Oknoplast HST Premium patio doors

Natural light is indispensable to us. Its benefits are countless: it improves morale, stimulates alertness, regulates the internal clock or synchronizes sleep.

To let this natural light flood into our interiors, OKNOPLAST, a European leader in PVC windows, doors and shutters, has put all its know-how into the design of a revolutionary new window with a contemporary, narrower profile (with a 70mm frame) and with enlarged clear glazing: the PIXEL

OKNOPLAST BAY WINDOW, HST RANGE

Oknoplast is a manufacturer of windows and other PVC joinery. This joinery specialist, established in France since 2009, innovates in PVC windows and doors through the so-called “HST” opening technology. HST is a patented Oknoplast “lift and slide” technology.

This new technological innovation greatly facilitates daily use because it ensures excellent stability and lightweight operation. HST sliding systems are ideal for large glass surfaces.

COMBINATION OF COMFORT AND INNOVATION

Oknoplast innovates and offers a bay window or a sliding French door suited to all houses.

This range uses the “lift-slide” technology, also called “HST”, i.e. the sashes are mounted on two rails, which allows sliding without overrun from one sash against the other. This combination of comfort and innovation is the solution that will bring maximum light to the home. This technology makes it possible to obtain up to 11 m2 of glass surface. The width of the sashes can reach 2.5 meters, or a passage of 2.3 meters.

Oknoplast’s HST sliding range adapts to all types of interiors. The straight curves can thus blend perfectly into the home. The HST bay window can be personalized thanks to a wide range of natural colors but also thanks to the accessories associated with it. The accessories in the HST range are window handles with classic or timeless designs as well as numerous glazing units. The HST range will give your home character.
