Do you feel cold drafts near your fireplace? That’s heat escaping and cold air invading your home. Poor chimney insulation isn’t just uncomfortable, it’s risky. Heat loss strains your furnace, increasing energy bills month after month. Worse, air gaps in your chimney can trap smoke or sparks, raising fire hazards. Insulation seals these weak spots and protects your family from hidden dangers.

Chimney insulation wraps the exterior structure. It seals gaps in bricks or stonework to block drafts invading your living spaces. This directly cuts heating costs by keeping warm air inside your home. Meanwhile, flue liner insulation focuses on the inside of the exhaust pipe. It maintains high temperatures, allowing smoke to rise quickly without cooling. This prevents dangerous creosote accumulation and improves draft flow.
Most homes require both solutions working together. The outer insulation stops energy loss through masonry cracks. Simultaneously, the inner insulated chimney liner reduces fire risks and carbon monoxide hazards. We assess your setup to recommend the right combination for maximum efficiency.

Vermiculite based insulation material handles extreme heat well, expanding to fill gaps in older flues. It’s poured as a ready mix around liners for solid protection. Meanwhile, mineral wool resists fire naturally, trapping heat inside chimney pipes without settling over time. Both options prevent drafts effectively while blocking moisture.
Metal systems need different solutions. A stainless steel chimney liner fits inside existing flues, improving draft power and resisting corrosion. Its inside dimension must match your chimney’s width exactly to work safely.
Ceramic blankets offer a durable wrap around fireboxes, reflecting heat inward while protecting nearby walls. We match materials to your chimney type, no guesswork.
