Kiln Dried vs. Air Dried: What Actually Changes
If you've ever stood in our yard comparing two stacks of pine wondering why one costs more, it usually comes down to one thing: moisture.
Kiln dried timber is dried in a controlled chamber down to around 8–12% moisture content. It's more stable, straighter, and far less likely to twist, cup or shrink once it's fixed in place — which is why we recommend it for flooring, skirting, internal cladding and anything that needs to stay put.
Air dried timber is dried naturally over weeks or months and typically sits higher, around 15–20% moisture. It's more affordable and perfectly good for structural framing, fencing, pallets and outdoor work where a little movement isn't going to show. Neither is "better" — it's about matching the drying method to the job. Get it wrong and you'll be back sanding a cupped floorboard six months later.
