REHAU / PVC windows and balcony doors
SYNEGO
A versatile 80 mm REHAU platform for energy-efficient windows in new-build and renovation projects, with a broad range of openings, glazing and finishes.

KEY PARAMETERS
Treat SYNEGO as a practical 80 mm platform, not as a collection of record figures.
For most residential openings, sash size, glass build-up and hardware will matter more than the best value in a brochure. We start from the window schedule and then decide where reinforcement is needed, what glass fits and whether another platform is justified.

PROFILE CROSS-SECTION
SYNEGO profile geometry in detail.
This official manufacturer image reveals the system's profile geometry, chambers, thermal breaks and glazing zones. The final junction is selected for the opening scheme, glass build-up, dimensions and project loads.
ARCHITECTURAL USE
Where this system makes sense.
REHAU states that selected SYNEGO configurations can meet Passivhaus requirements for warm/temperate climates. Compliance of the actual element must be checked against the exact build-up.
01
Balanced platform for residential projects
SYNEGO is not intended to imitate minimal aluminium. Its strength is the combination of thermal insulation, airtightness, acoustics and predictable everyday operation in private and multi-residential buildings.
02
Glazing up to 51 mm
The glazing rebate supports modern double- and triple-glazed units, laminated safety glass and enhanced acoustic make-ups after checking total weight and hardware capacity.
03
High weather-performance classes
REHAU publishes air permeability up to class 4, watertightness up to 9A / E900 and burglary resistance up to RC3 for relevant tested configurations.
04
KALEIDO COLOR
Foil, matte, wood-effect and aluminium exterior finishes are available. We coordinate colour with façade cladding, sills, shading and adjacent metalwork.
ENGINEERING
The profile is only one part of the window.
SYNEGO is often a rational choice where strong thermal performance is required without moving to a more expensive composite platform. We compare the complete element — glazing, spacer, reinforcement, hardware, installation joint and thermal base profile — rather than the profile price alone.
How we engineer ↗HOW TO READ THE DATA
Six values that shape the result.
A catalogue maximum is not the rating of every fabricated element. Classes depend on size, opening scheme, glazing, hardware and the tested configuration.
START A PROJECT
We can show where SYNEGO is enough — and where another system is the better choice.
Send a few typical sizes together with the largest sashes. That is usually enough to map the practical SYNEGO range for the project.
