Choosing roof lanterns
Choose the lantern around the room beneath it.
Position and size
Think about the kitchen island, dining table and lighting below. We review the structural opening and upstand details with the roof design.
View position and sizeGlass choice
The glazing affects daylight and solar gain. Tell us how much sun reaches the roof so we can discuss an appropriate glass specification.

Compare the frame colour inside and out. Access, the upstand and the roof finish are checked before the lantern is ordered.

Northampton homes, and what to check first.
The homes. Northampton has long streets of Victorian terraces from its boot and shoe trade, older villas and a Georgian centre, and large estates built from the 1970s when the town expanded as a new town.
What that means. The Victorian terraces often have bays and narrow frontages that suit traditional styles. The 1970s and 1980s estates are usually straight replacements of original or first-generation frames.
Check first. Northampton has several conservation areas, including the Boot and Shoe Quarter. Check the status of an older house before changing the style of its windows.

Buying roof lanterns in Northampton.
Product choices, pricing and what happens before we fit.
Should I choose a roof lantern or a flat rooflight?
A lantern rises above the roof with an angled glazed structure; a flat rooflight has a flatter profile. The room layout, roof opening and appearance you want help determine the choice. We can review both with your drawings.
How do I get a price for roof lanterns?
Send us photographs, approximate sizes and your postcode. We review the specification with you and prepare a quote. You can also book a free consultation to discuss the options at home.
Do you supply and fit in Northampton?
Yes. We cover Northampton and its NN1 to NN5 postcodes from our Milton Keynes base, and everyone who surveys and fits works for us. Nearby, we also fit roof lanterns in Wolverton, Newport Pagnell and Stony Stratford.
What our customers say.
Real reviews from real installations. Every one is public, so you can go and check them yourself.
I had an excellent experience with Fenster Glazing from start to finish. Nick Perry and David managed the initial quote to installation process seamlessly, keeping communication clear, honest, and completely stress-free. When it came to the actual fitting, Zac and Shane did a fantastic job with the installation, working efficiently and leaving everything spotless. The professionalism from the entire team was top-notch, and the final result looks brilliant. I highly recommend them.
