Industrial Roof Waterproofing for D’orica Gioielli, Vicenza with WINGUM PLUS® H2O BROOF t2
Industrial roof in Vicenza waterproofed with WINGUM PLUS® H2O BROOF t2 by Winkler: fire safety, durability, and uninterrupted photovoltaic operation.
Industrial Roof Restoration with Winkler Systems in Vicenza
Case Study – Gold Jewellery Industry, D’orica Gioielli
In Vicenza’s renowned gold jewellery district, D’orica Gioielli needed to restore the waterproofing of an industrial roof measuring approximately 1,100 m².
Project Objectives
The intervention was designed to achieve:
- Restoration of waterproof integrity across 1.100 m2
- Compliance with BROOF t2 fire resistance class
- Protection of photovoltaic panels and anchoring points
- Improved thermal efficiency through high-reflectance finishing
- Full operational continuity through cold-applied systems
Technical Challenges of the Industrial Roof
Traditional torch-applied membranes would have introduced fire risk and required partial shutdown of the photovoltaic system.A safe, seamless, cold-applied, and fire-certified solution was essential.
WINGUM PLUS® H2O BROOF t2 Waterproofing System
To meet all technical and regulatory requirements, the solution selected was WINGUM PLUS® H2O BROOF t2 — Winkler’s water-based, fiber-reinforced liquid membrane formulated with high-performance modified resins.
Applied System Layers
1. WINSEAL – Adhesion Primer
Creates strong chemical and mechanical adhesion to the existing surface
2. BC SEAL PAD – Self-Adhesive Butyl Sealing Tape
Reinforces critical areas such as joints, edges, penetrations and overlaps
3. WINTECHNO MAT – Non-Woven Reinforcement Fabric
Adds mechanical strength and ensures uniform membrane thickness
4. WINGUM PLUS® H2O BROOF t2 (White)
Provides a reflective, fiber-reinforced waterproof barrier with verified fire safety performance and improved solar reflectance for enhanced thermal efficiency
Technical and Performance Benefits
- Perfect adaptability to roofs with photovoltaic installations
- Full adhesion eliminates under-membrane infiltration risks
- Cold application increases safety and reduces installation time
- High durability under mechanical and thermal stress
- Certified BROOF t2 fire performance ensures regulatory compliance
- Reflective surface improves building energy performance
Results Achieved
This case study demonstrates how Winkler liquid systems combine safety, sustainability, and technical excellence for industrial roofs with photovoltaic installations.
FAQ – Frequently Asked Questions
What is BROOF t2 certification?
It is the external fire resistance classification defined by UNI EN 13501-5, mandatory for roofs with photovoltaic systems to prevent fire spread.
Can the system be applied over existing roofing?
Yes. Thanks to WINSEAL primer, the system bonds to existing substrates, preventing demolition and reducing costs.
Is the membrane reflective?
Yes. The white version of WINGUM PLUS® H2O BROOF t2 is certified with Solar Reflectance Index SRI 108 by the Cool Roof Rating Council.
Is the system cold-applied?
Yes. It is completely cold applied, eliminating fire hazard and allowing uninterrupted photovoltaic operation.
Is the system resistant to ponding water?
Yes. Its fiber-reinforced formulation ensures long-term performance even on low-slope roofs with occasional water stagnation.
