The HS-Portal® sliding terrace door without a lower doorstep is installed directly on the floor. The rail is mounted in the existing coating: marble, ceramic tiles, terrace boards, etc., and is used with any opening scheme.
The problem of the constant sagging of the plastic door prompted the owners to look for a new solution for the entrance.
Their nine years of experience in using the HS-Portal®, Scheme L, suggested a solution: replace the unreliable swing door with the HS-Portal®, Scheme C.
The simplicity of the solution allows you to use a single floor covering in the house and on the terrace. A 16 x 16 mm guide holds the leaves, while remaining almost invisible.
