The Long Roof Support - Ø 175 is an essential component designed for secure chimney installation in solid fuel and gas/oil heating systems, including woodstoves, gas coal effect fires, and oil and gas boilers. The outer skin is manufactured from 304-grade stainless steel, boasting a 0.4mm thickness, while the inner skin is crafted from 316-grade stainless steel, also at 0.4mm thickness. The insulation uses compressed rockwool, providing a density of 200kg/m3 TWPro and 128kg/m3, ensuring excellent heat resistance and durability.
The product maintains a safe distance from combustibles, with 50mm for TWPro and 60mm for KC, making it a trustworthy option for various installations. TWPro products are HETAS approved and CE marked, meeting the highest safety and quality standards. Secure installation is achieved with a Locking Band, ensuring the flue pieces remain tightly connected while adhering to the required distance from combustible materials like wood or plasterboard.
