Roof Hatch - Mardome Rooflight Access Hatch - Brett Martin

Mardome Trade Access Hatches are individual contemporary and stylishly designed low rise profile polycarbonate dome skylight Roof Access Hatches with a PVC-u multi-walled kerb which is intended for installation onto the flat roofs of all modern building types (both domestic and commercial) to help the occupants to benefit from the countless advantages of natural daylight within the room below alongside providing safe, easy access to roof spaces for roof maintenance thus negating the need for cumbersome and costly scaffolding.

The excellent thermal efficiency of the Triple layer Mardome Roof Access Hatch means that it can achieve a centre pane U-value of 1.8 W/m²K (please note that current Part L Building Regulations require a U-Value of at least 2.2 W/m²K).

For ease of installation, the tapered kerb foot can be installed directly onto the roof-deck to provide a clean, modern extremal finish for all flat roofing types which have a pitch of typically 0 to 15 degrees.

Mardome Trade Access Hatch rooflights feature internal opening mechanisms incorporating hinged dome unit and gas springs to facilitate an opening angle between 70° and 83°, depending on the dimensions of the flat roof window access hatch.  Units come complete and ready to fit.

The Roof Access Hatch incorporates robust hinges and opens with the assistance of Gas Struts and incorporates one or two lockable handles, depending on size.  When in the open position, the dome unit is fully supported by the gas struts thus reducing the possibility of injury when in operation. 

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 150mm high upstand which is supplied as standard with this Roof Access Hatch 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 increasingly environmentally friendly, wherever possible, you may be interested to know that the polycarbonate, PVCu and aluminium which comprise within the product can all be recycled at the end of the useful product life of this rooflight.

The clever design of the Mardome roof access hatch is such that the actual fixings/fittings are concealed within security caps which are supplied with the rooflight.  The removal of these particular 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 roof access hatches 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 the possibility of 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 Polycarbonate Rooflight range means that they provide a clean appearance and therefore complement whatever the project may be; 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 itself but also the clarity of light within the room beneath; harnessing the countless benefits of natural daylight within the premises.

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 Roof Access Hatch range are supplied with a Warranty providing 10 Year Guarantee

We highly recommend that Trickle Vents are added to the order to help reduce the possibility of condensation (please note that single Trickle Vents will be installed on Access Hatches with a length of 1200mm and less).  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 roof access hatch, 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 builder’s upstand on site).
