Today, IMPER ITALIA’s many years of experience in formulating and producing membranes with weight to thickness ratios of less than 1 is summed up in the new LEVIFLEX SERIES, which takes its name from the Latin “levis”, meaning light. LEVIFLEX Series membranes are suitable for most of the applications required by today’s market. LEVIFLEX 20, LEVIFLEX 15, LEVIFLEX 10 and LEVIFLEX ARD 20, 15, 10 membranes are produced using a continuous filament polyester fabric reinforcing mat with lengthwise mineral fibers. This reinforcing mat ensures that LEVIFLEX membranes provide outstanding dimensional stability and performance, completely eliminating membrane pullaway at both end laps and side laps.
