Opening device for rooflight and smoke and heat vent
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 LC circular 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 devices for circular domes can be either manual or electric. Circular domes can have a double-walled base in polyester resin reinforced with fibreglass, with a layer of expanded polyurethane between the two walls. Opening frames are in fibreglass reinforced plastic.
AMLC - Circular manual opening device constituted by frame and counter frame (with C configuration) in polyester resin reinforced with fibreglass, complete with gasket seal located on the supporting edge. The opening mechanism can be supplied with a spring latch opening for human passage or with worm screws. The spring latch element in stainless steel and supporting brackets in galvanised steel can only be mounted internally and are activated by manually accessing the dome. The worm screw (300 mm run) can be actioned using a mobile rod with hook (length 2 - 2.5 - 3 metres), supporting brackets in anodised aluminium.
The circular base monolux LC skylight dome can be made from various materials: compact polycarbonate PC with simple or double layers, 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).
