    Can I paint AdvanTech® subflooring and sheathing panels?

    AdvanTech panels can be left natural, stained, varnished or painted with oil- or epoxy-based paints, or oil-based primer and latex paint. Water seal is not recommended. AdvanTech panels are not recommended for exterior siding or other applications that are permanently exposed to the weather.

    There are loose strands on some panels. Is this a problem?

    Although rare, sometimes a few strands do not get fully coated with resin during the blending process. Since there is little resin holding the strand to the board, exposure to moisture or some other external influence will cause the strand to release. This normally affects the surface of the panel and rarely extends into the board deeper than one or two strands. Loose strands may require some additional sanding and possibly filling prior to finish floor application, but this is so minor that it will generally not affect the strength of the product.

    Can a tongue and groove subfloor panel be used in a roof application?

    Yes, a common misconception is T and G flooring panels (Floor Span) cannot be used for roofing applications. Table 2 in ER-5637 NER-133 lists allowable live loads for Floor Span panels used for roofing applications. It should be noted that sheathing panels (Sheathing Span) used for roofing applications have different design capacities than Floor Span panels. Note: Flooring panels are sanded and may not provide adequate slip resistance.

    Do I need to use H-clips with my roof sheathing?

    In order for the maximum span rating to be used for sheathing panels 3/8" thick, 15/32" thick and thicker, edge support must be used for unsupported edges. Edge support includes T and G edges, panel clips or lumber blocking. That being said, H-clips are not required for sheathing panels with a T&G edge profile. If panel clips are used for edge support, one between each support is sufficient. If supports are at 48" o.c., then 2 clips between supports are needed. Some, but not all, panel clips have out-dents to provide the recommended 1/8" gap at edges. Although panel clips are not always needed, some code jurisdictions require their use. Check with the local building department in your area for any panel clip requirements.

    How should I fasten AdvanTech panels?

    FLOORING INSTALLATION: Glue with nails or screws should be used to ensure greater floor stiffness. Gluing helps eliminate nail-popping and floor squeaks. Huber Engineered Woods recommends using polyurethane or solvent-based adhesives that conform to industry standard APA AFG-01 or ASTM D 3498; follow manufacturer's recommendations. Before each panel is placed, a line of adhesive should be applied to the top of the joist. A min. 1/4" bead of glue is recommended. Fasteners should penetrate framing members at least 1". Apply fasteners 3/8" from panel edges. Space fasteners 6" o.c. on supported edges (4' ends) and 12" o.c. at intermediate support locations. Ensure that all corners are securely fastened. Note: 1-1/8" panels spaced 48" o.c. should be fastened 6" o.c. at intermediate support locations. Use 8d ring shank nails, screw shank nails or #8 wood screws for panels up to ¾” thick and 10d ring shank nails, screw shank nails or #9 wood screws for panels thicker than ¾”.

    SHEATHING INSTALLATION: Use minimum 6d common nails for panels 1/2" or less. Use minimum 8d common nails for panels 5/8" to 1". Other code-approved fasteners may be used when roof construction is not required to meet diaphragm or shearwall strength criteria complying with HUD/FHA UM 25d. Apply fasteners 3/8" from panel edges. Space fasteners 6" o.c. along supported edges, 12" o.c. at intermediate supports. Ensure that all corners are securely fastened. For 48" o.c., all fastener spacing should be 6" o.c. Check local code provisions for high wind areas. Note: AdvanTech sheathing is not recommended for residential siding.

    I just installed an AdvanTech® subfloor, and it's now raining heavily. What's going to happen?

     

    AdvanTech panels are manufactured with a highly moisture resistant resin and are guaranteed not to require sanding due to moisture absorption[1]. With other OSB commodity products, a certain amount of edge swelling can be expected when subject to direct exposure to moisture. Once the structure is enclosed and the panels are acclimated, any joints that have swollen can be sanded to provide a smooth surface for the finished floor covering. The Huber Engineered Woods no-sand guarantee extends up to 500 days after installation1. See warranty for details.
