Classic Mouldings NI has received full industry certification for its chimney stack products, from the CGMA (Construction Glassfibre Manufacturers Association). All members of the CGMA are committed to providing the highest quality products, to the highest possible environmental standards.

Classic Mouldings NI offer a range of GRP brick, stone & rendered effect chimneys to provide an extremely lightweight, affordable and simple way to add a chimney to a new or existing property.  All roof pitches are available as standard. Glass Reinforced Plastic has become a important material within the construction building products industry and the benefits of using this material for chimney construction is enormous due to its extremely lightweight and durable properties.

Our GRP chimneys are manufactured utilising the latest GRP technology and materials to provide a product that is both stunning in it's visual appearance and accuracy for replicating brick types. All brick and stone colours and textures can be replicated and samples of the actual brick are taken from site or pre ordered to ensure an exact match.  Our render chimneys are produced with a render texture and can be coloured to suit your on site render materials.  Bespoke cappings can be provided if required. A range of standard pots are available produced in terracotta or buff colours.

Our in-house design department provides working drawings for your approval with each order.

All chimneys are supplied ready to install with fixing instructions and standard rafter sealer washer type fixings. Installation is quick and easy to complete requiring no special skills.

We have several standard sizes offering a great degree of flexibility in terms of; size, corbel details and roof pitches. Further bespoke chimney options are available. Our in house design and tool making facilities can produce working solutions to meet your requirements.

We would welcome the opportunity to offer you a quotation.  Please contact 02890 432840 or
