Safety The Future ThatStandard OptimizesOfPerformance High Performance & Keeps The Glass Noise Down

Eco Cool The Eco Cool range of high performance insulating glasses deliver superb spectral selection, energy saving potential, aesthetic flexibility and appeal. The high performance glass has a multifunctional coating with multilayer stack to meet the defined or desired spectral performance criteria. Coatings have been carefully selected to offer high quality bonding to the glass substrate, along with durability and abrasion resistance.

While viewing through the glass, the neutrality of colours of the surroundings is retained to the maximum possible extent which delivers a natural feel to the viewer.

Available in avariety of colours and also offering excellent properties with a combination of solar control, optimum light transmission/reflection and thermal insulation, Eco Cool Glass renders the exceptional qualities of vibrance and endurance.

The Features of Eco Cool: Variety The different coatings on clear and body tinted glass substrates offer a wide range of colours and reflectivity.

Advantages Choosing Eco Cool Glass can result in significantly reduced air conditioning as well as heating costs without sacrificing clear views and daylight. The enhanced thermal insulating properties lead to warmer glass surface temperatures, reducing cold airflow & condensation in cold weather as well as exterior condensation in hot & humid climates.

Applications Whether employed externally for facades, roof lights and conservatories. Eco Cool Glass provides the solutions architects and planners are seeking in glass design. This offers the ability to combine solar control with sound proofing, insulating or security glass.

Solar Performance The enhanced selectivity guarantees maximum energy savings along with the high visible light transmission. Eco Cool Glass has the capability to selectively block or transmit solar rays according to their wavelength. Most of the heat radiation is reflected while natural daylight is transmitted inside.

Thermal Performance Eco Cool Glass provides improved thermal insulation for low U-values without a second low-e coating and confirms to ECBC 2007 guidelines for energy saving glass in buildings.

Short Lead Times Since Eco Cool Glass can be fabricated locally, lead times for new orders and replacements are much shorter compared to conventional soft coated glass.

Availability The post temperable range of Eco Cool Glass is available in jumbo and lehr end size instandard thickness of 4, 5, 6 and 8 mm. Other thickness or laminated glass is available upon request.

A green building is one which uses less water, optimises energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupants, as compared to a conventional building.

FIELD SALES REPRESENTATIVES We're here to help with design assistance, budget costing, return on investment costing, spec writing and review as well as act as a liaison between architects and glazing contractors. We also work closely with the glazing contractor to offer assistance with initial costs, final pricing negotiations, product information and job site inspections. Just ask.

Glossary Color Rendering Index (CRI) The ability of transmitted daylight through the glazing to portray a variety of colors compared to those seen under daylight without the glazing. Scale is 1 - 100. For instance, a low CRI causes colors to appear washed out, while a high CRI causes colors to appear vibrant and natural. In commercial glass, CRI indicates the effect the specific glass configuration has on the appearance of objects viewed through the glass. Heat gain is heat added to a building interior by radiation, convection or conduction.

Heat Transfer Methods Heat transfer occurs through convection, conduction or radiation (also referred to as "emission"). Convection results from the movement of air due to temperature differences.

For instance, warm air moves in an upward direction and, conversely, cool air moves in a downward direction. Conduction results when energy moves from one object to another.

Radiation, or emission, occurs when heat (energy) can move through space to an object and then is transmitted, reflected or absorbed.

Light to Solar Gain Ratio of the visible light transmittance to the Solar Heat Gain Coefficient. A higher LSG ratio means sunlight entering the room is more efficient for daylighting, especially for summer conditions where more light is desired with less solar gain. This ratio is the measurement used to determine whether the glazing is "spectrally selective."

Low-E Coatings Relatively neutral in appearance, low-E coatings reduce heat gain or loss by reflecting longwave infrared energy (heat) and, therefore decrease the U-Value and improve energy efficiency. Current sputter-coated low-E coatings are multilayered, complex designs engineered to provide high visible light transmission, low visible light reflection and reduce heat transfer.

Relative Heat Gain (RHG) The total heat gain through glass for a specific set of conditions. This value considers indoor/outdoor air temperature differences and the effect of solar radiation.

R-Value A measure of the resistance of the glazing to heat flow. It is determined by dividing the UValue into 1. A higher R-Value indicates better insulating properties of the glazing. R-Value is not typically used as a measurement for glazing products and is referenced here to help understand U-Value.

Shading Coefficient (SC) An alternative measure of the heats gain through glass from solar radiation. Specifically, the shading coefficient is the ratio between the solar heat gain for a particular type of glass and that of double strength clear glass. A lower shading coefficient indicates lower solar heat gain.

Solar Energy Radiant energy from the sun having a wavelength range of 300 to 4000 nm, which includes UV (300 to 380 nm), visible light (380 to780 nm) and near infrared energy (780 to 4000 nm). % Reflectance Out - percentage of incident solar energy directly reflected from the glass back outdoors. % Absorptance - percentage of incident solar energy absorbed into the glass. % Transmittance - percentage of incident solar energy directly transmitted through the glass.

The sum of percent reflectance out + absorptance out + transmittance = 100%. An additional consideration is emission, or emissivity. This refers to the reradiation of absorbed energy that can be emitted toward both the exterior and interior of the building.

Emissivity is controlled through the use of low-emissivity, or low-E coatings.

Solar Heat Gain Coefficient (SHGC) The percent of solar energy incident on the glass that is transferred indoors, both directly and indirectly through the glass. The direct gain portion equals the solar energy transmittance, while the indirect is the fraction of solar incident on the glass that is absorbed and re-radiatedor convected indoors.

Solar/Reflective Coatings Typically, highly reflective coatings that reduce solar heat gain through reflection and absorption. Though very effective at reducing heat gain, visible light transmittance is generally low and U-Values are not as energy efficient as low-E coatings.

Transmittance Percent Percentage of incident ultraviolet energy that is directly transmitted through the glass.

Long-termexposure to UV light may result in fabric and pigment fading, plastic deterioration and changes to the appearance of many types of wood.

UV Ultraviolet radiant energy from the sun having a wavelength range of 300 to 380 nm with airmass of 1.5.

U-Value (U-Factor) A measure of the heat gain or loss through glass due to the difference between indoor & outdoor air temperatures. It is also referred to as the overall coefficient of heat transfer. A lower U-Value indicates better insulating properties. The units are Btu/(hr)(ft2)(째F).
