The core of the lightweight GRP chimney is constructed from class 3 orthophthalic polyester (GRP) which cures to form a strong, rigid and lightweight core. The chimneys can be manufactured to fit any roof pitch.
StackFast GRP chimneys can be finished with any cope and pot design and are available in sandstone, terracotta or traditional brick. To keep the weight of the stack to a minimum the cope and pot is constructed from the same GRP material as the core. Any pot can be replicated but standard rolled-top designs are available for an economic solution.
To ensure that the StackFast chimney stack will weather at the same rate as the main facades, all of our chimneys are finished with the customer’s choice of brick, slipped and bonded to the core. Any corbel detail can be incorporated in the design at no extra cost. The chimney only requires pointing on site to match the on-site mortar. StackFast chimneys are also available in stone or prepared for render.
StackFast chimneys are extremely easy to fit using a light crane or fork lift. They are fitted with lifting hooks which are supplied free of charge and removed after fixing. A full installation guide is supplied with each chimney.
