Among the reasons our patio doors are exceptionally energy-efficient is our Low-E4® glass. Our glazing technology reduces dirt buildup, minimizes water spotting, prevents sun damage, and resists breakage while lowering your energy bills.
Thanks to our replacement door designs, you’d experience the huge difference our Low-E4 glass brings to the table, including the following:
At Renewal by Andersen® of Austin, we use our innovative Low-E4 glass packages to capture wonderful views without allowing excessive heat gain. Normally, the biggest consequence of enjoying nature’s beauty from the inside is admitting the sun’s infrared rays, which causes heat. Less energy-efficient patio glass doors offer little protection to block them, raising your indoor temperatures in the process.
You can’t say the same about our hinged and sliding patio doors. Our glass solutions have a spectrally selective, multi-layer low-emissivity coating to send most of the sun’s unwanted radiation away. To put things into perspective, our SmartSun™ glass, our highest-rated option, denies 72% of solar heat that tries to pass through it.
Most exterior doors rely on the frame to insulate because they don’t much glass. On the contrary, the abundance of glass in our products make them resist thermal transfer better. Since our doors have high glass-to-frame ratios, you can optimize the remarkable energy performance of our Low-E4 glazing technology.
In many ways, our doors are just like our windows but with heightened benefits. On top of our cutting-edge Low-E glass technology, we use an argon gas blend for fill and a stainless steel spacer to conduct even less energy. As a result, expect your Renewal by Andersen patio doors to keep wanted heat inside your home.
Our Low-E4 glass are tough on infrared and ultraviolet rays but not on visible light. Despite its high energy performance ratings, it has no effect on the clarity and color of the sunlight. Plus, our sleek door designs promote maximum glass area to frame large views and usher in more sun for daylighting.
