Project Description:

The AlkorDesign system was used recently on the roof of St Joseph's Primary School, Carryduff.

The roofing contractor on this job was Professional Roofing Services of Newtownstewart and the main contractor was O'Hare & McGovern Ltd. The architect, Samuel Stevenson & Sons Ltd., was looking for a membrane which would look similar to a zinc standing seam roof for the fan roof located to the rear of the main teaching block.

AlkorPlan 35179 in lead grey was chosen together with AlkorDesign profiles fixed at 950mm centres. The insulation and vapour control layer were mechanically fastened to the plywood decking and the Alkor membrane fully bonded to the insulation. St Joseph's roof was completed with Alkormetal flashings to the perimeter and around rooflight kerbs.

A small roof over the school's entrance was also completed in AlkorPlan 35176 reinforced PVC membrane. This area included the sides which had profiles attached to replicate lead covered batten rolls.
