Roof lanterns are a beautiful idea for adding further natural light into an extension or even an existing area of your home. Not only do they improve the lighting in any interior space, but they also add an architectural element and a guaranteed ‘wow’ factor to your home. 

Roof lanterns strike a beautiful balance between classic and modern, and can be added to a period property without affecting the overall aesthetic. 

What are roof lanterns?

Roof lanterns are best described as a hole in the roof topped with glass panes in a prismatic shape. They are double glazed, so they don’t compromise your insulation or weatherproofing, but you should always opt for a reliable, trusted contractor who can show you plenty of their previous projects to install them. 

Why choose aluminium roof lanterns?

Many people opt for aluminium profiles over UPVC, because the aluminium bars and the overall structure of the roof lantern is slimmer. Aluminium can be made slimmer because it’s a strong yet lightweight material choice that offers more sky, less roof.

Aluminium roof lanterns are also available in over 150 RAL colours so that you’re able to match it to your existing windows or to a particular colour scheme in your home. The colour finish with aluminium is usually powder coated, which is incredibly durable and offers a long lifespan. 

On the flip side of this, however, aluminium tends to be more expensive than UPVC, which means it may be better suited to those with a more substantial budget. Aluminium roof lanterns work well in both domestic and commercial spaces, but they are incredibly popular for those looking to make improvements to their homes and enjoy things like solar heating or stargazing from the comfort of their interior space.

What are the advantages of UPVC roof lanterns?

UPVC roof lanterns are a good option for those with smaller budgets but are unfortunately more likely to warp or discolour in the sun. They have a shorter lifespan than their aluminium counterparts, although they do still offer a high-grade product that can be perfectly matched to your existing windows and doors, as they’re also available in 150 RAL colours.

Ultimately, when it comes to choosing between aluminium or UPVC, it will likely be down to your budget. Aluminium is the superior material, with better strength and durability without the thick bar profiles.
