Product details

Mardome Reflex, single skin — glazing-only replacement dome for existing upstands

One 3mm Marlon FSX polycarbonate skin, co-extruded with UV protection to both faces. The highest light transmission in the Reflex range at 90% clear, and the lowest cost per opening.
This is the dome for daylight where thermal performance is not being assessed — unheated stores, plant rooms, covered walkways, garages, and like-for-like replacement of a cracked or crazed dome on a building where nothing else is changing. It fits the upstand that is already there, so there is no roof opening work and no making good.

  • Ideal for refurbishment projects, suitable for roof pitches up to 15°
  • Achieves Class B non-fragility to ACR[M]001
  • Single skin, double and triple skin units available (separate product listings)
  • Can be mechanically fixed to existing kerbs without a kerb adaptor
  • Choice of colours to suit all light transmission requirements
  • 70mm or 100mm wide flange (undrilled so you can put fixings exactly where needed)
  • Supplied with fixing pack inc. a roll of adhesive, weathertight washers, fixings and caps

How to select the correct size roof light

Measure the outside edge to the outside edge of the upstand, any given size of the Reflex dome will fit up to 18mm bigger than the nominal dome size or:

60mm less for domes with a 70mm flange

120mm less for domes with a 100mm flange (100mm flange not available on some sizes)
