I used these insulating fire bricks for a custom high-temp project, and I’m genuinely impressed. They’re incredibly lightweight, which made handling and installation much easier than with dense bricks — especially when working overhead or in tight spaces.Despite being light, they insulate extremely well and stand up to high temperatures with no issues. Perfect for lining kilns, forges, or any setup where thermal efficiency matters.They cut cleanly, retain their shape, and really help reduce heat loss. Excellent quality — I’ll definitely be buying more for future builds!
