Pratliperl is a unique ultra lightweight and insulating material of volcanic origin, a deposit of which is found at only one location in South Africa and nowhere else. Unlike ordinary Perlite, Pratliperl is unique in that it is well suited for use with Cement. The reasons for this are twofold. Firstly: Unlike ordinary Perlites which are brittle and friable, Pratliperl has a tough surface structure. Secondly: Pratliperl is pre-treated with a special chemical, thereby rendering it compatible with ordinary Cements and additives.
Pratliperl has a conductivity (k) value in the loose state of 0.05 W/m.K. This is 20 times more insulating than sand! This property derives from the low density and the “vacuum flask” like structure of Pratliperl beads.
Loose density is approximately 100 kg/m* and, when mixed with cement, practical concrete densities range from 300 kg/m* to 1100 kg/m3 depending upon mix. Concrete that floats on water!
Ordinary lightweight concretes are typically weak. Aerated concrete is also susceptible to total slump shortly after casting, especially if any vibration or disturbance like passing traffic is present.
Zero Smoke & Fumes
Pratliperl releases no smoke or fumes during a fire. This property gives Pratliperl an advantage over expanded Polystyrene based insulation products which may give off harmful fumes.
Compatible with Cement/Binders
Each Pratliperl particle has a well-sealed and tough bead structure. This ameliorates bead damage during mixing and facilitates low water adsorption and proper curing of the cement.
In addition to the almost refractory melting temprature of 1250 degree celcius, pratliperl concrete also maintains its high temperature structural integrity via its incredible thermal solutions.
Pratliperl the Ideal Insulator
• You Can Save More Than 60 % Of Your Home Electricity Bill With Pratliperl.
