Foam glass
(cellular glass) is a new kind of inorganic heat insulating
material with a structure of equallyclosed cells. It is mainly made
of glass added with adequate foaming agents after heating and
baking in high-temperature tunnel furnace, then annealing and
cooling. Because it well reserves the chemical stability of
inorganic glass, it has the following features: low density, low
thermal conductivity, vapor impermeability, no water absorption,
incombustibility, protection from mould and rat eating, high
mechanical strength but easy to cut and able to bear all kinds of
chemical erosions except the hydrofluoric acid.
Foam glass
(cellular glass), nontoxic in itself, has stable chemical
properties and good heat insulating performance protecting from
deteriorating at a wide temperature range from ultra-low
temperature to high temperature. At the same time, it can protect
from humidity, fire and erosion. It is praised as “permanent heat
insulating material with no need of renewal” because it is not only
safe but also durable in rigor condition of low and cryogenic
temperature, underground, open air, flammability, moisture
sensitivity and even chemical erosion.
Advantages
Foamed glass makes your house inaccessible for temperature shocks
but permeable for vapor so it creates comfortable and stable
conditions for your work and rest. Moreover foamed glass is very
durable material and you don^t need to make wearisome repairs of
insulation. Foamed glass is also good for reconstruction of old
buildings because it is absolutely safe and handy for
use.
The basic
advantages of foam glass deserve more detailed
consideration.

Application
Foam glass
(cellular glass) is applied widely as follows: 1.Chemical Industry：
Reaction equipment, chemical pipes, oil pipes, LNG pipes, LPG
pipes, tank bottoms and insulation projects, etc.2.Architecture:
refrigeratory, ship-building industry, roof heat-preservation,
inside and outside wall heat-preservation, parking lot and
insulation of inner layer of chimney, etc.3.Underground Projects:
subways, underground storerooms and tunnels, etc.4.Others: Military
industries, pumice, air-separator pipes, cold liquid tank bottom
insulation, etc.Characteristics of high Performance foam glass
(cellular glass):
