A specialist glass company based in Knowsley is undergoing a £250,000 expansion involving new hi-tech machinery and an increase in staff numbers. Impact Safety Glass, based in Kirkby, manufactures and sells toughened glass and has also successfully branched out into aluminium frames. Directors John McDonough & Tony Harford have bought a new processing machine that will allow the firm to increase production & raise product quality. "The new machinery will enable us to offer a higher standard of finish," said Mr McDonough. "For example, if we were to produce 10 units of a particular product by hand it would be very difficult to ensure each one was made to an exact specification. The new equipment means we can do that." The company turned over £2.7m last year and projected revenues for this year are £3.5m. It employs 50 people and it is hoped a further 20 will be taken on over the next couple of years.
