Physical Properties of Glass Blocks
The following information is based on a typical **0x**0x*0mm clear glass block. Glass brick
Composition : Silica-sand, soda ash, calcium.
Fusion is obtained at approximately ***0OC.   Light Transmission
Clear **0x**0x*0 = *0%
Coloured **0x**0x*0 = *0%   Thermal Transmission
Average value = 2.9 W/m² °C : Single Wall.   Impact Strength
*2.0 N/mm - Tested using *0kg sand bag and steel ball bearings.   Sound Transmissions
Rw = *2dB depending on frequency.
LIGHT TRANSMISSION may depend on patterns, shapes, finishes and colours. As an example a colourless block DT **0 x **0 x *0 generally gives light transmission of approximately *0%. A coloured block DT Nordica **0 x **0 x *0 gave a result of approximately *0%.
THERMAL INSULATION is equal to that achieved by standard double glazing. Larger blocks give better thermal insulation than smaller blocks.
SOUND INSULATION Tests indicate the certified sound insulation to be *0 dB at **0 Hz for **0 x **0 x *0 and **0 x **0 x *0 blocks.
FIRE RESISTANCE Certain glass blockshave been certified in Australia as "FIRE RATED". Two categories are available - *0 minute or *0 minute. Special installation methods are required for such panels - please contact us for more detailed information about glass brick.
INTERNAL PRESSURE of glass blocksis lower than atmospheric pressure. In the event of breakage they tend to implode - a safety aspect. Condensation occurs at approximately **0ºC
NON-LOAD BEARING Generally glass blocksare not to be used in load bearing capacities. They should be installed independent of the surrounding structure and are only capable of sustaining their own weight together with horizontal loads generated by wind and impact.
PANEL DIMENSIONS should be limited. Height 6m maximum, Length 7.5m maximum with total panel area limited to *5m2
