The EOS roof lantern is a more cost-effective solution than our Sky-Line roof lantern but is a viable alternative because as well as value for money it boasts comparable design features.

Intelligent engineering during the roofs design means we have been able to surpass the requirements  for structural strength whilst still offering extremely slender aluminium profiles. The spar sightlines throughout the roof are only 57mm wide, and the ridge sections are one of the slimmest currently available on the market.


All Express roof lanterns are designed and structurally guaranteed by our experienced, technical team. The roof itself has been designed around maximum uninterrupted sight lines bar numbers are reduced (or can be added if you prefer) boasting hidden fixings and unbroken sightlines the key design element of the roof is to make all elements as unobtrusive as possible. Minimal profiles and maximum glass are the key fundamentals that drive the popularity of this aluminium roof lantern.
