Parallel opening windows double airflow for school
2nd February 2016


Devon based fabricator Interframe has for the first time manufactured parallel hinged sliding windows using only Rehau total70c chamfered profile.

The windows, at the newly opened Steiner Academy in Exeter, were specified because they could provide almost twice the free air flow of standard top hung or casement windows.

Compared with a casement window, a parallel window increases air flow all the way around so that fresh air is drawn in at the bottom and warm, stale air is expelled at the top.  This creates full circulation of the air within the room and, at the same time, the balanced air flow around the entire opening reduces the potential for draughts.

At Steiner Academy, the windows were specified by architects AHR Global in Bristol.

A key benefit of parallel windows is that they don’t impact on the look of a building’s façade and maintain a consistent reflective view, with low G-value glass used to reduce solar gain.  At Steiner Academy, all of the 150 plus windows, doors and screens installed were also coloured in a smooth RAL 7016 grey foil.

REHAU’s commercial sales manager Steve Tonkiss said: “Interframe was able to meet the exacting requirements of this project using our standard Rehau Total70c profile. This was a huge advantage because it meant that they weren’t holding stock of additional profiles and, because of the strength of the system, they could manufacture the large window sizes required.”
