Vinyl double hung windows, explained.
Vinyl double hung windows from Puro Windows are NFRC-certified PuroCima vinyl units built to your sizes and supplied factory-direct to builders across Washington, Oregon and California. Best for traditional elevations, upper floors and rooms that need top-and-bottom ventilation.
Both sashes of the PuroCima double hung slide and tilt in, so warm air can leave through the top while fresh air comes in at the bottom, and every pane can be cleaned from inside.
It suits classic and farmhouse elevations and upper floors where outside cleaning is hard.
Every order uses a certified glass package that meets the Washington State Energy Code (U-factor 0.30 or lower). Factory-direct, builders typically save around 35% on the window package; plan on three and a half to four months from order to site.
