How do I cut and work Woodtex panels?

In exactly the same way as you would a similar sized timber panel. You can use panel saws, routers, hole saws, planers, circular saws or handsaws. Please note that the cement content in Woodtex will dull the cutting edges faster than normal wood cutting does. We therefore recommend the use of Tungston tip blades.

Can I paint Woodtex?

Yes, you can paint Woodtex, using the same system as you would for exterior timber fencing. However, the recommended painting procedure is that the panels are spray painted, using two coats of an acrylic paint, prior to leaving the factory, as our staff have mastered the correct coverage required, without decreasing the sound absorbing properties of the panel.

An approximate coverage is 5 square metres per litre of paint (two coats).

Is Woodtex environmentally safe?

Yes, Woodtex is manufactured from only two ingredients, untreated timber fibre (Pinus Radiata) and Portland cement, and no other additives are required. The timber is sourced from a sustainable forest, only from within New Zealand.

How do I join Woodtex panels?

Woodtex panels are dimensionally accurate, and thus may be butt jointed, over the long (2400mm) side. The short (600mm) side may be butt jointed too, but will require mechanical fixing restraints within 150mm of the edge, to prevent any visual misalignment due to long term bowing of the panel. In an exterior installation, where a visually sound architectural joint is required, it is recommended that a bevel edge be cut over the short (and long, if required) sides to create a shadowline effect, that will tolerate and conceal minor movement.

What is the recommended method of fixing Woodtex panels?

Woodtex is generally fixed to timber battens using coarse thread chipboard screws, to concrete using Hilti or Ramset fixings, or to metal purlins / girths using roofing or Tek screws. Woodtex may be used as a fixing substrate for light loads only, as the screws may tear themselves out under severe shear stress.

Is Woodtex affected by water?

Like all timber products, Woodtex has an ability to absorb and dissipate water. When used in an exterior application, a small amount of bowing may occur, predominantly at the short (600mm) end, this is best minimised by restraining movement capability via screw fixings within 150mm of the edge.
Such movement is generally not noticeable in the thicker Woodtex sizes of 38mm and 50mm thickness. The design of the application should be such that the Woodtex panel can "free drain", and have a capping over the top edge.

What is the correct method to store Woodtex panels?

Woodtex is best stored stacked in a cool and dry location. If intended usage is within an indoor situation, when stored outdoors it is recommended that the stack be covered with plastic or tarps, to prevent the ingress of water. If Woodtex has been stored in rain or humid conditions, and the intended usage is an internal one, then the Woodtex panels must be air dried prior to fixing.

Is there a "correct" side to Woodtex panels?

One surface of the Woodtex panel has a planed finish, this is the mould side, while the other side has a manufactured finish. Both sides are visually acceptable and similar, and have identical acoustic properties. However, when Woodtex is used for an architectural finish, it is recommended that the planed side is the side to be fixed to the wall or ceiling battens.
