Geocast produces realistic non-combustible fireplace beams designed to recreate the appearance of natural timber while providing a fire-resistant alternative for suitable stove and fireplace installations.
The range includes Classic, Heritage and Rustic beam styles in a choice of oak-effect finishes and sizes, making Geocast a popular option for traditional and contemporary fireplace projects where the look of timber is wanted without using a combustible wooden beam.
About Geocast
Geocast is a specialist range of non-combustible fireplace beams designed to replicate the grain, texture and character of real timber.
The beams are manufactured from non-combustible materials and moulded to create realistic timber detailing, allowing them to be used in fireplace installations where a genuine wooden beam may not be suitable because of combustible clearance requirements.
Non-Combustible Timber-Effect Beams
A Geocast beam provides the visual appearance of a traditional oak mantel without being made from timber.
This makes the range particularly useful above wood burning stoves and fireplace openings where heat exposure needs to be considered carefully.
Although Geocast beams are non-combustible, the installation must still follow the appliance manufacturer’s required clearances and the relevant installation guidance.
Geocast Classic Fireplace Beams
The Geocast Classic range offers a cleaner timber-effect appearance suitable for both traditional and more contemporary fireplaces.
Classic beams are available in finishes including Light Oak and Dark Oak, with different lengths available to suit a variety of fireplace surround and stove arrangements.
Geocast Heritage Fireplace Beams
Geocast Heritage beams have a more traditional appearance with deeper timber detailing and a natural oak-style finish.
They work particularly well with stone fireplace surrounds, exposed brick chambers, slate hearths and freestanding wood burning stoves where a more established or period-style fireplace appearance is required.
Geocast Rustic Fireplace Beams
The Rustic collection has a more heavily textured surface designed to reproduce the character of aged or reclaimed timber.
Available in natural and darker oak-effect finishes, these beams are particularly suited to cottages, country interiors, inglenook-style fireplaces and traditional stove installations.
Why Choose a Non-Combustible Fireplace Beam?
Genuine timber can require significant separation from a wood burning stove or fireplace because it is combustible. A non-combustible beam can provide greater design flexibility in suitable installations while maintaining the appearance of a traditional wooden mantel.
The exact position of any beam should still be determined by the appliance manufacturer’s installation instructions, heat output, fireplace design and relevant regulations.
