Slim Double Glazing Upgrades

Proven to be 8x more energy efficient than original sash window single glazing, using our slim double glazed high quality units will ensure warmth and a reduction in heating costs.

You will be hard pushed to tell the difference from traditional windows. At just 12mm thick, the units will be virtually undetectable. They look like single glazed windows, from inside and out.

Our slim double glazed units combined with our bespoke draught proofing system will cut the level of audible noise from outside dramatically and increase thermal efficiency.
