GCD International Turnkey Insulation Manufacturing Plants

Modular Transportable Designs
20 years experience

GCD International, one of the Sterling Industries Plc companies is renowned worldwide for it's high quality fibreglass and stone wool curing ovens, after 20 years design and manufacture.

Supplied to many major insulation manufacturers, GCD International ovens operate in diverse locations from Belgium to Taiwan.

GCD International International multi-density ovens are manufactured on a modular basis, skid-mounted, fully tested, expandable and pre-commissioned prior to dispatch to site throughout the world.

GCD International curing ovens are designed for product densities from 5 to 250 kgs/m3, and line speeds up to 85 m/min which requires great structural integrity.

GCD International Fibreglass Modular Insulation Curing Oven Pre-Assembled in Workshop.
Suitable for placement directly onto the foundations, the GCD International oven can be installed within 5 working days (refer figure above). By specifying a GCD International curing oven, our customers are able to reduce the critical path on greenfields plant development by up to six months compared with on-site construction. GCD International ovens can be installed in existing manufacturing lines with minimum disruption since they require minimal site works prior to installation.

For connection to the oven, a separate heating and variable air circulation system is also provided mounted on a skid suitable for speedy on-site installation. These systems are supplied fully wired with GCD International PLC systems for integration into our customers' PLCs, if required.


GCD International Heavy Density Fibreglass Insulation Curing Oven

Built to last!

GCD International ovens have heavy-duty flights and heavy-duty roller chain with pneumatic chain take-up and alarm system. Flights are supplied machined and stress-relieved and are fitted to chain in GCD International factory to achieve superior product flatness.

GCD International ovens are supplied with between 2 and 6 curing zones, depending on product output required. Oven drives and air flows are generally controlled with variable speed drives for fine tuning of the curing process and control of product temperature profile.

A free-standing combustion control cabinet with a full burner management system is fitted to the skid mounted circulating air heating systems.
