PART 3

EXECUTION

3.1

EXAMINATION

Do not begin installation until substrates including framing/sheathing, vapor barriers, ventilation and moisture control have been properly prepared in accordance with the siding manufacturer's requirements.

If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.

3.2

PREPARATION

Coordinate work with related trades; scribe and cope siding boards for accurate fit. Allow for installation of related work to avoid cutting and patching.

Do not apply siding to a rain soaked structure. Do not apply siding that is wet.

Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.

3.3

INSTALLATION

Install in accordance with manufacturer's printed installation instructions for the products specified.

Install siding panels by attaching to solid nailable sheathing, spaced nailable sheathing or to studs spaced not exceeding 16 inches O.C..

Gaps, Clearances, and Corners:

Leave 3/16 inch gap at all butt joints, around all doors and window frames, and at joints in the soffits for all lap and square edge siding products. Caulk all gaps.

Gap the siding at all corners 3/16 inch and caulk.

Siding must have a minimum 2 inch separation from concrete or be appropriately flashed. Siding must be 6 inches from soil or landscaping material.

Where the siding meets the roof, it must be spaced a minimum of 2 inches from the plane of the roof and be properly flashed. Cut edge must be primed and painted.

Shiplap and Square Edge Panels: Examine the framed structure to determine the positioning of the studs in relation to the exterior corners, windows and door openings. Plan for areas that do not allow installation of the full panel.

From the pre-selected starting position, place a panel square on the wall with the bottom edge level. All nailing edges must be positioned over studs. When positioning the next panel, do not force the panel into place. If installing a shiplap panel, place overlap edge on top of underlap edge prior to nailing.

For shiplap edge panels, there should be a 1/16 inch gap between the underlap edge and the next panel. Do not force the edge of the panel over this ridge.

For square edge panels, there must be 3/16 inch gap at the vertical joint. This gap must be caulked; it is recommended to cover the joint with a wood batten nailed 12 inches o.c.. TruWood Trim is recommended for batten material.

Follow siding manufacturer's fastening schedule and nail panels 1/2 inch to 5/8 inch from vertical edges

At corners, use TruWood Trim. Make sure all gaps are caulked.

At butt joints around windows and doors, a 3/16 inch gap is required and must be caulked.

At horizontal joints with stacked panels or other types of siding, overlap siding 1 inch or use metal Z flashing.

Standard Lap and Self-Aligning Lap Siding: Start application by nailing a starter strip, approximately 1-1/2 inches wide, aligned with the bottom edge of the sill plate. Level and install the first course of siding so its lower edge is 1/8 inch to 1/2 inch below the starter strip.

For Standard Lap products overlap successive courses at least 1 inch.

For Self-Aligning Lap Sidings place the self-aligning lap edge on the top of each additional course; make sure the self-aligning lap joint is resting flat on the lower piece.

Nail lap products 5/8 inch to 3/4 inch above the drip edge. Be sure nails penetrate through both pieces of siding and into studs.

Periodic checks are necessary to assure the lap remains level. Make adjustments as necessary.

Vertical butt joints must be located only on studs. Each piece of siding must be nailed top and bottom to studs.

When butting siding to inside or outside corners, use a minimum 4/4 inch thick (nominal) dry wood material. TruWood Trim is recommended.

Designer Shake Lap Siding: Unless being applied above other siding, as in a gable area, a shim and starter strip are required. Start application by nailing a shim approximately 1-1/2 inch wide and 1/8 inch to 1/4 inch thick level with the bottom edge of the foundation sill plate.

Starter strip should be 4 to 5 inches wide, 1/2 inch thick and be installed to hang below shim approximately 1 inch. If desired, the starter strip can be cut from Designer Shake and the bottom half of the lap used for the top course.

The indentations profile cut outs of the bottom edge of the Designer Shake must overlap the top of the starter strip at least 1 inch. If applied above other siding, the indentation should also cover by 1 inch.

Depending on the particular profile, maximum exposure varies from 4-1/4 inches for the Diamond pattern to 7-1/2 inches for the Fishscale pattern.

Periodic checks are necessary to assure the horizontal lap remains level. Make adjustments as necessary.

Vertical butt joints must be located only on studs. Each piece of siding must be nailed top and bottom to studs.

Stagger alternating courses one-half of the repeating pattern for design appeal. This may require trimming of one piece to align with studs 16 inches o.c.

Nails should be placed no closer than 5/8 inch from any edge. Nails should penetrate both courses and be nailed both top and bottom on each side of the butt joint.

When butting siding to inside or outside corners, use a minimum 4/4 inch thick (nominal) dry wood material. TruWood Trim is recommended.

Fastening:

Use corrosion resistant 8d boxhead nails with a minimum head diameter of 1/4 inch.

All panel products require that both vertical and horizontal joints be located on framing and nailed in accordance with the manufacturer's fastening schedule.

Nails must penetrate wood framing 1-1/2 inches. Avoid counter sinking nails or rupturing the surface of the siding.

If countersink occurs, caulk nail prior to painting.

Fasten panels from end to end or center to end to avoid internal stress.

Finish paint within 90 days after installation as specified in Section 09900. If siding is exposed for a longer period, reprime the siding with a high quality oil or alkyd-based primer.

3.4
