Kaycan Montebello™ Insulated Log Siding

Critical Installation Rules

1. 1

   Install starter trim level — determine the lowest point of the wall, measure up 1/4" less than the width of the starter, drive a nail at one corner, then attach and pull a chalkline; verify the line is level using a line level or 4-foot level before snapping

2. 2

   Snap the chalkline and repeat the procedure around the entire house; install the Kaylok Steel Starter Trim along the bottom of the chalkline, nailing every 10" in the center of the slots

3. 3

   Keep the ends of starter strips at least 1/4" apart to allow for expansion; leave approximately 1/4" between the starter and the corner post

4. 4

   Flash the inside and outside of all corners with a water-resistant barrier, minimum 10" on each side, before installing corner posts

5. 5

   Place the corner post with a 1/4" gap between the top of the post and the eave or soffit; position the first nail at the top of the upper slot on both sides — the corner post hangs from these nails

6. 6

   All remaining corner post nails go in the center of the slot, 8" to 12" apart; leave 1/32" clearance between nail head and corner post; corner post must extend 3/4" below the starter strip and must be plumb; for a better finished appearance, remove a 3/4" portion of the nail hem on both sides of the corner post

7. 7

   For inside corners, two 1-1/4" J-channels must be used — follow the same installation procedure as for outside corner posts, with two J-channels installed face-to-face as shown in the Kaycan Vinyl Siding Estimating and Installation Guide

8. 8

   Install 1-1/4" J-channels (VJB1251F) along windows and walls not requiring corner posts; follow J-channel installation instructions in the Kaycan Vinyl Siding Estimating and Installation Guide

9. 9

   Place the first Montebello panel into the Kaylok Steel Starter Trim and slide it into the corner post pocket; fasten panels in the center of the nailing slots

10. 10

    Allow 1/4" clearance between siding and all channels and J-trim; increase to 3/8" when installing in temperatures below 40°F (4°C)

11. 11

    Leave 1/32" (approximately the thickness of a dime) between the fastener head and the nail slot — do not overtighten fasteners

12. 12

    Do not force the panel up or down when fastening; panel locks should be fully engaged but panels must not be under vertical tension or compression when fastened

13. 13

    Once fastened, vinyl panels can move freely in a side-to-side direction as temperatures change — verify panels float freely before moving to the next course

14. 14

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

15. 15

    When panels overlap at joints, overlap by half the length of the end notch (approximately 1"); ensure the foam inserts in the back of the panels are touching at each joint

16. 16

    Always overlap panel joints away from entrances and away from the point of greatest traffic; stagger siding seams so they are at least three courses apart

17. 17

    When cutting the panel above a window or under the crown: cut to length, punch snap locks every 6" to 8", then push the panel securely into the 1-1/4" J-channel; if cutting above the foam section, use a 5/8" J-channel instead and snap-lock accordingly

18. 18

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

19. 19

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

20. 20

    Installation instructions must be followed — any deviation will render the warranty null and void

21. 21

    Always refer to the complete Kaycan Vinyl Siding Estimating and Installation Guide before starting

22. 22

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

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.; add all wall areas together

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, then subtract Step 3: Total area = [Step 1 + Step 2 − Step 3]

5. 5

   Step 5 — Divide total sq.ft. by 100 to determine the number of cartons needed (1 carton = 100 sq.ft.); round up to next whole carton — rounding up eliminates the need for a separate waste factor

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 (J-trim, corner posts, starter trim)

9. 9

   Step 9 — Order accessories: J-trim by linear feet (12' lengths); corners by linear feet (10' lengths); Kaylok Starter Trim by linear feet (10' lengths)

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
