Softwood wood or sawn timber (usually redwood wood) that has been pressure-impregnated with a preservative to protect it from insects and fungi. Dunelm sawn timber is treated under pressure with Secure, which is a mix of copper and organic co-biocides that protects best against insect and fungus attacks that cause decay.
How is Treated Wood different from Untreated Wood?
Wood that has not been treated or “sawn” is in its natural state. and, because of that, doesn’t protect the environment. Pressure is used to put chemicals into treated wood to protect it from the weather.

Tips to Take Care of Sawn Timbers
Fresh-sawn timber products should be installed immediately where possible. If you need to store them, keep them outside, covered, and out of direct sunlight so they don’t dry out or fade. If the products are individually wrapped, you might want to take them out of the packaging so that condensation doesn’t build up and cause stains. If stains do happen, they can usually be removed by lightly sanding the wood surface after it has dried. When things are stacked, there should be space between them so air can flow.
Advice for Installation
We recommend that products be concreted in. The amount of concrete needed will depend on the size of the product, the ground conditions, wind loads, etc. Don’t get concrete on the wood, because it will stain it. Concrete can be backfilled until it is 50 mm below ground level, and then it can be troweled away to let water drain away.
Advice for Maintenance
A light sanding once a year, when the wood is dry, will help keep things clean and stop dirt and moss from building up. The wood naturally has an attractive silver-gray color, which is something that many customers want. If you want to keep them from fading, you can treat them with Osmo UV-Protection Oil. If they are very faded, you can use Osmo Wood Reviver Power-Gel to bring back the color.
What are “off-sawn” and “rough-sawn” pieces of wood?
“Off Sawn Timber” is a trade term for cut wood. This just means that a large band saw is used to cut the tree trunk into pieces. The cut pieces are obviously rough on the outside… Off Sawn Timber is the name for these pieces.
Rough-sawn timber is another trade term that means the same thing as above. This is when a band saw is used to cut the tree trunk, giving it a rough, “unfinished” surface.
The surface is then smoothed with sandpaper.
Rough Sawn Wood shouldn’t be used for building structures because it hasn’t been tested or graded for its strength.
As mentioned above, there are a few important things to keep in mind when choosing structural-sawn timber for your building project. Savewithnerds.com is the official website where you can find out more.
