What is ClimaGuard glass?
Typically used in windows, conservatories, structural glazing, facades and curtain walls, Guardian ClimaGuard® A+ is a new thermal insulating glass for double and triple glazed insulating units that meets the highest performance requirements in terms of transparency and solar heat gain.
What is Low-E glass U value?
The lower the emissivity of the glazing, the lower the resulting U-value and using low-E secondary glazing a U-value of 1.6 is achievable. This not only reduces energy usage and the buildings carbon footprint but the embedded carbon in the original window is retained.
What is Low-E glass insulation?
Low-E stands for “low emissivity”. Low-E windows contain glass that has been coated in invisible layers of metallic oxide. This coating allows natural light to enter the home while deflecting UV rays and infrared light back out into the environment.
How is Low-E glass made?
Low-e windows are made two ways, one is a “soft coat” Low-E which is made by applying the coating in a process called sputtering, where atoms are ejected from a solid target by bombarding the target with energetic particles, to the already manufactured glass. This process applies a film of silver to the glass.
What is RLE glass?
This product is intended for use in heating-dominated climates, typically on the #3 surface to maximize collection and retention of solar energy. Solar Control Low-E – Solar Control Low-E Glass is intended to block solar heat gain. Our product is Guardian ClimaGuard RLE 71/38 available in 1/8” thickness.
What is impact resistant glazing?
Impact-resistant glass is created by use of a safety glaze for laminated glass. This type of glass is created by bonding together two or more panes of glass with a thin clear film between the panes. The thickness of this film can range, as can the UV tint or color.
Does Low E glass help in winter?
If you live in an extremely cold climate, the hard-coat Low-E glass may be an option for you, because it allows some of the sun’s short-wave infrared energy to pass through the glass. This helps to heat your home in the winter and allows the glass to reflect the interior long-wave heat energy back inside.
How effective is low E glass?
If you live in cold, northern climates, Low E coatings can be applied to stop heat from escaping. And if you live in warm, southern climates, Low E coatings are effective at blocking the heat from entering your home. So really, Low E glass windows can be a sound investment regardless of where you live.
How long does Low-E coating last?
five to 10 years
Weaver said that, based on what he has been told, “the newer low-e coatings are much more durable and more securely bonded to the glass than the older-generation low-e’s.” He said the sealant on the glass should last five to 10 years, and the coatings should outlast that by several years.
Is Low-E glass good?
Low E glass makes your home more energy efficient, potentially saving you money on your heating bills, and performs better than standard double glazing.
