Why Lumizen is the safest choice for your home

✅ 100% walk-on and fall-safe
✅ Complies with building regulations
✅ No additional insurance required

Many suppliers use standard glass only, which can be dangerous. Have you ever considered what happens if someone walks or falls directly onto it? It does not meet the required safety standards (EN 12600) for overhead glazing. At Premium Skylights, we take no risks when it comes to safety. Our walk-on skylights are equipped as standard with laminated safety glass with high load-bearing capacity. The same technology used in car windshields: in case of breakage, the glass remains held together by a strong interlayer.

Premium design, maximum performance

Thanks to the Modern Infinity Design, water and dirt wash away immediately. No raised edges, but a flat glass panel of A-brand quality (Saint-Gobain) for a lasting clear view.

Customize the window completely to your preferences with our different types of glass: choose Clear glass (best seller) or opt for our Artic Snow or Cool White versions when you want maximum light but also privacy.
