Hi-Finity Open Corner

Hi-Finity Open Corner

The infinite view

This extension of the Hi-Finity system is a creative open corner solution. This solution is characterized by the absence of a corner profile, allowing the sliding elements from both sides of a corner to open without obstacles. This solution addresses both accessibility and design needs in both double and triple glazing.
