InstallerSunroom WindowsProVia, installed by XPRT.
ProVia is an American manufacturer that builds windows, doors, and other exterior products to order, with a reputation as a professional-class brand rather than a stock-shelf one. Its vinyl windows are made to size for each opening, which suits the custom nature of an XPRT sunroom well. When a covered space becomes a conditioned room, made-to-order glass lets the openings be sized and specified for exactly how that room will be used.
What distinguishes ProVia is a made-to-order approach and a focus on energy performance. Its vinyl windows come in the operating styles a sunroom needs — double-hung, casement, sliding, and picture — with insulated, low-E glass packages and ENERGY STAR-qualified configurations available. Because each window is built for its opening rather than pulled from stock sizes, a sunroom can be glazed precisely, matching every operable and fixed unit to the room's exposure and airflow.
Why have XPRT install it
A made-to-order window still depends on the opening it lands in. XPRT frames each opening square and to size, flashes and seals it against wind-driven rain, and insulates the surrounding wall so the sunroom holds temperature year-round. Even the best window will leak or sweat in an unflashed, out-of-square opening. One accountable team frames, glazes, insulates, and finishes the room, pulled under permit where required and backed by a local warranty.

Common questions
Rather than choosing from a handful of stock sizes, each ProVia window is built to fit its specific opening. For a custom sunroom, that means the glass is sized to the design instead of the design bending around the glass. We measure and specify each opening as part of the build.
ProVia offers insulated glass with low-E coatings and ENERGY STAR-qualified configurations, which reduce solar heat gain on the sun-facing walls that matter most here. We combine the right glass with proper wall insulation and sealing so the room stays comfortable rather than relying on the windows alone.
ProVia builds windows and doors, and a sunroom typically needs both — an entry or patio door alongside the glazing. We frame, flash, and finish each opening to the same standard so the whole room is weathertight. One team is responsible for how it all fits together.
