DECALU 88 HIDDEN

The „hidden sash” system incorporates all the features of the basic DECALU 88 STANDARD solution while ensuring optimal aesthetics for such applications. An additional advantage of the DECALU 88 HIDDEN system is the ability to glaze glass of various thicknesses using glazing clips employed in the standard version without the need to change sash profiles. The movable mullion for „hidden sash” solutions has a minimum visual width of 111mm. The system offers fixed mullion solutions for configurations like sash-sash, sash-fixed glazing, fixed glazing-fixed glazing.

Features of the IMPERIAL SU system (concealed sash):

– A three-chamber window system with thermal insulation designed for constructing windows with a concealed, invisible sash from the outside.
– The system is characterized by a specially designed frame shape that conceals the entire height of the sash profile.
– A wide range of glazing options allows for the use of all commonly encountered types of single or double-glazed glass, as well as acoustic or anti-burglary glass.
– Drainage profiles are available in two variants: traditional and concealed.

– The ability to bend profiles.
– The concealed sash system is the preferred choice among designers, allowing for „concealed windows” in aluminum and glass structures. This solution ensures that both outward-opening and fixed windows look identical from the exterior.
– The IP SU system is available in a version with enhanced thermal insulation, and there is an option for IP SUi with insulation around the glass perimeter.
– A wide range of color choices is offered, including the RAL palette (Qualicoat 1518), structural colors, wood-like colors in the Aliplast Wood Colour Effect (Qualideco PL-0001), anodized finishes (Qualanod 1808), and bicolor options.
