Builders and homeowners working with a $400K to $900K SIP build budget who want windows that perform well and fit the build correctly.
You're focused on getting the best window for your climate and your panel system. You want someone who will review your plans, coordinate with your panel manufacturer, and make sure the windows show up ready to install.
You want the process to be simple, the spec to be right, and the price to be fair.
This is the spec that delivers performance per dollar without compromise. It's what we recommend when budget and performance are your highest priority.
ProVia Endure windows are built with color-retention vinyl in a wide range of colors, with thermal reinforcements in the frame. Energy Star certified across all climate zones.
ProVia Endure isn't a stripped-down product line. It's a professional-class window system with a wide range of design options, styles, and finishes, so "best value" doesn't mean settling.
Double hung, single hung, casement, awning, slider, picture, hopper, and shaped windows. Plus bay, bow, and garden window configurations.
Choose from vinyl, laminate wood-grain interiors, or factory-applied paint in dozens of standard and custom colors, including full Coal Black interior and exterior.
ComforTech insulated glass with low-E and argon fill is standard. Upgrade to triple-pane, tinted glass, privacy glass, decorative art glass, or internal blinds.
Lifetime transferable warranty on the window unit, insulated glass, hardware, screens, and even glass breakage. SunShield vinyl never needs painting and resists rot, insects, and UV damage.
We begin every project with window packages that meet Energy Star certification for your region of the country. After reviewing your construction plans and talking through your preferences, we'll recommend a window package that lets your SIP home perform to its full potential.
| Climate Zone | U-Factor | Solar Heat Gain Coef. |
|---|---|---|
| Northern | ≤ 0.22 | ≥ 0.17 |
| North-Central | ≤ 0.25 | ≤ 0.40 |
| South-Central | ≤ 0.28 | ≤ 0.23 |
| Southern | ≤ 0.32 | ≤ 0.23 |
Prescriptive requirements per Energy Star
Every SIP panel is custom manufactured to fit your home. The rough openings, the wall thickness, the structural loads. Nothing is off the shelf. Your windows shouldn't be either.
We work hand in glove with panel manufacturers to make sure that every window matches the SIP panel exactly. That means precise rough opening dimensions, the right frame depth for your wall assembly, and air-seal details that actually work with the panel edge, not against it.
The result: easier installation for your builder, a tighter envelope on day one, and a home where the window isn't the least efficient part of the system. In a SIP home performing at R-28 to R-40, a mismatched window can cancel out the very advantages you're paying for. We make sure that doesn't happen.
Every window is coordinated with your panel manufacturer's rough opening specs. No guesswork, no field adjustments, no costly rework on site.
When windows arrive sized to the panel, your builder spends less time shimming, adjusting, and troubleshooting. The install goes faster and the seal goes in right the first time.
Your SIP walls are engineered to perform. We make sure the windows match that standard so the envelope works as a system, not a collection of compromises.
We handle the spec review, the manufacturer coordination, and the supply logistics. You get a single window package, specced correctly, delivered on your timeline.
For a 2,400 sq ft SIP home with typical window count (24–28 openings), installed cost typically ranges from $18,000 to $28,000 depending on size, configuration, and region.
This is the performance-per-dollar sweet spot. You're not paying for brand prestige or design customization. You're paying for a window that solves the envelope problem.
