If your air conditioner is running nonstop and your summer electric bill keeps climbing, your windows may be the hidden culprit. Old, inefficient windows let your cool air escape and force your system to work overtime — here’s why.

1. Air leaks around the frame

Gaps and worn seals let conditioned air slip outside, so your AC never gets a break.

2. Single-pane or aging glass

Older glass conducts heat right into your home, undoing the cooling you’re paying for.

3. No Low-E coating

Without a Low-E layer, summer sun pours heat through the glass and spikes indoor temperatures.

4. Warped or failing materials

Vinyl can expand and contract in the heat, creating drafts that get worse every season.

5. Poor fit

Windows that aren’t sized precisely leave room for energy — and money — to escape.

Our exclusive Fibrex material and ENERGY STAR certified glass options block thermal transfer to keep the cool air in and the heat out, all summer long.
