NEWPRO Windows vs Vinyl Windows

NEWPRO Max Series windows feature a fully welded construction to ensure stability, strength and years of long-lasting performance. Compared to traditional vinyl windows, NEWPRO windows are up to 140% stronger and are a better insulator for your home by 214%.

The major problems with Vinyl:

• Structurally weak due to their hollow frames

• Sensitive To temperature fluctuations that New England experiences, especially if the vinyl window was cheap – the quality of the vinyl can be uncertain with many “low price” replacement windows

• Sagging and warping over time because of temperature changes, which make vinyl windows hard to open and close.

Are NEWPRO Windows the Best Windows?

Our windows have changed over the years as technology and manufacturing has improved. But our main mission for our windows hasn’t changed. NEWPRO wants to deliver the best New England window and window technology possible. Our windows aren’t built to compete with our window companies, our windows are built to replace them.

NEWPRO Windows feature:

  • Fully welded construction means solid, stable and durable windows for years to come!
  • The pleasing appearance of wood with a butt joint
  • Double & Triple-pane glass options
  • Sloped, solid sill with no weep holes for proper drainage without allowing water penetration
  • Seven-point compression seal for the best insulation, draft-protection, and energy-efficiency.
  • Compound tension balancing system so our windows are easy to clean and operate.
  • Solid sashes and frames for maximum durability, strength, and insulation.
  • Composite material means no warping, no decay and no insects in sight!
