About us

Design and engineering for more liveable spaces

Tensiona was founded with a clear purpose: to transform outdoor areas into more liveable, comfortable and safe spaces in response to rising global temperatures. We specialise in designing, manufacturing and installing tensile shade systems using high-density micro-perforated HDPE sails and lightweight steel, timber or aluminium structures. We do more than create shade; we develop efficient architectural solutions and climate shelters that bring public and private spaces back to life.

We design and develop bespoke solutions, from concept and engineering through to manufacture, coordination and installation. Every structure is created to meet the specific needs of its setting, balancing function, design, strength and sustainability.

We believe there are no limits when engineering and design work together. That is why we create solutions capable of transforming spaces, improving thermal comfort and making environments more liveable.

We turn spaces into more comfortable places

We transform outdoor spaces into places that provide protection, wellbeing and thermal comfort.

Rising temperatures are changing the way we use outdoor spaces. In response to this new climate reality, we design and develop climate shelters that transform outdoor areas into places offering protection, wellbeing and thermal comfort.

By combining lightweight structures with textile architecture, we create visually distinctive spaces.

We create bespoke, durable and sustainable solutions that blend into every kind of setting: squares, parks, schools, sports facilities, hotels, restaurants, commercial spaces and homes.

We manage the entire process: assessment, design, engineering, manufacture, installation and maintenance, delivering an integrated solution from the first idea through to commissioning.

Solutions for every space and setting

Whatever the scale of the project or type of infrastructure, extreme heat and solar radiation demand efficient, durable and visually impeccable solutions. By combining lightweight engineering —calculated steel, aluminium or timber structures— with advanced micro-perforated HDPE sail technology, we design solar protection systems for any setting. From high-performance public-realm projects to leisure areas, educational sites, temporary events and premium private properties, we turn outdoor spaces into ventilated, safe and functional havens of thermal comfort all year round. Discover how we adapt each sector:

Public Spaces and Urban Areas

Climate Shelters and Urban Comfort

We transform squares, pedestrian streets and seafront promenades into liveable places during the hottest months. We design and install tensile systems that act as efficient climate shelters. Thanks to the properties of micro-perforated HDPE fabric, we noticeably reduce perceived heat in public areas without overwhelming the urban environment, providing durable solar-control solutions with minimal visual impact.

Schools and Educational Centres

Protected School Playgrounds and Children’s Areas

We enable pupils to play and learn outdoors safely. We design high-density HDPE sail canopies that block up to 95% of UV radiation. Our lightweight steel, timber or aluminium structures avoid the risks associated with conventional awnings on windy days, creating cool, ventilated shade in school yards, play areas and entrances.

Playgrounds and Leisure Areas

Solar Protection for Parks and Recreation Areas

We extend the hours in which playgrounds can be used, protecting families and the equipment itself. Extreme sun damages play equipment and heats surfaces —slides and swings— until they become unusable. Our bespoke tensile sails provide wind- and wear-resistant cover, turning parks into cool, comfortable and safe places to play.

Corporate, Leisure and Event Projects

Bespoke solutions for businesses, leisure, events and private clients

We design and install shade systems for any infrastructure or outdoor event. We cover large facilities such as water parks, zoos and sports venues, as well as providing comfort and solar protection for events, fairs and local festivities. We also optimise corporate areas, hospitality terraces and private homes with lightweight structures that enhance their surroundings, drastically reduce heat and deliver a contemporary aesthetic.

Technology and materials

Materials engineering for advanced solar control

We combine market-leading textile technology with high-strength structures to ensure durability, contemporary design and outstanding thermal comfort.

Technical fabric

The key benefits of HDPE fabric

Micro-perforated high-density polyethylene offers thermal, structural and environmental advantages over standard PVC tarpaulins and conventional awnings.

Chimney effect

The micro-perforated fabric allows accumulated hot air to rise and escape naturally through the sail. This lowers the temperature beneath the shade in a way that closed plastic covers cannot achieve.

Certified UV protection

It filters and blocks up to 95% of ultraviolet solar radiation, creating safer outdoor spaces for schoolchildren and people using public areas.

Dynamic wind resistance

The micro-perforations let wind pass through in a controlled way. This drastically reduces drag and the “sail effect”, so the entire system bears far less stress during severe weather.

Durability with no maintenance

Premium HDPE does not rot, develop mould or fade after years in the sun, and it is fully recyclable. It is an investment designed for long-term use.

Support structures

Versatility and strength for every setting

We select the right support structure to blend into urban, commercial or natural environments.

Carbon or galvanised steel

Maximum strength for urban settings

Carefully calculated to withstand high tensile loads. Its resilience to vandalism and ageing makes it ideal for climate shelters in public squares, streets and school yards.

Structural aluminium

Lightweight and contemporary

It provides clean, slender lines and a minimalist finish. Its complete resistance to marine corrosion makes it perfect for commercial terraces, hospitality and premium residential projects.

Engineered or treated timber

Landscape integration

It brings warmth, sustainability and seamless visual integration with nature. It is the preferred solution for natural parks, zoos, eco-resorts and rural settings where shade must respect the landscape.

Computer-aided manufacture

Precision from pattern to cut

Our production technology transfers each design to the fabric with precision, optimising material and preparing every component for accurate installation.

Automated cutting

The design takes shape on the fabric

The machine cuts with precision so every panel matches the dimensions and geometry specified in the project.

Pattern tracing

Geometry defined before manufacture

The pattern is drawn directly on the material so that every component can be checked before cutting begins.

How we work

Consultation and requirements gathering

We listen to the needs of your space. Whether it is an urban climate shelter for a local authority or shade for a school, we assess the visual goals, solar-protection requirements and sector-specific technical standards to establish the best foundation for the project.

Modelling and solar simulation

We engineer the project using specialist software to simulate shade throughout the day and year according to the sun’s path. We calculate wind loads and steel tensions to achieve maximum heat reduction with complete structural safety.

Production and quality control

We move into controlled workshop production, manufacturing the lightweight steel structures and making the HDPE panels with high-strength perimeter reinforcement. We coordinate logistics with the client’s construction or installation programme.

Technical installation and commissioning

Qualified staff carry out the on-site installation while minimising disruption to everyday activity. We tension the sails precisely to activate their thermal properties and deliver a turnkey project with its safety and quality certificates.

What sets us apart

Technical rigour and innovation

Every project undergoes strict tensile calculations and solar simulation. Nothing is left to chance: we combine visually lightweight structures with precise engineering to ensure stability and thermal performance.

Commitment to urban wellbeing

We believe our towns, schools and leisure facilities must adapt to the climate of the future. We design climate shelters that protect people’s health and keep outdoor areas usable even on the hottest days of the year.

Turnkey service

We support public authorities, schools and businesses from the first sketch to the final tensioning of the fabric. We take responsibility for the entire process to ensure an impeccable result and strict adherence to deadlines.
