In Calgary, “smart board” usually means LP SmartSide engineered wood siding: boards made from wood strands treated with resins, waxes and zinc borate, with a paintable, water-resistant surface bonded on top. It is a good choice for Calgary homes when it is installed and finished correctly, because it handles impact and freeze–thaw well and LP’s warranty includes hail up to 1.75 inches. The same name is also used for SmartBoard cement-based boards, a different product used behind finishes rather than as siding.
This guide explains both meanings, how LP SmartSide is made, its strengths and weak points in a Calgary climate, what its warranty really covers, what it costs, and how to keep it looking good.

Key Takeaways
- “Smart board” siding is engineered wood, most often LP SmartSide. It is not the same as Hardie board, which is fibre cement.
- Every board is treated with resins, waxes and zinc borate and has a resin-saturated overlay to resist moisture, fungal decay and freeze–thaw damage.
- LP’s limited warranty includes hail damage from hailstones up to 1.75 inches (45 mm), but the conditions are strict and insurance comes first.
- Installed cost in Calgary is typically about $9–$18 per square foot, more than vinyl and in a similar band to fibre cement.
- Sealed cut edges, proper clearances and a maintained paint finish are what make it last in Calgary.
Smart board in construction: two different products
If you searched for smart board after a contractor or builder mentioned it, you may have found two very different things. Here is how they compare.
| Feature | LP SmartSide (“smart board siding”) | SmartBoard cement board |
|---|---|---|
| What it is | Engineered wood siding, trim and soffit | Rigid cement-based sheets |
| Main use | The finished outside skin of the house | Sheathing, backer board behind finishes, tile underlayment |
| Where you see it | Lap siding, board and batten, panels, trim on Calgary homes | Usually hidden behind other materials |
| Finish | Primed for painting or factory prefinished | Covered by another finish |
Most Calgary homeowners asking about smart board mean the siding, often the board and batten or lap accents on newer homes. The rest of this guide focuses on LP SmartSide. If you are not sure what is on your house, our cladding and Smart Board team can identify it, which matters because the repair method and replacement material are different.
How LP SmartSide is made
LP SmartSide starts with sized and layered wood strands. Using what LP calls its SmartGuard process, every strand is treated to the core with adhesive resins, water-resistant waxes and zinc borate, which helps protect against moisture, fungal decay and termites. A water-resistant, resin-saturated overlay is then bonded to the face, giving the board its wood-grain texture and a surface that takes paint well.
The product comes as lap siding, vertical panels, trim and soffit, either primed for painting on site or prefinished at the factory. According to LP, its lap siding weighs about 45 percent less per square foot than fibre cement and comes in 16-foot lengths, compared with 12 feet for fibre cement, which means fewer joints on a long wall. It cuts with standard woodworking tools rather than the dust-controlled saws fibre cement requires.
Is smart board good for Calgary homes?
For most Calgary homes, yes, provided it is installed to LP’s instructions and the finish is maintained. Here is how the trade-off usually looks.
Where it does well
- Impact and hail. Engineered wood absorbs impact rather than shattering. LP reports that third-party testing it commissioned found its cedar-texture lap siding resisted hail damage better than fibre cement and vinyl, and its warranty covers hail up to 1.75 inches.
- Freeze–thaw. The treated strands and overlay resist water uptake, which is what lets many materials delaminate when water freezes inside them. That matters in a city that cycles through chinooks all winter.
- Wind. LP states its lap siding is designed for wind gusts up to 200 miles per hour when installed to its specifications.
- Look and flexibility. It looks like painted wood, works well for board and batten and accents, and can be repainted a new colour later.
Where to be careful
- It is still wood. Unsealed cut edges, boards sitting too close to the ground, a roof or a deck, and failed caulking let water in, and wet boards can swell and soften.
- Paint is part of the system. Calgary’s strong high-altitude sun wears finishes down, and a neglected finish leaves the board exposed.
- Not non-combustible. Fibre cement does not burn; engineered wood does. That is one reason some owners on tight lots or acreages choose fibre cement.
- Large hail still leaves marks. Hail bigger than 1.75 inches is outside the warranty, and Calgary has seen bigger.
Comparing it with other materials? Our pages on Hardie board siding and vinyl siding cover those options, and our guide on whether vinyl siding is hail-damage proof explains why many Calgary homeowners move away from standard vinyl.

What the LP SmartSide warranty covers
LP SmartSide carries a transferable, prorated 50-year limited warranty in Canada (Quebec has its own version). The key points, based on LP’s warranty for products bought from August 2025 on:
- Years 1 to 5: for covered substrate problems, LP compensates for the cost of labour and materials to repair or replace the affected boards.
- Years 6 to 50: material cost only, no labour, reduced by 2.22 percent for each year after year five.
- Hail: covers cracks, chips or dents larger than 3/8 inch (10 mm) caused by hail up to 1.75 inches (45 mm) in diameter. You must first claim through your home insurance, show evidence of the hail size, and LP then pays only the material shortfall, less insurance proceeds and your deductible, prorated by age.
- Prefinished boards: ExpertFinish products add a 15-year finish warranty.
- Conditions: boards must be installed, finished and maintained to LP’s instructions. Damage from improper cutting, priming or painting, or from conditions that keep the siding wet, is excluded.
In practice, the warranty rewards good installation and upkeep. Keep your invoice and product details, and read the current version on LP’s website before you rely on it.
How much does smart board siding cost in Calgary?
Engineered wood siding typically costs about $9–$18 per square foot installed in Calgary, depending on the profile, whether it is primed or prefinished, and how much trim the house needs. On a home with about 1,800 square feet of wall, that is roughly $16,000–$32,000 for a full re-side, before removal of the old siding and any sheathing repairs. Many homeowners use it only on gables, entries or board and batten accents, which costs far less.
That puts it above vinyl and in a similar band to fibre cement, with quotes that can land a little above or below depending on the product chosen. For a full side-by-side of every material, see our siding cost guide for Calgary.
Installation details that matter here
Most smart board problems we see trace back to installation details, not the product. On a Calgary home, these are the ones to ask about:
- Sealed cut edges. Every field cut should be primed or sealed, especially bottom edges and ends.
- Clearances. Boards need LP’s minimum gaps above the ground, roofs, decks and concrete so they do not sit in snow or splash-back.
- Flashing. Kick-out flashing where a roof meets a wall, and proper flashing over windows and doors, keeps water out from behind the siding.
- Fastening. Nails driven flush, not overdriven, in the right spots.
- Painting on time. Primed boards need a quality exterior topcoat within the window LP specifies.
Maintaining smart board siding
- Walk around the house every spring and after major storms, looking for chipped paint, dents and open caulk joints.
- Touch up paint on scrapes and exposed edges promptly, and repaint when the finish starts to chalk or fade.
- Keep snow piles, sprinklers, soil and mulch away from the bottom boards.
- Clean with a garden hose and soft brush rather than a high-pressure washer.
- Replace damaged boards early. Individual boards can be cut out, replaced and painted to match. Our exterior painting team can refresh the finish.
Hail damage, repairs and insurance
Hail damage on engineered wood usually shows as dents, chipped overlay or small breaks in the paint that leave the board exposed. It is often clustered on the walls that faced the storm. Photograph it as soon as it is safe, because exposed wood needs to be sealed before it takes on water.
Many Alberta home insurance policies cover sudden hail damage to siding, less your deductible, but coverage and matching rules vary, so check with your insurer. Our inspectors document siding damage alongside the roof for your adjuster. Learn more about hail damage repair and our insurance claims process.

Conclusion
Smart board, in Calgary, almost always means LP SmartSide engineered wood siding. It is treated to resist moisture, decay and freeze–thaw, it handles impact well and its warranty includes hail up to 1.75 inches, but it is still wood, so installation details and paint matter. Installed well and maintained, it is a solid, good-looking choice for a Calgary home that sits between vinyl and fibre cement on price.
Frequently Asked Questions
What is smart board in construction?
The term is used for two products. Most often it means LP SmartSide, an engineered wood siding and trim made from treated wood strands with a paintable surface. It is also used for SmartBoard cement-based boards, rigid sheets used as sheathing, as a backer for finishes and as tile underlayment.
Is smart board the same as Hardie board?
No. Smart board siding (LP SmartSide) is engineered wood. Hardie board is fibre cement made from cement, sand and cellulose fibres. Both are painted, both cost more than vinyl, and both are used on Calgary homes, but they are installed, cut and maintained differently.
How long does smart board siding last?
LP backs SmartSide with a 50-year prorated limited warranty on the substrate, with labour and materials covered for the first five years. How long it actually lasts depends on correct installation, sealed cut edges and a maintained paint finish.
Does smart board siding need to be painted?
Yes. Primed boards must be painted after installation, and prefinished boards come with a factory colour. Either way, the finish needs to be maintained and eventually repainted to keep moisture out of the wood.
Can hail damage smart board siding?
Yes. Large hail can dent boards or chip the surface. LP’s limited warranty covers hail damage from hailstones up to 1.75 inches (45 mm), subject to conditions that include filing an insurance claim first.
