Insulating Glass Retrofit IGR


Easily Upgrade Operable and Non-Operable Windows and Curtain Walls from the Exterior or Interior Without Replacement
Less is More
Reuse, retrofit, and upcycle. Don't replace.
The concept is simple. The innovation is in how it's done.
Materials
By preserving and upcycling the existing glazing system, we use ~70% fewer materials vs. window replacement, eliminating the cost of demolition and disposal of useful materials into landfills.
Time
Our low-carbon retrofits are pre-fabricated off-site for quality and ease of installation, enabling us to upgrade your facades and windows in no time and cut installation costs by up to 80%.
Money
With no business and occupant disruptions and a faster installation process that requires fewer materials, INOVUES is fully cost-effective solution with up to 10x faster payback and higher ROI.
IGR Key Features & Benefits

Unlike traditional solutions, INOVUES patent-pending breathable system passively vents, eliminating excessive heat and moisture buildup in the insulating cavity, without allowing dirt and dust.
Installs easily and quickly from the interior or exterior, providing minimal disruption to occupants and downtime to operations.


No reduction of daylight opening maintains view to the outdoors and provides clean aesthetics.
Interior IGR retrofit of single-glazed
operable windows, transforming
them into double-glazed without replacement. Or from double to triple pane.

INOVUES' non-invasive facade and window retrofit solutions provide the same benefits of window replacement at a fraction of the cost and without disrupting building operations and occupants.
Adaptable System
Works with most windows and curtain walls as an exterior or interior retrofit.
Superior Window Performance
Turns inefficient single- and double-pane windows into high-performing multi-pane systems with up to 10x the insulating value.

Green Retrofit
Provides points towards green building certifications & increases building efficiency ratings.
Non-Intrusive & Non-Disruptive
No removal, replacement, drilling, or alterations required. No building disruption, damage, or debris.
Great Energy Savings
Up to 40% reduction in energy consumption and peak heating and cooling loads.
Easy Financing Options
With no upfront costs to building owners using PACE or through INOVUES or ESCOs.

Cost-Effective with Fast Payback
A fraction of the cost of window replacement with up to 10x faster payback period.
Tested Performance
Validated by a leading independent testing facility per industry standards.
Maintain or Enhance Appearance
Without altering the architectural identity or historic characteristics of the building.
IGR Performance

2-10x added insulation
Up to 40% energy savings
65%+ outside noise reduction

U-Value, Center-of-Glass (CoG) R-Value, Solar Heat Gain Coefficient (SHGC), and Visible Light Transmittance (VLT) calculated using methods set by the National Fenestration Ratings Council (NFRC) and the Attachments Energy Rating Council (AERC), together with the industry-standard WINDOW 7.8 and THERM 7.8 software by the Lawrence Berkeley National Laboratory (LBNL). U-value / R-value measures the insulating properties of a window. They are reciprocal: a lower U-value / higher R-value indicates better insulation. SHGC measures the amount of solar heat that enters the building through the glass. VLT measures the amount of visible light that passes through the glass — higher VLT generally translates to brighter, naturally lit interiors.
