What are foam glass blocks? Foam glass
Lightweight, rigid insulating material composed of millions of completely sealed glass cells, each an insulating space.
Often referred to also as “cellular glass”
Blocks
The superior properties of blocks made of foam glass have made them ideal insulation material for construction industry.
Main properties include:
Completely noncombustible •Has zero smoke development and flame spread classification
Ecology-friendly •Production process utilizes waste recycled glass as a raw material.
Low thermal conductivity •Can be used as insulation material in the range of -260°C to +485°С
Low noise conductivity •Sound absorption figure reaches 56dB
Dimensionally stable •Has coefficient of thermal expansion similar to concrete and steel
Waterproof •Since it is made of pure glass
Acid resistant •Since made of glass
Pest-resistant •Due to its inorganic nature
More than 100 years life-time

Our uniquely designed fully automated production line is able to manufacture foam glass blocks priced at 40-45% lower
R&D related to chemical features of the glass necessary to batch preparation
Missing part
R&D to be performed Development of “European” technology to batch preparation necessary for manufacturing of foam glass blocks (based on existing research):
Manufacturing of foam glass from regular waste glass avoiding melting proprietary glass
Foaming under normal atmospheric conditions
Reducing energy needed to foam glass manufacturing (foaming temperature reducing, optimization of temperature curve, etc. )
Lowering batch preparation costs by optimization of chemical ingredients
Creation of homogenous closed pore structure
Development of type of batch for manufacturing foam glass blocks with high absorption of electro-magnetic radiation
Development of type of batch for manufacturing foam glass blocks with high noise absorption (open pore structure)
Compliance with EU and International standards (ASTM C552, DIN EN13167 + A1)
Action items Pilot production facility for foam glass blocks in molds / batch lab
Development of proprietary equipment for thermochemical processing and refinement of glass powder
Development of technology of foaming agent nano-coating application to glass powder
LfG production line customization for different type of batch

Technological expertise reference – fully commercial manufacturing facility
LfG team has designed, constructed and assembled two full-scale commercial foam glass production lines in the Russian city of Vladimir.
The lines were deployed during the period of 2014 and 2015 and are currently fully operational with overall annual manufacturing capacity of up to 110,000 cubic meters
