We are very fortunate to have Willie working with us to deal with our activities not only across Northern Ireland and Ireland, but also in England and Scotland.


Having been employed in the quality management side of public sector housing in Northern Ireland for 33 years, Willie spent his last 12 working with Specifications for PVCu, Timber, and Composite Windows & Doors together with related Glazing Specifications. He was largely responsible for the drafting/updating of these specifications together with ensuring their proper implementation at manufacturers.


During this time he not only gained a unique insight into the working and management of the fenestration industry across the province but became highly respected for his breadth of knowledge and ability, not only in resolving quality issues but also in advising on research and development.
