The Most Energy Efficient Window Frame Materials for Maryland Homes

Why Window Frame Material Matters In Maryland

For Maryland homes, the frame matters almost as much as the glazing itself. Because Maryland weather swings from muggy to freezing, the frame has to resist both heat transfer and moisture-related wear.

That is especially true in older Maryland houses, where rough openings may be out of square and existing trim needs to be preserved.
