The Wall Sleeve Ø 150mm is designed to safeguard your chimney flue system as it passes through external walls. Ideal for use with various solid fuel, gas, and oil appliances—including woodstoves, gas coal effect fires, and boilers—this wall sleeve adds a layer of protection and ensures compliance with safety standards. Constructed from high-quality materials, the outer skin features 304-grade stainless steel with a thickness of 0.4mm, while the inner skin is made of robust 316-grade stainless steel.

The insulation comprises compressed rockwool with densities of 200kg/m³ for TWPro and 128kg/m³. The entire assembly is fully welded for enhanced durability, with specific distance-to-combustibles requirements of 50mm and 60mm for TWPro and KC systems, respectively. HETAS-approved and CE-marked, this wall sleeve guarantees regulatory compliance.

Installation is straightforward; the sleeve will need to be taper-cut if passing through the wall at a 45-degree angle, and all parts are secured with a Locking Band. Keep a safe distance from any combustible materials to ensure optimal performance.
