Contemporary landscape architecture is placing increasing emphasis on harmoniously combining aesthetic qualities, functionality and the idea of sustainability in the design of public spaces. Facilities such as lakeside piers, observation towers and walking piers are key elements of tourist infrastructure, which perform not only recreational, but also educational functions, introducing visitors to the unique natural and cultural values of a given region.

Synergy of aesthetics and functionality
The design of public buildings requires the use of materials that will ensure many years of use while meeting rigorous construction and aesthetic standards. Twinson decking systems, manufactured by Deceuninck, respond to these needs by combining innovation with durability.
Twinson Character Massive and Twinson Majestic Massive Pro composite decking are distinguished by their versatility of use and aesthetics adapted to a variety of architectural designs. Their lightweight construction (less than 30 kg/m²) allows them to be safely used on structures with limited load-bearing capacity, such as piers or viewing platforms, while maintaining their strength.

Safety in use and resistance to external factors
The operation of public facilities involves heavy foot traffic and exposure to the elements, which places high demands on finishing materials. Twinson boards, manufactured using coextrusion technology, are characterized by minimal water absorption and low linear expansion, ensuring durability and dimensional stability. They are produced from a composite with a density of at least 1485 kg/m³, based on polyvinyl chloride (PVC) and softwood flour, which accounts for their durability under heavy use.
The high softening temperature according to Vicata of 80 degrees Celsius proves that boards made with PVC matrix retain their hardness and scratch resistance under conditions of intense sunlight. Moreover, their modulus of elasticity of at least MPa ≥ 2000 ensures durability and resistance to cracking at low temperatures.
Tests conducted by the Building Research Institute have shown exceptional load resistance, confirming the safety of use even under heavy foot traffic. A section of Twinson Character Massive plank flooring subjected to pressure realized by two hydraulic cylinders and transmitted through a steel grate to the plank surface withstood a load of 87.7 kN/m², equivalent to about 8.7 t/m².
An important feature of Twinson planks is slip resistance - the PTV coefficient is as high as ≥ 55, with a minimum permissible value of ≥ 36. This indicates, high safety of movement on the surface, both dry and wet. In addition, a high solar reflectance index (SRI) minimizes surface heating on sunny days. Surfaces with a higher SRI remain noticeably cooler than those with a lower index, even with the same UV exposure. The use of Twinson boards, especially in the colors 522 "walnut" (SRI 24.3 ±1.1) and 509 "gray" (SRI 17.6 ±0.8), effectively reduces the so-called "heat island" effect. This is especially important in intensely sunny areas, such as piers and viewing platforms, providing greater thermal comfort for users.

Fire resistance in public infrastructure
Fire safety is a key aspect in the design of public infrastructure. Twinson planks, which have a fire reaction class of Bfl-s1, are distinguished by their low flammability and lack of smoke or burning particle emissions. This is particularly important in the context of the risks associated with the intensive use of piers and walking paths, as confirmed by recent cases of fires in such facilities in Poland. The fire-resistant properties of Twinson boards effectively minimize the risk of fire spreading in similar situations. Even in the case of intentional arson, they will extinguish spontaneously once the source of the fire is burned out, and the fire will not progress.

Certified materials for sustainable construction
Twinson products are manufactured according to the principles of the circular economy, using certified wood (PEFC) and technology that minimizes CO2 emissions. An Environmental Product Declaration (EPD) and reports confirming the absence of volatile organic compound (VOC) emissions are proof of care for the environment and users. In addition, Twinson boards are fully recyclable, and their high durability translates into many years of use without costly maintenance.
The products are also distinguished by a long warranty period: 10 years against technical defects, 25 years against biodegradation, and an exceptional warranty for Majestic Massive Pro boards - 10 years for color stability. Their quality has been confirmed by the National Technical Assessment of the Building Research Institute (KOT), as well as the Broof t1 external fire resistance of the pavement. What's more, Twinson planks have the Hygienic Certificate of the PZH, which further emphasizes their safety in use.
Twinson composite planks are manufactured by Deceuninck in the European Union, using appropriate raw materials so as to meet high quality standards and minimize the emission of CO2 and other compounds into the atmosphere.
The quality of production and components are confirmed by relevant documents:
-
EPD (Environmental Product Declaration), which evaluates the environmental impact of the material during production, packaging, transportation up to disposal and recycling.
-
PEFC certificate for the wood used in the production of the composite (Forest Certification Systems Approval Program).
-
Report confirming that the finished product does not emit VOCs (volatile organic compounds).
-
Long warranty period: 10 years against technical defects, 25 years against biodegradation, and a unique warranty for Majestic Massive Pro boards: 10 years for color stability.
-
National Technical Assessment from the Institute of Building Technology (KOT).
-
Fire reaction class Bfl s1.
-
Resistance of the surface to external fire Broof t1.
-
Hygienic certificate of the National Institute of Hygiene.
