Chimney lining

There are several types of chimney liners:

• Stainless steel liners – The most common choice for wood-burning stoves. They are durable, corrosion-resistant, and can be installed in most existing masonry chimneys.
• Clay tile liners – Common in older masonry chimneys. They work well when intact but can crack over time and are not always suitable for modern stoves.
• Pumice or concrete liners – Typically installed when building a new chimney. They provide excellent insulation and longevity.

Why install a chimney liner?

• Improves the safe removal of smoke and dangerous gases such as carbon monoxide.
• Reduces the risk of chimney fires by helping keep flue gases hotter and reducing creosote buildup.
• Improves stove performance by creating a correctly sized flue for better draft.
• Protects the chimney structure from heat, moisture, and corrosive combustion byproducts.
• Helps meet building regulations and manufacturer installation requirements.

When do you need one?

If you’re installing a wood-burning stove into an existing masonry chimney, a stainless steel flexible liner is typically the preferred solution. Before installation, the chimney should be professionally swept and inspected to ensure it’s clear of soot, creosote, nests, and structural defects.

A correctly installed, insulated chimney liner can last 15–30 years or more, depending on the liner grade, fuel used, and how well the chimney is maintained. Annual sweeping and regular inspections will help maximize its lifespan.
