A comfortable lift & slide door system that enables the creation of impressive glazed structures. Its installation requires excellent technical and technological knowledge. Thanks to the low profile,  EkoSun HST provides maximum light to the room and aesthetics at the highest level. Lower PVC profile together with larger glazed surfaces improve the thermal performance of the windows.

EkoSun HST system is available with a low level threshold (50 mm) as standard. It is enough to lift and move the movable sash of the HST window so that both floor levels – external and internal – form one plane. Thanks to this, the space becomes open and elegant. A low level threshold guarantees effective thermal insulation, trouble-free movement for people with disabilities and small children and trouble-free maintenance thanks to removable profiles. It also allows for trouble-free modernisation of lift and slide doors.

On request, there is an additional option available: a 50 mm level threshold with a linear drainage. It is an additional gutter placed on the outer side of the sliding system, that helps to effectively drain even large amounts of rainwater and get rid of accumulated impurities, such as: leaves, sticks or small twigs.
