Turning impossible dreams into exciting realities.

The Ultimate High Wind Zone/Storm and Cyclone-resistant Glass. Ultra light weight, specially designed for large double glazed or single glazed windows.

StormShield®, Glasshape’s all new ultra robust cyclone

resistant and storm glass is a fully certified Grade A

Laminated Safety Glass. StormShield® is designed (by use

of a specially formulated polyacrylic laminate) to resist

penetration from flying debris, and excessive wind speeds

that are present during cyclones. Its ultra-high grade

laminate is designed to allow the glass to expand and

contract up to five times its normal rate before breaking

and once broken remains weathertight without tearing

or breaking the window envelope, thus maintaining

watertightness during and after a storm.

MULTI-LAYERED CYCLONE RESISTANT GLASS - BY GLASSHAPE

Storm Shield®

7.88mm StormShield® has recently been proven to be 30%

stronger than existing 13.88mm cyclone

glass made by other manufacturers.

Also, a world-leading cyclone testing station has rated

7.88mm StormShield® at 5.75kPa SLS Design Pressure

StormShield® benefits at a glance:• StormShield® Can be used in cyclone-prone areas without the need of storm shutters,

thus giving excellent clear vision • Full protection from all types of weather • Will

withstand wind gusts in excess of 511km/h (12.04kPa) when tested to AS4040.2. (10mm

StormShield®) • Excellent noise reduction • Fading protection • High security • Available in all

types of high performance glass and tints to enhance performance characteristics • Tested and

approved to: AS/NZS 2208:1996, AS/NZS 1170.2:2002, AS/4040.3:1992, AS4040.2:1992 • Grade A

Safety Glass for Human Impact NZ4223 and AS1288 • Available in cut to size or stock sheets

Technical Data:Cyclone Resistance

StormShield® has been tested by a fully accredited third

party cyclone testing station and has exceeded the test

described in AS/NZS1170.2:2002, Clause 5.3.2. This test

involves a 4kg piece of timber 100mm x 50mm cross-

section projected at 15m/s at any angle onto the glass.

StormShield® resisted the impact without any penetration.

Wind Resistance

The thinnest panel in the StormShield® range (7.88mm

thick) has been cyclic tested in accordance with AS4040.3

and has a rating of 5.75kpa! Panel size tested was 1800 x

700mm in a steel frame with 19mm edge cover. There were

no adhesives or glues used. This equates to 350 km/h wind

velocity. The 10mm StormShield® panel has a Strength

Limit State Design wind capacity of 6.74kPa! (Approx 381

km/h wind velocity).

Although the chart on the following page can be used for

calculating glass size and StormShield® thicknesses, this is

only a guide from test results and Glasshape recommends

using Wind Design Engineers to help with specific design to

building wind load capacities for individual projects.

This graph should also be read in conjunction with NZS4223

and AS1288 wind loading charts.

Range

StormShield® can be manufactured to incorporate other

high performance coated glass such as Evergreen,

Eclipse, Stopsol and Sunergy to boost the performance

characteristics. Speciality makeups of StormShield®

including tints are recommended to have a Thermal Safety

Assessment on the application.

Glazing

The glazing frame that StormShield® is glazed into is just as

important as the glass itself. A weak frame will dramatically

affect the performance of StormShield®.

For extra strength, aluminium clad steel frames or

aluminium frames with steel inserts are recommended

with a minimum edge cover of 19mm for engineered extra

strength. Glass must be fully glazed on all four sides.

Glazing adhesives are not essential but if used, they must

be a non-acidic cure, non-solvent based silicones that do

not attack Polyacrylic laminates. Glasshape recommends

the use of Dow Corning 995 as a structural sealant.

Where to use:• Windows and door openings in cyclone risk areas

and high wind zones

• Buildings that need to remain habitable

immediately after a storm

• Hotels and Resorts in coastal regions

• Government and communication buildings

• Hospitals

• Households and offices

• Any large window that calls up heavy, thick glass

under the NZS4223: Part 4:2000 as StormShield®

has extremely high wind zone ratings,

while being very thin and light weight

• Ideal in large double glazed units as StormShield®

will dramatically reduce weight and thickness
