Skyseal Laminated Glass Roof Lantern

Contemporary and Classic Appearance

Our Skyseal Roof Lantern can provide you with additional visual interest to key living and dining areas with a choice of a contemporary 4 panel Lantern or a more traditional 6 panel configuration, complementing any style of property. 

Our Contemporary 4 panel roof lantern design minimises the structure to maximise the daylight, while our Classic 6 panel design features additional glazing bars for a more traditional style.

Quick Lead Time

Our Skyseal Roof Lanterns have short lead times to help get your roof lanterns on your roof as soon as possible. Our standard sized 4 pane roof lanterns have a lead time of just 3-5 days, while our standard 6 pane and all bespoke sizes have a lead time of 15-17 days.

Laminated Glass

Our Skyseal products only have glazing units with laminated inner panes for protection from falling glass if accidentally broken.

Not all roof lanterns on the market have laminated glass panes. Instead, they have toughened glass which has an increased risk of injury to those below it if broken.

Engineered For Performance

Slim Aluminium Frame

Our slimline aluminium frames are designed to maximise the amount of light to flow into your space. They were optimised to work in conjunction with the thermally efficient double-glazed units, reducing heat loss and protecting the energy efficiency of your home.

Safety and Protection

Our roof lantern is designed to not only look better but to perform better in terms of lower maintenance and better safety. The precision castings at all junctions provide premium appearance, strength, weathertightness and security

Easy Installation

Expertly designed to minimise the number of parts, maximising the ease of fitting, for efficiency now and throughout the lifetime of the lantern. Precision design removes the need for sealants in installation, apart from the contact of the kerb bar to the builders upstand.

Pre-machined holes and slots throughout maintain the integrity of the components, providing fast, easy assembly.

Questions & Answers (4)

What is Low-e Solar Glass?

Low e-solar glass has a special coating which reflects heat back to the source. This means your room will stay warm in the winter and cool in the summer

Do I really need Triple Glazing?

On Paper Triple Glazed roof lights are the ideal choice for modern homes and can offer u-values as low as 0.6 W/m²K. However, opinion is divided on whether triple glazing has any real thermal impact in the home. Quite often they do very little to reduce your utility bills and the initial costs far outweigh any savings.

What is a Thermal Break?

A thermal break is a layer of low conductive material placed in the Aluminium frame of a skylight. This stop the internal side of the frame becoming cold and in turn eliminates condensation occurring internally on the frame.

What is a U-value?

Thermal transmittance, also known as U-value, is a measure of heat loss through the structure. It is measured in W/m2K. The lower the value, the better the insulation.

The UK Building Regulations require a maximum of 2.2 W/m2K in existing dwellings and an average of 1.2 - 1.7 W/m2K for new dwellings on rooflights.
