Supaflu
The Ultimate Flue Liner For Your Masonry Chimney
Cast-In-Place Lining:
Supaflu is a unique system for lining and relining masonry chimneys. The system is based on a concept which originated years ago in Europe. The lining is cast-in-place within the existing chimney. There is no need to tear down the chimney. The method presently used is more effective and practical with the use of modern equipment and better technique.
The Product Supaflu is an insulating. light weight material, which can withstand high service temperatures. It consists of a factory blended proprietary mixture of cast-in-place aggregates to which water is added at the job site. The material is manufactured under strict quality control to insure consistent high quality.
Insulator
The Supaflu liner is an excellent insulator, in fact, a better insulator than any other flue liner of its kind. The high insulation keeps flue gases hotter and thus more buoyant. The condensation (creosote and soot) build-up in the flue is retarded. Also, the chimney's outer surface stays cooler, thereby reducing the risk of igniting combustibles around the chimney.
Sealer
The Supaflu liner fills in all the cracks, crevices and pores which may be present in the pre-lined flue. It stops leakage of toxic flue gases into the living quarters. A chimney fire, if it does occur, can be easily suffocated by shutting off the dampers on the heating appliances and chimney connectors. The Supaflu sealed flue will not permit entry of fresh air to sustain chimney fire.
Strengthener
The Supaflu liner becomes an integral part of the masonry chimney and reinforces the brick joints, fills cracks and voids and separations within the chimney.
Stability (Freeze-Thaw)
Laboratory tests have found Supaflu to be highly stable during alternate cycles of freezing and thawing. When subjected to these conditions the material did not show signs of surface deterioration.
Non-Corrosive & Asbestos Free
The formula is asbestos free and has no ingredients that can corrode or deteriorate under normal usage.
Suitable for all Heating Fuels
Supaflu material is resistant to acids and corrosive substances generally contained in the flue gases of wood, coal. oil or gas burning appliances. The liner can be properly sized to the appliances it is expected to serve. Method of Installation The chimney is inspected, prepared and cleaned using recognized chimney sweep procedures and equipment.
All openings in the chimney such as cleanouts, thimbles and fireplace openings are closed off and weak areas in the chimney are braced. An inflatable rubber former, called supaform, is lowered into the cleaned chimney flue. It is sized to the heating appliance(s) to be vented into the flue and to the available flue cavity. If the flue is tile lined, the tiles are generally removed to maintain a proper size flue. The supaform is inflated to the proper flue size and centered within the flue cavity by using spacers. Centering is accomplished at offsets and bends also. The special supaflu formula (just add water on site) is then pumped into the chimney (from the top) between the outside of the supaform and the inside of the chimney. When the supaflu is set, usually the next day, the former is deflated and withdrawn. The clean-outs and thimbles are reopened and braces removed. The heating appliance(s) are now ready to be reconnected.
The newly installed Supaflu liner extends from the base of the chimney flue to the chimney cap. The whole liner is constructed from material suitable for high service temperatures. The liner is capable of resisting corrosion, softening or cracking from the hot flue gases.
