Wingum Plus H₂O: liquid waterproofing meets UNI 11928-1
What is UNI 11928-1 and why does it matter?
Introduced in 2023, UNI 11928-1 is a game-changing regulation for the construction industry. For the first time, site-applied liquid waterproofing membranes are officially recognized as equivalent to prefabricated membranes—with clear, performance-based criteria.
This opens up more flexibility for designers, contractors, and builders who need solutions that are:
Certified
Durable
Versatile
Easy to apply
And that’s exactly what Wingum Plus® H₂O by Winkler delivers.

Why choose Wingum Plus® H₂O from a UNI 11928-1 perspective?
- Ease of installation and maximum versatility on any surface: one of the strengths of Winkler liquid waterproofing systems is their ease of application.
“Wingum Plus® H₂O is easily applied thanks to its liquid formulation, which allows uniform coverage even on uneven surfaces, without gaps or joints. This represents a real advantage over traditional waterproofing systems.”
- The versatility of the Wingum Plus® H₂O range allows for continuous waterproofing on a wide range of substrates, such as metal, wood, brick and fiber cement, making it ideal for building upgrades as well. In addition, the quick and non-invasive installation minimizes time and inconvenience on the construction site, offering an effective solution even in complex environments or on difficult surfaces.
- Full regulatory compliance: the products meet the requirements for each intended use, whether exposed or protected.
- Sustainable solutions: all versions are water-based, solvent-free, with very low VOC content (e.g., 12.90 g/L).
Conclusions: the UNI 11928-1 standard opens up the market. Wingum Plus® H₂O revolutionizes it.
UNI 11928-1 represents a breakthrough for designers, companies, and applicators: at last, an unambiguous performance classification for liquid waterproofers. Winkler ‘s Wingum Plus® H₂O range fits perfectly into this context, offering concrete, certified and sustainable solutions.
As Leonardo Castelvecchio, Winkler sales technician, points out, “With Wingum Plus® H₂O we bring to the construction site an evolved technology designed for those looking for application simplicity, regulatory reliability and real performance over time. The new standard gives us the framework, but it’s the products that make the difference.”
FAQ
What changes with the new UNI 11928-1 standard for liquid membranes?
The UNI 11928-1 standard officially recognizes liquid-applied membranes as technical solutions equivalent to prefabricated sheets. It establishes specific performance requirements based on the intended use (e.g., exposed roofs, protected roofs), thereby guaranteeing their quality and reliability.
Why is the Wingum Plus® H₂O range an ideal solution according to the new standard?
Because it offers specific and certified products for each application area covered by the standard: from standard walkable roofs to those with fire resistance requirements for photovoltaic systems (Broof T2) or high solar reflectance (Reflex).
Is there a safe liquid membrane for roofs with photovoltaic panels?
Yes, the Wingum Plus® H₂O BROOF T2 product is ideal for this purpose. In addition to waterproofing, it offers certified protection against external fire (BROOF T2), a fundamental safety requirement for roofs with photovoltaic systems.
