Windows equipped with 44.2 VSG LE glass provide superior security, durability, and acoustic performance compared to those with 43.2 VSG LE glass. The key reasons for choosing 44.2 over 43.2 are:
Higher Burglary Resistance – The additional millimeter of glass thickness (4 mm + 4 mm vs. 3 mm + 4 mm) significantly improves resistance to break-ins. More time and effort are required to penetrate the glass, making unauthorized entry more difficult.
Greater Mechanical Strength – The symmetrical 4 mm + 4 mm composition in 44.2 ensures better load distribution, reducing the risk of breakage from external impacts (e.g., attempted break-ins, strong winds, or accidental hits).
Improved Sound Insulation – Heavier glass in 44.2 reduces noise penetration better than 43.2, making it a better choice for urban areas, busy streets, or industrial zones.
Compliance with Higher Security Standards – 44.2 is better suited for achieving higher safety classifications (e.g., P3A/P4A burglary resistance according to EN 356), making it ideal for homes, offices, and commercial spaces where security is a priority.
If security and durability are essential, windows with 44.2 VSG LE glass offer a clear advantage over 43.2 VSG LE. The added thickness strengthens resistance to physical attacks and enhances acoustic performance, providing greater protection and comfort for end users.
