The 1\/4 in. mat is the safer choice behind thick cladding like brick or stucco systems; .125 in. is adequate for many lap-siding assemblies. Run courses with shingled laps so water always drains outward, and seal penetrations as you go.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eFollow the siding manufacturer's installation instructions and local building codes for drainage requirements behind cladding.\u003c\/em\u003e\u003c\/p\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003eOrder the Mortairvent Rainscreen Drainage Mat in the thickness your wall assembly calls for.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Mortairvent","offers":[{"title":"39\" x 61-1\/2' x .125\" \/ SQ (price per square)","offer_id":53524665663855,"sku":"ADVMORTAIR10","price":153.78,"currency_code":"USD","in_stock":true},{"title":"39\" x 61-1\/2' x 1\/4\" \/ RL","offer_id":53524665696623,"sku":"ADVMORTAIRPS","price":191.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/3499\/7051\/files\/ADVMORTAIR10_0.jpg?v=1790285021","url":"https:\/\/superarbor.io\/products\/mortairvent-rainscreen-drainage-mat-39-in-x-61-1-2-ft-roll","provider":"Super Arbor","version":"1.0","type":"link"}
