"\nWhere a chimney system or vent penetrates through a deep profiled or pantiled roof, a lead flashing provides a weather tight joint. Lead Flashings are the traditional flue flashing used on tiled roofs. The lead is malleable and can fit in with the contours of profiled roof tiles as well as working well with slate roofs. The collar is lead, welded to the flashing, and sized to fit around the twin wall flue. With lead flashings, an appropriate storm collar is required.Our Lead chimney flashings are made of Code 4 lead and will adjust plus or minus 10 degrees. We stock two sizes, 125mm and 150mm suitable for TWPro twin wall flue systems.\n \nAPPLICATIONFor use on solid fuel and gas/oil appliances. eg: woodstoves, gas coal effect fires, oil boiler and any solid fuel appliances.\nCONSTRUCTIONOuter skin is made from 304 grade stainless steel and is 0.4mm thick.
