Specified for lightweight plaster and
screeds, Pratliperl® has been pretreated to enable it to mix with ordinary
cement. The thermal insulation properties of a two-leaf (220 mm) external brick
wall can be doubled simply by adding 16 mm of Pratliperl® plaster on either
side of the wall,
Pratley Marketing Director Eldon Kruger reveals.
“Not
only is Pratliperl® a ‘green’ building material that can assist in meeting
sustainability criteria, the fact that it is ultra-lightweight slashes the cost
of high-rise structures in particular,” Kruger adds. In addition, the product
is highly durable, and features good acoustic properties. It can even be
gunited when applied to large surfaces.
Applications
range from underfloor insulation and insulated roof decks to lightweight
screeds on corrugated iron or concrete roofs, fireproofing structural steel
columns, insulating cryogenic tanks, loose-fill thermal insulation in wall
cavities, and lightweight tile adhesive filler.
Apart
from its excellent thermal insulation properties, Pratliperl® is also resistant
to spalling under fire conditions, which improves the integrity of structures
and enhances health and safety. The product can withstand temperatures of up to
1 250°C without comprising its structural integrity.
Once cured, Pratliperl® has superior strength compared to conventional lightweight concrete. Compatible with cement and other binders, it can be used to produce ultra-lightweight panels, boards, bricks, and blocks that can be cut, nailed, and drilled.
