Planibel A Glass Solutions for Modern Homes & Projects
High-performance low-emissivity glass delivering outstanding thermal insulation and crystal-clear light transmission for windows, doors and architectural glazing.
What Is Planibel A Glass?
Planibel A is a premium float glass product manufactured by AGC Glass Europe, one of the world's largest glass producers. It features a specially engineered pyrolytic low-emissivity (low-e) coating that is applied during the float glass manufacturing process itself — making it an integral part of the glass rather than a surface treatment applied afterwards.
This hard-coat technology gives Planibel A exceptional durability. Unlike soft-coated low-e glasses that require careful handling and must be positioned within sealed units to protect the coating, Planibel A's pyrolytic surface is robust enough to withstand processing, handling and even exposure to the elements without degradation.
The result is a glass product that delivers measurably better thermal insulation than standard float glass, while maintaining the high visible light transmission and neutral appearance that homeowners expect. When used in double-glazed or triple-glazed sealed units, Planibel A significantly improves the overall U-value of the glazing assembly.
At 313 Glass, we specify Planibel A glass across our product range where enhanced thermal performance is a priority. It is available in all our window, door and bespoke glazing products.
Key Benefits of Planibel A Glass
Why specifiers, architects and homeowners choose Planibel A for superior glazing performance.
Enhanced Thermal Insulation
The pyrolytic low-emissivity coating on Planibel A glass reflects long-wave infrared radiation back into the room, significantly reducing heat loss through the glazing. This improves the overall U-value of the sealed unit and contributes to lower heating costs throughout the year.
Excellent Light Transmission
Unlike some coated glasses that produce a noticeable tint, Planibel A maintains high visible light transmission. Rooms remain bright and naturally lit, with no perceptible colour shift or reduction in clarity — the glass looks virtually identical to uncoated float glass.
Neutral Appearance
Planibel A's pyrolytic coating is applied during the float glass manufacturing process, resulting in an extremely thin, durable layer that does not alter the visual appearance of the glass. There is no reflective sheen or coloured tint.
Exceptional Durability
Because the coating is pyrolytic (hard-coated) rather than sputtered (soft-coated), it is extremely robust and resistant to scratching, handling damage and environmental degradation. This makes it easier to process and longer-lasting than soft-coated alternatives.
Versatile Application
Planibel A can be used in double-glazed and triple-glazed sealed units, and is compatible with a wide range of frame systems including uPVC, aluminium and timber. It works in windows, doors, bi-folds, fixed glazing and rooflights.
Energy Bill Savings
By reducing the amount of heat that escapes through your glazing, Planibel A glass directly contributes to lower energy consumption. Over the lifespan of a window or door, the energy savings can be substantial.
Where Planibel A Glass Is Used
Planibel A is a versatile product suitable for a wide range of residential and commercial glazing applications:
- Replacement windows in residential properties
- New-build window and door glazing
- Bi-folding door sealed units
- Composite and uPVC door glazing panels
- Fixed architectural glazing features
- Conservatory and orangery roof and side glazing
- Rooflight and skylight applications
- Commercial glazing projects requiring thermal compliance
Technical Performance
Planibel A's pyrolytic coating modifies the emissivity of the glass surface, reducing radiant heat transfer. Key performance characteristics include:
