How Weatherstripping Improves Window and Door Efficiency

Why Weatherstripping Matters More Than Most Homeowners Realize

Weatherstripping is one of the smallest upgrades in a house, but it can have an outsized effect on comfort and energy use.

If air can move freely around a window or door, the home loses efficiency fast, even when the glass or slab itself is in decent shape.

For homeowners trying to reduce energy bills with new windows Montgomery County, the seal around the unit matters almost as much as the unit itself.

What Weatherstripping Actually Does At The Frame

It is the flexible barrier that helps a frame stay tight without locking the window or door shut.

When To Repair Weatherstripping, And When To Think Bigger
