Caldwell Windows
"Caldwells Windows recently installed a Cooltemper toughening plant from Unilam Machinery, in a bid to assert more control over its glass supply. Glass Times editor Nathan Bushell visited the factory in Wigan to see if it has made a difference."
"You either source your glass from a specialist glass supplier, or you aim for excellence when producing glass for your own needs - the market appears to be moving away from anything in between the two. Caldwells Windows chose the second option when its old toughening plant was due to be replaced last year."
