Multi pane windows can have 2 to three surfaces coated which effectively block long wave and short wave infrared energy. Short wave protection refers to blocking heat from the sun and acting like a mirror to reflect the energy away from the home. This is super beneficial in the summer months. Long wave protection will reflect the energy already inside your home and reflect/mirror it back inside to prevent energy loss in the winter.
Reduce Energy Consumption and Increase Comfort
Saving money on energy bills is always one of the primary drivers behind the decision to purchase replacement units with low e windows. When you can reduce the number of times per hour your A/C has to kick in, the temperature in your home stays more consistent thereby reducing energy consumption.

Most Popular Questions Regarding Low E Windows
Q: What are low-e windows and how do they work?
A: Low e (emissivity) coatings are microscopic layers of silver oxide. They reflect infrared energy. Emissivity means that it is poor at radiating and releasing thermal energy.
Q: Do low-e windows help reduce energy bills?
A: By reflecting the sun’s energy back from your home, it can’t enter the home and will not contribute to heat gain in the summer. This lightens the load on you A/C.
Q: Are Low-E coatings visible on windows?
A: Low-e coatings are nearly invisible. They do filter out a small amount of natural light thereby reducing glare and UV light that fades carpets and fabrics.
Q: How do low e windows compare to clear glass?
A: Clear glass allows the full UV light from the sun to enter your home and is ineffective at blocking heat gain.
Q: Can you add a low-e coating to existing windows?
A: No. While there are some films available with marginal benefits, low-e coatings are applied at the glass factory using one of two methods: hard coat (applied while glass is still molten) and soft coat (applied in a vacuum chamber). Soft coating is more effective at blocking energy.
