Description

Premium Redwood door lining is a softwood joinery timber supplied planed all round (PAR) to a smooth, consistent finish. The 27 x 132mm cross-section is a traditional UK trade size widely used for internal door frames, linings, and architrave applications. At 4.2 metres in length, a single length covers most standard domestic door openings with minimal cutting waste. The timber arrives ready to fit, eliminating the need for on-site planing and reducing labour time on installation.

Redwood is chosen for door lining work because it machines cleanly, holds fixings well, and accepts paint and stain finishes reliably. Premium grade timber has fewer knots and defects than standard grades, making it suitable for visible joinery where appearance is important. The PAR finish ensures uniform dimensions, which is essential when fitting multiple pieces around a door opening or when matching existing joinery. This product is suitable for both new build and renovation work in domestic and light commercial settings.
