Foam Glass

Foam glass is a new kind of inorganic thermal insulating material with a structure of equally closed cells. It is mainly made of glass added with adequate foaming agents after heating and baking in high-temperature tunnel furnace, then annealed. It well reserves the chemical stability of inorganic glass. As a result, 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, nontoxic in itself, has stable chemical properties and good thermal insulating performance protecting from deteriorating at a wide temperature range from cryogenic temperature to high temperature. At the same time, it can protect from humidity, fire and erosion. It is praised as "permanent thermal insulating material with no need of renewal", because it is not only safe but also durable in rigor conditions of low and cryogenic temperature, underground, open air, flammability, moisture sensitivity and even chemical erosion.

Consequently, it is widely applied in permanent projects as heat and cold insulating material, such as in the industries of petroleum, chemical engineering, architecture, refrigerated warehouse, underground project, shipbuilding, national defense and war industry.

In addition, it can be made into chromatic sound-absorbing foam glass if adequately added different metal oxides as foaming agents. It is used as sound absorbing material in cinemas, subways, meeting rooms, workshops with noise, studios and so on.

Product Size:

1.Max. Block Size 610×457×(150-200)mm

2.Other specs can be available as per customers’ requirements
Method of Application:
1. The surface of foam glass roughcast has one layer of thin coat which should be removed before it is used. The surface of plates of finished products need to be cut to the extent of appearing white stripes.
2. It can be processed with tools such as woodworking blades, circular saws, abrasion wheel blades and handsaws.
3. It can be installed after molding with special adhesives of cellular glass-- TN-1 adhesive or FG adhesive
