Are the lantern roof lights safe?

A completed installation of the Smarts Aliver Orangery Roof Lantern is completely secure. The design incorporates the use of pressure plates, and these are secured with tamper-proof screws. So you have peace of mind that the roof is safe, strong and secure.

Why do you only offer aluminium?

We believe in only offering the best for our customers. With aluminium roof lanterns, we know that you’re getting a solution that is strong and durable, able to withstand the elements. They’re built to last, so customers have a finished product that is going to age well and stay looking great for many years to come.

The thermally-broken design of the frames makes our aluminium roof lanterns a low maintenance solution that is energy efficient as the roof lights are insulated against heat loss. There is also a reduced risk of condensation. To keep the frames in top condition, they will only require a periodic wipe-down.
