David H Wright are proud to be at the front a new energy efficient conservation movement. New ultra-thin double-glazing technology has now been approved by the conservation trust in Edinburgh, and we are proud to say that we are now in touch with local conservation

boards to push for a similar result. This would mean that, if the motion is approved, listed building will be able to replace existing single glazing with double-glazing into the original fittings. This new technology offers the look and feel of single glazing with the economy of double-glazing.
