Compressibility reduces the number of truckloads
required
to transport insulation to the building site. Fewer truckloads
mean fewer trucks which, in turn, means
less fuel and exhaust
emissions
.
Good product design reduces waste during installation
. Mineral
wool can be purchased in different sizes and thicknesses.
Installation waste is therefore minimised and can be returned to
the manufacturer for recycling.
Mineral wool products are developed to live up to
the highest
health and safety standards
for both installers and users.
As regards handling practices, producers have committed
themselves to developing
pictorial packaging communication
standards
to ensure that the installers are free from any
discomfort.
Safe Use Instruction Sheets
similar to safety data sheet are
also available from each producer.
Step 3: Curing: cooling, and product finishing
The resin-coated fibre is drawn under suction onto a moving
conveyor to form a mattress of fibres. This mattress passes
through a gas-fired oven, which dries the product and cures
the binder. The product is then air-cooled and cut to size before
packaging.
Edge trims can be granulated and blown back into the fibre veil,
or they can be combined with the surplus product to form a
loose wool product.
In the mineral wool sector, the emissions to air can be divided
into emissions frommelting activities, and emissions from
downstream processes.
Curing oven emissions contain volatile binder components,
binder breakdown products, and combustion products from the
oven burners. These emissions are minimised by appropriate
techniques for handling and spillage containment, and residual
levels of pollution can be treated with standard techniques.
Typical techniques for reducing the emissions are impact jets
and cyclones, wet scrubbers, wet electrostatic precipitators,
stone wool filters and waste gas combustion.
For new plants, the best available technology, as described in
the “Best Available Techniques (BAT) Reference Document for
the manufacture of Glass” must be used. The application of the
BAT has resulted in a considerable reduction in emissions over
the last decade.
Emission

To have a net positive impact on sustainability, a material must be easy to
transport. Mineral wool insulation fts the bill nicely, because its fbre mats
are compressible…
by a factor up to 10!
