The structure and chemical composition. Foamglass "Penosital" is foamed at a temperature of 750 - 850 ° C glass. It consists of gas-filled cells separated by finest walls. These partitions, in contrast to the foam concretes and not friable and porous and continuous, smooth and melted. The chemical composition of the foam glass corresponds to the usual glass.
Environmental security. The chemical composition corresponds to the usual Molten glass is 100% inorganic material does not contain or release any hazardous substances. Bottle made of glass cullet at a temperature exceeding 800 ° C and not subjected to any further chemical processing. Unlike the mineral wool products it is not a source of any fibers or carcinogenic toxic vapors of organic binder materials.
High thermal insulation properties. For the most common types of foam glass "Penosital" with a density of 120-200 kg / m3, the rate of thermal conductivity varies between 0.05 – 0.07 W/(m °C ).
High strength. Foamglass "Penosital" have unique mineral porous materials ratio of strength - density. Neither mineral porous material does not have such a high compressive strength (0.5 - 1.5 MPa without any deformation!) With such low density (120 – 200 kg/m3.
Fire safety and resistance to high temperatures. Foamglass "Penosital" as a purely mineral inorganic material is absolutely not combustible. Guaranteed operating temperature range of foam glass from -200 до +500 °C. -200 to +500 ° C. Foam glass begins to break down at the softening point 600-800 °C.
High sound insulation properties. The porous structure of the foam glass "Penosital" provides excellent sound insulation properties.
Water resistance. Foam glass "Penosital" made of glass hydrolytic class, so even though such a highly developed surface ratio of softening foam glass is at a level not lower than 0.95 (practically granite).
Chemical resistance. Foam glass "Penosital" resistant to aggressive environments. Foam glass dissolves only hydrofluoric acid and concentrated alkaline solutions. In other cases, an inert!
Biological and bacteriological resistance. Foam glass "Penosital" being obtained at temperatures of about 750 - 850 ° C, is sterile. Due to the complete absence of organic matter, it does not contain the nutrient medium for the flora and fauna, including micro-organisms. Impermeability or very low permeability to liquids and foam glass, especially, aqueous solutions of foam glass prevents contamination by microorganisms, spores and bacteria.
The stability of the physical properties. Foamglass "Penosital" remains stable physical parameters in the whole temperature range of application, as well as in a variety of harsh environments (eg, high humidity, water content, temperature variations, etc.)
Low linear expansion. The coefficient of thermal expansion of glass foam 7-8 times lower as compared to commonly used polymeric insulators. This is especially important for the Russian climatic conditions under which the temperature difference summer-winter exceed 60-70 degrees, resulting in large deformation changes gap between the plates in the polymeric insulation of walls and roofs. Similarly, polymer fillers behave in light of building blocks.
Durability. Typically, foam glass claimed the life of 50 - 100 years or "lifetime of the structure." Houses built of blocks of pumice, the nearest analogue of natural foam glass cost hundreds and even thousands of years. The first building, which used artificial foam glass (pumice), was built in 1942. It has passed since '72! Screening autopsy show how the immutability of the material and the constancy of the coefficient of thermal conductivity.
Easy to install. Foamglass "Penosital" can be mounted using virtually any solution, binders and adhesives. Due to the extremely advanced cellular surface, foam glass can be glued even astringent, has low adhesion to glass.
The possibility of multiple reuse.
Modification. Directed synthesis allows to produce foam glass of various kinds and types of both structure and composition: Granular, slab, block, a vapor, vapor permeable and noise, special (eg protection against radiation) and so on.

Foam glass "Penosital" is a unique insulating material on a range of properties. With high thermal insulation properties, foam glass does not burn, it is resistant to heat and aggressive chemicals, durability, frost resistance, is ecologically safe. So the foam glass can be used in many sectors of the economy to address the problems of energy saving and reliability: in the residential and industrial construction for thermal insulation of pipelines and equipment for road construction.
