Opening Rooflight For Flat Roof - Manual Vent Mardome, Including FREE Winding Rod
Manually opened with a spindle - FREE of charge winding rod
The Brett Martin Daylight Systems Mardome Manual Ventilation polycarbonate opening rooflight for flat roof is an individual contemporary and stylishly designed low rise profile opening dome skylight supplied with a PVC-u multi-walled kerb which are intended for installation onto the flat roofs of all modern building types (both domestic or commercial) to provide natural daylight and ventilation into the room below.
The manual ventilation rooflight opens up to approximately 300mm by way of concealed hinges and the use of a Winding Rod (supplied free of charge with the rooflight) and can provide rapid ventilation into the property. Opening Rooflights can contribute to room ventilation as required by Part F of the Building Regulations.
The excellent thermal efficiency of the Triple layer Mardome Fixed Polycarbonate Rooflight can achieve a centre pane U-value of 1.8 W/m²K (current Part L Building Regulations require a U-Value of at least 2.2 W/m²K).
For ease of installation, the tapered kerb foot does not require timber fillets and provides a clean external finish for all flat roofing types with a pitch of typically 0 to 15 degrees.
The outer dome of this UK made rooflight is manufactured from 3mm impact resistant Marlon FSX Longlift Polycarbonate sheet which is co-extruded with a UV Protective Coating to both sides for your added comfort. The inner domes are manufactured from 2mm impact resistant Marlon FSX Longlife Polycarbonate sheeting. The upstand which is supplied as standard with this Manual Ventilation Opening Polycarbonate Rooflight is manufactured from Lead and Cadmium free un-plasticised PVC rigid multi-wall extruded profile with an aesthetically pleasing internal gloss white finish. As we are all becoming more environmentally friendly wherever possible, you may be interested to know that the polycarbonate, PVCu and aluminium which comprise the product can all be recycles at the end of the useful product life.
The clever design of the Mardome roof window is such that the actual fixings are concealed within security caps which are supplied with the rooflight. The removal of these security caps to gain access to the fixings themselves is an extremely difficult task thus making this rooflight range very secure to vandalism and intruders. In addition, the rooflights benefit from outstanding resistance to impact, making breakage extremely rare.
The constant separation of the polycarbonate glazing skins across the full width of the dome avoids cold spots and minimises the risk of condensation, especially where the Triple layer option is taken alongside the addition of Trickle Vents.
The contemporary design of the Mardome Manual Ventilation Polycarbonate Skylight range means that they provide a clean appearance and therefore complement the project whether the rooflight is being installed onto the roof of a domestic or commercial property. The low profile domes improve not only the aesthetics of the property but also the clarity of light within the room beneath; harnessing the countless benefits of natural daylight within the premises, alongside the added benefits of natural ventilation.
Mardome Rooflights are designed and manufactured here in the UK under an ISO9001 approved quality system and have full BBA approval and are certified under 06/4385.
The Mardome Rooflights are supplied with a Warranty providing 10 Year Guarantee as standard.
We highly recommend that Trickle Vents are added to the order to help reduce the possibilities of condensation, especially if the Rooflight is to be installed within a kitchen or bathroom area where the possibility of humidity will be higher (please note that Trickle Vents cannot be added to the 450x450mm Rooflight). If Trickle Vents are ordered, they will be installed on the short sides of the PVC-u Kerb (if the rooflight is not square).
The rooflight, as standard, is supplied with 150mm PVCu splayed upstand/kerb for mounting at roof surface level, providing 150mm of waterproofing height (alternative kerb options are available upon request including a tall 300mm PVCu kerb or the Direct Fix (DF) Kerb for installation onto an existing builders upstand on site).
Please note that on rectangular opening rooflights the hinges are positioned on the long side and the rooflight should be installed with hinges facing up-slope. The Rooflight opening mechanism is operated by either a single or tandem worm gears (depending on size), by way of a pole/winding rod which is supplied free of charge with the rooflight.
