The Sflue (3109515) Heavy Duty Wall Band with a 152mm diameter is an essential component for safely securing chimney flues for solid fuel and gas/oil appliances. Ideal for wood stoves, gas coal effect fires, oil, and gas boilers, this wall band provides unparalleled support. Constructed with high-quality materials, the outer skin is 0.4mm thick 304-grade stainless steel while the inner skin is made from 0.4mm thick 316-grade stainless steel.
The insulation comprises compressed rock wool with a density of 230kg/m3, encapsulated within twist-lock couplers for secure placement.
