Transforming Rooftops into Year-Round Hospitality Spaces
For city hotels, rooftop restaurants, terrace bars and Sky Lounges, we deliver membrane roof systems that preserve the open-air experience while enabling these valuable spaces to be used throughout more of the year.
At ETNA Membrane Structures, we design, structurally engineer, manufacture and install both fixed and motorized retractable membrane roof systems specifically developed for rooftop and Sky Lounge applications.
We manage the entire project on a turnkey basis — from the initial architectural concept and engineering to manufacturing and final on-site installation.
Making Rooftop Areas Usable Throughout the Seasons
Rooftop terraces are often among the most valuable commercial areas of hotels, restaurants and hospitality developments. However, rain, intense solar exposure and wind can significantly limit their use during certain periods of the year.
With our rooftop membrane systems, we create comfortable protected spaces while preserving the feeling of being outdoors as much as possible.
We develop project-specific solutions for:
Rooftop Restaurants • Rooftop Bars • Sky Lounges • Hotel Terraces • Pool Terraces • Observation Terraces
Our objective is to extend the operational potential of the rooftop without compromising its architectural character or views.
Wind Screen Integration
Wind is one of the most critical design considerations for terraces on high-rise buildings.
Where required, we design side membrane screens and wind protection systems together with the main rooftop structure.
During the engineering phase, we evaluate design wind loads and airflow conditions around the building, developing the membrane, steel structure, connections and anchoring details according to project-specific requirements.
For projects requiring advanced analysis, we perform structural calculations and wind simulations using RFEM and RWIND.
This allows the architectural concept to be developed together with its structural and aerodynamic requirements.
Illuminated Membrane Ceilings
For Sky Lounges and premium rooftop projects, we use membrane surfaces as more than roofing materials.
We transform them into part of the night-time architecture.
By integrating translucent membrane surfaces with architectural lighting, we create elegant and homogeneous illuminated ceilings after sunset.
LED and linear lighting details are coordinated with the supporting structure and membrane geometry to create a distinctive atmosphere for restaurants, bars and lounge environments.
During the day, the system provides protection and architectural lightness.
At night, the roof becomes part of the guest experience.
Motorized & Retractable Rooftop Roof Systems
For rooftop venues that want to preserve a true open-air experience, we design and manufacture motorized retractable membrane roof systems.
During suitable weather conditions, the roof can be opened to allow the terrace to operate as a completely open-air venue.
When protection from rain or intense sunlight is required, the system can be closed so the space can remain operational.
Depending on the project, we design and manufacture:
Motorized Retractable Membrane Roofs • Folding Membrane Systems • Movable Roof Solutions
This transforms the rooftop into a flexible commercial space capable of adapting to changing weather conditions.
Fixed Tensile Membrane Rooftop Roofs
For terraces requiring continuous protection, we deliver fixed tensile membrane roofing systems.
Using lightweight supporting structures and high-performance architectural membranes, we cover large spans while minimizing the number of columns.
Lightweight construction technology offers a particular advantage for rooftop additions to existing buildings, where additional structural loads can be a critical design consideration.
We shape the membrane geometry according to the architecture of the building, ensuring that the new roof does not appear as an afterthought but instead becomes a natural continuation of the building’s architectural identity.
Protection Without Compromising the View
Preserving the view is one of our primary design criteria for Sky Lounge and rooftop projects.
Column locations, membrane high points, steel structures and perimeter details are developed to minimize interference with important sightlines.
For projects overlooking the sea, city skyline, Bosphorus or natural landscapes, we develop lightweight architectural solutions that maintain a strong sense of openness and visual transparency.
Protect the space. Preserve the view.
Turnkey Rooftop Membrane Systems
At ETNA Membrane Structures, we manage the complete process through a single integrated workflow:
Concept Design → 3D Modelling → Form-Finding → Structural Analysis → Wind Analysis → Steel Structure → Membrane Engineering → Manufacturing → Lighting & Movable System Integration → Transportation → Installation → Handover
This provides investors, hotel operators, developers and architectural practices with a complete turnkey rooftop roofing solution from initial design through final installation.
Where We Apply Our Rooftop Systems
We design and install rooftop membrane and retractable roof systems for:
City Hotels • Five-Star Hotels • Rooftop Restaurants • Sky Lounges • Rooftop Bars • Terrace Cafés • Beach Clubs & Resorts • Pool Terraces • Shopping Mall Terraces • Residential Social Areas • Observation Terraces
From small boutique terraces to large-span commercial rooftops, each system is engineered according to the specific architectural, structural and operational requirements of the project.
Turning Your Rooftop into a Revenue-Generating Space for More of the Year
For a rooftop restaurant or Sky Lounge, adverse weather conditions are not simply a comfort issue.
They can mean unusable tables, reduced capacity and lost commercial potential.
At ETNA, we create architectural systems that preserve the open-air experience while providing protection when weather conditions demand it.
We bring together:
Fixed Membrane Roof + Retractable Roof + Wind Protection + Architectural Lighting + Steel Structure + Engineering
within one integrated project.
The result is not simply a covered terrace.
It is a flexible rooftop environment designed to increase usability, enhance the guest experience and maximize the commercial potential of one of the building’s most valuable spaces.
