DURABLE 88 Series Soundproof Sliding Window
- CE EN 14351-1
- NFRC
- Passive House (PHI)
The 88 Series slider moves large panes on stainless twin-track rollers behind an integrated stainless security mesh, so ventilation and protection come together. Slim interlock profiles keep the view open while the 88 mm thermal-break frame holds the line on energy and noise.
