4.

WMC: Water Management Clips are factory applied to the lap siding components and are spaced every 16 inches. The WMC spaces the siding away from the house-wrap to create the water management drainage and back ventilation plane.

5.

Seam Flashing: Molded component centered behind the ends of two adjacent siding pieces used for support, alignment, flashing water and maintaining the water management plane.

6.

AWB (Air and Water Barrier) (Air/Water Barrier): Wall System layer(s) that limits the transfer of liquid water and air through the system.

PART 3 – EXECUTION

3.01 EXAMINATION

A.

Do not begin installation until substrates (AWB, sheathing, framing) have been properly prepared. Correct any conditions detrimental to proper installation.

B.

Do not install over inadequate structural framing. Do not install over buckled or wet materials.

Do not install if excessive moisture is present due to curing concrete on the interior.

C.

Removal of any prior siding is highly recommended.

3.02

INSTALLATION

A.

Apply all APEX siding system components in strict accordance with manufacturer’s installation instructions and all pertinent building codes.

B.

Read warranty and comply with all terms to maintain warranty coverage.

C.

Flash all wall openings in accordance with all pertinent building codes and best practice methods.

D.

Install trim, with trim caps, level and plumb.

E.

Install starter strip level and fasten through water management clips (WMC) and a minimum of

1” into studs or solid backing.

F.

Install APEX siding and trim:

1. Install siding for natural watershed, WMC must be used on starter strip and all lap siding to maintain the drainage and ventilation plane. Follow local building codes for minimum clearance of adjacent grade. Apex has no limitation.

2. Align level and plumb. Locate cut siding edges and ends over studs. For visual quality, siding to siding and siding to trim joints should abut.

3. Fasten siding as recommended by manufacturer’s instruction, through WMC and a minimum of 1” into studs or solid backing.

4. Place manufacturer’s seam flashing behind all joints.

5. Use manufacturer supplied installation tool to distribute impact around WMC when fastening through a soft substrate like foam.

G.

When properly installed over a code compliant air and water barrier, APEX Siding System does not require caulking at seams or end joints. If caulk is used, chose one that is paintable.

3.03

SITE QUALITY CONTROL

A.

Protect installed products until completion of the project.

B.

Repair or replace damaged products.
