One of Ireland’s premier boarding schools, Clongowes Wood College has a long and rich history since its inception in 1814 and indeed preceding that it was in 1450 that the first castle was built on the lands. Window refurbishment has started on this listed/protected status building and all glass being used is our IMC Slim-glaze range which offers low sight-line and low U-values while being able to glaze in the traditional look of the original style windows. Starting at 11mm thick these double- glazed units can optimise the insulation provided within the home with a 77% reduction of heat loss compared to the original single glazing which was first used. see more info on our website.
