Pratley is introducing an ultra-lightweight, thermally-insulating and fireproof aggregate for plaster screed and concrete called Pratliperl®.
Pratliperl® from Pratley assists the construction industry in meeting quality standards such as SANS 204, which is particularly important due to an increased focus on energy efficiency in building.
Useful for 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, Pratliperl® is also resistant to spalling under fire conditions and withstands 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.
