Critical Installation Rules

1. 1

   Never face-nail siding — always fasten through the nailing hem only

2. 2

   Allow a minimum of 1/32" space between the back of the fastener head and the nailing hem — panels must move freely side to side

3. 3

   Space fasteners 12" to 16" apart on center

4. 4

   Center fasteners in nail slots — fastening at the end of a slot will cause permanent damage; use a nail-slot punch to lengthen slots if needed

5. 5

   Drive fasteners straight and level — nailing at an angle distorts panels and causes buckling

6. 6

   Leave 1/4" expansion gap at all openings and accessory channel stops (increase to 3/8" in temperatures below 40°F)

7. 7

   Do not caulk between panels, between siding and J-channel, or between siding and corner trim — panels must expand and contract freely

8. 8

   When installing a panel, push up from the bottom until the lock is fully engaged with the piece below, then fasten without stretching

9. 9

   When finishing top of wall, perforate cut edge with snap-lock punch approximately every 8" so tabs face outward

10. 10

    Overlap horizontal siding panels approximately 1" — excessive overlap restricts free movement and can cause product failure

11. 11

    Stagger end lap joints so no two courses are vertically aligned unless separated by at least 3 courses

12. 12

    Always overlap joints away from entrances and away from the point of greatest traffic

13. 13

    Check every fifth or sixth course for horizontal alignment; also check alignment with adjoining walls

14. 14

    Use fasteners long enough to penetrate a minimum of 3/4" into the nailable base

15. 15

    Install starter trim level — it sets the alignment for all subsequent courses; nail at 10" intervals

16. 16

    Keep starter strip ends at least 1/4" apart from corner posts and J-channels to allow for expansion

17. 17

    Apply undersill trim under all windows; use snap-lock punch on cut panel edges every 6" for secure fit

18. 18

    Apply drip cap above all windows and doors before installing siding over them

19. 19

    Do not install over foil-back foam insulation — voids Kaycan warranty

20. 20

    Asbestos siding is a regulated material — contact the appropriate environmental agency before residing over it

21. 21

    Check all local building codes and fire regulations before installation; local code requirements always take precedence

22. 22

    In new construction, avoid green lumber as underlayment — siding can only be as straight as what lies beneath it

Fastener Requirements

Accessory Applications

Estimating & Ordering

1. 1

   Step 1 — Sketch all four sides of the home; for each wall multiply height × width to get surface area in sq.ft.

2. 2

   Step 2 — Measure gables and dormers: for each triangle measure straight up from the base to the top, then multiply base × height × 0.5; add all gable/dormer areas together

3. 3

   Step 3 — Measure all openings NOT to be covered (windows, doors, chimneys) and multiply height × width for each; add together

4. 4

   Step 4 — Add Step 1 + Step 2, subtract Step 3, then add 10% for cutting waste: Siding required = [Step 1 + Step 2 − Step 3] + 10%

5. 5

   Step 5 — Divide total sq.ft. by 100 to determine the number of squares needed; round up to next whole square

6. 6

   Step 6 — Measure under eaves: multiply the length by the width of each overhang and add together (for soffit calculation)

7. 7

   Step 7 — Determine soffit squares: divide soffit total from Step 6 by 100

8. 8

   Step 8 — Measure linear feet of each accessory (starter strip, J-trim, corner posts, drip cap, undersill trim)

9. 9

   Step 9 — Convert sq.ft. to boxes: divide by coverage per box (200 sq.ft. for D4/D5 profiles, 198 sq.ft. for D4.5/T3 profiles)

Storage & Handling

• Store cartons flat on a level surface, supported along their full length
• Keep cartons dry and away from rain and prolonged direct sunlight
• Store away from areas where falling objects or construction activity may cause damage
• Maximum stacking height: 6 boxes high — ensure stacks are stable
• Maximum storage temperature: 130°F / 54.4°C (avoid blacktop pavement in summer, dark tarps without air circulation)
• Do not drag bundles — carry or use a panel carrier to avoid scratching and distortion
