MoistureShield makes wood-composite decking and railing, manufactured from 95% recycled content and engineered to be installed on the ground, in the ground or underwater without the structural failures that affect ordinary wood decking. Oldcastle APG, a CRH company, had acquired the business as Advanced Environmental Recycling Technologies (AERT) and renamed it MoistureShield on 13 May 2019 to align it with the rest of its outdoor-living portfolio. Product lines sold under the name include Vision, Infuse and Vantage decking, along with hidden-fastener and joist-tape accessories.
CRH is a publicly listed company headquartered in Dublin, Ireland, founded in 1970. Brandtree records 8 brands under its control, and it is listed as NYSE: CRH and LSE: CRH.

Oldcastle Architectural, Inc. (part of CRH’s Oldcastle APG business) agreed on 16 March 2017 to acquire Advanced Environmental Recycling Technologies, Inc. (AERT), a Nasdaq-listed maker of composite decking, in an all-cash merger at an enterprise value of $117 million as stated in AERT’s SEC information statement; the cash paid to holders was calculated by subtracting AERT’s net debt and transaction expenses from that figure, working out to $0.135936 per common share and $2,603.483278 per preferred share. A merger subsidiary of Oldcastle Architectural merged into AERT on 1 May 2017, making AERT a wholly owned subsidiary of Oldcastle Architectural, per AERT’s Form 8-K filed that day. This is the actual acquisition behind the brand: two years later, in May 2019, Oldcastle APG renamed the acquired composite-decking business from AERT to MoistureShield, which was a rebranding rather than a separate transaction and is not recorded as its own deal. Oldcastle APG is a CRH operating business rather than a separate legal entity in this dataset, so the buyer is recorded as CRH.
The parent company of MoistureShield is CRH, a publicly listed company headquartered in Ireland.
