1. You get more bang for your buck with storm windows if you live in a colder climate. Keeping heat in and drafts out adds up in energy savings.

In warm climates, storm windows’ benefits are more limited unless they’re made of reflective glass that deflects the sun’s rays, says Adam Winter, co-founder of Recurve, a San Francisco company that does home energy audits and green remodeling.

2. Storm windows may not provide as much of a return at resale, says Mark Meshulam, author of the Chicago Window Expert blog:

• Not as attractive as replacement windows.

• Less convenient since you need to open two windows to get fresh air.

• More prone to moisture problems.

Vinyl replacement windows recoup about 68% of their cost at resale, according to Remodeling Magazine’s 2011-12 Cost vs. Value Report. The magazine doesn’t track storm windows.
