Capital Windows manufacture and supply the Dualframe 75mm Si suite.  This is the latest generation of advanced windows that offer superior thermal efficiency and performance owing to the advanced polyamide thermal break incorporated within the system.
It is based upon the tried and tested Dualframe system but further enhanced to create a new type of thermally efficient window.

High performance without complex glass specifications.

The unique thermal break technology within the Dualframe Si system means impressive U Values can be achieved without needing to increase the sealed unit specification at additional cost to the installer.
This means impressive U Values and Window Energy Ratings. 1.6 m2K U Value can be achieved using standard spacer in double glazed units or a greater 1.4 wm2K U Value is possible with sealed units incorporating a warm edge spacer bar. Overall a Window Energy Rating of A is possible.

Dualframe Si is suitable for commercial or residential application requiring a high performance window.

One advantage of the system is the larger vent and overall window sizes that can be created.  For commercial applications high rise windows can be installed.  For domestic applications bespoke window designs can be created for those clients requiring larger opening vents or larger windows generally.
Casement windows or tilt and turn windows are possible giving further choice.
