Fixed Roof Window for Pitched Roof
Why Lumizen is the safest choice for your home
✅ 100% Fall-through safe
✅ Complies with building regulations
✅ No additional insurance required
Many suppliers offer only standard glass, which can be dangerous. Have you ever thought about what happens if someone 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 roof windows are standard equipped with laminated safety glass. This is the same technology used in car windshields: in case of breakage, the glass remains attached to the foil.
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), heat-reflective Solar glass to keep the temperature comfortable on sunny days, or go for our Arctic Snow or Cool White versions when you want maximum light but also privacy.
Ultimate Living Comfort: Quiet, Warm & UV Protective
The combination of HR++ insulation, double Low-E coating and Warm Edge technology ensures a lasting insulation value of 0.78 W/m²K, reduces outside noise and blocks 100% of harmful UV radiation. This keeps your home quiet, comfortable and prevents interior discoloration.
Lumizen: Direct from the factory
Lumizen is our own brand, developed through years of hands-on experience. Because we design and deliver directly, we guarantee 100% quality control and an excellent price-quality ratio.

Quick help and service even with damage they had nothing to do with
Super service and a beautiful product.
I was surprised by the friendly service. The window was delivered well and was easy to install. It looks beautiful.
Even more beautiful than expected!
We needed it for a client of ours and it had to be mounted above a sliding door, the result is beautiful.
After having telephone contact, ordered a skylight with upstand from Premium Skylights!! Neatly delivered with their own transport
Great, would not have expected anything else. Although I don't think doorstep delivery was right, you should be able to manage the transport yourself.
Ordered 3 large skylights of which one (the largest) from Premium Skylights. In terms of quality, this is the best of the three.
Correct and fast delivery and good information about the installation.
Fast delivery and neatly placed in the garden
The skylight was delivered quickly and the driver helped us out. The panel was well packed in a wooden frame, making the skylight easier to lift. Due to the weight of 105 kilos, it is advisable to place the skylight with three or four people.
Beautiful quality skylights. Ordered with upstand, much easier that way.
Easy to install with clear instructions.
Good service.
Good price-quality ratio
We couldn't quite figure out the assembly ourselves but after contact everything was resolved. Good communication.
The skylight was delivered well and securely packed. Installation went fairly easily with the supplied instructions. The result looks beautiful. Very happy with the purchase.
