Ayrshire technical College required replacement of their rooflights which are positioned over engineering workshop areas. The designated areas required good levels of light but with high quality transmission and insulation. The college needed a solution that was easy to install and so project time managed to ensure minimised noise and disruption. A series of Multivault GRP vaults were installed covering an area of approx. 800m2 or 15% of the total roof area providing an economic and yet highly effective daylighting solution.
