One step further in comfort, a leap in quality

4900 HI Sliding System: The sliding solution that represents a qualitative leap over the 4700

The 4900 HI is the ideal option for those who want to take a step beyond the 4700 sliding system. It retains the philosophy of comfort, smooth operation and balanced design, while introducing improvements that are noticeable from the very first use: better insulation, greater stability and an overall superior sense of quality with every opening.

This series is designed for homes that require a higher level of comfort. While the 4700 already represents an improvement over older systems, the 4900 HI further enhances thermal and acoustic performance, creating more stable, quieter and more pleasant living spaces—even in areas especially exposed to weather conditions or noise. It is the perfect solution for those who notice that their home loses heat quickly or that certain rooms are particularly sensitive to external changes.

In addition, the user experience takes a noticeable step forward. The 4900 HI delivers even smoother sliding and more precise closing, with an optimized structure that reduces opening effort and provides a level of stability that is felt day after day. It is a sliding system designed for intensive use, where every movement conveys solidity and comfort.

In terms of aesthetics, the 4900 HI features a more refined finish than the 4700. Both are modern, but the 4900 HI has a more solid and elegant presence, delivering a more noticeable visual upgrade without the need for minimalist or large-format systems. It combines contemporary design with a sense of quality that is evident in the details.

Improved performance without the complexity or cost of a premium system

The 4900 HI delivers a real step forward in efficiency and comfort while maintaining the versatility and ease of integration of the 4700. It is the perfect solution for those looking to significantly improve the performance of their sliding system without moving into higher investment ranges or more demanding construction solutions.

Even smoother sliding and more precise closing

Although both sliding systems are known for their ease of use, the 4900 HI incorporates improvements in seals and mechanisms that result in lighter, quieter operation and a more secure closing. Each opening conveys a superior sense of quality, especially noticeable with continuous daily use.

Clearly superior thermal and acoustic insulation

The 4700 already provides a good level of comfort, but the 4900 HI is specifically designed to enhance insulation, keeping the home more stable against heat, cold and noise. It is the ideal option for homes where temperature fluctuates easily or where outdoor noise can cause disturbances.

More refined aesthetics and a more “premium” visual feel

The 4700 is modern and well-balanced, but the 4900 HI goes one step further with a more elegant, solid finish and cleaner lines. Its presence enhances the overall look of the space without the need to resort to minimalist sliding systems or large-format solutions.
