Mardome Trade Fixed Roof Dome

The Mardome Trade Fixed Roof Dome comes complete with a host of features and benefits as standard to satisfy a range of projects and budgets. Available in double and triple polycarbonate with glazing and upstand options, these units are made bespoke to your specification.

The factory assembled Mardome kerb in two waterproofing height options, 150 mm and 300 mm, are available for projects with no existing upstand. Made from white multiwall PVC, the kerb is extremely robust and has been designed to provide maximum insulation, whilst its steep sloped walls allow for a significantly larger glazing unit on top providing more daylight into the area beneath.

Contemporary Design

  • Sleek, contemporary aesthetics inside and out.
  • Aerodynamic low rise glazing unit.

Maximum Daylight

  • Side Walls of the Mardome kerb are designed with a steep slope to allow a larger glazing unit to be fitted for maximum daylight.

Thermally Insulating

  • Multi-wall kerb contributes to the high insulation levels
  • Full insulation across the whole width of the rooflight on triple skin and better glazing variants to minimise risk of condensation.
  • Triple Skin glazing option exceeds the thermal requirements of Part L with a centre pane U-value of 1.8 W/m2k.

Easy to Install

  • Delivered to site complete and ready to fit in robust packaging for easy handling.
  • Mardome kerb foot radius facilitates easy application of roof covering to the termination point without the need for timber fillets.

Robust, Durable and Secure

  • Secure fixings with tamper-proof caps
  • Multi-wall Mardome PVC kerb is robust and resilient to damage during installation
  • Marlon FSX Longlife polycarbonate, with UV protection for weatherability and an impact resistance 200 times greater than glass.
  • Fully CE Marked product.

Glazing Options

All mardome rooflights are glazed with impact resistant Marlon FSX Longlife polycarbonate, which is 200 times stronger but less than half the weight of glass. Featuring dual sided UV protection, Marlon FSX prevents up to 98% of damaging UV radiation from penetrating the sheet, protecting the occupants beneath the rooflight whilst also ensuring long-term weatherability. The outer skin is available in a choice of finishes, Clear, Textured or Opal:

  • Clear - Maximum Light Transmission. Maximum clarity of vision of views and objects through the dome.
  • Textured - Combines Privacy with high levels of light transmission. Diffused daylight. 
  • Opal - Combines Privacy with high levels of diffused light transmission. Prevents solar glare and reduces solar heat gain. Impairs vision of views.
