The Wall Sleeve 45° Adjustable (Ø 100mm) is specifically engineered to ensure the safe passage of your chimney flue through external walls. Ideal for use with solid fuel and gas/oil appliances such as woodstoves, gas coal-effect fires, as well as oil and gas boilers, this robust sleeve is built to last. Constructed with an outer skin of 304-grade stainless steel and an inner skin of 316-grade stainless steel, each with a 0.4mm thickness, it offers exceptional durability.
Additionally, the sleeve includes compressed rockwool insulation with a density of 200kg/m3 TWPro / 128Kg/m3 for top-notch thermal protection. Designed for convenience, the pre-cut 45° angle of the sleeve can be manually adjusted to fit your specific installation needs, and the gap between the flue and sleeve can be filled with rockwool for added security. The product also ensures a safe distance from combustible materials, meeting all HETAS and CE approval standards.
