Introducing the Single Wall to Twin Wall Increaser Ø 80 - Ø 100 mm, your perfect solution for connecting various heating appliances to TWPro flue systems. This increaser is crafted for compatibility with solid fuel, gas, and oil appliances including wood stoves, gas coal effect fires, and oil/gas boilers. Constructed with top-notch 304-grade stainless steel for the outer skin and reinforced by a 316-grade stainless steel inner skin, both 0.4mm thick, it ensures superior durability.
The insulation comprises high-density, compressed rockwool at 200kg/m3 for optimal heat resistance. Fully welded parts and a tapered design provide a seamless transition from single wall to twin wall. Keeping safety in mind, a mandatory distance of 50mm from combustibles like wood or plasterboard is required.
