How does Scots Pine compare to Spruce for structural framing?

Both species achieve C24 grade and perform identically in structural calculations once graded. The key differences are practical: pine is heavier (420 vs 400 kg/m³ mean density), accepts preservative treatment more readily due to its permeable sapwood, and has higher natural durability.

The key differences are practical: pine is heavier (420 vs 400 kg/m³ mean density), accepts preservative treatment more readily due to its permeable sapwood, and has higher natural durability. Spruce is lighter, more dimensionally stable, and dominates the glulam and CLT market due to its consistent properties and lower resin content.
