Vinyl & Engineered Wood Siding Systems

Vinyl and Engineered Wood Siding for Calgary Homes

Vinyl and engineered wood are the two lighter-weight siding families on Calgary homes, and they behave very differently on the wall. This page compares standard vinyl, insulated vinyl and LP SmartSide engineered wood on looks, upkeep, hail and fire, so you can pick the right one before comparing quotes.

How These Systems Differ

Vinyl siding is the most common cladding in Calgary and the least expensive, a point the City of Calgary’s own climate-ready guide makes. In Alberta, Part 9 of the building code requires vinyl siding to conform to ASTM D3679. Vinyl is sold by nominal thickness in thousandths of an inch, not by gauge: entry lines in Canada run around .040 inch, and premium lines sit in the mid-.040 range, which makes the panel stiffer and less wavy on the wall. Every vinyl system is designed to move. Panels hang loosely on nails centred in their slots so they can expand and contract with temperature, and the industry installation manual notes that a 12-foot-6 panel can move half an inch or more. Nail it tight and the wall has nowhere to go but out of plane.

Insulated vinyl is the same idea with a foam backing bonded to the panel. Its standard is ASTM D7793, and certified insulated siding carries a tested R-value of at least R-2 printed on the packaging; most products add roughly R-2 to R-3.5. The foam stiffens the face, so the wall looks flatter, and the City’s guide says it provides some impact resistance against hail. It is not a substitute for proper exterior insulation, and it remains a niche product in Alberta, so we confirm what is actually stocked before recommending a line.

LP SmartSide is a different material entirely: engineered wood strands bonded with waxes and resins and treated with zinc borate through LP’s SmartGuard process to resist fungal decay. In Canada it is evaluated under CCMC 11826-L against the standard for oriented strand board, so the code’s rules for OSB cladding apply, including sealed edges and a 3 mm gap at door and window frames. It is painted rather than coloured through, needs 200 mm clearance to grade, and is combustible. The City of Calgary rates engineered wood as having good impact resistance compared with vinyl and aluminum.

Choosing Between Them

Vinyl siding for value: Choose standard vinyl siding when budget leads, the house already has vinyl, and hail exposure is moderate. It is light, quick to install and a damaged course can be replaced on its own. It is also the weakest of the three against hail, and it gets stiffer and less forgiving of impact in cold weather.
Insulated vinyl for a flatter, stiffer wall: Choose insulated vinyl siding when you want to stay with vinyl but want panels that sit straighter over uneven walls and resist impact a little better. Treat the added R-value as a modest bonus, not as the energy upgrade itself.
LP SmartSide for a wood look: Choose LP SmartSide siding when you want the deep shadow lines of painted wood and better impact resistance than vinyl, without cedar’s upkeep. Budget for a painted finish, sealed cut edges and careful clearances at grade, roofs and decks.
Step up to fibre cement when needed: If your lot has taken repeated hail, or a wall sits close to the property line, fibre cement instead of either family is often the better answer, and we will say so.

Why It Matters in Calgary

Much of Calgary’s 1990s and 2000s housing was finished in builder-grade vinyl, from Shawnessy and Somerset to Evergreen and Bridlewood in the southwest and Saddle Ridge and Taradale in the northeast. Much of that siding is now showing its age, and in the north of the city the June 2020 and August 2024 hailstorms stripped siding from some homes and left others covered in holes. The Weather Network, reporting on the 2024 survey work, described winds that shred vinyl siding.

Insurance is part of the choice now. Some Alberta home policies carry a roof-and-siding endorsement that settles vinyl or aluminum siding claims on an age-adjusted basis rather than full replacement cost, and insurers in Calgary are increasingly pricing hail risk into policies. It is worth reading your policy before deciding whether to go back to vinyl.

Vinyl & SmartSide: Common Questions

Vinyl or LP SmartSide for a Calgary home?

Vinyl is lighter, costs less, needs no paint and is easy to patch one course at a time, but it is the most hail-vulnerable siding we install. LP SmartSide looks like painted wood, resists impact better, and LP backs it with a 50-year prorated limited warranty that includes limited hail-damage coverage; the full terms, including hail-size limits, are in LP’s current warranty. In exchange it needs a paint finish, sealed cuts and stricter clearances. If you plan to stay a long time in a hail-prone part of the city, engineered wood is usually the stronger long-term choice.

After hail, should I re-side in vinyl again or change materials?

Start by looking at how often your walls have been damaged and what your policy now says about siding. If the vinyl lasted many years and the damage was a single event, a quality vinyl or insulated vinyl may be the sensible replacement. If your community has been hit more than once, moving to engineered wood or fibre cement reduces the chance of doing this again. We give you the scope for each option so you can compare them on the same wall area.

Can vinyl or LP SmartSide go on a wall close to the property line?

Sometimes, but with limits. Where a wall is less than 1.2 m from the property line, the building code calls for a fire-resistance rating and allows vinyl only in specific assemblies, such as over gypsum sheathing. LP SmartSide is combustible and needs an assembly check before it goes near a property line. Non-combustible claddings such as fibre cement or metal are the straightforward choice on tight side yards, and we confirm the limiting distance before specifying any wall.
