Sapa Dualframe 75Si Pivot Windows
The Si Window System including pivot windows 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 2013 of the Building Regulations for thermal insulation.
The pivot windows work in harmony with all other Si windows systems.
Side Hung / Open In options: This option allows for numerous design variations such as louvres or perforated
mesh to be fitted externally to let the window open fully into the room to give the maximum amount of purge ventilation with the added security that nothing can fall through the open window.
