ProVia EcoLite Patio Doors in St. Louis

ProVia’s EcoLite is the most affordable patio door in the lineup, and it keeps things simple on purpose. It’s a welded-frame, all-vinyl slider with an adjustable-wheel system built for smooth, quiet operation year after year.
A patented U-shape frame design adds flexibility that virtually eliminates seal failures, and a low-E glass coating paired with the Intercept Blackline IG Spacer System cuts heat loss, keeps the glass warmer to the touch, and reduces interior condensation.
Every EcoLite door we install comes from STL Windows and Doors, a ProVia Platinum Dealer serving the entire St. Louis region, with a 10-year workmanship warranty layered on top of what ProVia already provides.
Key Features
Here’s what makes an EcoLite patio door the value pick for St. Louis homes.
All-White Simplicity
Clean white interior and exterior on every EcoLite door, so there’s no color decision to make.
2-Panel, Two Sizes
Built only as a 2-panel slider in two standard sizes, kept simple by design.
Weather-Resistant Vinyl
Low-maintenance, all-vinyl construction built to hold up to St. Louis weather.
Glass Options
Privacy or tinted glass, plus internal grids, to fit the room behind it.
Keylock & Footlock
Optional keylock and footlock add extra security at the threshold.
ECOLITE PATIO DOOR GLASS OPTIONS
Just two glass choices here: clear with grids, or privacy glass if you’d rather block the view entirely. Tinted glass is available too, for cutting down on glare and heat gain.
ECOLITE PATIO DOOR SCREEN OPTIONS
EcoLite ships with a BetterVue fiberglass mesh screen, and three tougher options are there if the standard mesh isn’t enough for how the door gets used.
