Why does Glasscraft use 3mm and 4mm Planiclear glass in its products? 

The thickness of Planiclear glass—whether 3mm or 4mm—is chosen based on the specific needs of your project, including performance, durability, and application type. Here’s why you might see different thicknesses used:

Performance and Durability

• 3mm Glass is lightweight and offers sufficient strength for standard residential applications where impact resistance and durability requirements are moderate. 

• 4mm Glass is stronger and provides better stability and impact resistance, making it ideal for larger windows, commercial buildings, or applications that need extra resilience.

Thermal and Energy Efficiency

• 4mm Glass can provide slightly better thermal insulation when used in double-glazed or triple glazed units such as Hytherm Ultimate, thanks to improved strength and the ability to accommodate larger air gaps between panes.

Aesthetic and Structural Needs

• 3mm Glass is often selected for smaller windows where a sleek, minimal profile is desired, while 4mm Glass offers greater structural integrity, which is needed for larger glass spans or more demanding architectural designs. 

Acoustic Performance

• 4mm Glass may also contribute to better sound insulation when used in applications requiring noise reduction, such as in commercial buildings or areas subject to high external noise.

Customisation for Specific Applications

• 3mm Glass is often used for standard residential glazing, while 4mm Glass is chosen for premium installations or when enhanced strength, energy efficiency, or acoustic performance is required. 

Conclusion 

Both 3mm and 4mm Planiclear glass are integral to Glasscraft’s Hytherm range of glazing products. The choice of thickness depends on your specific needs, whether it’s for strength, thermal performance, or aesthetic appeal.
