Freeze-Thaw Cycles May Damage a Home's Siding

LP Redesigns, Offers Advice and Samples, Compares Sidings

EAST RIVER, Nova Scotia, Aug. 25, 2015 /CNW/ - All types of harsh weather, from freeze-thaw cycles and severe storms to sun, wind and water, can damage home siding. As can termites and wear and tear. Before replacing damaged or out-of-date siding, evaluate all product options, because not all sidings perform the same.  

"LP® CanExel® prefinished engineered wood siding resists damage from freeze thaw, water, impact and termites," said Anne Brannan, LP CanExel associate segment marketing manager.

How do other popular claddings compare to LP CanExel siding? Do your own research to decide, but here is information to consider.

Fibre cement vs. engineered wood – freeze-thaw cycles from Halifax to Vancouver
Fibre cement siding may crack when water penetrates and remains in the cement substrate and freezes and expands as the outside temperature falls. Repeated cycles of freeze and thaw may enlarge the cracks.

From Custom Climate Services Inc. in Regina, Saskatchewan, are these examples of Canadian cities with their average annual freeze-thaw cycles: OntarioToronto, 75, Ottawa, 66, and Thunder Bay, 92; QuebecMontreal, 64, and Quebec City, 65; AlbertaCalgary, 121, and Edmonton, 104; ManitobaWinnipeg, 67; British ColumbiaVancouver, 34; Nova ScotiaHalifax, 85; and SaskatchewanSaskatoon, 79.

Fibre cement is also typically more brittle than engineered wood, making it more susceptible to breaking or cracking such as from a thrown ball or a bicycle pushed against a home.

Vinyl vs. engineered wood
Vinyl siding will fade over time to a different and unpredictable shade. Vinyl becomes more brittle in the winter in colder climates and as such is susceptible to cracking from impact against it. In warmer seasons, pliable vinyl siding is susceptible to damage from impact from stones thrown by a lawn mower, baseballs or hail.

Because vinyl is affixed more loosely on the house to allow for contraction and expansion, a strong wind event may cause the siding to chatter on the underneath structure and adjacent pieces of vinyl. Vinyl siding may also be more challenging to dispose of responsibly.

Traditional wood vs. engineered wood
Unlike some traditional wood siding, LP® CanExel® products resist warping, checking and splitting. Traditional wood typically requires more maintenance, such as paint scraping and more frequent painting.

Relaunched website gives consumers informed choices
LP launched the redesigned English and French CanExel website,, on Aug. 11 to give consumers siding guidance and as a way for them to get free samples of LP CanExel siding.

The site features gorgeous photos of beautiful homes that homeowners can use to create designs and colour schemes for ideas for their own homes. "Homeowners can access 21 classic and trendy prefinished siding colours – including two-tone finishes – to envision their homes in a long parade of dazzling colour combinations," Brannan said.

The site's planning and installation guidance includes building certification codes, an accessories list (e.g., joint flashing, etc.), a support phone number, product locator, tips for easy maintenance and much more.
