Energy-efficient windows and doors reduce heat transfer, minimize drafts, and help maintain consistent indoor temperatures which are key benefits in Denver’s climate.

What Makes a Window or Door “Energy Efficient”?

Low U-Factor and Proper SHGC

High-performance windows and doors use materials that regulate thermal transfer. ENERGY STAR–tested products provide independently verified performance data:

Low-E Glass Coatings

Low-emissivity coatings reduce heat loss in winter and limit heat gain in summer which is ideal for Denver’s weather patterns.

Insulated Frames

Vinyl, fiberglass, and composite frames with built-in thermal breaks perform far better than old, conductive aluminum frames.

Cost vs. Long-Term Savings

Many homeowners wonder whether energy-efficient windows and doors are worth the investment. Here’s the breakdown:
