Review on 🔥 Lynn Manufacturing Fire Heat Insulation Brick - Soldering Torch Welding Insulating Block, Low Thermal Conductivity - Ideal for Kilns, Forges, Furnaces, Soldering - 2.5"x4.5"x9", Single Pack, 2300F-Rated, 3123P by Tara Ford

Excellent heat insulating, high temp resistant brick base for a Masterbuilt 30" propane smoker that would normally be placed on a decking deck. Fifteen (15) of these special stones were installed. Lightweight/high quality. I continued to buy bricks from the vendor to achieve the exact dimensions of the insulation surface I needed. The supplier ships the item immediately and carefully packs it in bubble wrap to ensure it arrives in perfect condition. The actual dimensions and thicknesses of the bricks are ideal for a complete, stable and washable insulating masonry under the smokehouse.
