Modern Energy and Acoustic Performance for Legacy Windows
Achieve modern energy and acoustic standards in existing buildings without the cost, disruption, or aesthetic compromise of window replacement. IndowPRO is the engineered secondary glazing system that makes high-performance retrofits feasible.
Historic federal office building upgraded with R-16 Vacuum Insulated Glass for exceptional energy savings.
The Retrofit Challenge: Performance vs. Irreplaceable Character
Project designers are often challenged to improve energy efficiency and meet client demands for comfort and quiet, while preserving building aesthetics. Full window replacement is often too destructive and expensive, forbidden by historic preservation rules, or needlessly damaging to original construction. IndowPRO elegantly solves this dilemma.
Uncompromising Performance
Engineer the building envelope to exceptional standards. The IndowPRO frame is a platform for advanced glazings, from Vacuum Insulated Glass (VIG) for thermal performance (U-values as low as 0.125) to laminated acoustic glass for superior sound attenuation (STC ratings of 50+). All performance data is validated through third-party modeling and testing.

CLEAN AESTHETIC SUSTAINS BUILDING INTEGRITY
The IndowPRO system features a clean, low-profile frame and custom Cosmetic Cladding that creates a finished, fully-integrated look. Because our system is non-destructive and fully reversible, it's ideal for historic preservation.
Color-Matching to Your Specification. Frame cladding can be matched to any Pantone color to seamlessly blend with existing interior designs.
SEAMLESS PROJECT LOGISTICS
Our system is engineered to solve the most difficult part of retrofits: logistics and installation. Frames ship knocked-down for easy site logistics and are designed to ensure a reliable, airtight fit even in out-of-square openings. The Indow system dramatically reduces measurement errors, installation delays, and costly callbacks.
