Skyseal Laminated Glass Roof Lantern

Roof Lantern Design and Glazing Options

Roof lanterns are glazed structures designed to maximise daylight from every angle, so choose from a 4-pane or 6-pane design depending on the size and shape of your opening. Both styles deliver the same core benefits: more daylight, better ambience and a stronger connection between your indoor and outdoor space. Prefer a different roofline? We also offer this glazing in a pyramid profile, which suits a squarer opening just as well.

Getting the glazing right matters as much as the shape. We can help you balance light levels, thermal performance and solar control so the finished piece suits how you actually use the room, whether that's a bright kitchen extension, a shaded home office or a self-cleaning finish that cuts down on upkeep.

Sizes and Made-to-measure Options

Standard 4-pane sizes are available in 3-5 working days. 6-pane and bespoke sizes take 10-15 working days once production starts. Need something outside our standard range? Our made-to-measure lanterns are built to your exact external measurements, and this exact product is also available as a fully bespoke build if you'd rather start from your own dimensions.

Roof lanterns are cheap to run over the long term thanks to their thermal performance, and roof lantern installation is generally straightforward on single storey extensions once the upstand is ready. An upstand width of at least 85mm is recommended, and our installation guide covers everything you need for installing a roof lantern, from first fix through to final sealing.

Installation and Planning Permission for Roof Lanterns

Fitting a flat roof lantern usually falls under permitted development, particularly for rear extensions and single storey projects. Planning permission can still apply for listed buildings, conservation areas, or larger alterations, so it's worth checking your local authority's building regulations before you order. Our help and advice hub covers this in more detail, alongside sizing, glazing and delivery guidance for every product we sell.

Suited to Any Room

These roof lanterns work well in kitchens, living spaces and flat roof extensions, and suit a bathroom or kitchen flat roof skylight just as well, anywhere extra daylight makes the biggest difference. For a full comparison of shapes and glazing, our guide to roof lantern styles and complete guide for UK homes both cover what suits different extensions and room types.

Maintenance and Cleaning

A self-cleaning glass finish is available if you'd rather cut down on upkeep, particularly useful given how exposed this glazing is to the weather and easier than manually cleaning glass. Read more about how self-cleaning glass works if you're weighing it up against a standard finish.
