Six certified vinyl lines, custom to your project.

Factory-direct vinyl windows for builders and developers

Puro Windows supplies the full range of NFRC-certified vinyl windows a builder needs to complete a home, a townhome community or a multifamily development - single hung, double hung, horizontal sliders, crank-out casements, fixed picture windows and sliding patio doors. Every unit in our PuroCima series is built to your exact sizes, glazed with double-pane Low-E glass and argon fill, and matched to the certified glass package your project needs to pass Washington code.

Single hung and double hung vinyl windows

Our vinyl single hung and double hung windows tilt in for easy cleaning, use reinforced vinyl frames for structural strength, and carry U-factors from 0.24 to 0.45 depending on the certified glass package selected. They are the workhorse windows for most residential elevations and are available in white, black, and dual-tone (black exterior / white interior).

Casement, slider and picture windows

The PuroCima casement swings outward on a smooth crank handle for maximum ventilation and a tight seal, with U-factors as low as 0.28. Horizontal sliders glide on a reinforced track for wide openings, and fixed picture windows maximize glass area and daylight while hitting U-factors as low as 0.23 - ideal where energy performance matters most.

Sliding patio doors

PuroCima vinyl sliding patio doors give you full-view glass with Low-E performance and the same certified quality as the window line, so entire openings can be specified from a single supplier.

Certified and matched to Washington energy code

Every product is NFRC certified and AAMA compliant. For each order we select the exact certified glass package that meets the Washington State Energy Code requirement of a 0.30 U-factor or lower, so your inspector finds it in the national directory and it passes on the first walk-through. Because we supply factory-direct and cut every middleman markup, builders routinely save around 35% on the window package versus a local distributor - without giving up certification or quality. Send us your window schedule and we come back with product options and factory-direct pricing.
