Hydro Board Shield is a roll-form waterproofing membrane used as a moisture barrier over roof decks, sheathing and other board substrates. It is supplied in a single continuous roll so a run can be laid out and lapped without cutting more seams than necessary.

Sheet membranes of this class work by shedding and blocking liquid water at the face of the substrate, keeping the board beneath it dry while the finished roofing or cladding is installed over top. Courses are rolled out, aligned, and overlapped at the side and end laps so water always drains over a seam rather than into it.

Because the material comes as a flexible sheet, it can be worked over plane changes, valleys and around penetrations where a rigid product cannot follow the substrate. Fastening or adhering method, lap widths and exposure limits should follow the manufacturer's printed installation instructions for this product.

Key Features

• Supplied as a single continuous roll for full-length runs with fewer seams
• Flexible sheet membrane that conforms to plane changes, valleys and penetrations
• Forms a water-shedding layer between the structural substrate and the finished cladding or roofing
• Installed in lapped courses so water drains over the seam rather than into it
• Roll width suited to coursing across sheathing and deck panels
• Sold by the roll, so coverage is calculated by run length rather than by piece

Applications

• Moisture protection over roof deck sheathing beneath the finished roofing
• Underlayment layer on board and panel substrates
• Waterproofing at valleys, transitions and other water-collecting details
• Protection of sheathing during the construction sequence prior to cladding
• Lapped membrane coverage on low-slope and sloped roof areas where permitted by the manufacturer's instructions
