Annealed Glass Units

Annealed glass is a standard, high-quality glass option widely used in sealed units for its clarity, versatility, and cost-effectiveness. Ideal for a range of residential and commercial applications, it provides a clean, polished finish while maintaining reliable performance.

What is Annealed Glass?

Annealed glass is a type of float glass that has been slowly cooled during manufacture to relieve internal stresses. This process creates a smooth, distortion-free surface, making it perfect for general glazing applications.
Key Benefits
Clear Finish – clarity for a clean, modern appearance
Cost-Effective – A budget-friendly option for standard glazing
Versatile – Suitable for a wide range of uses and environments
Easy to Process – Can be cut, shaped, or further treated if required

Applications

Annealed glass units are commonly used in:
Standard double-glazed window units
Internal glazing and partitions
Low-risk areas where safety glass is not required
Commercial and residential properties

Important Information

Annealed glass is not a safety glass and, if broken, can shatter into sharp fragments. For areas requiring increased safety or compliance with building regulations (such as doors, low-level glazing, or bathrooms), toughened or laminated glass is recommended.

Annealed Glass Units – FAQs

Q:What is annealed glass?
A:Annealed glass is standard float glass that has been slowly cooled during manufacture to reduce internal stress, making it stable and easy to process.
Q: Where is annealed glass typically used?
A: Annealed glass is commonly used in standard window units, internal glazing, and areas where safety glass is not required.
Q: Is annealed glass safe?
A: Annealed glass is not classed as safety glass. When broken, it can shatter into larger, sharp pieces, which is why it is not used in doors or high-risk areas.
Q: Can annealed glass be used in double glazed units?
A:Yes, annealed glass is often used within double glazed units where building regulations do not require toughened or laminated glass.
Q:What is the difference between annealed and toughened glass?
A: Annealed glass is standard glass, while toughened glass is heat-treated for extra strength and safety. Toughened glass breaks into small, blunt pieces, making it safer for certain applications.
Q: Is annealed glass cheaper than toughened glass?
A;Yes, annealed glass is generally more cost-effective, making it a popular choice for low-risk areas.
