Frequently Asked Questions
Expert answers to safety glass questions
Laminated glass has a plastic interlayer that holds glass together when broken, providing security and noise reduction. Toughened glass is heat-treated to be 4-5 times stronger and breaks into small, safe pieces.
Laminated glass provides superior security as it's very difficult to break through - the plastic interlayer holds fragments together. Toughened glass offers impact resistance but can be completely penetrated once broken.
Yes, laminated glass provides excellent noise reduction (30-40dB) due to the acoustic dampening properties of the plastic interlayer. Toughened glass offers minimal noise reduction benefits.
UK Building Regulations require safety glass in critical locations. Toughened glass is typically sufficient for most residential applications, while laminated glass is preferred for security, noise reduction, and commercial use.
Laminated glass typically costs 40-60% more than toughened glass. For Bishop's Stortford homes, expect £80-150 extra per window for laminated vs toughened safety glass.
Yes, you can specify different glass types for inner and outer panes. For example, toughened glass outside for weather resistance and laminated glass inside for security and noise reduction.
