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 window?
