Best Materials for Window Frames in Maryland’s Humid Climate

In a humid climate like Maryland's, the frame material matters almost as much as the glass package. Once a frame starts taking on water or moving out of square, you get drafts, sticking sashes, and gaps that shortchange both comfort and efficiency.

What Maryland Weather Does To Window Frames

In Baltimore and other parts of the state, window frames also have to stand up to repeated opening and closing, occasional salt exposure near the water, and long-term UV exposure on sunny elevations.

It affects how long the window stays square, how often it needs maintenance, and how well it keeps out air and moisture.

The Main Frame Materials And How They Perform

Each one has strengths, but they do not age the same way in humidity.

Vinyl Is The Low-Maintenance Baseline

Compared with wood, it asks for far less maintenance and tends to keep its shape better over time.

Wood can be repaired, detailed, and painted to suit older architecture better than most other materials.

Details That Matter More Than The Brochure
