Natural Style and Endurance
Kaycan Prova™ brings unparalleled beauty and distinctive style to vinyl lap siding. The Double 4.5" Dutch lap profile delivers deep, rich shadow lines that create natural depth and dimension, while a realistic wood grain texture and low-gloss finish ensure authentic curb appeal. Colour is infused throughout the panel — so it won't chip or fade even at cut edges. Exclusive Duratron™ Vinyl Technology ensures long-term weatherability in Canadian conditions. Available in 19 colours across Ontario, Quebec, and the Atlantic provinces.

Double 4-1/2" Dutch lap panel with 3/8" profile depth and realistic woodgrain texture — delivers deep, rich shadow lines for a natural, dimensional appearance
| Length | 12' (3.66 m) |
| Panels/Box | 22 panels/carton |
| Coverage | 198 sq. ft. (18.39 m²) per carton |
| Gauge | 0.048" |
| Profile Depth | 3/8" |
Never face-nail siding — always fasten through the nailing hem only
Leave 1/32" clearance between fastener head and nailing hem (panels must move freely)
Leave 1/4" expansion gap at all openings, corners, and trim junctions — increase to 3/8" in cold climates or below 40°F
Do not caulk between panels, between siding and J-channel, or between siding and corner trim — panels must expand and contract freely
When installing a panel, push up from the bottom until the lock is fully engaged with the piece below, then fasten without stretching
Drive fasteners straight and level — nailing at an angle distorts panels and causes buckling
When finishing top of wall, perforate cut edge with snap-lock punch approximately every 8" so tabs face outward
Overlap horizontal siding panels approximately 1" — excessive overlap restricts free movement and can cause product failure
Stagger end lap joints so no two courses are vertically aligned unless separated by at least 3 courses
Always overlap joints away from entrances and away from the point of greatest traffic
Check every fifth or sixth course for horizontal alignment; also check alignment with adjoining walls
Use fasteners long enough to penetrate a minimum of 3/4" into the nailable base
Install starter trim level — it sets the alignment for all subsequent courses; nail at 10" intervals
Keep starter strip ends at least 1/4" apart from corner posts and J-channels to allow for expansion
Apply drip cap above all windows and doors before installing siding over them
Check all local building codes and fire regulations before installation; local code requirements always take precedence
In new construction, avoid green lumber as underlayment — siding can only be as straight as what lies beneath it
General Tools
Specialty Tools
| Accessory | Purpose | Where to use |
|---|---|---|
| Kaylok Steel Starter Trim (108300)2-1/2" steel starter with Kaylok system — provides solid base and resists wind lift at the base course | First course anchor — sets the angle and alignment for the entire installation | Bottom of wall, level, 1" above finished grade or above foundation; nail at 10" intervals |
| 5/8" J Trim (1035)5/8" deep channel designed for Prova's 3/8" profile depth; accommodates panel movement at all opening perimeters | Frames doors, windows, and other wall penetrations | Around door and window openings — sides and top |
| H Trim (1179)5/8" channels on both sides receive adjacent panel ends — provides a clean finished seam without visible laps | Joins siding panels end-to-end on long horizontal runs without overlapping | At vertical seams where two panel ends meet mid-wall; keep seams staggered between courses |
| Undersill Trim (1066)Snap-lock profile grips cut panel edges — eliminates need for snap-lock punch at undersill locations | Locks cut panel edges under windowsills and horizontal trim | Under window sills and beneath any horizontal trim band |
| Drip Cap (1185)2" height; install before siding — siding laps over drip cap flange to ensure proper drainage | Directs water away from door and window tops, preventing moisture infiltration | Above all windows and doors before installing siding over them |
| Inside Corner (1115)3/4" channel depth — accepts Prova panels at inside wall intersections for a clean, weathertight finish | Finished inside corners where two walls meet at an interior angle | Plumb at inside corners; panels slide into 3/4" channels on each side |
Formula
Siding required = [Wall area (Step 1) + Gable/dormer area (Step 2) − Openings area (Step 3)] + 10% waste
1 square = 100 sq.ft. (standard industry unit); Prova carton covers 198 sq.ft. (1.98 squares)
Step 1 — Sketch all four sides of the home; for each wall multiply height × width to get surface area in sq.ft.
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
Step 3 — Measure all openings NOT to be covered (windows, doors, chimneys) and multiply height × width for each; add together
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%
Step 5 — Divide total sq.ft. by 198 to determine the number of cartons needed (1 carton = 198 sq.ft.); round up to next whole carton
Step 6 — Measure under eaves: multiply the length by the width of each overhang and add together (for soffit calculation)
Step 7 — Determine soffit squares: divide soffit total from Step 6 by 100
Step 8 — Measure linear feet of each accessory (starter trim, J-trim, H trim, undersill trim, drip cap, inside corners)
Step 9 — Order accessories: starter trim by linear feet (10' lengths); J-trim and H trim by linear feet (12' lengths); inside corners by linear feet (10' lengths)
Colour is manufactured throughout the panel — scratches or cut edges are not visible from normal viewing distance
