Building foam glass heat insulation water-proof and fire-proof panel |
Building is closely interconnected with humans’ life. According to statistics, the building energy consumption holds the share of energy consumption 35%, and the refrigeration energy holds nearly 20~25% shares of total energy consumption. Human-beings always pay attention to one-off building investment, and neglect running expenses in using, especially the summer refrigeration cost for long. Increasing the heat insulation performance can effectively improve residential condition and economize cost of energy consumption, so energy-saving for building is one of the tasks urgently needed to be solved.
With the development of architecture, the energy-saving draws more and more attention. Unicellular glass has well heat insulation, sound insulation, water-proof and fire-proof performance. According to the thermodynamic analysis and construction research, together with reasonable heat insulation structure, unicellular glass will become the ideal material for building energy-saving.
It is a kind of light inorganic heat insulation material with strong rigidity. It has the characters of low coefficient of heat conductivity, damp-proof, incombustible, non moldy, high mechanical strength, easy manufacture, anti-chemical corrosion, nontoxic, etc. |

Features of foam glass |
1. Fire-proof
PENGFEI foam glass is a kind of fully harmless fire-proof material that will not burn and cause any toxic gas.
2. Water-proof
PENGFEI foam glass has 100% closed bubble, which makes the moisture penetrability 0.00. It is the only light heat material in the world with 100% water-proof effect, and has reliable heat insulation effect.
3. Weight-proof
Pressive strength（7kg/cm2） of PENGFEI foam glass can burden the load of parking lot, building, depot building, freezer, etc.
4. In-deformation
Expansion shrinkage （9.0×10-6/°C） of PENGFEI foam glass is nearly the lowest in heat insulation material. The dimension stability makes it become the most proper heat insulation and water-proof material.

Water-proof, Fire-proof and heat insulation of wood roof |
PENGFEI foam glass has the character of fully moisture-proof, in addition it has nearly the same linear expansion and shrinkage coefficient, so it will not make the heat insulation material chap. As for the problems of water-proof, fire-proof, insect prevention and bacteria proof of wood structure, PENGFEI foam glass can solve all the problems.
PENGFEI foam glass can reduce the weight of wood-roof structure and avoid deformation.
PENGFEI foam glass is fully harmless and nontoxic material, and it can not burn. |
Water-proof and heat insulation of external facade--external heat insulation |
Renewing of wall: before construction, the surface of wall must be smooth, otherwise it can be constructed right away.
PENGFEI foam glass should be stuck from up to down.
It can not use flint paper to polish PENGFEI foam glass. |
Water-proof and heat insulation of external facade--internal heat insulation |
As the heat insulation material of internal fade, it can effectively reduce the thickness of wall and the weight of building structure and enhance the using areas of the building. |
Heat insulation of terrace |
