The University College London has recently installed acoustic secondary glazing as part of a new development programme managed by the main contractor, Strcuturetone Ltd.

Situated on a busy road, with a high volume of traffic and footfall from pedestrians, engineering students found it challenging to concentrate as the loud rumblings of nearby traffic breached the primary window systems.

Granada’s secondary glazing was specified as it is a system that would not only reduce noise from traffic but would also improve the thermal & security performance of the original steel windows.

Granada Glazing recommended the installation of 6.4mm laminated glass within the heritage horizontal sliding range. The window sizes varied where Granada designed, manufactured & installed multi-panel variants of their heritage horizontal sliding window system.

“Granada’s secondary glazing systems can reduce noise levels by up to 54 decibels (80%), this is apparent when walking into the treated lecture theatres. With enhanced security and the substantial reduction in noise, the students can concentrate in a learning environment fit for purpose.” Robert Walton (Business Development Manager), Granada Glazing.


Contractor: Structuretone Ltd
Products: 2, 3, 4, & 5 panel variants of heritage horizontal sliding window.
