Benefits you notice every day
Save indoor space
The sashes move along tracks rather than swinging into the room.
Threshold option
A flush-threshold assembly can be assessed with the surrounding flooring and drainage.
Simple surface care
PVC does not rust or need repainting. Clean it and maintain the tracks, seals and hardware.
Two or three tracks
Choose a compatible layout with moving sashes or a separate insect-screen track.
Recyclable PVC
The manufacturer quotes an average recycled content of 45%; suitable profiles can be recycled at end of use.
What's inside your window
Recessed shutter strap winder
The frame allows a compatible roller shutter strap winder to be recessed.
Replaceable seals
Compatible EPDM/TPE seals can be renewed when necessary.
Closed frame reinforcement
The specified reinforcement helps support the assembly’s dimensions.
Two-part central connection
A central connection designed for the specified window or door assembly.
Assemblies up to 3500 × 2400 mm
The stated three- or six-sash layouts permit these maximum overall dimensions.
Central-profile options

When to compare a higher-performance system
If the opening’s insulation or exposure requires a different assembly, compare Ekosol with Vekamove 76, which uses a continuous central seal, or an appropriate lift-and-slide system. The choice depends on the exact opening and its requirements.
Ekosol terrace and utility-balcony enclosures
Its two- and three-track layouts can be considered for terrace and utility-balcony enclosures, within the stated overall dimensions. The frame, reinforcement and connection to the surrounding structure are checked for each project.
A compatible recessed shutter strap winder can be incorporated where a roller shutter is part of the assembly.
Compare complete sliding-window specifications
For an opening between a conditioned room and the outside, we compare the required thermal and weather performance with Vekamove 76 or Vekaslide Hi-5. Reference Uw figures refer to their stated glass and test assemblies, so they should not be compared by the frame alone.
Frequently asked questions
Can Ekosol be specified with a roller shutter?
Yes. The frame can incorporate a compatible recessed strap winder and be assessed with a suitable monoblock shutter box.
What acoustic value is quoted for Ekosol?
The stated reference test quotes Rw 30 dB for windows up to 2.7 m². Where more acoustic performance is required, we compare suitable glazing and other complete window systems.
Can Ekosol be used as a balcony door?
Yes, within the relevant system limits. The optional flush threshold is assessed with the flooring, drainage and intended access.
Can Ekosol include an insect-screen sash?
A suitable three-track layout can reserve a track for an insect screen. We confirm the complete layout and dimensions before ordering.
