Boral TruExterior Beadboard is tongue and groove, allowing it to be installed with a fastener through the tongue so the aesthetic is free of visible fasteners. The beadboard looks like traditional wood beadboard and is reversible to provide the option for a “v-groove” appearance in addition to the “edge and center bead” profile. Dimensional stability allows the beadboard to be installed parallel to the house. Additionally, it can span 24-in. without the need for additional backing or added support.
