Single skin liners are often called “Gas flex” and have a single skin of stainless steel that is designed for use with gas fired appliances and certain types of oil fired appliances that create flue gas temperatures less than 250ºC. These liners must not be used with wood or multifuel burning appliances.
We supply the high quality Wonderflex and Triplelock liners with a complete range of fittings to ensure a quick and easy installation. However, to keep options open many people choose to have Multiflex.
