The TWPro MB Storm Collar Ø 100 is designed for ultimate water tightness in chimney flues, especially where they pass through the roof. Suitable for a range of appliances including woodstoves, gas fires, and oil boilers, this versatile collar protects against extreme weather conditions. Constructed with 304 grade stainless steel for the outer skin and 316 grade stainless steel for the inner skin, both layers boast a 0.4mm thickness ensuring durability and longevity.
The insulation consists of compressed rockwool with densities of 200kg/m³ and 128kg/m³ respectively, offering excellent thermal efficiency. All components are fully welded to provide robust construction. The product holds HETAS approval and CE marking, meeting all safety and performance standards.
For best installation results, secure the storm collar about 25mm above the flashing’s highest point and seal with silicone to ensure complete water tightness.
