THERMAL INSULATION / ENERGY SAVING
Seves glass blocks offer excellent thermal insulating properties while still allowing natural light transmission. When installed using Ezylay Installation Systems, they have been assessed and certified by WERS for both mortar & silicone installation.
Seves glass blocks also offer excellent acoustic properties. Varying acoustic ratings can be achieved by using different types of glass blocks. This makes glass blocks a great solution for blocking noise from busy roads, noisy neighbours, or even under commercial flight paths.
LIGHT TRANSMISSION / CONTROL
Glass blocks can be used to control the amount of light entering a room and also to control the degree of transparency, allowing for both comfort and privacy where required.
Standard, colorless glass blocks offer 80% light transmission, while lower levels can be obtained using color tinted or frosted (etched) glass blocks.
Seves glass blocks are available in a wide variety of designs offering various degrees of privacy, ranging from complete transparency to almost total obscurity.
Light Diffusing or Light Directing glass blocks can also be used to control the amount and direction/angle of light entering a room.
Please consult your Glass Brick Company representative for advice on which design will best suit your project requirements.
The below table shows performance data for selected Seves Glass Blocks. Declaration of performance data sheets are available on request for all Seves Glass Blocks.

Another feature of glass blocks is their ability to meet high security standards. Different glass blocks have varying glass thicknesses and can be installed with varying degrees of reinforcement to provide the strength and security to suit your project needs.
Certain Technology range glass blocks have been subject to ballistic testing for bullet resistance, making them ideal for use in buildings where security is critical.

WIND LOADING / WATER PENETRATION
Glass Brick Company exclusively uses Ezylay Glass Brick Installation Systems for both mortar and silicone installation. Ezylay Installation Systems have been tested and certified for wind loading and water penetration by a NATA approved testing laboratory. Ezylay’s superior framing and reinforcement systems allow even silicone jointed panels to be constructed up to 5 metres wide in external applications. Mortar jointed panels can be constructed to unlimited widths using expansion joints at least every 6 metres. Performance testing data is available on request.
CURVED GLASS BRICK WALLS
Glass bricks can be constructed to form stunning curved walls around stairwells, as internal diving walls, or even as a shower screen. How tight the curve can be constructed depends on the width of the glass brick.

SLIP RESISTANCE – GLASS PAVING
When installing glass paving in trafficable areas, the glass pavers often need to comply with slip resistance requirements. This will most likely require the top of the glass pavers to be sandblasted to ensure they comply. Glass Brick Company have had Seves glass pavers tested and certified by the CSIRO for slip resistance to a rating of R10. Test certificate available on request.
