Chimney Stacks
Calder’s range of GRP chimney stacks have the traditional appearance demanded by many local planning authorities, yet meet the needs of the modern building industry for an easy to install lightweight stack. These realistic and cost effective replicas can be quickly lifted into position, bolted to the roof trusses and finished with our lead flashing. We produce GRP stacks to suit most roof pitches and can match brick texture and colour to your building.
