This high profile, refurbished Office Building in the centre of the new quarter of Dublin, was a real challenge. All of the box roof-lights had an internal film installed years ago, which was all stripped off. We were working upside-down off high scaffolding and between structural framework. It was 50 degrees working up there! The film used was the RNO7 High Performance Anti-glare and solar heat protection film. We had to cut around each spider clamp while working up side down. We also completed two elevations to the vertical glass on all floors, with the N1040 Solar Film to reduce heat and glare. Lastly we carried out manifestations to all the internal doors throughout. This job was approximately 1000 sq.m.
