WHY CHIMTEK?

Modern woodburning stoves and fireplaces are designed to provide maximum heating efficiency while producing a minimum pollution. The chimney can have major effect on how well these appliances perform under real-world conditions.

Chimtek combines quality materials and advanced technology to create America’s safest and most efficient liner for masonry chimneys. The double lining concept is an important part of Chimtek’s outstanding performance.

The Chimtek Inner Liner is made of a special blend of volcanic pumice aggregates and refractory cements to withstand extremely high temperatures and resist corrosive acids.

The innermost part of the liner becomes hot almost instantly when a fire is started, and remains warm during periods of sow burn. This improves the efficiency of the hearing appliance and reduces creosote formation.

The Chimtek Secondary Liner consists of very special grade of expanded clay aggregates called leca. The leca is mixed with a small amount of cement and poured in place between the Inner Liner and the outer structure of the chimney.

The high insulating qualities of the Secondary Liner results in efficient chimney operation in even the coldest climates.

Chimtek liner made of volcanic pumice and high-temperature refractory cements, with a round shape, high resistance to thermal shock, and added insulation value.

Safer

Chimtek is designed to withstand severe chimney fires without breaking or transmitting high temperatures to adjoining combustible materials. Chimtek has been successfully tested to the industry's toughest sagety standards.

More Efficient

Modern stoves and fireplaces reply on controlled combustion for maximum efficiency. A poorly insulated chimney results in poor draft and an oxygen-starved fire, which produces excessive smoke and wastes fuel. Poor Combustion is also a major cause of creosote formation. A Chimtek Liner System helps modern solid-fuel stoves perform efficiently by providing a warm, well-insulated chimney to ensure proper combustion over a wide range of operating conditions.

LONGER LASTING

A Chimtek Liner System, if properly installed and maintained, should last a lifetime.

BETTER VALUE

As might be expected, the initial cost of a Chimtek Liner System is usually more than traditional masonry liners. However, Chimtek Liner Systems normally require less cleaning, improve stove efficiency, and withstand conditions that would require replacing traditional liners. In the long run, Chimtek is the most economical choice.
