Question 1

Are skylights noisy when it rains?

Accepted Answer

You will be able to hear the rain fall onto a skylight; however, they are not as noisy as you
might think. For some – they enjoy the round of rain as a therapeutic sound. There are a
number of factors that affect the sound insulation: the number of panes of glass, the
thickness of glass, the glazing.
Our flat rooflights have 6mm toughened double glazed glass, the thickness of the glass
contributes to a reduction in noise pollution, our lanterns have 4mm double glazed glass,
however as they have more panes of glass (between 4 – 18) noise levels are reduced with
each additional pane.
All our Titan rooflights have a 20mm argon gas filled spacer with warm edge – this reduces
the heat and noise transmission further.

Question 2

Do roof lanterns need planning permission?

Accepted Answer

Typically, you will not need planning permission for a roof light if it does not exceed a height
of 150mm from the existing roof plane or higher than the highest part of the roof.
However, there are some circumstances where you would need to acquire planning
permission. You can look on the Planning Portal for further information and guidance on
whether planning permission applies to your build. Alternatively check with your local
authority.

Question 3

Do roof lanterns make the room hot?

Accepted Answer

Roof lanterns have insulating properties, they do not generate heat, but they do keep the
heat in. If you are concerned about the heat ventilation, we supply opening rooflights, these
have an electric opening which will increase the ventilation in the room.
Our blue active glass benefits from solar reflective glass externally and heat-soaked
toughened glass internally. Solar reflective glass manages heat by reducing solar heat
entering the building, enhancing comfort, and reducing the need for cooling the building.

Question 4

Can I schedule my builder or other trades before the materials arrive?

Accepted Answer

We strongly advise against scheduling any trades until your materials are on-site. Delays in deliveries may occur, and we cannot compensate you, your builder, or any other trades for any inconvenience caused by delayed deliveries.
