Builder Illustration

Are you a builder and looking for timber?

Why Radial Timber should be specified and used on your next project?

1. Environment – Sustainable

The radial process produces more wood from fewer trees. It is an ideal process for processing small diameter plantation sawlog

2. Quality – Consistent

Every piece of radially sawn timber is cut in exactly the same way so our products perform predictably.

3. Point of Difference – Unique

Many of the Radial Timber profiles are unique and interesting designs which is why project featuring our products win so many awards

4. Chain of Custody – Traceable

Radial Timber is growing, drying, milling and selling all it is own product. We are in controlled of where the timber comes from and how it is processed

5. Design for Durability – Knowledge

We are very experience in every technical aspect of timber and how to maximise its performance on your next project. Our architect rep is available to discuss special requirements for any project you may have

Board and Batten

Setting up: Board & Batten cladding is typically installed in a regular pattern with base boards spaced and fixed to the frame first (wide face out). Batten or cap boards are then fixed over the gap with the narrow face out (see Figure 1). Fixing battens or noggings should be spaced at maximum of 600mm centres. While fixing battens may increase the overall wall thickness, they can be quicker to install and easier to level than noggings. Typically we recommend 75×35 r-7 treated pine for Battens. Each sq. metre of Board & Batten cladding is supplied with an allowance for this cover included. Sisalation should be fixed to the stud wall with the fixing batten installed over the sisalation. Mitred joins on loose boards should be used on external corners and glued with flexible polyethylene glue.

Installation: When fixing base boards, ensure gaps are set so that the cap board will cover the edge of each base board by a minimum of 25 to 30mm to allow for natural shrinkage. For the standard 100mm combination of boards, a gap of 50mm should be allowed between base boards. Cap boards should be fixed promptly to base boards, to facilitate the boards seasoning and ‘locking’ together, and avoiding uneven movement. Boards should not be installed on hot windy days in full direct sun, as these conditions increase the risk of boards cupping or distorting.A

Radial Timbers can supply suitable hot dipped gal batten screws.

Fixings: Base boards can be gun nailed or hand nailed but care should be taken close to the ends to avoid splitting (65mm galvanised or stainless steel twisted shank nails preferred). It is recommended that cap boards be fixed with 100mm stainless steel or hot dipped galvanised batten screws (NOTE: if nailing cap boards, hardwood framing and 2 x 100mm long nails are preferred). The recommended fixing rate is two nails per base board and one Bugle Batten Screw for cap boards.

Board and batten is supplied in freshly cut grain boards which should be installed within 4 weeks of being milled to ensure the best round quality. It is important that orders are placed so that boards are not stored on site for more than 2-4 weeks. They should be kept wrapped in plastic with a tarp over the pack to avoid the boards drying out before fixing.

Seasoning & Storage: Some surface checking may occur during seasoning but these non structural cracks will close again as moisture content in the boards equalise (NOTE: unprotected west facing walls may be subject to extreme temperature changes and therefore, timber is more likely to check or move). It is normal for all hardwoods to leach red/brown extractives during heavy rain periods. Extractives tend to be less prominent in lighter species but it is advisable to protect walls/paving until the extractives have finished leaching (can vary but leaching will generally continue for up to 6 months). Packs should be kept fully wrapped, weighted and off the ground in a level position before fixing to prevent uneven drying or distortion.
