When choosing a double glazing company, consider the following factors:

• Reputation: Check online reviews and testimonials from previous customers.
• Certifications: Ensure the company has relevant industry certifications such as FENSA or CERTASS.
• Experience: Look for a company with extensive experience in the glazing industry.
• Warranty: A reputable company will offer a solid warranty on their products and installation services.
• Quality of Materials: Ensure they use high-quality, energy-efficient materials for their glazing solutions.
• Customer Service: Good customer service is essential for addressing any concerns and providing support throughout the project.

A structural glazing system is a method of securing glass to a building structure without the need for traditional framing systems. It uses high-strength silicone sealants or other mechanical fixings to attach the glass directly to the structural elements, creating a sleek, modern, and uninterrupted glass façade. This system is commonly used in high-rise buildings and modern architecture to achieve an elegant and seamless appearance.

• Structural Glazing: In structural glazing, the glass is adhered directly to the structural frame using sealants or other mechanical fixings, resulting in a frameless appearance. It provides a seamless and modern look and is often used in high-rise buildings.
• Curtain Glazing: Curtain glazing, also known as curtain walling, involves the use of a frame to support the glass panels. The frame is attached to the building’s structure, and the glass is then fitted into the frame. Curtain glazing systems can be more versatile in design and are commonly used in commercial buildings and offices.

What is the thickness of glass for structural glazing? The thickness of glass used in structural glazing systems can vary depending on the specific requirements of the project, including the size of the glass panels, wind loads, and safety considerations. Generally, the glass thickness ranges from 6mm to 12mm for single panes. For laminated glass, which provides added safety and security, the total thickness can be 20mm or more, comprising two or more layers of glass with an interlayer.

Good quality double glazing can be identified by several key features:

• Energy Efficiency: Look for a high energy efficiency rating, such as A++ or A+.
• U-Value: The lower the U-value, the better the insulation properties. A good quality double glazing unit will have a low U-value.
• Gas Fill: High-quality double glazing often uses argon or krypton gas between the panes to enhance insulation.
• Spacer Bars: Warm edge spacer bars reduce heat transfer and condensation.
• Seals: Check for robust and durable seals around the glass panes to prevent drafts and leaks.
• Glass Type: Low-emissivity (Low-E) glass improves thermal performance.
• Certification: Look for certifications from recognized bodies such as FENSA, CERTASS, or the British Fenestration Rating Council (BFRC).
