Custom Size Manual Blinds for Roof Lanterns Calculator
Game changer!!

We put a roof lantern in our new extension and thought we might not have thought it through properly! We have been roasting in this hot weather with the sun beating through said skylight. We found Lanterns Direct having decided a skylight blind might help cool us down! Other companies were much more expensive and we didn’t want to have to make an appointment for a visit or submit measurements and wait for a call with a cost. We submitted our order and received confirmation and another email ensuring that we had submitted the correct measurements. The blind arrived in good time and was easy to install. Opening and closing it is easy - though on reflection a remote might be preferable - and we are definitely much cooler! We are delighted with it. Would highly recommend Lanterns-Direct and definitely use them again should the need arise. Well deserved 5 stars.

Excellent blind, very pleased with it!
With the dual blind it goes down very small, and only requires one power source!

Service top

Ondanks dat de zending blijf hangen in een kapotte vrachtauto heeft LD me top geholpen door een 2e af te sturen en een korting te geven. Super service.

Iets te weinig maar dan had ik zelf ook beter moeten uitvragen.

Good skylight blind - I like it

It works as intended. It was easy and quick to install and helps massively to manage the light and temperature situation in the room.
The motor and the mechanics are relatively quiet and easy to operate with the remote.

Everything went very smoothly from ordering to delivery. The window and surround were delivered very safely on a pallet with an upright structure to protect all the parts. It was then very straightforward for my builder and roofer to fit. It is a big improvement on the "old" roof. Many thanks to you all Des Berriman
