The Storm Collar Ø 175 is an indispensable component for ensuring the water-tightness and weather resistance of your chimney flue system. Perfect for solid fuel and gas/oil appliances, including woodstoves, gas coal effect fires, oil and gas boilers, and any other solid fuel appliances, this robust storm collar protects your flue system from extreme weather conditions. Crafted with precision, the outer skin is constructed from 304 grade stainless steel and the inner skin from 316 grade stainless steel, each with a thickness of 0.4mm for added durability.
The insulation comprises compressed rockwool with a density of 200kg/m³ TWPro / 128Kg/m³, fully welded for a seamless finish.
