Versetta Stone vs NovikStone: One Is Nailed Tight, One Is Not

September 21, 202619 min readLena Marchetti · Stone Veneer & Specialty Cladding Advisor

Key points

  • Versetta Stone lands on the wall at 8.5 lb per square foot, roughly eleven times a Novik stone panel at 0.75
  • The CCMC evaluation that covers NovikStone in Canada only covers it on furring with a 10 to 19 mm air space behind it
  • A Versetta Stone warranty transferred to a second owner stops at 15 years, not 50

Cement or Plastic: Versetta Stone and NovikStone Compared

Two walls on the same street in Aurora can carry stone that reads identically from the sidewalk and behaves nothing alike behind the face. One is Versetta Stone, a cement panel with a steel nail strip cast into its top edge. The other is a Novik stone panel, a moulded polypropylene shell with a slotted nailing channel. Neither needs a mason, mortar or lath, which is most of why faux stone panels took so much of the veneer market across the GTA. Both hang on a nail.

That is where it stops. One of those nails is driven tight and is never meant to move again. The other is driven deliberately short, into the middle of a slot, and the system fails if it is driven home. Every other difference between the two on a job site follows from that one: the sheathing under them, the strapping behind them, the weight on the wall, the number of fasteners a crew puts in per hour, and the paperwork you hand an Ontario building official.

What Is Versetta Stone, and What Is a Novik Stone Panel?

Versetta Stone is a precast glass fibre reinforced cement panel, 8 by 36 inches exposed and 17 pounds, with a G90 galvanized steel nail flange moulded into its top edge. A Novik stone panel is an injection moulded polypropylene shell, 2.03 to 3.18 mm thick, with a slotted nailing channel. Both fasten with nails or screws and neither uses mortar.

Watch: the one sentence from each installation guide, the same 100 sq ft wall tiled with both panels at true scale, and what the CCMC evaluation actually requires behind a Novik wall.

The materials are not cousins. Versetta Stone is portland cement, glass fibres and mineral oxide pigment, cast in moulds taken off natural ledgestone and tight cut limestone, and its ICC evaluation report ESR-2859 files it under glass fibre reinforced cementitious panels. It is made by Westlake Royal and reaches us through Kaycan. Novik stone panels are made by Derby Building Products in Saint-Augustin-de-Desmaures, Quebec, out of the same polypropylene family that runs through the rest of the Novik shake and brick range.

What they share is the delivery method. Versetta Stone panels interlock tongue into groove and lap in shingle fashion from the bottom of the wall up. Novik panels hook onto a starter strip and lock to each other sideways with tabs. In both cases the crew that puts up the siding puts up the stone, which is the commercial argument for the whole category and the reason the installed cost of a polymer panel is a third of natural stone.

The Nail Is the Difference: Driven Tight or Left Loose

Read the two installation documents side by side and one sentence from each tells you everything.

Versetta Stone: fasteners "should be driven straight and flush into framing." Novik: "never hammer the nails in completely; leave a gap of 1/16 inch." Cement does not move and polypropylene does. A panel that expands has to be fixed at one point and free everywhere else, which is why Novik's guide has the installer nail the centre hole first, so the panel "will ensure even movement of panel in both directions during expansion and contraction," then work outward. Versetta Stone has no centre hole and no movement allowance anywhere in its schedule.

Two lines in that table cost real money and get skipped on quotes.

  • The respirator line is not boilerplate. Versetta Stone contains crystalline silica, and every cut, hole and stagger trim is made with a grinder or a diamond blade. A crew cutting a corner heavy elevation needs dust collection and N95 protection all day. A Novik panel is cut with a finishing blade in a circular saw and makes plastic swarf.

  • The furring line changes the wall build. A Versetta Stone panel goes onto the sheathing. A Novik stone panel, in Canada, goes onto strapping. That is a separate material, a separate labour step, and a different window and door detail, and it is covered in the next section because the requirement comes from the code report rather than the brochure.

How Many Panels and Fasteners Does 100 Square Feet Take?

A Versetta Stone panel covers 2.00 square feet, so 100 square feet of wall is 50 panels and 200 fasteners at the published minimum of four each. A NovikStone Premium Hand Cut panel covers 5.11 square feet, so the same wall is 20 panels and about 98 fasteners. The stone looks similar. The labour does not.

Exposed panel sizes as published by Westlake Royal (ESR-2859) and Novik. Panel counts are area based, so offcuts carried to the next course are assumed reused. Fastener counts use each manufacturer's stated minimum per full panel and exclude starter strip, trim and corner fixings. Artisan Cut shares the Stacked Stone panel size.

The drawing is the argument. Dry Stack and Versetta Stone land in the same place on fastener count, roughly 200 per 100 square feet, for opposite reasons: the cement panel is small, and the polymer panel is nailed more times each. Move up to Stacked Stone or Premium Hand Cut and the count halves, because a panel covering five square feet still only takes five nails.

On a 320 square foot front elevation, a common shape on a Bradford or Barrie new build, that is 640 fasteners in Versetta Stone against roughly 315 in Premium Hand Cut. The large format polymer panels are the fastest stone on the shelf to put up, and they are also the least forgiving of a wall that is out of plane, because a five square foot rigid face cannot be coaxed the way a two square foot one can.

What Has to Sit Behind the Panel in Ontario?

This is the section that separates a supplier answer from a brochure answer, and the two products are not on the same footing.

Novik polymer siding, including every NovikStone profile we stock, is covered by CCMC evaluation report 13420-R from the National Research Council, which reads the product against the National Building Code as an acceptable solution under Subsections 9.27.2 and 9.27.5 and as an alternative solution to the vinyl siding material standard in Article 9.27.12.1. There is also a Ministerial Ruling, No. 14-23-319, authorizing its use in Ontario under section 29 of the Building Code Act. Two things are worth pulling out of that.

The first is the classification. In the eyes of the Canadian code this stone is siding, not masonry, which is exactly how it should be estimated, detailed and flashed. If that sounds like a technicality, note that the same logic governs the layered wall assembly behind vinyl siding: drained cavity, second plane of protection, cladding fixed over it.

The second is the condition attached to the opinion, and it is the single most missed requirement on these walls. The evaluation holds only where the panels are installed on furring over the sheathing membrane, with a continuous, clear, uninterrupted air space between 10 mm and 19 mm, with furring no smaller than 19 by 38 mm and spaced no more than 600 mm on centre, and with flashing that drains water back out. Novik's own installation guides ask for furring at 8 inches on centre with a strip behind every nail, which is tighter again. A Novik stone wall built flat onto the sheathing may go up faster, but it is not the assembly the Canadian evaluation describes, and the rainscreen logic we work through in the house wrap guide is the reason it matters in a climate that drives rain sideways.

Versetta Stone takes the opposite path. ESR-2859 is an ICC report written against the International Building Code and the IRC, and it requires the panel to be installed over solid wood based sheathing: minimum 7/16 inch Structural I OSB or 1/2 inch Structural I plywood over framing at 16 inches on centre, covered with a water resistive barrier, with no cavity called for because the panel carries its own quarter inch rain screen and pre drilled weep holes on the back. The installation instructions add that wall framing should limit out of plane deflection to L/240, that walls must be plumb within 1/4 inch per 10 linear feet, and that anything above 30 feet needs a design professional.

One detail for anyone working to the letter: ESR-2859 states that where it and the printed instructions conflict, the report governs. They do conflict. The report calls for the starter strip to be fastened at 6 inches on centre; the installation guide says every 8 to 10 inches. Use 6.

Weight: 8.5 Pounds a Square Foot Against Three Quarters of One

Versetta Stone weighs 17 pounds a panel over a 2 square foot exposure, which ESR-2859 publishes as an installed weight of 8.5 pounds per square foot. Run the same arithmetic on the Novik stone panels using each one's published panel weight and box coverage and Dry Stack comes out at 0.75, Stacked Stone and Artisan Cut at 0.67, and Premium Hand Cut at 0.84. The method is worth trusting because it reproduces Westlake Royal's own published figure exactly.

The eleven to one spread shows up in four places. A 320 square foot elevation carries 2,720 pounds of Versetta Stone and 270 pounds of Premium Hand Cut. A pallet of cement panels needs equipment on site and a place to put it, where a box of Novik goes up a ladder under one arm, which is what the manufacturer means by single person installation. Cut waste is heavier to move and heavier to dispose of. And the wall itself has to be designed for the load, which is why Versetta Stone publishes a deflection limit and a 30 foot height trigger, and why anyone speccing it over an older wall in midtown Toronto should confirm the sheathing and framing before ordering.

Neither product needs a footing or a ledger, which is the practical difference from the mortar set architectural stone in the same aisle. Kaycan STONEfacade, at about 15 pounds a square foot, is the heavy end of what we stock and the one that behaves most like masonry.

Which Warranty Actually Pays After Fifteen Years?

Both warranties are sold on a headline that the schedule underneath does not support. Novik's lifetime coverage stays at 100 percent with no depreciation only for the original owner, and only if that owner is an individual. Versetta Stone's 50 years prorates from the first month and is transferable only inside the first 15 years.

Years after installation
Read from the published warranty documents: the Novik Siding Products Limited Lifetime Warranty proration table and the Westlake Royal Versetta Stone 50-Year Transferable Limited Warranty. Values are the share of product cost at the start of each year. Neither warranty covers labour to remove or reinstall, and Novik's fade coverage is a separate, shorter and non transferable term.

The Novik warranty document is blunt about who is who. An individual who still owns the building is covered at 100 percent for the life of the building. Everyone else, and the document names companies, cooperatives, trusts, schools, churches and government bodies, is on a 50 year table that pays 100 percent for five years, then steps down through 90, 80, 70, 60, 50, 40, 30 and 20 to a floor of 10 percent from year 15 onward. A builder cladding spec homes in Newmarket is in the second column from the day the panels go up, and so is the family that buys the house from the first owner.

Versetta Stone runs the other way. It has no full coverage window at all: the warranty document works in months out of 600, so a claim in the 240th month pays 360 six hundredths of the product cost. The transfer rule is the sharper edge. The warranty may be transferred to a later owner only during the first 15 years, and that owner's coverage is capped at 15 years from the original purchase date. A 50 year warranty on a resale house is a 15 year warranty.

Neither one pays for labour to strip a wall and put it back. That is normal for cladding and it is the number that actually decides whether a claim is worth making.

How to Order a Mortarless Stone Veneer Wall

Both manufacturers publish a takeoff method, and the two disagree about what a corner is. Work in this order.

  1. Take the net wall area first. Multiply wall width by wall height in feet and subtract every window, door and opening that will not be covered. Both systems are sold against this net figure and neither builds an opening allowance into its coverage numbers.

  2. Measure the corners in linear feet, not square feet. Add up the height of every outside corner, inside corner and end wall termination. Corner pieces are a separate line on both orders and they are the item most often missed on a first takeoff.

  3. Run each system's own corner formula. Versetta Stone takes the corner height in feet multiplied by 0.75 for Universal Corners, and each whole corner panel also covers 2 square feet of field that comes off the flat panel count. A Novik corner assembly is two sections and covers 15.1 inches of corner height.

  4. Convert the field area to panels or boxes. Versetta Stone flat panels are the remaining area divided by 2 square feet. Novik stone panels are the remaining area divided by the box coverage, which is 25.2 square feet on Dry Stack, 49.3 on Stacked Stone and Artisan Cut, and 46 on Premium Hand Cut.

  5. Add the starter, the trim and the waste. Versetta Stone needs starter strip for the base perimeter rounded up to a 10 foot increment and J channel around every opening. Novik needs starter strips and trim at every termination. Add 5 to 10 percent for scrap, and more on a corner heavy elevation.

Two corners of a 9 foot high wall show how far apart the systems are on that one line. Versetta Stone asks for 9 times 0.75 at each corner, so seven Universal Corners apiece and fourteen for the pair, and every one of them is cut in half on site to make a left and a right end. Novik takes the same 18 feet of corner height and divides it by 15.1 inches, so fifteen corner assemblies, which is thirty sections. The unit is different, the price per piece is different, and a takeoff that treats them as interchangeable will be wrong in one direction or the other.

Which One Should You Spec?

The honest answer is that they win different jobs, and the deciding factor is rarely the look.

The jobThe panelWhy
A front elevation that has to read as real masonry up closeVersetta StoneThe face is cast cement with pigment through it rather than a moulded polymer shell, which is the difference people notice at arm's length
A builder cladding spec homesNovikStoneThe warranty table treats a builder as a non individual on both products, but Novik still pays 100 percent for five years and holds a 10 percent floor for 50

A gable or a wall section above 30 feetNeither without design inputVersetta Stone requires a design professional above 30 ft, and STONEfacade states 30 ft as a maximum
A cold weather installEither, and this is the category's real edgeNothing cures on the wall, so a December wainscot in Barrie is a scheduling decision rather than a weather one
Wainscot, porch piers and column wrapsVersetta StoneThe system includes wainscot cap, sill, trim stone, receptacle and light boxes, and a documented 18 in column detail
The fastest square footage per crew dayNovikStone PHC or SKFive square feet and five nails per panel is the lowest labour per wall of anything in the aisle

Two jobs we see regularly in York Region fall outside that table. A homeowner in Richmond Hill matching an existing mortared stone front will not be satisfied by any panel, because the panel look is a running bond of repeated moulds and a mason's wall is not. And an accent wall inside, over a fireplace or in a front hall, is worth reading the fastener tables for. Versetta Stone allows 1/2 inch drywall for interior use only, and then every panel has to be screwed into a stud. A Novik stone or GenStone panel at under a pound a square foot is the easier interior job, and Novik publishes a vertical interior method plus a hard limit of 176 degrees Fahrenheit at any heat source, which rules out the face of a working fireplace.

For the price side of the decision, our stone veneer cost guide for Ontario contractors breaks the installed figure into material, prep and labour, and the short version is that the labour share is what moves, not the stone.

Frequently Asked Questions

Is Versetta Stone real stone?+
No. Versetta Stone is a precast cement panel, made of portland cement, glass fibres and mineral oxide pigments and cast from moulds taken off natural stone. The ICC evaluation report describes it as a glass fibre reinforced cement panel. It is manufactured stone veneer rather than quarried stone, which is why it arrives at a consistent 2 square feet and 17 pounds per panel instead of as loose units a mason sorts on site.
What is the difference between Versetta Stone and NovikStone?+
Versetta Stone is a cement panel with a galvanized steel nail flange that fastens flush to sheathing and does not move. NovikStone is an injection moulded polypropylene panel that expands and contracts with temperature, so its nails are left proud in slotted holes and the Canadian evaluation requires it to sit on furring with an air space behind it. They look similar on a finished wall and ask for different walls underneath.
Does Versetta Stone need mortar or lath?+
No. Full panels fasten mechanically with nails or screws through the steel flange cast into the top edge, with no scratch coat, mortar or metal lath. Cut pieces without a flange are the exception. Those are set in adhesive, and because adhesive will not bond to a water resistive barrier they need clean metal flashing or expanded lath fixed to the framing first.
Can stone veneer panels be installed in winter in Ontario?+
Mortarless panels can, which is their advantage in a York Region build season that loses months to cold. Versetta Stone is marketed as installable in any weather because nothing has to cure on the wall. Novik panels are polymer and stay workable in the cold, though the panel contracts as the temperature drops, so the manufacturer's gaps and slotted nailing matter more on a February install than a July one.
How much does a Novik stone panel weigh?+
A NovikStone Dry Stack panel weighs 1.9 pounds and covers 2.53 square feet of wall, which works out to about 0.75 pounds per square foot installed. Premium Hand Cut is 4.3 pounds over 5.11 square feet, or 0.84. For comparison Versetta Stone is 17 pounds over 2 square feet, which is 8.5 pounds per square foot, and Kaycan STONEfacade is about 15.
Do you need strapping behind NovikStone in Ontario?+
The CCMC evaluation that covers Novik polymer siding in Canada is conditional on the panels being installed on furring, over the sheathing membrane, with a continuous clear air space between 10 and 19 mm. The furring must be at least 19 by 38 mm and spaced no more than 600 mm on centre. Novik's own installation guides go tighter and ask for furring at 8 inches on centre with a strip behind every nail.
Which mortarless stone veneer is best for a builder cladding spec homes?+
Read the warranty schedules before the brochures. Novik's lifetime coverage sits at 100 percent with no depreciation only for an original individual owner, and a builder or a later owner is on a prorated table that reaches 10 percent after 14 years. Versetta Stone prorates from the first month and is transferable only inside the first 15 years, with the later owner capped at 15 years from the original purchase date.
