The Story
Redwood tongue and groove flooring boards in 25mm x 150mm offer a solid, traditional timber floor suited to domestic and light commercial use. Machined from kiln-dried Scandinavian redwood, the interlocking profile creates a tight, stable surface with a finished size of approximately 20.5mm x 144mm.
Specifications
| Property | Detail |
|---|---|
| Material | Scandinavian redwood (Pinus sylvestris) |
| Treatment | Kiln dried |
| Nominal Size | 25mm x 150mm (6 x 1 inch) |
| Finished Size | Approximately 20.5mm x 144mm |

What it's used for
- Suspended timber ground floors and first-floor decking in residential properties
- Loft boarding and subfloor installations where a solid, load-bearing surface is needed
- Home offices, studios, and workshop floors requiring a clean, durable finish
- Renovation and replacement work where existing T&G boards need like-for-like matching
Fitting and handling
Allow the boards to acclimatise in the room for at least 48 hours before laying, keeping them flat and away from direct heat sources or damp. Secret nail or screw through the tongue at each joist crossing, using a minimum of two fixings per board per joist. Once laid, the surface can be sanded and finished with a hardwax oil, floor varnish, or wood stain to suit the space.
FAQ
What is the difference between nominal and finished size on these boards?
The nominal size of 25mm x 150mm refers to the sawn dimension before machining. After planing and profiling, the finished size is approximately 20.5mm x 144mm. Always use the finished size when calculating coverage and specifying joists or noggins.
Can these redwood T&G boards be used as loft boards?
Yes. At 25mm thick, these boards are a common choice for loft boarding over joists as well as subfloor use. Check your joist centres first and ensure the boards span at least two joists without unsupported edges. They are sold in the Subfloor and Loft Boards category at Nottage Timber Merchants for exactly this reason.
How much should I order to allow for waste?
A general allowance of 10 to 15 per cent for cutting waste and board selection is standard for T&G flooring. In rooms with alcoves, chimney breasts, or angled walls, allow towards the higher end. Order by linear metre based on your floor area divided by the finished board width of 144mm.
