Doors Make a Big Difference

Knoxville Exteriors installs 2 different brands of doors that include Andersen Patio Doors and Therma-Tru Entry Doors.

Andersen Patio Doors

Installing Andersen Patio Doors is like Putting Sunscreen on your Home

The Low-E glass in Andersen doors works like sunblock, protecting your home and furniture from ultraviolet (UV) light, protecting expensive fabrics and carpeting, and reducing solar heat gain.
Low-E glass, combined with state-of-the-art weatherproofing design means Andersen patio doors can insulate a room as well or better than the walls that surround them.
And the warranty they carry is unsurpassed.*

Plus they’re beautiful doors!

*Not all warranties are alike. The Andersen Owner-2-Owner™ transferable limited warranty can add resale value to your home, plus Andersen maintains inventories of replacement window and door parts, some from as far back as 50 years.
