This technical information is based on our Solaris glassbricks.

Solaris glass brick walls built with bricks in the 190mm x 190mm x 80mm format are considered to be fire resistant.  Fire resistance tests were as follows:

    Fire resistance class G60 (fire resistance up to 60 minutes) for one wall  80mm thick.

    Fire resistance class G120 (fire resistance up to 120 minutes) for two walls 80mm thick. 

The building materials glass, cement mortar, and reinforcing steel are Class A-1 non-combustible building materials. The individual glass brick surface area used in the fire test (1850mm x 1850mm) must not be exceeded.

  

Solaris glass brick walls will help reduce the overheating of interior spaces caused by the penetration of sunlight during the summer months, while also permitting the low-lying winter sun to make a maximum contribution to room heating.

Glass brick walls meet the requirements of the building code regarding energy-saving thermal insulation on buildings with normal indoor temperature. The thermal conductivity coefficient of glass bricks windows is comparable with the property in normal thermopane double glazing.

A 1/r heat transmission resistance of glass brick walls and a thermal conductivity coefficient of k depend on the dimension of the glass bricks and the joining material.

The degree of glass brick transparency on walls can be adjusted by varying the design of the individual glass brick. Whatever the requirements, virtually any degree of visibility protection is possible: from clear view glass bricks with plane parallel surfaces providing transparency from the inside without major distortions, to decorative bricks which make object recognition difficult, all the way to glass bricks which only produce a diffuse light and do not permit any form recognition.

The special BSH20 glass brick is identical with a normal glass brick, but when subjected to triple firing as specified in DIN 52 290/Z, it meets the requirements of classification C 5-SA, the highest level of bullet resistance in glass. Single-shell glass brick elements will provide bullet resistance classification     C 3-SA on single firing, and C 2-SA for triple firing. Double-shell glass brick elements provide bullet resistance classification C 5-SA on triple firing.

 

The efficiency of glass brick walls with high level of burglar-proofing can be vastly improved by selecting specific glass brick sizes, joint widths and mortar joint reinforcements. Resistance classification WK10 is provided by glass bricks up to 240mm x 240mm, and resistance WK60 is provided by glass bricks with dimension 190mm x 190mm, presupposing a cross-wise reinforcement of the mortar joints with special steel.

Acoustic insulation rating R_w varies according to the glass brick format used in a wall constructed with Solaris glass bricks. The average value is 41dB.
