Oknoplast HST PREMIUM A SCOMPARSA Lift and slide PVC patio door

HST PREMIUM A SCOMPARSA French windows are designed with the aim of optimising space near accesses to terraces and gardens.‎ They allow you to avoid the clutter of a traditional hinged opening, and at the same time enjoy a large glass surface area that increases the brightness of rooms, creating continuity between indoor and outdoor spaces.‎ The unique concealed system allows the sash to slide inside the wall, leaving more space for furniture.‎ Another feature of the concealed HST PREMIUM A SCOMPARSA is the special low threshold, which is highly thermally insulating and perfectly watertight.‎ The optional micro-ventilation system, which clips onto the frame, allows for air exchange without sacrificing the security of the closed window.‎ TECHNICAL SPECIFICATIONSPROFILE ● Class A profile, 170 mm wide, thanks to its special construction with 3 mm external walls, ensures that the best thermal and acoustic insulation parameters are maintained, guaranteeing the doors a long life and stability over time ● The profile reinforcements are made from high quality aluminium profiles and are a key element in the durability and functionality of HST doors, guaranteeing their rigidity and many years of perfect operation THERMOLINE GLASS ● Thermoline insulating glass with thermal transmittance coefficient U=10 W/m2K ● Triple-glazing U=0.‎7 W/m2K is available on request HARDWARE ● Sliding windows that allow even large sashes to be moved with extreme ease and minimum effort GASKETS ● EPDM (Ethylene-Propylene-Diene Monomer) with high resistance to atmospheric agents such as humidity, water vapour, UV rays or temperature changes.‎ They are available in three colours (black, grey and brown) to match the window colours THERMAL INSULATION ● Thermal transmittance of the door Uw= 1.‎2 W/m2K with a stainless steel thermal frame or 1.‎3 W/m2K with a standard aluminium frame; 1.‎0 W/m2K with triple glazing ACOUSTIC INSULATION ● Rw (db) = 33 ONREQUEST ● Possibility of adopting a noble steel thermal frame that eliminates the so-called thermal bridge, reducing heat loss ● Burglar-proof hardware in class RC2 which contributes significantly to the protection of the house against burglary attempts ● Mesh micro-ventilation system that combines ventilation comfort with high burglary protection
