Video Description:

Follow along for a hands-on demonstration of cellular glass insulation boards for flue and chimney linings. In this video, we show how Class A1 non-combustible foam glass performs at service temperatures up to 430°C, test its closed-cell waterproof and vapor-tight behavior against condensation and acid-bearing moisture, and explain why its rigid, dimensionally stable body will not rot, sag, or add fuel to a chimney fire. Ideal for B2B buyers evaluating long-term flue insulation performance.
