Batten / Rafter Planed Fir – Interior Framing, Sections 55x35mm and 55x75mm

This rafter / batten in planed solid fir is a rectangular-section piece intended for interior framing, partition studs, floor supports — interior use only. Available in two sections — 55x35mm for lightweight structures and 55x75mm for more demanding spans — and in two lengths: 200cm and 240cm. The piece is delivered sawn and untreated.

The 4-sided planed fir offers sharp edges and perfectly flat faces — well suited to applications where dimensional precision matters: partition framing, joinery uprights, interior cladding support. The planed dimensions (55mm) are slightly smaller than the sawn size (60mm) due to machining. The term "rafter" refers to use in roofing or inclined structures, "batten" to horizontal use as a support for decking or floor boards — the piece itself is identical, only the use differs. Interior use only.

Uses and applications

As an interior floor batten: primary use. The 55x35mm section is suited to lightweight frames and partition studs. The 55x75mm section is suitable for battened floors with centres ≤ 40cm. Interior use only — untreated fir is not suitable for decking or roof structures.

As a decking batten: horizontal support to which decking boards are fixed. The 55x35mm section is suitable for lightweight frames and partition studs, the 55x75mm section for battened floors with centres ≤ 40cm. Interior use only — not sized for roof structures. Allow a 5 to 8mm gap between battens to allow ventilation beneath the decking.

As interior framing: partition studs, counter-wall battens, interior cladding support or low floor support.

Installation advice

Store pieces flat on a ventilated support, off the ground and sheltered from rain before installation — untreated fir absorbs moisture quickly. For decking, use A4 stainless steel screws or fixing clips. For roofing, prefer bolts or galvanised nails in accordance with best practice. Outdoors, apply a fungicide-insecticide treatment before installation if the species is not naturally resistant.

Maintenance and protection

In dry interior conditions, no treatment required. For visible pieces, oil-wax or varnish recommended. Do not expose to moisture or outdoor conditions — untreated fir deteriorates quickly in damp environments.

WoodUp advice

The planed fir batten 55x35mm is precisely dimensioned — it is suitable for drylining partition frames. These sections are suited to lightweight interior structures, not for roof structures or exterior decking.

Before you buy: The sharp edges of the planed timber may be damaged if pieces are poorly stored or handled roughly. Store flat on a level surface, without excessive overhang.

Frequently asked questions

Which section to choose between 55x35mm and 55x75mm?

The 55x35mm section is suitable for lightweight structures: decking battens with centres ≤ 40cm, light roofing rafters with span ≤ 1.5m, framing battens. The 55x75mm section is suited to longer spans, heavier loads (heavy tiles, snow) or wider centres. If in doubt about sizing, consult a carpenter or timber structural engineer.

What is the difference between a rafter and a batten?

It is the same piece of timber — the difference is purely in the use. As a rafter, the piece is placed at an inclined angle beneath a roof covering. As a batten, it is laid flat, horizontally, as a support for decking boards or flooring. The section and length are identical in both cases.

Does this fir batten need to be treated before use?

Untreated fir is a class 2 species — it is suitable for dry interior use. For any outdoor or damp area use, a fungicide-insecticide treatment is essential before installation. For dry interior use (framing, flooring), no treatment is required.

Can these pieces be cut to the desired length?

Yes. Solid fir cuts cleanly with a circular saw or mitre saw. Order the next length up from your requirement (200 or 240cm) and cut on site. Smooth the cut edges and apply a coat of protection to the cuts if used outdoors.

Which batten section for decking with 21mm boards?

For 21mm thick boards laid on battens, the 55x35mm section with a maximum centre spacing of 40cm is the standard configuration. For 27mm boards or dense timbers (IPE, thick douglas), centres can extend to 50cm. The 55x75mm section is recommended if centres exceed 50cm or if you are laying thick cladding boards.
