The Double Storey Straight-Up Flue Kit – 5″ Twin Wall Flue (125mm) is a comprehensive chimney flue solution designed for installing a wood burning or multi-fuel stove where a chimney is not already available. Designed for double-storey properties, this complete twin wall flue system provides the essential components required to safely route a flue through two floors and out through the roof. The straight-up configuration makes it an ideal choice for installations where the stove is positioned directly below the desired flue termination point.
This 5″ (125mm) twin wall flue kit includes the key components required for a complete internal installation, including twin wall straight lengths, a standard adapter, storm collar, weathering rain cap, firestop components, roof support and adjustable roof flashing. The insulated twin wall construction allows the system to pass through internal floors and roof spaces while maintaining the required separation from combustible materials. Additional straight lengths can be added where greater flue heights are required, providing flexibility for different building configurations and installation requirements.
Designed as a convenient complete package, the Double Storey Straight-Up 5″ Twin Wall Flue Kit helps simplify the process of specifying and installing a twin wall chimney system. The system can be configured to suit the height and layout of your property, while the supplied roof support and flashing provide secure support and weather protection where the flue exits through the roof. Twin wall flue installations should always be designed and fitted in accordance with the relevant regulations and by a suitably qualified installer. 1x 37-125-026(BL)2-125-026(SS), 5x 37-125-010(BL)2-125-010(SS), 2x 37-125-077, 1x 37-125-011(BL), 1x 58-125-067(BL)15-125-067(SS), 1x 58-125-182(BL)15-125-082(SS), 1x 37-125-090(BL)2-125-090(SS), 1x 58-125-051(BL)15-125-051(SS), 1x 12-2-TILE
