AOV Access Roof Hatch. Our rooflights are manufactured from solid polycarbonate sheets with proprietary UV protection on both sides offering excellent weathering properties and light transmission. Polycarbonate offers a long service life, high impact resistance as well as a variety of glazing options such as clear, diffused, opal and bronze. Access Hatch An opening hatch that utilises two gas rams to assist opening, mounted internally to a 40mm high UPVC lifting frame which is fitted with galvanised steel reinforcement bars. The hatch will open to between 80-90 degrees to give ease of access to roof level. The Access Hatch is available with Brighton Catch, Hasp and Staple or key operated locking mechanism. Our polycarbonate rooflights are all manufactured using a thermoforming process which has close similarities with vacuum forming except that greater use is made of air pressure. Each skin of the rooflight is manufactured individually and then combined to make the required rooflight. Each adjacent pair of skins are separated by a 20mm air gap to achieve the best possible thermal efficiency. All rooflights are manufactured in accordance with harmonised European Standard BS EN 1873:2005 and carry the CE mark. Our range has been tested for fragility by BRE and attains a class B non-fragile assembly classification. Our polycarbonate rooflights can comply with L1 and L2 of the Building Regulations. All the materials used in the construction of our rooflights and kerbs can be fully recycled. The MK2 Advance kerb offers a ribbed section to the upper section of the external wall to give improved adhesion to a variety of waterproofing systems, it is manufactured using a state of the art CNC manufacturing process, which guarantees accuracy and consistency of each unit produced. This kerb can be used with a Double, Triple or Quadruple skin polycarbonate rooflight. It can also be supplied with a factory fitted, argon filled double glazed glass rooflight to further improve U-values. Designed to be installed at the finished roof level it is therefore the ideal choice for retro fitting to an existing flat roof. The range offers a variety of different options. You can choose from Unvented, Hit and Miss Ventilation, Wormgear opening for maximum ventilation and Access Hatch units should roof level access be required. The MK2 Advance kerb is 168mm high.

Hit and Miss Trickle Vents Offer manually operated ventilation via a sliding mechanism mounted internally to the kerb. The vents are opened and closed as required by hand or by pole.
