The SI (super insulated) window suite is the first in a new generation of window and façade products. Utilising advanced polyamide thermal break technology, Dualframe 75mm Si provides high thermal performance without the need to resort to complex and costly sealed unit specifications. Drawing from the tried and tested design principles of Dualframe, the Si specification also incorparates industry leading weather performance and security.

The SI range incorparates casements. tilt before turns, pivot and reversible windows.

With an increased focus on energy efficiency, it is valuable to use windows that help towards the overall reduction of heat loss. The Sapa SI window easily achieves an "A+" window energy rating and overall u-values can be as low as 0.9 W/m2K.
