Tongue and groove clear cedar 1/2 x 4 measures 1/2″ x 3 1/2″. This wood is as nice as it gets but because of minor defect can not be sold as top grade and price. If you can work with it by using 1 side or sanding or cutting into smaller pieces you will save a bunch. People use for saunas but also for projects like patio planter boxes. Shorter lengths available – 2′ – 7′.
