The Ventilated Firestop Support Kit (WHITE) - Ø 150 is essential for ensuring safety and stability in your chimney flue installation. Specifically designed for use with solid fuel and gas/oil appliances such as woodstoves, gas coal effect fires, oil, and gas boilers, and other solid fuel appliances. Constructed with a robust outer skin of 304 grade stainless steel and an inner skin of 316 grade stainless steel, each layer is 0.4mm thick, providing excellent durability and resistance to heat and corrosion.
The insulation comprises compressed rockwool with a density of 200kg/m3. Both firestops and support clamp included in the kit are fully welded for added strength and safety. With a safe distance to combustibles of 50mm, this kit meets rigorous safety standards, being HETAS Approved and CE marked.
