A sliding window system adapted to the latest aesthetic trends, offering a balanced price and excellent sealing performance. Its assembly is quick and simple, making it one of the most widely used sliding systems—especially recommended for small to medium openings.
Perimeter sliding system with thermal break (RPT) and a 70 mm frame, offering strong performance in lab testing and fast, simple manufacturing. Particularly suitable for sliding windows and balcony doors up to 2300 mm in height.
Test bench performance:
According to the CTE (Spanish Technical Building Code), which sets minimum thermal performance requirements based on geographic location, this series is suitable for all climate zones. However, for zones D and E, an insulating glass is recommended.
To improve sealing and thermal/acoustic insulation, the system includes a patented inverted U-shaped polyamide profile that allows drainage along the entire length of the bottom frame—not just the exterior-facing section. This innovation is patented and incorporated across the entire range of sliding systems.
Bearings use needle rollers and come in both single and tandem versions. All are vertically adjustable, and the tandem version supports up to 150 kg per sash. Bearings can be replaced without opening the sash. For more information on bearings, visit: www.woorbel.com
The frame profiles feature a clipping system that allows for easy positioning of auxiliary profiles such as trim caps, drip edges, or frame connectors.
Innaltech supplies the full range of accessories for this system. All our systems are fully digitally integrated for material breakdowns, cut optimization, fabrication sheets, and CE marking labels. Cutting and machining can also be automated on machining centers. The software is available in Spanish, Catalan, and French.
