Exceptional thermal and acoustic performance

The 4700 RPT sliding window stands out for its excellent thermal and acoustic performance. Thanks to its design and the materials used, this window offers a Uw transmittance value as low as 1.1 W/m²K, which contributes to better thermal insulation and reduced heat loss inside living spaces. This level of energy efficiency helps to maintain a comfortable indoor temperature all year round, reducing dependence on heating or cooling systems.

In terms of sound insulation, the 4700 RPT sliding window ensures a quieter and calmer indoor environment. Thanks to its ability to accommodate glazing up to 36 mm thick, this window can achieve a maximum sound insulation of 40 dB. This means that it significantly reduces the transmission of unwanted external noise, creating a more serene and comfortable indoor environment.

A world of possibilities for openness

The 4700 RPT sliding system offers various opening possibilities, adapting to the needs and preferences of each project. The available options include:

  • Sliding: the standard configuration of this system, which allows the leaves to slide sideways.
  • Monorail (leaf + fixed): ideal for spaces where an additional fixed leaf is required next to the sliding leaf.
  • Bi-rail: perfect for spaces that require two sliding leaves that move in opposite directions.
  • Three-rail: this option allows three sliding leaves to be incorporated into a single system, providing greater flexibility and openness.
  • Galandage: an innovative alternative that allows the sliding panels to be completely concealed within the walls, maximising usable space and creating a minimalist aesthetic.
