Roof lanterns are one of the most striking ways to bring daylight into a home. Their raised glass crown lifts the ceiling and lights a room from several angles. Many homeowners now buy lantern skylight online, yet choosing one involves far more than picking a shape.
This guide shows you how to buy lantern skylight online. You will learn about size, specification and glazing, plus how to compare roof lanterns from different suppliers. Treat it as your rooflight buying guide before you place an order.
Why More Homeowners Buy Lantern Skylight Online
Many buyers now buy lantern skylight online because it saves time and shows the full picture. You can compare styles, read reviews and check specifications from your sofa, rather than waiting for a showroom visit or a quote. Stock is often held centrally too, so delivery can take only a few days.
The catch is that you cannot see the unit in person. That makes accurate measurements, written specifications and a trustworthy supplier essential. The sections below cover each one in turn.
Lantern Skylight Sizes: Getting the Fit Right
Wrong measurements are the most common reason for costly returns. Lantern skylight sizes depend on the opening, the room and the roof structure, so start with the structure.
Measuring the Opening
Measure the structural opening, not the finished ceiling. Allow for the kerb, and check the opening at several points in case it is not square. Write the numbers down and check them twice.
Choosing the Right Proportions
A lantern that is too small leaves the room dim, while an oversized one can cause glare and heat. A common starting point is glazing equal to roughly 10 to 20 per cent of the floor area. Tall rooms can carry a higher pitch, while low ceilings suit a flatter profile.
If your opening is awkward, custom sizes can be made to fit exactly.
Roof Lantern Specifications to Check
Clear roof lantern specifications separate a quality unit from a risky bargain. Ask the supplier to confirm each of these in writing:
- U-value: A lower figure means better insulation.
- Frame material: Thermally broken aluminium is strong, slim and long-lasting.
- Glass build-up: Check the outer pane, inner pane and any coatings.
- Pitch and kerb height: These affect drainage and the overall look.
- Weight and load: Heavy lanterns may need extra structural support.
- Certification and warranty: Ask for proof of testing and a clear guarantee.
Skylights Roof Lanterns, for example, makes its lanterns in the UK, with BBA certification and a 10-year warranty.
Lantern Glazing Options Explained
Good glazing keeps a room comfortable all year. These are the main lantern glazing options.
Double or Triple Glazing
Triple glazing costs more but cuts heat loss and noise. Double glazing suits milder or budget-led projects. Both must meet current Building Regulations.
Coatings and Safety
Low-emissivity coatings hold heat in, while solar control coatings limit summer warmth. Laminated inner panes add safety, because the glass sits above your head. Self-cleaning glass reduces upkeep on high units.
Opening Vents
Some lanterns include vents that release warm, humid air from the highest point. Our opening units offer manual or electric operation.
Skylight Designs and Styles
Skylight designs vary widely, so match the shape to the room. This table compares the most common lantern styles.
| Style | Best For | Key Point |
|---|---|---|
| Pyramid | Square rooms, kitchens | Bold, symmetrical look |
| Rectangular | Long extensions, dining areas | Spreads light along the room |
| Octagonal | Large, open-plan spaces | Soft, wide light spread |
| Minimal frame | Contemporary homes | Slim sightlines, clean finish |
Frame colour matters too. Slim dark frames suit contemporary homes, while white or cream blends with traditional ones.
