Integral Blinds – Venetian blinds in a double glazed unit
Are you tired of constantly dusting traditional window dressings? Discover how integral venetian blinds fit completely inside your double glazing, offering perfect privacy and light control without any of the maintenance.
What exactly are integral blinds? Integral blinds, sometimes referred to as interstitial blinds, are beautifully crafted venetian or pleated blinds permanently installed entirely between the two glass panes of a sealed double-glazed unit. Because they are safely enclosed within this hermetic seal, they remain completely protected from airborne dust, household moisture, and accidental damage. Consequently, they never need cleaning. Furthermore, you can effortlessly operate these blinds using a discreet sliding magnet system or an automated electronic control, securely allowing you to adjust privacy and solar glare without compromising the thermal efficiency of the window.
✨ Zero Maintenance
Because the blinds are safely sealed inside the glass cavity, they never collect household dust or moisture. You will never have to clean a blind again.
🧲 Magnetic Control
The system operates smoothly via an external magnetic slider or an automated motor, allowing you to tilt, raise, and lower the blinds effortlessly.
🛡️ Complete Protection
They provide the ultimate protection from intense solar glare and heat while offering complete privacy for street-facing rooms and modern bathrooms.

Allowing natural sunlight to flow through large windows, modern bifold doors, and elegant roof lanterns is an obvious structural benefit to any room. However, depending directly upon the specific aspect of the property, there frequently arises an immediate need for complete privacy or shade.
Perhaps your primary living room window faces directly onto a busy public street, or you require absolute privacy for a ground-floor bathroom. Traditional curtains and hanging blinds certainly provide shade, but they quickly accumulate heavy dust, easily tangle, and frequently get damaged by pets or children. This is precisely where integral blinds represent a significant technological upgrade.
1. Interactive Tool: Retrofit Compatibility Checker
Are you hoping to securely install integral blinds into your current window frames without replacing the whole window? Answer the two quick questions below to verify your structural compatibility.
2. What Are Integral Blinds?
Venetian-style blinds—frequently known across the glazing industry as integrated blinds or interstitial blinds—are meticulously installed securely between the two heavy glass sheets directly inside a sealed double-glazed unit.
Because they safely exist entirely within this sealed environment, you receive the absolute ultimate protection from the blistering heat and glare of the sun, while simultaneously guaranteeing they stay perfectly clean forever.
How Do You Actually Control Them?
Because the actual blind is sealed safely behind a thick sheet of glass, you cannot physically touch the cords. Instead, the system is securely operated by a highly advanced external magnetic slider.
This discreet magnet sits neatly on the internal face of your window. By smoothly sliding it up and down, the corresponding internal magnets seamlessly open, close (tilt), and completely raise or lower the aluminium blind. Consequently, this brilliant engineering means the blind can be easily controlled without absolutely any need to compromise the hermetic, airtight seal of the double glazing.
3. The Core Advantages of Internal Glass Blinds
Why Choose Interstitial Blinds?
Zero Cleaning
Because they are permanently sealed inside the glass cavity, integral blinds remain flawlessly clean and entirely protected from household dirt, cooking grease, and bathroom moisture.
Solar Control
They provide exceptional control over the amount of light entering the room. You can actively angle the internal Venetian blades directly toward the sun to eliminate screen glare.
Sleek Aesthetics
They completely remove the need for bulky curtains or dangling, unsafe cords. They deliver a highly modern, incredibly neat appearance available in a massive choice of elegant colours.
4. Can You Fit Integral Blinds to Existing Windows?
The short answer is normally yes, but it completely depends entirely upon the specific age and structural profile of your existing window frames.
| Structural Factor | Technical Consideration |
|---|---|
| The Age of Your Glazing | If you possess glazing that is over 10-15 years old, it is highly worth seeking the professional advice of a reputable installer. Older frames frequently lack the physical depth required to house the thicker glass. |
| The Unit Thickness | Modern double glazing should naturally be fitted with a robust 28mm unit. Most integral blind systems are exclusively available in this standard 28mm thickness to comfortably accommodate the slats. |
| The Glazing Beads | We absolutely must securely remove the plastic or aluminium ‘beads’ holding your current glass in place. In most modern PVCu and aluminium frames, this is easily achievable. However, some older systems were actually built tightly around the glass, making removal highly difficult. |
| The Window Size | Exceptionally small or incredibly narrow ‘slit’ windows simply do not possess enough internal space to successfully house the mechanical blind system and the sliding magnets. |
⚠️ A Warning Regarding Timber Frames
While traditional timber windows and heavy doors also utilise a standard bead-type system, these wooden beads can very easily split or shatter when our engineers attempt to carefully remove them. Retrofitting blinds into timber frames requires a highly delicate touch and sometimes necessitates purchasing entirely new wooden beads.
5. Frequently Asked Questions
