Why Choose the SFlue BLK Firestop Plate?
Durability and Reliability:
The product is constructed with a dual-layer of stainless steel – an outer layer of 304 grade and an inner layer of 316L – both 0.40mm thick. This robust design ensures that the firestop plate is resilient over time, even when exposed to the high temperatures and operational stresses typical of solid fuel and gas/oil appliances. Not only does this mean longevity, but it also reflects a product that has been rigorously tested to meet demanding safety standards.
Safety Standards:
Complying with the Designation Number EN1856-1 T450 N1 D V2 L50040 G50, and with clear HETAS and CE approvals, the firestop plate provides peace of mind by upholding the highest fire safety standards available today. Its design ensures that there is a 50mm gap maintained between the flue and any combustible material, a critical factor in preventing potential fire hazards.
Ease of Installation:
One of the most commendable features of the SFlue BLK Firestop Plate is its ease of installation. The incorporation of twist-lock couplers simplifies the mounting process, reducing both the time and labor associated with installation. This makes the product an attractive option for both DIY enthusiasts and professional installers alike.

Durability Doubts
