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.

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.

Dunstable homes, and what to check first.
The homes. Dunstable grew where Watling Street crosses the Icknield Way. There are older buildings around the Priory Church and the centre, but most homes are interwar and post-war, below Dunstable Downs.
What that means. Most Dunstable homes are straight replacements, where the decisions are glass, colour and whether to change the opening style. Older properties near the centre need more care.
Check first. Houses from the interwar years sometimes still have steel or timber windows. When they come out, the surrounding brickwork and lintels need checking before the new frames go in.

Buying roof lanterns in Dunstable.
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 Dunstable?
Yes. We cover Dunstable and its LU5 and LU6 postcodes from our Milton Keynes base, and everyone who surveys and fits works for us. Nearby, we also fit roof lanterns in Luton, Toddington and Leighton Buzzard.

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.
