Our client needed a single glazed roof lantern replaced with a dual colour, thermally broken aluminium double glazed lantern. The external colour is 7016 Grey ant the internal is standard white, all powder coated. The Aluminium has an O.G.heritage detail to match the rest of the property. The double glazed units have Pilkington Active Clear on the outside and give a U value of 1.2. New lead flashing was required to the curb, this was also detailed to match the age and style of the property.
