SMOOVIO is the newest and most modern sliding plastic door in Europe. The door is very airtight and comfortable. As living space is priceless, it should be used to the best advantage. The combination of the latest GEALAN profiles and the specially developed ROTO locking mechanism, together with a new generation of seals, allowed us to bring the highest quality sliding doors to the market. The Smoovio door is a parallel sliding system, it is cheaper than a parallel sliding (HST) system and somewhat more expensive than a slant-sliding (PSK) system. Smoovio sliding doors are one of the most popular products we sell.
