Energy Savings from New Windows in Baltimore Climate Zone 4A

How Baltimore Weather Exposes Weak Windows

In Baltimore, windows have to handle humid heat, cold snaps, and the kind of seasonal change that shows up fast in drafty older houses.

That matters because windows are not just glass, they are part of the thermal envelope.

Rowhomes, twins, and older detached homes often have original openings that were never designed for today's energy expectations.

What New Windows Actually Save

Energy efficient windows for Maryland climate zone 4A help by cutting drafts, slowing heat transfer, and stabilizing indoor temperatures.

Low-E coatings reflect heat in the right direction for the season, while double or triple glazing adds resistance to heat flow.

• Window surfaces are less likely to sweat in the wrong conditions.

That said, savings are not identical from house to house.

Air sealing, attic insulation, and storm doors can all affect the final result.
