Low-E Glass Benefits for South-Facing Baltimore Homes

What South-Facing Windows Put Your Home Through

On a south-facing wall, the sun is not just a view, it is a heat source that shows up in the room every clear day. A little winter warmth is welcome, but the same light that brightens the room can push indoor temperatures up and make the house harder to keep comfortable.

This is where low-E glass earns its keep. Instead of treating all sunlight the same, the glass filters the part that works against comfort and preserves the part that makes the room usable.

Choosing The Right Glass For A South-Facing Room
