Lantern Roofs, Skylights
& Glass Canopies

Let light flood into your home with an Acorn Windows lantern roof

With fewer and slimmer bars than other systems, our lanterns roofs, skylights and canopies transform your house. If you’re building a flat roof extension with a lantern, such as a house extension or orangery, you are sure to create a real sense of interior space and light.

It doesn’t matter whether you want to create a dining room, kitchen extension – or even a bedroom or bathroom; Acorn Windows will help you design and build a stylish room space that is perfect in every way.

Whatever style of property you own, we’ll help you enhance it – meaning you’ll be able to create a traditional or modern effect.

Fill Your Room with Light

When extending your home, the amount of natural light flooding into the room is extremely important as bright spaces add much more value than dark spaces.

Thermally Efficient Design

Our sturdy, insulated and thermally efficient design combined with our A-Rated glazing ensures you’ll keep your bills to a minimum.

Long-Lasting Strength

Because it’s been thoroughly wind tested, you’ll be able to depend on your conservatory lantern’s triple layer storm shield protection and reduced bar frequency to resist harsh weather.

A Range of Other Options

Our Ultrasky lantern can be customised by adding a manual or automatic roof vent. This will allow you to control the temperature of your flat roof extension with lantern and filter out warm air that would otherwise convert into condensation.
