respirant

CONT: L'enduction Witcoflex [...] composée de polyuréthane hydrophile, transmet la vapeur d'eau par action moléculaire, permettant d'obtenir un tissu enduit à la fois imperméable à l'eau et respirant. [...] le Witcoflex Superdry possède un fort pouvoir respirant, c'est-à-dire une perméabilité élevée à la vapeur d'eau associée à un toucher doux.

CONT: Breatheable: of a fabric, etc., allowing air to pass through.
CONT: The Witcoflex coating ... is a hydrophilic polyurethane which transmits vapour by molecular action thus making a coated fabric both breathable and waterproof Witcoflex Superdry ... offers an improved breathability combining high moisture vapour permeability with a soft handle.
CONT: Supported by calculations and field data, it is concluded that IAQ [Indoor Air Quality] can be greatly improved by using a holistic approach to building design. Breathing walls made of vapour permeable and highly hygroscopic materials, such as Durisol and strawbales, can enhance IAQ when used in conjunction with other strategies.
