FAQs

What questions do you have about vinyl retrofit windows? Here are some of the questions we here the most.

What are retrofit windows? 

Vinyl retrofit windows (often called insert or pocket windows) are custom-engineered replacement windows designed to slide precisely into your home’s existing window frames. Unlike a full-frame replacement, the original interior trim, exterior siding, and structural frames are left completely intact. The old glass and sashes are simply removed, and the new, high-efficiency vinyl window is anchored directly inside the original opening.

What are the cost savings of retrofit windows?

Retrofit windows are actually significantly less expensive than full-frame replacement windows. Because the labor and materials are significantly less, on average, retrofit windows cost 15% to 30% less overall.

What are the best retrofit windows?

If budget is not an issue, you should look past standard builder-grade vinyl and move into ultra-premium vinyl composites, architectural-grade fiberglass, or European-engineered uPVC (unplasticized PVC). These high-end "insert" retrofit windows offer maximum thermal efficiency, ultra-slim frames (for more glass), and luxury-tier hardware.

If you want the absolute pinnacle of luxury, engineering, and thermal performance, the clear winner is the Andersen A-Series (Architectural Collection).

If you want sleek, ultra-thin frames and the highest boost to your home's resale value, choose Marvin. But if you want the absolute best-performing, heaviest-insulated traditional vinyl window money can buy, the ProVia Endure Series is a great choice.
