Frequently Asked Questions
What is the distance to combustible material for a 5" twin wall flue?Every piece of twin wall flue in our collection has been tested rigorously and can be installed within 60mm of non-combustible material. This is a great advantage when fitting a flue system in a loft space or past ceiling joists as it means your system can be positioned relatively close to the timber work.
What is the outside diameter of a 5" twin wall flue pipe?The outside diameter of a 5" twin wall flue system measures 7" (175mm). The inner and outer steel skin of our twin wall flue pipe is packed with high-quality insulation which keeps the flue gases warm for a great draught and also ensures the flue can be installed within 60mm of combustible materials.
Can I install a twin wall flue system myself?Installing a twin wall flue system is a considerable task and may involve equipment like tall ladders or scaffolding if access to your roof is required. Connecting sections of twin wall flue pipe is technically very straightforward and specialist skills are not required, you'll still need to ensure that you follow building regulations for your own safety.
