LP Siding vs Wood: Why Engineered Wood Wins in Calgary

What is LP Siding?

LP (made by Huber) is engineered wood siding composed of wood strands bonded with resin. Unlike solid wood, LP's composition makes it more stable across humidity and temperature changes—a critical advantage in Calgary's variable climate.

LP offers the aesthetic warmth of wood while addressing solid wood's moisture susceptibility.

LP vs Solid Wood: Key Differences

Moisture Management:

LP: Engineered composition resists cupping, warping, and moisture swelling. Performs significantly better in Alberta's variable humidity.

Solid Wood: Absorbs moisture readily. Cupping (edges curl up) and warping are common in humid climates.

Paint Retention:

LP: Superior paint adhesion. Paint retention is excellent if properly sealed. 7-10 year paint cycles typical.

Solid Wood: Paint often peels after 3-5 years due to moisture penetration and thermal movement.

Durability:

LP: 15-25 years with regular maintenance. Resists rot and insect damage better than wood.

Solid Wood: 10-20 years. More vulnerable to decay, termites, and moisture damage.

Cost:

LP: $8-15/sq ft installed

Solid Wood: $8-12/sq ft installed (often higher due to hand-select requirements)

Calgary's Climate Impact

Calgary's seasonal humidity swings (40-80% relative humidity) stress solid wood siding. Expansion/contraction causes paint to crack and peel. Moisture infiltration leads to rot at sheathing and framing.

LP's engineered composition handles these swings more gracefully, reducing moisture-related damage.

Maintenance Requirements

LP Siding:

• Paint every 7-10 years (vs. 3-5 for solid wood)
• Inspect annually for moisture issues
• Caulk joints and penetrations
• Seal cut edges after installation

Solid Wood:

• Paint every 3-5 years (labor-intensive)
• Stain/seal annually in some cases
• Monitor for wood rot and insect damage
• Replace damaged boards more frequently

Our Recommendation

Choose LP for Calgary homes: Better performance in humidity swings, superior paint retention, longer intervals between maintenance. Cost-effective for long-term value.

Solid wood has charm and character but requires more intensive maintenance in Alberta climates. If you prioritize the aesthetic of solid wood, commit to regular staining/sealing schedules.
