Get privacy and light control without exposed blinds with Integral Mini Blind Insulated Glass Units (IGUs) from Liberty Shielding.
Also known as blinds between glass, integral blinds, internal blinds, or enclosed blinds, these units permanently seal adjustable mini blinds inside an insulated glass cavity. The result is a clean, protected privacy system without exposed blind slats that collect dust, require cleaning, or can be easily damaged.
Integral blind IGUs are ideal for hospitals, medical facilities, offices, schools, laboratories, conference rooms, commercial buildings, and other environments where privacy, cleanliness, and adjustable light control are important.
Specialty configurations are also available incorporating Low-E glass, X-ray lead glass, and UL 752 Level 3 bullet resistant glass.

Traditional blinds are installed on the surface of a window, where they are exposed to dust, fingerprints, cleaning chemicals, accidental damage, and everyday wear.
With blinds between glass, the mini blinds are permanently enclosed within the sealed IGU.
This provides the privacy and light-control benefits of conventional blinds while protecting the blind assembly behind glass.
An integral blind IGU consists of two glazing surfaces separated by a sealed cavity containing the blind assembly.
The internal mini blinds can be tilted to control privacy, glare, and visible light without opening the insulated glass unit.
Depending on the selected operating system, the blinds can either:
Tilt Only – Rotate the blind slats between open and closed positions.
Lift & Tilt – Raise or lower the blinds in addition to adjusting the angle of the slats.
Because the blinds remain enclosed within the glass, the user can control them from outside the unit without directly touching the blind assembly.
Integral mini blinds provide substantially more control than fixed privacy glass.
When open, the blinds allow natural light and visibility through the glass. As the blades are tilted closed, visible light and visibility are progressively reduced.
Depending on blind position and glass configuration, visible light transmission can range from approximately 82% down to approximately 1%.
This allows a single glass unit to transition between:
This flexibility makes internal blinds particularly useful in spaces where privacy requirements change throughout the day.
Blinds between glass are particularly well suited for healthcare environments.
Traditional exposed blinds can collect dust and require individual slats to be cleaned. They can also be damaged or contaminated through frequent contact.
Integral blinds eliminate exposed blind surfaces by permanently enclosing the blind assembly inside the glass.
This makes them an excellent solution for:
The exterior glass surfaces remain smooth and accessible for routine cleaning while the blind assembly stays protected inside the sealed unit.
Internal blinds are also an excellent solution for office windows, conference rooms, classrooms, and commercial interior partitions.
They provide instant privacy without requiring curtains, shades, or exposed blinds.
Common commercial applications include:
Liberty Shielding offers several blinds-between-glass configurations, allowing the IGU to provide additional performance beyond privacy and light control.

| Level 3 Ballistic / Clear Tempered | 2.3" | Privacy + ballistic protection | High-security facilities |
Choose the operating system that best matches how the window will be used.
The Tilt Only configuration allows the mini blind slats to rotate from open to closed.
This provides adjustable privacy and light control while keeping the blind at a fixed vertical position.
Available controls include:
The Lift & Tilt configuration provides greater flexibility by allowing the blinds to be both raised/lowered and tilted.
This allows users to completely expose the viewing area when desired and lower the blinds when privacy is required.
Available control:
Wand and cord operating configurations are available with ADA-compliant options, making them suitable for applications requiring accessible operation.
Choose the location of the blind operator according to the installation and accessibility requirements of the window.
Available locations:
Consider surrounding walls, cabinetry, equipment, furniture, and accessibility requirements when selecting operator placement.
Three standard mini blind blade colors are available:
| Color | Color Code |
|---|---|
| White | S102 |
| Cream | S149 |
| Silver | S157 |
Standard-color units typically have a 4–6 week lead time.
Integral mini blind IGUs are custom manufactured according to the required dimensions.
Not every width and height combination within these ranges can be manufactured. Maximum allowable dimensions depend on the glass configuration, blind system, aspect ratio, overall unit size, and other manufacturing limitations.
The available configuration should be verified for unusually large, narrow, or specialty-sized units.
Traditional blinds can provide excellent privacy, but their exposed construction creates several disadvantages.
| Blinds Between Glass | Traditional Blinds | |
|---|---|---|
| Blind Cleaning | Enclosed; no routine blind cleaning | Slats require cleaning |
| Protection from Damage | Protected behind glass | Exposed |
| Privacy Control | Adjustable | Adjustable |
| Light Control | Adjustable | Adjustable |
| Appearance | Integrated into glazing | Surface mounted |
| Healthcare Use | Excellent for clean environments | Exposed surfaces collect dust |
| Specialty Glass | Can integrate X-ray, Low-E & ballistic glass | Separate from glazing |
For hospitals, laboratories, schools, and high-traffic commercial spaces, enclosing the blinds inside the glass provides a particularly clean and durable solution.
Privacy glass and internal blinds solve similar problems in different ways.
Frosted, etched, or obscure glass provides permanent privacy. Once installed, the level of visibility generally cannot be changed.
Integral blinds provide adjustable privacy.
Open the blinds when visibility and natural light are desired, partially close them for glare control, or close them completely when privacy is needed.
For rooms where privacy requirements change throughout the day, blinds between glass provide substantially greater flexibility.
When combined with Low-E glass, integral blind IGUs can help improve the thermal performance of exterior glazing.
The blinds can also be adjusted to reduce direct sunlight, glare, and solar heat entering the building.
Benefits can include:
Actual thermal performance depends on the complete glass configuration and building assembly.
Blinds between glass are mini blinds permanently enclosed within the sealed cavity of an insulated glass unit. The blinds can be operated externally while remaining protected inside the glass.
The blind assembly itself is sealed inside the IGU and therefore does not require routine dusting or cleaning. Only the accessible exterior glass surfaces require normal cleaning.
