FRP family · XD75 series
A 75mm hybrid platform that keeps aluminium inner and outer shells while replacing a conventional narrow polyamide break with a 45mm pultruded glass-fibre reinforced polyurethane structural thermal core. Two opening configurations share one qualified system family.
XD75 is a hybrid aluminium-composite system, not a full-FRP frame. Its inner and outer aluminium shells are structurally joined by pultruded GRPU thermal components. PINDÉ therefore manages XD75 under the FRP engineering programme, with composite-material traceability, connection testing and project-specific whole-window verification.
The sash opens outward to preserve usable interior space. Straight inner and outer sightlines, a European C-groove hardware interface and dry-glazing gaskets support repeatable local fabrication.
The inward-opening sash supports both full opening and tilt ventilation. In tilt mode, ventilation remains available while helping limit direct rain entry.

The source system catalogue reports the following values for the listed glazing build-ups. They are reference results for the catalogue specimen, not automatic ratings for another size, glazing package, fabrication route or national standard.
| Catalogue glazing | K-value / grade | Wind | Air | Water | Acoustic |
|---|---|---|---|---|---|
| 6Low-E + 12Ar + 6 | 1.84 W/(m²·K) · Grade 7 | Grade 9 | Grade 8 | Grade 4 | Grade 4 |
| 6Low-E + 12Ar + 6Low-E + 12Ar + 6 | 1.31 W/(m²·K) · Grade 8 | Grade 9 | Grade 8 | Grade 4 | Grade 4 |
Qualification gate: final thermal, air, water, wind, acoustic and durability claims must be confirmed for the ordered window size, glass, warm edge, hardware, joints, installation node and destination-market test method. Catalogue values must not be reused as a project guarantee.
