HST 85 mm lift and slide doors

HST 85 mm patio doors are a window solution that will make your dream home full of light, free from architectural barriers, close to the surrounding nature, and at the same time comfortable, warm and safe.

These large-area windows allow you to eliminate all restrictions, save space and freely shape the space in your home. They are an ideal solution for those who want a comfortable combination of the interior with the terrace and a panoramic view.

Panoramic views

HST sliding doors are the only window constructions that allow you to create large-size glazing, providing a unique view of the space around the house. The width of the leaf can be from 800 mm to 3000 mm wide and up to 2700 mm high in white, which allows you to create even more than six meters of glazing.

A home without barriers

HST doors are a modern and safe solution, designed to eliminate ubiquitous barriers. The low door threshold with a height of 48 mm, which can be recessed from the side of the room in its entire height, meets the requirements for construction without architectural barriers and allows trouble-free entry and exit. Thanks to this solution, it is also possible to align the threshold with the floor surface and thus completely eliminate architectural barriers.

HST 85 mm Fixframe - even more light

HST 85 fixframe with a very narrow frame in the fixed-glazed part is the fulfillment of the postulate of maximizing glazed areas, increasing the amount of light entering the rooms and effective use of thermal energy from the sun.

The particularly narrow profile in the fixed glazing ensures even greater light penetration into the living space - for a high quality of life and additional solar heat gains!

Functionality and comfort of use

Special hardware mechanisms allow you to move huge sashes with minimal force. Turning the large handle down, from the closed position, raises the sash by a few millimeters, releases the pressure of the seals and allows the sashes to move freely, which without the slightest resistance move relative to each other or to non-opening parts of the structure.

Many opening variants

HST 85 mm lift-and-slide doors can be available in at least several different versions and arrangements of leaves and non-opening parts. The most popular HST door schemes are 2-panel variants - with one or both movable leaves - or 4-panel variants - with two middle or all movable leaves.

Space harmony

HST doors are an excellent alternative in terms of space arrangement in relation to classic balcony doors, which, after opening the wings, go deep into the living space. Despite the greater depth of the building than the classic balcony door, it is the HST door that leaves more freedom in the disposal of space.
