Modular Rooflights Alumasc A Range Alumasc A Range Superior Modular Rooflights Alumasc A Range are superior modular dome rooflights providing high levels of security and waterproofing. The lock-bolt security system means installation of the rooflight is straightforward, precise and secure. Removal of the glazing can only be achieved with the use of a lock-bolt security opening device. Key Benefits Maximum security dome rooflight Smooth clean appearance Lock-bolt security system Complete waterproof integrity with the roofing membrane High performance insulated kerb New kerb for fast efficient installation Unique to the flat roofing market, the Alumasc kerb is designed to allow roof coverings to be terminated horizontally at the upper edge of the kerb wall. This practice improves the weathering detail of the rooflight.

The PVC-U frame also conceals all the fixings of the unit, acting as a deterrent to the opportunistic intruder. Alumasc A Range will not compromise the waterproofing of the roof because the kerb has been designed to allow the roof covering to terminate horizontally on the upper edge of the kerb wall. The waterproofing membrane is clamped into place by the lock-bolt security system once the glazing is attached to the kerb. The attractive design of Alumasc A Range rooflights integrates well with any flat roof membrane system. The white internal finish of the kerb means the rooflight blends with any interior décor. Alumasc A Range rooflights are available in a curved dome or pyramid profile and in a wide range of sizes. A full range of ventilation options is also available. Alumasc A Range is particularly suited to applications such as schools, hospitals, sports and leisure centres, offices and other buildings where security is of particular concern.

Modular Rooflights Alumasc A Range Tall kerb simplifies installation A kerb height of 5mm allows the designer to determine the most appropriate way of fixing the rooflight to the roof structure. Kerb options Where a non-standard roof opening exists, kerb adaptors can be specified to provide an exact fit into the prepared builder s upstand. Insulation The combination of a cellular PVC kerb with matching standard glazing guarantees optimum insulation. 8 7 5 6 Designed for security High security is achieved through the unique lock-bolt security system fixing the glazing to the base. This security-lock mechanism can only be opened using a lock-bolt opening device. Curved dome Pyramid dome 5 Simple fixing The lock-bolt security system facilitates fast efficient installation. A series of latches, on the underside of the glazing unit, lock into the kerb, instantly giving a secure watertight fit. 6 Horizontal membrane termination The roofing membrane, when brought over the top edge of the kerb, is secured by the lock-bolt security system, making water ingress virtually impossible. 7 Superb impact resistance The polycarbonate glazing has an impact resistance almost 00 times that of glass, creating a very safe rooflight option. It has co-extruded UV protection and eliminates 98% of harmful radiation. 8 Smooth appearance The PVC-U frame with aluminium reinforcement conceals all fixings creating a smooth, clean appearance.
