Ironwood shingles have been used in our region for over 100
years.
Ironwood unlike cedar is exceptionally hard and resistant to
rot & decay. After prolonged exposure shingles will take on a distinctive
grey black patina. Until now these shingles were only available in flat 6mm
thick pieces around 70mm wide.
Venturer together with our
manufacturing partners has taken this tried and tested product one step
further. We have developed a special taper sawn process, which allows shingles
to have a chunky 11mm butt which tapers to a 3mm at the concealed end.
Shingles can now be produced nearly twice the width and installed as a system
roof, similar to its cedar counter part.
For a prestigious reference for
this please refer to the Datai hotel in Langkawi which uses the traditional
ironwood shingle.

The
acceptable method for application of spaced batten is to space 1 x 2 / 1 x 4
boards to coincide with the weather exposure (refer attached chart) of the
shingles (Figure 1).
Thus, if the shingles are to be laid at 250 mm to
the weather, the sheathing boards would also be spaced at 250 mm on center.
In this method of application each shingle is nailed to the center of the
batten, and shingles must be pre drilled prior to fixing.
Application
Regardless of style,
the following basic application details (Figure 1) must be observed.
1. Shingles must be
doubled or tripled at all eaves.
2. Butts of first
course shingles should project 38mm beyond the fascia and approximately 25mm
over the gable or rake end.
3. Spacing between
adjacent shingles (joints) should be a minimum of 6 mm and a maximum of
12mm.
4. Shingles shall be
laid with a side lap not less than 25 mm between joints in adjacent courses,
and not more than 10% shall be in direct alignment in alternate
courses.
