Executive chairman Gerard Eadie CBE said: “We have been making and installing windows, doors and conservatories for Scottish homes for more than 40 years, and our desire to keep innovating and keep developing our products is as strong as ever. Today’s customers want beautiful, warm homes, with light and space and this can be achieved with the right windows or the right design for an extra room or extended space. We have continually developed our products to meet these needs and that is reflected in the latest accounts.”

Colin Eadie, director of CR Smith Manufacturing, added: “The expertise that resides in the factory, along with the investment we have made in the machinery, is integral to the success of the whole company. We are efficiently manufacturing the very best window products here in Scotland for Scottish homes and that capability is increasingly recognised by housebuilders.”
