Ceralite™ UV Window Film 

High-Transparency Heat & UV Control Film

Reduce Solar Heat Gain. Save Cooling Energy. Preserve Glass Clarity.

The Hidden Energy Problem with Glass Buildings

Modern buildings increasingly rely on glass façades to achieve openness, daylight, and architectural elegance.

But glass is also one of the largest sources of unwanted heat gain.

Through untreated glass, buildings experience:

  • Intense solar heat penetration
  • Rapid indoor temperature rise
  • Higher air-conditioning runtime and peak demand
  • Discomfort near windows and glazed areas
  • UV damage to interiors, furnishings, and merchandise

In many buildings, HVAC systems are consuming energy simply to remove heat that enters directly through the glass.

What Building Owners and Designers Want

As building owners, architects, and operators, you want

  • Lower cooling energy consumption without changing HVAC systems
  • Heat reduction at the building envelope
  • High visual clarity without dark tint or mirror effects
  • Protection against UV fading
  • Solutions suitable for luxury, retail, hospitality, and design-sensitive spaces

They want energy efficiency without compromising aesthetics.

Ceralite™ — A Smarter Glass-Envelope Solution

ceralite logo

Ceralite™ is a premium, high-transparency heat and UV control window film engineered to reduce solar heat gain while preserving near-original glass appearance.

Unlike conventional dark or reflective films, Ceralite™:

  • Rejects heat without blocking daylight
  • Maintains low reflectivity and natural colour
  • Preserves architectural and brand intent

It functions as a passive energy-saving upgrade, acting exactly where heat enters—the glass façade itself .

Benefits & Performance

Ceralite™ delivers:

  • Significant reduction in solar heat gain
  • Lower HVAC energy consumption
  • Improved occupant comfort near windows
  • Near-original glass clarity and low reflectivity
  • ≈99% UV protection
  • Protection of interiors, merchandise, and finishes
  • Fast ROI driven by energy savings
  • Ceralite™ is compatible with major brands such as 3M Prestige 50, V-Kool VK-55, and Solar Gard TrueVue 30, in visible light, UV rejection and Heat/TSER.

How Ceralite™ Works

Ceralite™ improves glass performance through spectral selectivity, not shading.

1. Solar Heat Rejection

Ceralite™ selectively blocks infrared wavelengths responsible for heat, while allowing visible light to pass through.

This significantly reduces heat entering the space without darkening the glass.

2. UV Protection

Ceralite™ rejects approximately 99% of ultraviolet radiation, helping to:

  • Protect occupants
  • Prevent fading of interiors, furnishings, and displays
  • Extend the life of interior assets

3. Optical Clarity & Low Reflectivity

Ceralite™ maintains:

  • High visible light transmission (≈50–55%)
  • Low external reflectivity
  • Accurate colour rendering

Spaces remain bright, open, and visually comfortable—unlike traditional tinted or mirrored films.

Proof That Energy Reduction Is Achieved

Documented installations demonstrate:

  • Indoor temperature reduction of ~3–7 °C
  • HVAC energy reduction of ~10–25%
  • Significant reduction in peak cooling demand

Lower heat gain through glass leads directly to:

  • Shorter compressor runtime
  • Reduced HVAC stress
  • Extended system lifespan .

Proof That Heat Reduction Is Achieved

Measured in installations across Japan:

• Indoor temperature reduced by: 3–7°C
• HVAC energy consumption reduced: 10–25%
• UV light blocked: ≈99%
• Visible light transmission preserved: High clarity / no tint
• ROI (simple payback): 12–30 months, depending on building envelope size & HVAC load

This directly lowers monthly energy bills and extends the lifespan of HVAC compressors, reducing maintenance & replacement capex.

Customers, the Proven Track Records

Ceralite™ is trusted in high-profile, design-sensitive installations, including:

  • DIOR Ginza Six flagship store (Japan)
  • Mercedes-Benz dealerships across Japan (200+ sites)
  • Toyota and Suzuki dealership networks
  • Luxury hotels, resorts, and cultural buildings

Why Glass-Level Heat Control Saves Energy

When less heat enters through windows:

  • Indoor temperatures stabilise faster
  • Air-conditioning cycles less frequently
  • Cooling capacity requirements drop
  • Energy consumption decreases continuously

Ceralite™ delivers recurring operational savings, not just a one-time improvement.
