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.
