news newspapers books scholar jstor february 2026 learn how and when to remove this message air barriers control air leakage into and out of the building envelope air barrier products may take several forms mechanically attached membranes also known as housewraps usually a polyethylene fiber or spun bonded polyolefin such as tyvek is a generally accepted moisture barrier and an air barrier astm e2178 self adhered membranes which are typically also a water resistant barrier and a vapor barrier fluid applied membranes such as heavy bodied paints or coatings including polymeric based and asphaltic based materials closed cell medium density spray applied polyurethane foam which typically provides insulation as well boardstock which includes 12 mm plywood or osb 25 mm extruded polystyrene etc some open cell spray applied polyurethane foam that are of high density components edit air barriers are divided into air barrier materials air barrier accessories air barrier components air barrier assemblies and air barrier systems air barrier materials building materials that are designed and constructed to provide the principal plane of airtightness through an environmental separator which has an air permeance rate no greater than 0 02 l s m 2 at a pressure difference of 75 pa when tested in accordance with astm e 2178 air barrier materials meet the requirements of the can ulc s741 air barrier material specification the air barrier materials are typically the big pieces of material used in an air barrier assembly 1 air barrier accessories products designated to maintain air tightness between air barrier materials assemblies and components to fasten them to the structure of the building or both e g sealants tapes backer rods transition membranes nails washers ties clips staples strapping primers and which has an air permeance rate no greater than 0 02 l s m 2 at a pressure difference of 75 pa when tested in accordance with astm e 2178 air barrier components are used to connect and seal air barrier materials and or air barrier assemblies together 1 air barrier components pre manufactured elements such as windows doors and service elements that are installed in the environmental separator and sealed by air barrier accessories and which have an air leakage rate no greater than 0 20 l s m 2 at a pressure difference of 75 pa when tested in accordance with astm e 2357 1 air barrier assemblies combinations of air barrier materials and air barrier accessories that are designated and designed within the environmental separator to act as a continuous barrier to the movement of air through the environmental separator and which has an air leakage rate no greater than 0 20 l s m 2 at a pressure difference of 75 pa when tested in accordance with astm e 2357 1 air barrier systems combinations of air barrier assemblies and air barrier components connected by air barrier accessories that are designed to provide a continuous barrier to the movement of air through an environmental separator which has an air leakage rate no greater than 2 00 l s m 2 at a pressure difference of 75 pa when tested in accordance with astm e 779 or can cgsb 149 10 or can cgsb 149 15 1 vapor barrier edit some air barriers may be water vapor permeable while others perform the function of a vapor barrier 2 they may be vapor permeable
