Advanced Engineering for Laminated Glass & Composite Materials
Developing a new glass product? Optimising a production process? Facing a structural challenge your team cannot crack? We bring the modelling, testing, and validation expertise to get it done. Faster time-to-market. Lower risk. Stronger products.
We Solve Problems Your Team Shouldn't Have To
New Product Development
Launching a new interlayer, a laminated glass product, or a facade system? We handle the modelling, testing, and material data your certification process requires so your R&D team can focus on getting to market faster.
Expertise You Don't Have In-House
Viscoelastic modelling, fractional calculus, DMTA characterisation, custom FEM solvers. Specialised skills that are hard to hire for. We plug the gaps in your capabilities or integrate directly with your engineering team, on demand.
Reduce Cost, Reduce Risk
Better models mean fewer prototypes, fewer failed tests, and fewer surprises on site. We help you make the right design decisions early, saving time and money downstream.
The Team Behind Fractan
Lorenzo Santi, PhD
Co-Founder — Structural Mechanics
PhD in Industrial Engineering, University of Parma. Research engineer at Saint-Gobain Research (France) and Kuraray Europe (Germany), working on interlayer characterisation and laminated glass performance. He leads Fractan's structural mechanics and viscoelastic modelling capabilities.
What We Deliver
Concrete solutions for product development, structural verification, and regulatory compliance.
Structural Analysis of Laminated Glass Systems
Need to verify a facade design, a balustrade, or a structural glass floor? We deliver accurate long-term performance predictions that account for real interlayer behaviour, not simplified assumptions. This means fewer design iterations, confident regulatory submissions, and products that perform as expected.
Discuss a projectThermal Performance
Temperature differences across laminated glass generate stress through differential thermal strain. We model these effects under real solar loads, seasonal swings, and shadow patterns, giving you validated predictions so you can optimise your design before it reaches the construction site.
Discuss a projectInterlayer Characterisation & Material Modelling
Launching a new interlayer or need reliable material data for an existing one? We run DMTA tests, bending tests, and full characterisation campaigns for PVB, SGP, EVA, TPU, and multi-material composites. You get experimentally validated material parameters ready for product certification, simulation input, or technical datasheets.
Discuss a projectCustom FEM Development & R&D Consulting
Off-the-shelf software not cutting it? We build custom simulation tools tailored to your specific product or process, from automated parametric studies to specialised solvers for layered structures. Every tool is validated against laboratory data and designed to give your R&D team a lasting competitive advantage.
