How to Insulate Windows for Winter in Tennessee

Start With The Source Of The Draft

Before you spend time sealing glass, take a few minutes to figure out where the draft is entering.

In Tennessee, winter weather often swings from damp and mild to sharp cold, so a small leak can feel much worse on a windy night.

Run your hand around the trim on a breezy day, then check the bottom corners, the meeting rail on double-hung units, and the lock area.

If you see condensation between the panes, that is a different issue from a simple draft, and no amount of caulk will fix the failed seal inside the glass unit.

An experienced window replacement company can confirm whether the frame, sash, or glass is the real source of the draft.

Low-Cost Ways To Winterize Windows
