Monolux skylight domes are made from flat layers of polycarbonate or methacrylate using a thermo-forming process. This process involves heating and pressing the layers using female-male dies. The thermo-forming technique used has been perfected thanks to the use of avant-garde machinery managed by software with stored programmes for the different types of materials and dies used. At the end of the thermo-forming process, the moulds are trimmed inside a 5 axis cutting centre, also managed by specific programmes for each type of mould. Monolux domes are completed in the assembly department where the external surface is combined with the internal surface, making them ready for delivery.
Monolux LR rectangular series skylight domes are made in the standard sizes most commonly used in prefabrication, guaranteeing high resistance against mechanical strain caused by atmospheric agents such as snow and strong wind. Opening mechanisms for rectangular domes can be either manual or electric; they can also be fitted with a fire-proof system activated by smoke and heat sensors. Rectangular domes can be supplied with galvanised sheet metal bases, or pre-painted in white with simple or insulated walls. Opening frames are in aluminium.
The rectangular base monolux skylight dome LR can be made from various materials: compact polycarbonate PC with simple or double walls, extruded methacrylate PMMA with simple or double walls, honeycomb polycarbonate with reinforced multiple walls. Assembled during fabrication, domes are supplied complete with gaskets in espansolene and zinc plated steel screws. In PC and PMMA, the dome can be supplied either transparent (light transmission 92% with direct light - beam of light) or opal (light transmission 50% simple wall, 46% double wall in PC with UV ray protection and 68% simple wall, 67% double wall in PMMA).
