The Mardome Trade Is very easy to install. First the kerb is screwed down to the deck using suitable fixings. Once the kerb has been weathered you can continue to attach the dome using the provided self-sealing screws. A full installation guide can be downloaded under the technical data tab

Do Mardome Trade roof lights comply with building regulations?

Mardome Trade roof lights are available in Single, Double and Triple skin. To comply with Part L Building regulation, a triple skin dome must be used.

Will a Polycarbonate Dome roof light make my room cold?

Polycarbonate Dome roof lights are available in Single, Double and Triple skin. To reduce heat loss, we recommend that a triple skin dome be used. This has a U-value of 1.8 W/m2K and complies to building regulations.

Are Mardome Trade roof lights available in bespoke sizes?

Mardome Trade roof lights are only available in set sizes. If you require something a bit more tailored, we recommend upgrading to an Atlas Bespoke Flat Glass Skylight.

What is the difference between single, double and triple skin?

Single, Double and Triple skin refers to the number of layers used when forming a dome skylight. A triple skin dome will comply to building regs and because it has a higher U-value, it will keep your home warmer.

U-values for each are listed below:

  • Single    - 5.5 W/m2K

  • Double   - 2.7 W/m2K

  • Triple     - 1.8 W/m2K

Do I need Trickle Vents for my roof light?

Vents are an excellent way to reduce condensation occurring on the inside of your dome. For high moisture areas, such as bathrooms and kitchens, we highly recommend the addition of Trickle vents.

What opening options are available with Mardome Trade roof lights?

Manual Opening, Powered Opening, Access Hatch and Smoke Vents are available in the Mardome Trade range. Please see our full product range if you are interested in any of these options.
