Mixture of fixed and top hung SAPA 75Si windows This energy efficient window system helps towards the overall reduction of energy consumption. The Si suite offers superior overall window performance without the need to resort to complex and costly sealed unit specifications.
The Si window suite can achieve an “A+” Window Energy Rating and where specified ‘U’ Values down to 0.9 W/m2K. Perfect for keeping down the energy bills in a large space such as a school that needs constant heating in cooler weather.
As well as achieving exceptional thermal performance, the Si suite attains superior weather performance for water tightness, air permeability and wind resistance.
ST II single doors. We supplied and installed two Stormframe STII High Traffic aluminium single doors. We frequently use these high traffic doors as they provide the ideal solution for any school situation. Adaptable for any door hardware as well, with a simple hook lock, Multipoint lock with a choice of lever or lever handles, Electromagnetic locks, Panic exit devices and/or Electric strikes.
The STII is PAS24:2012 and 2010 Equality Act Compliant. These doors can also be coupled to the Dualframe 75 SI, as we did on this project.

9 Crown fixed windows with curved heads Crown Windows can be made to replicate your existing windows or configured with a new arrangement of fixed and opening windows to create an individual look. In this instance, crittall replacements with either a 52mm or 75mm frame. We also used this system to bend for the curved heads, which fitted a treat.
