Lift and slide patio doors - variants


slide patio doors Lift and slide patio doors (HS) by POLIS are a perfect solution if one wants to obtain very wide and high glazing and at the same time the possibility to open the doors. In the case of the easiest variant 'A' /see variants/, the lift and slide patio doors can fit in the opening of more than 6.5 m width and 2.8 m height, which is unheard of in the case of any other solution. Despite the dimensions of the door leaf and its weight, the use of the lift and slide patio doors is very easy and it does not require extraordinary physical strength. By turning a special handle 180 degrees the door leaf is lifted 8 mm as compared to its initial position and it is slid along the running track thanks to roller bearings placed on the sill. As the door leaf is lowered, it gets immobilised so there is no need of additional protection. When the door leaf is lifted it can also be slid outwards. When the door is closed, the door leaf is insulated with the use of a double peripheral seal. The seal along with a well-insulated running track guarantees the state of appropriate thermal comfort. The lift and slide patio doors by POLIS are manufactured with a low-threshold running track, which significantly facilitates the transfer between the house and the terrace, especially when it comes to the disabled. If requested, there is a possibility of manufacturing the tilting doors (HSK), as well as its corner version, in which a free corner of the room is obtained after the two door leaves have been opened. The maximum width of the door leaf – 3300 mm, the maximum height – 2750 mm, acceptable weight – 300 kg.
