Our Founding Principles

Quality

The 3 pillars of Technology, People and Quality are the foundation pillars of our existence Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but

also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum

Tempering process increases the strength of the glass many folds, offering a greater resistance to breakage. However, the raw-materials used in the manufacturing of tempered glass are not free from certain defects like nickel-rich contaminants such as stainless steel might be present, and then combine with sulphur to form nickel sulphide inclusions, which put tempered glass at potential risk of spontaneous breakage.

What is Heat Soaked Glass? This glass undergoes rigorous process of heat soaking to ensure higher inherent safety and to avoid any spontaneous breakage of the tempered glass in high traffic areas.


Product Range of Heat Soaked Glass Up to 95% NiS infected panes are usually destroyed at factory itself. Due to inherent safety and security benefits, it is highly recommended for tempered glass to be heat soaked in applications where consequences of breakages are high.

Minimizing NiS Fractures: Making sure that fractures happen within the factory rather than at site after installation.

Applications The use of heat-soaked tempered glass is recommended where the risk of spontaneous breakage would cause difficulty, either from a replacement point of view, or where falling glass fragments may be unsuitable, such as roof or high level glazing, balustrades, screens and high level curtain walling.

STL Sound Transmission Loss

Rw Weighted Sound Reduction Index

The average Sound Transmission Loss is useful for determining the effectiveness of glazed panels to isolate exterior noise (such as traffic) from a building. It is derived from the average of the measured transmission loss at 18 1/3 octave frequency bands between 100Hz and 5000Hz, or 16 bands from 125 to 4000Hz. The average STL is measured in decibels (dB), the higher the average STL figure, the more effective the glazing will be in reducing sound transmission.

The Weighted Sound Reduction Index incorporates frequency modified correction for the human ear’s response. The Rw is reported in dB and and is a composite rating of sound reduction at frequencies from 100 to 5000Hz. Numerically, it is comparable with the STC values but the numbers are in dBA.

STC Sound Transmission Class The average Sound Transmission Class is useful for determining the noise reduction offered by internal building elements such as partitions and walls. It is a measure that relates the sound reduction performance against sounds which normally occur inside a building (such as voices, telephones, music, etc). STC is a numerical class rating and cannot be compared with the STL. It is derived from a best fit curve comparison of a reference STC curve to the insulation curve. The higher the STC rating, the better the overall sound reduction.

PSR Perceived Sound Reduction The percentage by which the human ear detects a lessening in sound pressure or noise is known as the Perceived Sound Reduction. A 10dB reduction in sound pressure level is generally perceived as a halving of the original noise. Sound reduction values are ‘weighted’ and used to calculate the perceived sound reduction as a ratio relative to the Rw for 3mm clear float. The dB difference in the Rw value for a glass type when compared with 3mm float is calculated as a perceived sound reduction percentage. Note: Sound control performance data listed in this publication is derived from the manufacturer’s data, acoustic test results, acoustic modelling software or an estimation based on the above methods.


VLT Visible Light Transmission The percentage of visible light that is transmitted through the glass. The VLT is measured in the 380 780nm wavelength range perpendicular to the surface. The higher the percentage the more daylight. Also known as Tv, Tvis, LT and VT. VLR Visible Light Reflection The percentage of visible light that is reflected by the glass surface, measured in the 380-780nm wavelength range perpendicular to the surface. The VLR can be given as the reflection from the external surface 1 or internal surface 2. The higher the percentage the more reflection. Also known as LR, VR and Rvis. UV Ultraviolet Elimination The percentage of ultraviolet radiation eliminated by the glass, measured over the 290-380 nm wavelength range. The higher the percentage the less UV is transmitted. This value is calculated from the percentage transmission of ultraviolet (Tuv). Therefore UV Elimination = 100 - Tuv. FRC Fading Reduction Coefficient The ratio of fading reduction of a glass type when compared to the fading protection of 3mm clear float. The FRC of 3mm clear float is by definition 1.0 and represents the minimum fading protection offered by standard glazing. The lower the fading reduction coefficient, the better the fading protection offered. The FRC is derived from Damage Weighted Transmission (Tdw-K) data which is a measurement of the fading reduction over the whole solar spectrum, not just ultraviolet. It is ‘weighted’ to include the fact that fading damage occurs from a broad band of solar energy such as infra-red, visible light and ultra-violet. SHGC Solar Heat Gain Coefficient The measure of the total solar energy transmittance entering a building through the glazing as heat gain. It is the total heat transmission of direct solar transmission and that proportion of absorbed radiation that is reradiated into the building from the action of heat absorbing glass. The lower the SHGC the better the glass restricts heat energy transmission. The SHGC is also known as the Solar Factor (SF)or g. SC Shading Coefficient The ratio of the total solar heat gain through a particular glass compared to the total solar heat gain through 3mm clear float glass. (86%) The shading coefficient of 3mm clear float is by definition 1.0 and represents a base glass performance. The lower the shading coefficient the less heat gain and thus more shading is provided by the glass. The shading coefficient is calculated as SC = SHGC / 0.86. WERS Window Efficiency Rating System The complete WERS rates the performance of windows including frames in various defined New Zealand climate zones. For this catalogue star ratings apply to centre of glass only (WERS cog) to compare glass types and a maximum rating of fi ve stars indicates the best performance possible. The stars have been calculated on the WERS Star Rating Approximator for Glass - Version 2. Ratings in stars and half star values are given for as follows with five stars indicating the premium performance:

Winter Heating Star rating is a measure of how easy it is to maintain an average New Zealand home at a comfortably warm living temperature through an average climate-year (although principally in winter). Summer Cooling Star rating is a measure of how easy it is to maintain an average New Zealand home at a comfortably cool living temperature through an average climate-year (although principally in summer). Fading Star rating is a measure of the amount of damaging solar radiation that is able to enter through the glazing, such that a choice can be made about the degree of protection that you wish to give your furnishings and fabrics. A glazing with five stars will not completely eliminate the fading of all furnishings, but significantly reduces the magnitude of the penetrating solar fading energy. Condensation Star rating is a measure of the amount of unwanted condensation that will occur on the room side of the glazing of windows in an average New Zealand home, with 5 stars indicating premium performance with a minimum of winter condensation. Climate Zones Zone 1 represents the top half of the North Island, including Thames from Greater Auckland north. Zone 2 represents the rest of the North Island except for the Volcanic Plateau. Zone 3 represents the South Island and the Volcanic Plateau of the Central North Island. U U Value The U Value is the measure of air to air heat transfer through glass due to the thermal conductance of the glazing and the difference between indoor and outdoor temperatures. It is expressed as W/m2K (Watts per m2 per 1° Kelvin) or W/ m2 °C (1 Kelvin equals 1°C). The U value is a measure of the rate of heat gain or heat loss through the glazing due to environmental differences between outdoor and indoor air. It is measured at the centre of the glass (cog).The lower the U Value the lower the heat transfer, the better the insulation. It is also the inverse of the R Value U=1/R. U Values are determined using a set of weather conditions established by the National Fenestration Rating Council (NFRC) in America. It is possible to modify these conditions and calculate U Values for specific environmental conditions. CF Coolness Factor The Coolness Factor (or luminous efficacy) is the visible light transmission divided by the shading coefficient. CF = VLT / SC. It is a useful means of comparing different glass types in terms of the trade-off between light transmission and heat control in selecting glass. Glass types with a coolness factor of 1 transmit as much light as heat, those with a coolness factor lower than 1 transmit more heat than light and those with a coolness factor greater than 1 transmit more light than heat. R R Value (Total Thermal Resistance) The R Value is the value of the thermal resistance of a building element which is the sum of the surface resistance on each side plus each component of a building element. It is the inverse of the U Value R=1/U and is expressed as m2ºC/W.


Glass Performance & Test Reports Breakage Patterns Annealed float glass does not resist high stresses from the impact of an object. When broken, it shatters into large sharp pieces.

Glazing types and surface positions Single Monolithic

outside

Laminated safety glass has the about the same impact strength resistance as that of annealed float glass (e.g. 6mm = 6.38mm). If broken, glass remains intact on its PVB interlayer and depending on impact shards do not fly out.

Outboard Lite

outside

Toughened safety glass is up to five times stronger than annealed float glass and offers the highest resistance to impact. If broken, the whole panel of glass shatters into small pieces of blunt granules which are relatively safe. Additionally, the shattered glass falls out quite easily.
