Species Description

Western Red Cedar (Thuja plicata) when installed has a variety of reds, pinks & brown colours making it one of the elites when it comes to attractiveness. The timber can also be left untreated several years to achieve a classic silver colour. Western Red Cedar’s durability is second to none in terms of timber cladding, it is extremely resistant to decay splitting & movement once installed. All of Duffield’s Western Red Cedar is sticked & dried on site to less than 20% moisture content. This, along with the timbers colour & physical properties, makes Western Red Cedar a go-to choice for external timber cladding.

Profile Description

Shiplap Half Lap Cladding is a traditional choice of profile usually associated with more of a rural setting. A variation of the standard profile without the tongue and groove. Instead the timber is rebated at the rear for each piece to slide into one another. It creates a soft curve shape that when installed also aids with water runoff. A soft and traditional profile.
