A Great Idea!
In 1963, Englishman Peter McFarlane embarked on research and development of a process that would effectively renovate centuries-old chimneys for modern use. Working closely with Great Britain’s National Coal Board, Peter introduced the cast-in-place chimney lining system. Thus, Supaflu was born.
Since that start, Supaflu has been the preferred restoration for tens of thousands of damaged chimneys in Europe and North America, including the Queen's Palace.

Why Supaflu?
Supaflu offers you many benefits, including improved structural stability, ease of maintenance, and suitability to all fuel types. However, Supaflu's most important benefits are improved efficiency and added safety.
Supaflu is designed to insulate your chimney while providing an effective barrier between the flue gases and your living quarters. Because of its liquid consistency, Supaflu fills all cracks and pores greatly reducing the chances that you will be exposed to toxic gases.
As an insulator, Supaflu is superior. In fact, the R-value is 500 percent greater than clay tile liners. This insulation ensures that flue gases remain hotter and more buoyant, thus improving overall venting efficiency and reducing buildup within the flue. Additionally, your chimney's exterior surface temperature will be lowered, reducing the chances that combustible materials surrounding your chimney may ignite. Supaflu is non-corrosive and is free of asbestos. Also, when subjected to alternating freeze-thaw cycles, Supaflu showed no signs of surface degradation.
Prior to installation, the chimney is inspected, cleaned, and prepared using chimney maintenance procedures and equipment recognized by our industry. Should the flue already be lined, the existing liner is removed.
All openings in the chimney structure, such as cleanouts, thimbles, and fireplace openings, are sealed, and weak areas in the chimney are braced.
The proper-size former is calculated for the particular heating application. The inflatable rubber former is then lowered and guided into the chimney flue. The former is then inflated and centered within the flue.
The Supaflu mix is prepared by adding water. The material is then pumped into the chimney from the top. It fills the space between the former and the inside of the chimney casing.
After the new Supaflu liner has fully cured, the former is deflated and removed from the flue, leaving a smooth, round, one-piece liner.
