The design of the low threshold, thanks to the level of the floor and terrace, makes it much easier to move between the interior of the house and the terrace or garden. Aligning the threshold with the level of the internal floor eliminates the obstacle in the communication route, ensuring maximum comfort for the residents.
The solution enables comfortable use of the door, ensuring comfortable opening and closing, even with large dimensions. The door operates on the basis of an innovative lift and slide opening system, which gently raises the sash moving on special rollers. Thanks to this, sliding the HST door does not require any effort.
The care for the highest quality of materials and precision of workmanship make the HST patio door a unique and prestigious product. The space obtained by the use of large glazing and the elegance of terrace doors guarantees a beautiful interior. The system allows for the construction of exceptionally large glazing that provides maximum light to the interior, giving it a spacious and stylish character.
