The Si Window System has been specifically designed to comply with the ever increasing complexity of Secured by Design, Building Regulations, British Standards and other regulatory demands.

• Superior thermal performance is achieved with a unique polyamide thermal barrier enabling Si to comfortably exceed the requirements of Part L 2016 of the Building Regulations for thermal insulation.
• The Si suite consists of a high performance casement, tilt before turn, pivot, reversible and window wall.
