THE NAILER- DRYWALL backerS FOR SUPPORTING INTERIOR DRYWALL CORNERS- GALVANIZED STEEL OR RECYCLED PLASTIC
Guidance for designers and specifiers, with suggested language to be modified and incorporated into project’s specifications

PART 1 - GENERAL

1.01 WORK INCLUDED

A. Work under this section comprises the use of THE NAILER in galvanized steel or 100% recycled plastic as a drywall backer for supporting interior drywall corners, See Gypsum Wallboard Work as indicated by the Contract Documents.

THE NAILER is designed to support gypsum wallboard at wall corners and wall ceiling intersections. The backers replace conventional non-structural, non-load bearing backup studs or blocking used to provide support at such locations. They also replace drywall clips that are clasped on to the drywall with sharp metal tabs that may cause safety issues. THE NAILER is hard fastened to both the drywall and the support, whether it iswood or metal.

The metal NAILER is formed from No. 19 (.039”) gauge galvanized steel into a T-shaped section living an overall depth of 2 inches. THE NAILER is 1 ½” in width and can be used to secure two sheets of drywall where they meet at a seam in similar fashion to the joining of two sheets on a 1 1/2” stud or ceiling joist.

The planar member used for fastening/support of the drywall is 1 3/8” in length and has an anti-skating grid surface to prevent screws from slipping across the surface. A 5/8” backtab coupled with a ¼” ridge running the entire length of the backslide provides extra support in addition to securing the downstem.

The plastic NAILER is made from #2 High Density Polyethylene (HDPE), 100% recycled plastic.Due to the recycled nature of the raw n\material it is produced in a wide array of different colors. To maintain the 100% recycled claim, the manufacturer has elected not to introduce an artificial additive for color uniformity.

The metal NAILER may be used in residential, commercial and multiple housing constructions. The 100% recycled plastic NAILER is approved for residential construction.

1.03 SUBMITTALS

A. INCLUDE IF PROJECT REQUIRES RECYCLED CONTENT DOCUMENTATION, SUCH AS FOR LEED RECYCLED CONTENT CREDITS(S) Submit invoices and documentation from manufacturer of the amounts of post-consumer and post-industrial recycled content by weight for products with specified recycled content.

The plastic NAILER is made from #2 High Density Polyethylene (HDPE), 100% recycled plastic. The metal NAILER is made from N0. 19 gauge (.039”) galvanized steel.

1.04 QUALITY INSURANCE

A. Single-Source Responsibility: Obtain THE NAILER drywall backer from the manufacturer or from one of their distributors. THE NAILER is the only patented drywall backer that hard fastens to both the drywall and the framing and the product should be marked with U.S. Patent No.5,581,964.

PART 2- PRODUCTS

2.01 MATERIALS

A. For home construction use either the plastic or galvanized steel NAILER.

B. For commercial construction use the galvanized steel NAILER.

PART 3- EXECUTION

3.01 INSPECTION

A.        Inspect framing to receive drywall for accurate spacing, alignment and plumb. Report any unsatisfactory conditions to the General Contractor.

B.         Verify that spacing of installed framing does not exceed maximum allowable for thickness of gypsum board to be used.

C.        Do not proceed with installation of THE NAILER drywall backers until deficiencies are corrected and surfaces to receive gypsum board are acceptable.

D.        Protrusions of framing, twisted framing members, or unaligned members shall be repaired before installation of drywall backers is started.

E.         Acceptance: Beginning of installation of NAILERS indicates acceptance of framing.

3.02 INSTALLATION

A.        Identify any interior wall and/or ceiling corner. Do not install wood blocking.

B.         Starting at one end of the wall, staple, nail or screw THE NAILER above every stud 16” on center. The plastic NAILER can be attached with a minimum of two ½” staples, a nail or a screw. The galvanized steel NAILER is attached with a Tex Screw on both wood and steel framing.

C.        Screw wallboard into NAILER tab.

D.        To float corners follow Gypsum Association Specifications in GA-216     2004 4.90 through 4.95 as follows:

4.9 Floating Interior Angles

4.9.1 The floating angle method of application shall be permitted to be used to minimize the effects of truss uplift and the possibility of backer popping in areas adjacent to wall and ceiling intersections. This method is applicable where either single nailing, double nailing, or screw attachment to wood framing is used.

4.9.2 Ceiling-Wall Intersections.

4.9.2.1 The first backer into each ceiling framing member, framed either perpendicular or parallel to the wall, shall be located not more than 7 in. (178 mm) out from the intersection for single nailing and not more than 12 in. (305 mm) for either double nailing or screw application.

4.9.2.2 The gypsum panel products on the wall shall be applied to provide firm support for the floated edges of the gypsum panel product on the ceiling. The uppermost backer into each stud shall be located not more than 8 in. (203 mm) down from the ceiling intersection for single nailing and not more than 12 in. (305 mm) for either double nailing or screw application.

4.9.3 Inside Corners of Walls.

4.9.3.1 The overlapping gypsum panel product shall be applied so as to bring the back of the underlying gypsum panel product into firm contact with the face of the framing member behind it.

4.9.4 Special clips designed to provide support at wall corners and wall-ceiling intersections in lieu of back-up studs or blocking shall be permitted where approved.

4.9.5 Floating interior angles shall not be used where fire ratings are required.
