The Wall Support Corner 270-520mm - Ø 125 is designed to offer robust lateral support for your chimney flue system. Ideal for use with solid fuel, gas, and oil appliances such as woodstoves, gas coal effect fires, and boilers, this support ensures your chimney setup remains secure and stable. Constructed with high-quality 304 grade stainless steel for the outer skin and 316 grade stainless steel for the inner skin, each with a thickness of 0.4mm, it offers outstanding durability.
The insulation comprises compressed rockwool, providing a density of 200kg/m³ TWPro and 128kg/m³ KC, ensuring excellent thermal protection.
