Project 1 - Alderley Edge High School for Girls


The Brief

Alderley Edge High School for Girls – an independent high-school in Cheshire – needed to update its windows and doors in time for the new term. The 1920s building still had single-glazed, steel-framed windows fitted that let in noise and let out heat. The headmaster hoped to improve energy efficiency and cut out distractions from the outside.

What We Did

The building needed 100 new windows replacing, as well as 2 new curtain walling units. We manufactured the windows using our Sapa Dualframe Si system, and fitted actuators to them to make them easier to use. They were glazed with our SKN 174 high-performance glass as this has maximum solar control and thermal efficiency values making it easier to keep the classroom at a comfortable temperature. Their insulation values are also significantly better. The school building was three storeys in places, and we manufactured and installed everything ourselves.

The Result

We completed the project during the summer holidays, so everything was ready when the pupils returned. The tight schedule was tough, but because we were in control of the whole process, we were able to complete it on time, and the school is now a more efficient, more attractive place in which to learn.
