Westcountry Glass, which is part of the Cornwall Glass Group, is making its largest investment in its 37 years of trading - £5M. The sealed unit manufacturer, currently located in Saltash, is relocating and expanding into new premise in Plymouth, called Concept House in Langage Science Park, quadrupling their factory size to over 40,000 square feet. Currently, the firm manufactures and supplies an extensive product range of double- and triple-glazed units to the South West of the UK. With the market growing, Westcountry Glass has experienced such an increased demand over the past five years that it has outgrown its already extended factory. This new expansion will increase the company's (and Cornwall Glass Group's) supply reach to new counties and customers, with exciting new possibilities.
