Cladding Options Compared: Cedar, Larch or Composite?

What is Cladding?

Cladding refers to overlapping layers covering exterior walls, providing weather resistance, thermal insulation, and aesthetic appeal. These panels or boards shield buildings from the elements while enhancing visual style. Common options include cedar cladding, larch cladding, and composite cladding.

Cladding serves four core functions. It acts as a weather barrier against wind-driven rain, with materials like cedar and larch offering natural breathability while composites provide non-porous protection. Proper installation ensures water sheds effectively away from walls.

The second function is a thermal break, where wood options like western red cedar provide moderate R-value through their density, and composites often match or exceed this with engineered insulation properties. This helps reduce heat loss in cooler climates. Experts recommend pairing cladding with cavity insulation for best results.

Additional roles include aesthetic finish with natural wood grain or textured composites, and fire resistance, such as Class B for cedar versus Class A for many composites. A typical cross-section shows cladding boards over a 15-25mm air gap on battens, forming a rain screen system for ventilation and drainage. Installation standards require this gap to prevent moisture buildup, using subframe systems with hidden fasteners or face nailing on treated lumber.

Cedar Cladding

Western Red Cedar offers premium natural beauty with a 25-40 year lifespan but requires diligent maintenance in harsh climates. Sourced from the Pacific Northwest, this Western Red Cedar (Thu-ja plicata) has a density of 380kg/m³ and natural oils that resist rot. Experts recommend it for exterior cladding where aesthetic appeal matters most.

Available in grades like Clear (no knots) and Knotty, it suits various budgets in cladding options. Clear grade provides flawless surfaces for high-end homes, while knotty offers rustic charm at lower cost. Research suggests proper grading ensures better rot resistance.
