- Sound
Absorption: - NRC 0.66. Full sound
absorption, attenuation and sound transmission
test reports are available.
-
- Thermal
Resistance: - R 1.24. Approximately equivalent to
35mm fibreglass insulation. Thermal resistance can be further enhanced if
Solomit is used in conjunction with a double
sided roofing foil. Where temperature range is
extreme (e.g. Alpine regions), seek expert
advice.
-
- Fire
Resistance: - Department of Health "B"
Grade Fire Rating. Solomit complies with current building regulations for public
buildings. AS 1530 - Part 3, 1982. Fire test reports are available.
-
- Note: - Solomit is not suited for
exterior use, but where exposed to moisture must
be sealed with a coat of clear lacquer.

For nailing up
butt joint sheets: -
- Where a different
module size is required, the restriction, is that
the standard wire spacing of 127mm cannot be
changed, and a minimum of 25mm beyond the last
wire is necessary. The overall sheet width will
be determined by these parameters. (Note: Any
width over 1200mm should have centre fixing.)
INSTALLATION
AND PREPARATION:
The
installation of Solomit is simple provided the following
important points are followed:
*
.with a flat roof or
steel deck, a sarking of aluminium foil is necessary.
*
tto avoid moisture
condensation, allow adequate ventilation between roof and
...Solomit.
* .all ventilators and
other openings should be screened to prevent infiltration
of rodents as the anti-mould anti-rodent
treatment which is applied to the back of the sheet is a
repellent only.
* aSolomit must be
kept completely dry.
*n.Solomit must always
be carried on edge.
* .do not walk on
Solomit before or during installation.
* .if through
handling, sheets become out of square, this can simply be
corrected before installation by racking until square.
* .during manufacture,
sheets are given a "right" and
"wrong" side. Before installation,
sheets can be brushed clean of flake and loose ends using a stiff bristled broom. The
sheets are then stood on edge and the back hit with a piece of timber to remove
any residual dust.
* .staining and
painting of timber (beams, cornices, cover straps, etc.)
should be completed before Solomit is installed.
Fire
Resistance:
- Solomit
has a Department of Health "B" Grade
Fire Rating and is accepted as a fire resistant
lining material for all public buildings. In the
test illustrated, it took 20 minutes to burn a
hole with a blow lamp. The Solomit material did
not catch alight but simply carbonised. When the
flame was removed, carbonisation ceased.
Physical
Properties:
- Solomit
building sheets are manufactured in Australia and
are compressed strawboard made from selected
clean straw. The compressed straw is reinforced
with galvanised wire running along the full
length of the sheets and held in compression with
wire stiches. The sheets therefore are rigid and
support their own length when installed
correctly.
How
to cut Solomit sheets:
- Solomit
sheets can be cut longitudinally by using a fine
tooth power saw, cutting between the wires. To
cut across the sheet, snip the wires between the
staples, turn the ends of the severed wire back
over the nearest staple, and repeat the procedure
with the wires on the under surface. The sheet
will then break off leaving a clean edge.
