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.

SOUND INSULATION

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.

SECURITY

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.

Residential applications:

Entry sidelights
Garage window
Storage area window
Enclosing balconies/entertaining areas

Commercial applications:

Banks
Police stations
Military establishments
Correctional facilities

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.

Glass Block size	Minimum internal radius
190x90x80	650mm
115x115x80	650mm
240x115x80	650mm
190x190x80	1050mm
240x240x80	1350mm

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.
