Energy Efficient Double Glazing

Double glazing for efficiency

With significantly more glass than frame in a typical window, the glass element greatly influences its performance. Rylock suggests you start by choosing double glazing, to cost-effectively reduce heat loss by up to 51%.


On south-facing windows, you may opt for a high performance glass in the double glazed panel. Low-E double glazing comes complete with a low emissivity pane to further minimise heat loss. For west-facing elevations, your sales consultant is likely to recommend our double glazed unit with solar control glass. This ‘spectrally selective’ glazing reflects the infrared radiation emitted by hot objects.
