Quality of Materials

Designing a lining system is a difficult task that requires hard choices, relating directly to product reliability, longevity and ultimately, the sense of security a good system provides to the homeowner. Wed like you to take a look at our criteria for making these choices.

Material Selection Selecting the right stainless steel is one of the most fundamental of design considerations. The steel alloy must prove long term corrosion resistance when exposed to the often aggressive environments created during the combustion and venting processes of various fuels. All other features of a chimney lining system hinge on the correct raw material composition. Careful consideration for both metal selection and material thickness makes VENTINOX the top choice for ensuring ease of installation, safety and reliability.

Material Consideration Its unique continuous weld construction renders VENTINOX air and water tight while providing superior strength and excellent flexibility. VENTINOX continuously welded stainless steel strip acts as a backbone and produces a lightweight liner 20% stronger than its competitors with a thickness of .006. FasClamp components make for a professional installation by eliminating pop rivets and the need for pre-drilling liners. The result is a penetration free connection from the heat source to the outside of the home. Here are some of the issues that are addressed by the manufacturing processes use to make VENTINOX liners:

Expansion: Since steel expands when exposed to heat, care needs to be taken to give it a shape that does not create stress within the system after it has been installed in a chimney. VENTINOX absorbs any expansion in its corrugations and does not twist or grow in length. Therefore, Tee sections dont get deformed and VENTINOX can be mortared solid at the chimney top, which creates a long lasting, watertight seal.

Liner Tightness: This is important for two reasons: First, to keep water vapors and other by-products of combustion within the liner at all times and second, to keep air (oxygen) out during a chimney fire. Using our unique and patented manufacturing process, VENTINOX liners are continuously welded to form an airtight conduit from the appliance to the chimney top.

Liner Strength: Liners are used in a construction environment. They must be strong enough to take some abuse. Welding the steel and forming it into specially designed corrugations creates great strength and enables VENTINOX to resist crushing and tearing.

Liner Weight: Heavier is not better. Excess weight is only a nuisance during installations, or when the extra weight could have negative effects on the chimney structure. The lighter weight of VENTINOX is possible due to our special manufacturing process. The other design criteria can be met without adding extra weight.

All VENTINOX Chimney Lining Systems are UL listed in the United States and Canada.

"I have been in the Chimney Industry for many years and used many products. But when my customers get their building permits and the inspector says "VENTINOX no problem, its the best out there" you know its the best. If the inspectors are sold on VENTINOX, so am I."
