This sail shaped tower allows safe seafront living in Cyprus

The ONE Tower commands the skyline of Limassol. Sitting on the palm tree lined seafront close to both the city’s bustling business district and its quaint old town, the new development offers 83 luxurious residences, leisure, and commercial opportunities set across 37 floors.

The award-winning curved design of the ONE tower is reminiscent of a yacht’s sail, standing at 170m high which, coupled with its coastal location, presented a unique set of passive fire requirements for its facade. 

Design and specification

The height of the tower meant it was vital to ensure the facade construction contained adequate passive fire protection, complying with local regulations and ensuring ongoing safety throughout the building’s lifetime. After years of experience working with Siderise products and its Cypriot distribution partner, DPS, façade contractors, Glassline, specified a combination of Siderise products.

The RH Horizontal Cavity Barriers are designed to allow the facade system to maintain airflow and drain away any moisture within its construction but, in the event of a fire, rapidly close the ventilation gap to create an effective hot smoke and fire seal.

The barriers are complemented with the use of OSCI Cassette Inserts which are Class A2 rated. All these products have undergone rigorous third-party testing to ensure dependable performance.  

In addition to providing straightforward passive fire protection, the stonewall Lamella core of the RV Vertical Cavity Barriers allows them to accommodate the natural movement associated with rainscreen facades. This is especially important on this exposed seafront project. It is also for this reason that the cavity barrier brackets were specified in robust galvanised steel, protecting them from corrosion caused by the sea air.  

Installation and inspection

All Siderise products are designed to be easily installed— a key benefit on this large-scale project, enabling it to be finished to a high standard without compromising the project timeline. The RV Vertical Cavity Barriers and then the RH Horizontal Cavity Barriers were cut to the correct size and installed by Glassline using Galvanised Brackets. Where the two products met, they were simply tightly abutted and the joints sealed with Foil Tape to ensure continuity of intumescence and therefore fire protection.

The OSCI cassette inserts were then fitted as part of the cladding system, installed directly behind the cassette panels and in parallel and centrally aligned to the RV and RH Cavity Barriers. This helped to simplify detailing and ensure the ventilation gap met the project requirements.

Technical support and site services were provided by DPS throughout the design and installation process, in keeping with the Siderise ethos of standing by the side of its customers to deliver optimum results.


Created in collaboration with a number of renowned international and local firms and suppliers, ONE Limassol Tower not only stands as a symbol of the city’s exciting future, but also of what can be achieved when diverse skills, expertise, and vision are brought together. The selection of tested Siderise products chosen for the project will help to ensure that the building remains a safe and beautiful home and landmark for the people of Limassol for many years to come.
