PERLIV 

Perlite also offers a wide spectrum of simple and economical solutions in the construction field.

Its use as aggregate to, or substitute for, traditional materials allows a remarkable reduction in structures' calculation due to its low specific weight, which many times is lower than weight of traditional materials.
Small glass spheroids generated in its formation process at high temperatures turns combinations containing perlite into excellent thermal and sound insulators.
Its use is very simple. It is combined with cement and lime and/or gypsum, being its application the same of traditional plaster, and achieving a fine termination and an excellent thermal and sound insulation.

Thermal insulation

It offers thermal insulation superior to all known products and it is similar to cork, but has significant advantages with respect thereto. Perlite combinations do not retain water, are non-combustible, and, due to its organic origin, it does not decompose, and is unchangeable for the presence of chemical and physical agents. When used in constructions, it highly protects rooms from climate and walls and ceilings from condensation.
A 10-cm wall of pure perlite thermal insulation is equivalent to 50 cm of expanded clay, 80 cm of volcanic granule or 1.20 mts of concrete wall.

Since it is very low in density (approximately 100 Kg. per m3), it is 15 times lighter than sand, 8 times lighter than expanded clay and 8 times lighter than volcanic granule.

Either loose or combined with gypsum or cement, expanded perlite highlights its isonorizing properties, reduces sound transmission from 60 to 80% from one room to another, also diminishing sounds from the exterior.

Combinations obtained from perlite constitute a material which handling, mixing and application on the job site is very easy. Its uses and application chances are as wide as versatile. This allows premolded pieces being fabricated in any size, light concrete, etc. It does not require special equipment, or techniques, and there is no need of cuttings or adjustments.
