This glass is a unique combination of two types of Low-E technology. By combining Pilkington Energy Advantage™ Low-E glass with Guardian ClimaGuard 63/31 Low-E glass, Sun is able to obtain a highly effective, energy efficient insulated glass unit that maximizes both the thermal U-factor and the Solar Heat Gain Coefficient. These are the two factors that must have an over-all rating of 0.30 or lower to qualify for the Federal Tax Credit. Sun is pleased to offer this new configuration to bring many of our products into the qualifying range for the Tax Credit.
Hybrid Combination maximizes the U-factor, while maintaining low Solar Heat Gain.
ClimaGuard 63/31 low-E glass from Guardian Industries has a lower U-factor for superior insulating performance during cold nights and a lower solar heat gain coefficient to provide relief from the intense heat of the sun. This combination reduces heating and cooling costs.
Energy Advantage low-E glass from Pilkington, because of its hard-coat properties, is used on the interior (or number 4 surface) of the the I.G. unit. Placing it on this surface improves the over-all U-factor, while retaining the low Solar Heat Gain of the 63/31 glass. The result is a hybrid insulated glass unit with both a low U-factor and a low Solar Heat Gain Coefficient.
Please note, due to the exposure of the hard-coat low-E surface to the interior, certain characteristics of the glass surface must be accommodated. The exposed low-E surface will have a slight surface texture (it is not completely smooth to the touch). Also, under certain lighting conditions and view angles, it will exhibit slight color reflections or perhaps a hazy cast. This is normal for this type of glass. Additionally, special care and cleaning practices must be followed to prevent damage to the coating. See the link to the cleaning instructions.
