NOVA Twin Wall Flue
Our premium NOVA twin wall flue system delivers superior performance for residential installations. Engineered with a unique multi-barb jointing system, it ensures gas-tight connections while maintaining thermal efficiency. Suitable for wood, multifuel, and gas appliances, this UK-manufactured system combines ease of installation with long-term durability, making it ideal for both new builds and renovation projects requiring modern heating solutions.
EUROPA High-Pressure Flue
The EUROPA high-pressure twin wall system withstands temperatures up to 1000C, perfect for demanding industrial applications. Designed for coffee roasters, generators, and heat recovery systems, its robust construction meets BS EN 1366-13 fire resistance standards. Available in multiple configurations, this commercial-grade solution offers exceptional safety and performance for large-scale installations requiring reliable exhaust management.
TUBEX PLUS Flexible Liner
TUBEX PLUS flexible flue liners feature 13mm high-density insulation for optimal appliance efficiency. Ideal for retrofitting in existing chimneys or creating sealed systems in challenging spaces, these versatile liners maintain thermal performance while allowing for complex routing paths. Their lightweight construction simplifies installation in both residential conversions and commercial buildings needing multifuel appliance connections.
Condensing Boiler Flues
Specially engineered flue systems for modern condensing boilers ensure safe, efficient operation. Our range includes both single and twin wall configurations that accommodate acidic condensate while maintaining aesthetic appeal. Compliant with current building regulations, these systems provide reliable performance for residential and light commercial heating installations requiring connection to external walls or vertical terminations.
Commercial Chimney Solutions
Comprehensive chimney systems for large-scale commercial installations include header configurations and large-diameter stacks. Engineered to handle high-volume exhaust from generators, biomass boilers, and industrial equipment, these solutions feature modular components that simplify complex installations. With full technical support and integration options for fire-rated penetrations, they deliver reliable performance across diverse applications from data centres to manufacturing facilities.
