Our most frequently asked questions regarding aluminium and PVCu roof lanterns, skylights, and orangeries all in one handy place. If there's anything you still need to know, give our friendly team a call.

What is a u-value?

The U-value of a product measures how effective its insulation properties are. The lower the U-value, the better the insulation. As a guide, a standard double-glazed window typically has a U-value of 2.8 W/m². Our super insulating units achieve a U-value of 1 W/m².

Will it be noisy if it rains?

Sound insulation is important when choosing your roof lantern. There are four main factors that can limit rain noise: The number of panes of glass — noise levels are reduced with each additional pane The distance between the panes — the greater this distance, the better your sound insulation will be The thickness of each pane of glass — thicker panes absorb more noise How well your lantern is sealed against the roof. Further insulation in the skylight’s structure help keeps rain noise to a minimum.

What is the largest aluminium roof lantern you make?

Our aluminium roof lanterns can go up to 3000mm in width and a length up to 6000mm. We can also produce the PVCu Skypod skylight up to a length of 8000mm. Please note, larger roof lanterns do require the introduction of additional glazing bars.

How long until my roof lantern is delivered?

Aluminium roof lanterns and PVCu skylights are usually delivered to your site within 7 - 10 working days, however this can sometimes be longer depending on manufacturing load and delivery schedules. Please be advised that glass may occasionally arrive a day or two after the frame.

What is a thermal break?

A thermal break is a material with low thermal conductivity that is placed between two different conductive materials. Its job is to reduce or prevent the flow of thermal energy. In our products, these thermal breaks include resin, silicone and styrofoam, which separate the conductive aluminium components to provide superb thermal insulation.

What pitch should my lantern be?

We offer aluminium and PVCu roof lanterns in pitches of 20º and 35º.
