Frequently Asked Questions

  • Are skylights noisy when it rains?
    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.
  • Do roof lanterns need planning permission?
    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.
  • Do roof lanterns make the room hot?
    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.
  • Can I schedule my builder or other trades before the materials arrive?
    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.
  • Are opening skylights worth it?
    Opening skylights bring many advantages to your living space, one of the main purposes of an opening skylights is to bring ventilation into the room, enabling you to cool down a hot room on a summer’s day. Unlike fixed skylights, opening skylights give you more control over the temperature of the room. One of the main concerns we see regarding an opening skylight is the question of; what if it rains? If this is a concern to you, we offer a rain sensor at an extra cost, which will automatically detect rainfall and close the opening. Having a rain sensor reduces the risk of any water coming into your home, if accidentally left open there is no need to worry about the consequences.
  • What are the benefits of skylights?
    Skylights increase the light in a room 3 times more than a standard window. A skylight is an eco-friendly lighting solution, designed to save you money on your energy bills. They open living spaces, improve the look of your space, and create the illusion of a bigger room. Not only do skylights bring in natural light, but they also provide an architectural appearance, especially the lantern skylight as they mimic an orangery feel. They are a much more affordable solution to lighting, choosing one of our stock sizes will also keep the costs as affordable as possible.
  • Roof lantern vs flat rooflight?
    The main difference between a roof lantern and a flat rooflight is their appearances. A roof lantern tends to provide an architectural feature to a property, being three-dimensional. They also increase the height of a room, aiding to make the room feel more spacious. A flat rooflight is a great option if you want minimal disruption to the outside look of your property. You can also create a multipane rooflight formation to keep the weight of the rooflight down and prevent the need of lifting equipment. The multipane rooflights are becoming increasingly popular due to their architectural appearance and reducing the need for special lifting equipment.
  • Key features of a roof lantern?
    We offer two types of roof lanterns, a fixed roof lantern, with no ventilation, and an opening Sheervent lantern. The Sheervent opening lantern has an automatic opener, providing extra ventilation, the automatic opener can be operated as standard by a wall mounted switch, or can be upgraded to also include a remote control.

    The roof lanterns come in a variety of sizes. The biggest size for a roof lantern is 4000x 6000mm. However, we can supply a lantern with a length of up to 8000mm if the width is up to 2000mm. Please note that bespoke sizes are more expensive than our stock sizes stated on our website, due to ordering quantities.
  • What size flat rooflight?
    The size of the rooflight you require depends on many factors such as your available roof space and your budget. Please note that our smallest flat rooflight we can offer is 300mm x 300mm and the largest size we can do in one piece is 2000mm x 4000mm. It is worth also considering the installation costs of a larger flat roof light will be greater and you will require specialist equipment.
  • Can skylights open?
    We do supply opening flat rooflights and roof lanterns, our openers are electric only. We do not supply manual openers. Our electric opening skylights can be operated by a wall mounted switch or a remote control. The remote control would be an additional cost for our stock sizes. Other additional features our openers can have include thermostatic controls and a rain sensor.

The opening rooflights have an opening of 300mm, for ventilation purposes only, not access.
  • How to clean a roof lantern?
    The roof lantern comes with self-cleaning glass. Installing your rooflight at the correct pitch will also help to keep the glass clean as it will allow for rainwater to run off the surfaces. The unique dual-action self-cleaning coating is located on the external pane of glass. The coating has revolutionary photo-catalytic and hydrophilic properties, and works in two stages: Stage 1) The coating reacts with natural daylight to break down and loosen organic dirt. Stage 2) When it rains, instead of forming droplets, the water spreads evenly over the surface of the glass, helping to wash away my dirt and reduce streaking. During long dry spells the glass can be cleaned by simply hosing it down with clean water.
