In this guide we take a closer look at the Linear\u00ae pocket frame and its role within Protekdesign\u2019s Linear collection, the expression of a design approach focused on continuity and freedom of space. We also look at the range\u2019s three finishes \u2013 FiloSoffitto, FiloBattuta and CoverColor \u2013 with dedicated insights.<\/p>\n

In short<\/p>\n

For Protekdesign, every flush-to-wall pocket frame starts from a precise idea of spatial architecture: making what separates rooms invisible, leaving the wall continuous and the design free.<\/p>\n

A flush-to-wall door has no visible jambs or architraves and, when closed, blends into the wall surface without visible interruptions. On a plasterboard partition, this result requires a pocket frame specifically designed for dry installation from the moment the structure is assembled, not a normal masonry frame.<\/p>\n

Protekdesign\u2019s Linear\u00ae is the pocket frame for a single flush-to-wall sliding door, developed specifically for plasterboard. A solution that turns the principle of invisible space into a concrete, high-performance system: aluminium structure, 150 kg standard load capacity, openings up to 120 cm and a 25-year guarantee.<\/p>\n<\/div>\n

A flush-to-wall door<\/strong> is a door with no visible jambs or architraves: the frame stays integrated within the thickness of the wall and, with the leaf closed, the surface keeps its continuity.<\/p>\n

On a plasterboard partition, this result cannot be achieved with a normal masonry frame, but with a pocket frame designed for dry installation from the moment the structure and boards are assembled.<\/p>\n

Linear\u00ae is Protek\u2019s pocket frame for a single flush-to-wall sliding door, designed specifically for plasterboard walls. The aluminium structure, ceiling track and strike jamb are built into the thickness of the wall, eliminating traditional jambs and architraves.<\/p>\n

Let\u2019s look in detail at why Linear\u00ae is particularly suited to a plasterboard wall, how it differs from a hinged flush-to-wall door and which finishes define the relationship between door and wall.<\/p>\n

Why choose Linear\u00ae for plasterboard walls<\/strong><\/h2>\n

Structure and fixing in plasterboard<\/strong><\/h3>\n

Linear\u00ae for plasterboard walls is a pocket frame made of high-strength galvanised steel sheet and extruded aluminium.<\/p>\n

The frame structure is aluminium, with large multi-chamber extruded profiles, while the side sheets have horizontal ribs every 100 mm that also serve as support for fixing the plasterboard sheets.<\/p>\n

This configuration reduces leverage and allows more effective fixing of the boards, adding to the solidity of the whole system.<\/p>\n
