Borrisokane Community College

Bauder Thermofol PVC single ply waterproofing system

Synopsis

Originally constructed in the 1970s on the site of former workhouses in County Tipperary, the Borrisokane Community College building needed to be demolished and replaced, having exceeded its serviceable life. The client wanted to bring a modern and refreshed appearance to what is a site of great historical significance and the new building’s roof played an integral role in achieving this; with the majority of the roof areas sloping inwards towards the open central courtyard area making them highly visible.

Project:	Borrisokane Community College

Roof Area:	3,650m²
Specifier:	Healy & Partners Architects

The specification

Roof areas totalling over 3,000m2 were fitted with Bauder’s Thermofol single ply fleece backed membrane, which is lightweight, visually appealing and possesses a high tensile strength of ≥ 1100N/50 mm. The system build-up included 160 mm of Bauder’s Thermotech Glass Insulation for superior thermal performance, ensuring the roof achieved the required 0.19 U-Value, and PVC roof profiles were also installed as a cost effective way of replicating the appearance of a standing seam metal roof. Bauder supplied new rooflights to deliver high standards of illumination, insulation and ventilation, and smaller single storey roofs were waterproofed with its bituminous Bauderflex system.
