Is Low-E Glass on Replacement Windows Worth It?

Natural light is essential in almost every home. It makes the space feel more open and inviting. It also helps eliminate the need for artificial lighting during the day, reducing eyestrain and improving productivity. But usually when you open your home to more natural light that also means increasing solar heat gains. That is where Low-Emissivity (Low-E) glass on replacement windows in Escondido, CA can be a worthy investment.

The Nature of Glass

Glass is a highly emissive material that absorbs and transfers a lot of energy. This is why one pane of untreated glass does very little to protect the home against heat gains and losses. This is not good for insulation or energy bills. That is why double glazed windows are the new standard in the window industry. But to make replacement windows even more efficient manufacturers use Low-E glass.

What is Low-E Glass?

Low-E glass is a windowpane with special coatings of metallic oxides. The metallic layer reflects ultraviolet rays which can damage carpets, fabrics, and furnishings. It also stops the transfer of infrared light to control radiant heat as it leaves or enters the home. This will help keep the home warm in the winter and cool in the summer. The microscopic application is not visible to the naked eye and because it is transparent, it can protect the home while still allowing plenty of natural light to pass through.

Where Do You Apply Low-E Coatings?

There are two main categories for Low-E applications: soft coat and hard coat. The soft coat remains soft and needs additional protection. For this reason, manufacturers usually apply soft coats to the interior surfaces between the glass. There it does not get exposed to the elements and can still help reduce heat transfer.

Hard coats are baked on at high temperatures and are more durable. So manufacturers can apply these coatings to the exterior surfaces of the glass. Unfortunately, they do not have the same level of performance as the soft coats and tend to develop a haze over time.

Manufacturers can apply the metallic layers to different glass surfaces for different results. Applying it to the outermost pane will reflect unwanted heat back outside. This is perfect for warmer climates with plenty of sunshine. Applying it to the innermost pane helps retain heat inside the home. This is great for cooler areas with less sunshine.
