Frequently Asked Questions

How do the different tints affect light passing through the dome?

Clear tinting will enable from 78% of light (triple skin) to 85% of light (double skin) to pass through and enter the house. Our textured finish provides a high degree of privacy and allows between 72% of light (triple skin) and 78% of light (double skin) to pass through. Our Solar Control bronze finish will allow from 36% of light (triple skin) to 39% of light (double skin) to pass through. And our Diffused Light & Solar Control Opal tint will allow from 32% of light (triple skin) to 35% of light (double skin) to pass through.

Will I need planning permission to install Mardome Reflex Polycarbonate Dome Rooflights?

Typically planning permission only enters the picture if the rooflight you install protrudes noticeably above the established roof line of your home or business. However, since Mardome Reflex Polycarbonate Dome Rooflights sit very low against the roof it is possible you will not need planning permission. But don’t assume anything, ask your local authority. In addition, if your home or business is a listed building or if it’s located in a designated conservation area you will probably need planning permission.

How do I obtain planning permission?

Obtaining planning permission is a pretty straightforward process, although it’s not free. Here’s how it’s done in most cases:

  • Obtain a planning permission form from your local authority.
  • Fill it out and pay the £60 application fee.
  • Submit the application along with your plans for installing the rooflights.
  • If the local authority requests additional documentation, supply it to them without delay.
  • Wait 6 - 8 weeks to hear whether you’ve been approved or not.

Will you install the dome rooflights?

We are not able to offer an installation service at this time. However, each one of the dome rooflights we sell is delivered with comprehensive installation instructions. These should be more than sufficient to guide you or your contractor through every phase of the installation process. If you should lose the instructions that came with the rooflight simply call and we’ll send you a copy.

Do Reflex Polycarbonate Dome Rooflights come with a warranty?

Of course. We sell only the highest quality rooflights and stand behind them with a generous warranty so you don’t have to worry. If you would like to learn more about these polycarbonate rooflights, or you would like more information about our warranty, contact our customer service department on 020 4538 3079. 

Fitting and Measurements

The product data sheet and instructions for installation in PDF form to download can be found at the foot of this page.

Please read the following installation instructions first.

This item has been designed to fit to a kerb. Bespoke fitting can be achieved with the 70mm or 100mm wide fixing undrilled flange which is included.

A builders upstand is required for the Mardome Reflex Dome to be fitted directly. The external dimensions of your upstand (complete with finished roofing material) should match the unit ordered. For example, if your upstand measures 1200mm x 1200mm you should order a unit measuring 1200mm x 1200mm.

There is a small margin for error automatically built into the unit. This enables uneven material on the roofing or minor variations on the kerb to be accommodated. Please see the diagram below for illustration.

Acceptable margin:

70mm flange option = dome size +18/-60mm
100mm flange option = dome size +18/-120mm

If you order a 900 x 900mm from our available selection of sizes, this should be the same size as the external measurements of your upstand width, as illustrated above. The built-in margin means that, for example, if you order the 70mm flange, it will fit any kerb measuring 840mm to 918mm.
