Old windows are often a major source of heat loss and uncomfortable drafts. Over time, weather seals break down, frames warp, and gaps form—especially in older wood or aluminum models.
New windows tackle these issues in several ways:
* Tight Seals: Modern weatherstripping and compression seals prevent air leaks around sashes and frames.
* Advanced Frame Materials: Vinyl, fiberglass, and composite frames don’t warp or shrink like old wood frames, keeping a snug fit.
* Multi-Pane Construction: Double and triple-pane windows with gas fills add extra layers of insulation.
* Better Installation Techniques: Professional installation ensures windows are properly sealed and level—no gaps, no air leaks.
