Storm collar inside ø125 outside ø250

The storm collar from the Metaloterm UK range is an essential accessory for waterproofing roof penetrations in concentric flue systems. This component is installed on the pipe just above the roof penetration and prevents rainwater from penetrating between the pipe and the roof penetration. Made of durable 316 stainless steel with a material thickness of 0.6 mm, the storm collar provides reliable weather protection. The storm collars are available in versions suitable for diameters ø80/125 and ø100/150 (outer diameters ø250 and ø275 mm).
