E-zone Glass®
Thermal Resistant Cyclone Glass
Please note: The products and solutions featured on this page are currently unavailable outside Oceania. Please contact our team to discuss alternative options available in your region.
Specifically developed for thermal performance, energy efficiency and durability, E-zone Glass® is engineered to perform in the most challenging storm conditions. Glasshape has further enhanced its E-Zone® Range of products with the introduction of E-Zone® Plus. This new variant significantly improves the Solar Heat Gain Coefficient in a colour neutral (close to clear) option.
E-Zone® products provide all the benefits of the StormShield® products with the added energy control benefits. E-Zone® products are available in Ultra, Extreme & Plus options. E-zone Glass® cyclone glass is a certified debris impact resistant glazing solution available in multiple thicknesses for different openings throughout Cyclone Regions C and D in Australia and the Pacific.
The pyrolytic process used in the manufacture of E-zone Glass® embeds invisible heat-reflective materials to the glass. This allows light to enter, but reflects much of the inbound heat, increasing comfort. Conversely in cool climates we can configure E-zone Glass® to maximize heat retention.
Additionally, E-zone Glass® has been subjected to a series of hydrostatic pressure tests – taking cyclone resistant glass to a completely new level, setting yet another benchmark as an industry leader. E-zone Glass® is not only serious protection from wind and storm damage but is also flood resistant.
Visible Light Reflectance (VLR)
- Low Emissivity products such as Glasshape’s E-zone Glass have a higher rate of internal reflectivity than standard glass products, due to their high performing metallic coatings. Visible Light Reflectance (VLR) can increase by between 8-15%.
- Consideration for aesthetic preferences and visual expectations should be made prior to selecting Low Emissivity products for thermal and solar control.
- Consideration for visual reflection when the lighting inside is brighter than outside – i.e. nighttime, in cases where the reflection may negatively impact visual clarity through the glass.
- Glasshape would recommend customers check samples in various lighting situations prior to using the product in a project to confirm suitability.

AS/NZS 1170.2:2011 and AS/NZS 1288Window Frames Tested
Certified in wide range of commonly available cyclone rated framing systems including Alspec, Capral, Alutech, AWS and WintecE-zone Glass - Enhanced Features
Glasshape in partnership with Australia’s preeminent Aluminium Window & Door distributors, Alspec, AWS & Capral successfully tested our products to BAL 40 compliance in a range of commercial and domestic window suites. A chart listing these window suites can be found in our Certified Window Frame Systems brochure.
StormShield® products were tested in accordance with AS 1530.8.1:2018 by Warringtonfire and deemed to comply to BAL 40 when glazed in tested window systems. Glasshape is now the only provider of a product that complies with both the Cyclonic Impact requirements & Bushfire Rating (BAL 40) requirements in an annealed cuttable glass product.
Taking cyclone resistant glass to a completely new level, E-zone Glass® has been tested for performance in flood conditions. E-zone Glass® has been hydrostatically tested and certified for resistance against rising flood waters which are prevalent in cyclonic weather. Wind is only one factor that causes extensive damage to buildings and property throughout fierce storms. Rising flood waters up against windows (especially in a shop front) can cause extensive water damage if the window fails. E-zone Glass® is designed to handle water pressures well beyond what is normal for its thickness due to the ultra-robust laminate interlayer between the glass sheets.
Testing & Certification - AS3555.1-2003
Specifically developed to resist excessive wind speeds and penetration from flying debris, E-zone Glass® is a certified debris impact resistant glass ideal for protecting your family, staff and property during cyclones.
The secret is the specially formulated ultra-high grade laminate used in the manufacturing process, which absorbs the impact of the debris without tearing or breaching the window envelope. This means even in the event the glass is damaged by flying storm debris, E-zone Glass® remains weather-tight to protect the structural integrity of the building and ensure the safety of the occupants.
Major insurance companies and Local Shire Councils have approved E-zone Glass® for use in North Western Australia, Queensland, Fiji and other Pacific regions.
Certified to AS/NZS1170.2:2011 (Cyclone Impact Resistance), AS4040.2:1992, AS4040.3:1992 (Static & Cyclic Wind loading) and AS/NZS2208:1996 (Safety glazing materials in buildings), E-zone Glass® ticks all the boxes for compliance and certification.

Australian Wind Speed Regions
Building wind loadings and debris impact loadings are determined by the regional wind speeds specified in the AS/NZS1170.2:2021 standard. The standard has four wind regions in Australia of which regions C and D are classified as cyclonic regions where protection from wind born debris is required.
The building must be engineered to also withstand full negative internal pressure regardless of the glazing system used.
Regions are Marked with letters:
A (0 to 5) – Normal
B (1 to 2) – Intermediate
C – Cyclonic
D – Severe Cyclonic
