Euro-Design 70
Where sizes are moderate, a sound baseline is required and unused reserve would add little value.
SYSTEM / COMPARE
Euro-Design 70 covers many practical needs without moving to a more advanced platform. SYNEGO offers more glazing and thermal capacity, but that reserve should be relevant to the actual opening.

TECHNICAL FRAME
Values are configuration references. Final limits and performance must be confirmed by the fabricator for the actual scheme, dimensions, glass and hardware.
| Parameter | REHAU Euro-Design 70 | REHAU SYNEGO |
|---|---|---|
| System depth | 70 mm | 80 mm |
| Glazing range | up to 41 mm | up to 51 mm |
| Frame thermal reference | Uf around 1.3–1.2 W/m²K depending on execution | Uf down to 0.94 W/m²K depending on execution |
| Typical logic | apartments, balconies and homes with moderate requirements | living spaces with higher thermal, acoustic or glazing requirements |
| Design | KALEIDO COLOR and varied opening types | KALEIDO COLOR with greater technical reserve |
DECISION
Where sizes are moderate, a sound baseline is required and unused reserve would add little value.
Where a thicker IGU, greater thermal reserve or a more demanding acoustic build-up is needed.
Reinforcement, glass, spacer, hardware, installation and whole-window Uw.
FAQ
It has more technical reserve, but that may be unnecessary for a small balcony or secondary opening.
No. Depth, reinforcement, glazing, seals, size and installation matter more than a single number.
It depends on glazed area, heating, orientation and target Uw. SYNEGO often gives more freedom for larger living-space openings.
