber Systems’ Sigma II system is the only advanced closed-panel timber-frame/offsite construction product to achieve BOPAS accreditation. Offering an integrated approach with guaranteed performance and cost-effectiveness, this closed-panel timber-build system is the result of seven years’ collaborative research and development. It enables clients to tailor the amount of prefabrication required per project, and encompasses closed and insulated walls, prefitted windows and doors, and insulated pre-wrapped floor and roof cassettes. All this offers residential developers a fast build with vastly reduced trades interface and risk of error on site.

Sigma II’s fully integrated and comprehensive build system requires less supervision and construction risk. Following extensive testing, third-party assessment and technical compliance, Sigma II is BBA certified and backed by NHBC’s 10-year warranty.
