What it is
Lift-and-slide doors
An Ultraglide version designed for a lower threshold and easier access.
Role in the project
Ultraglide low threshold
The low-threshold version of Ultraglide uses its own profile section and must be coordinated with the floor detail.
What to consider
Purpose and limitations
A low threshold only gives a fully level or watertight detail if the floor and drainage are designed for it.
Five Ultraglide variants for different projects
Choose the layout, threshold, corner or thermal assembly
The Ultraglide versions are not ranked by quality. The basic system, the low threshold, the corner solution, Monorail and Thermo suit different project conditions, and each version has its own geometry.
01
Technical system name
Standard sliding and HST platformUltraglide
The versatile Ultraglide base for sliding and lift-and-slide layouts in large glazed openings. Final weight, size, number of tracks and operation are confirmed for the specific configuration.
View version02This systemTechnical system name
Easier access with a low thresholdUltraglide low threshold
Choose this version when a lower step-over height is an important requirement for the project. A low threshold alone does not guarantee a fully level, barrier-free or watertight detail; that also takes a properly designed floor and drainage.
This system03Technical system name
Glazed corner that opensUltraglide corner system
The corner solution lets the sashes slide away and open up a 90° corner. It is not a fixed glass corner; the sash order, the choice of two or three tracks and the number of units depend on the specific layout.
View version04Technical system name
One sliding track and a dedicated fixed lightUltraglide Monorail
Monorail separates the active sliding sash from a purpose-built fixed light. It has its own asymmetric frame and is not interchangeable with the standard Ultraglide or the Inferno Monorail cross-section.
View version05Technical system name
Ultraglide assembly with improved thermal performanceUltraglide Thermo
Thermo is chosen when thermal requirements call for a deeper frame, a sash depth of 77 mm and a wider range of infills. It has its own profile assembly, which is checked for the specific unit.

Key points about the system
Whether the opening is fully accessible depends on the construction detail and the applicable local standard; a low threshold on its own is not enough.

Before the final specification
What is the Ultraglide low threshold system?
An Ultraglide version designed for a lower threshold and easier access.
What is the Ultraglide low threshold system designed for?
The low-threshold version of Ultraglide uses its own profile section and must be coordinated with the floor detail.
What should you consider when choosing the Ultraglide low threshold system?
A low threshold only gives a fully level or watertight detail if the floor and drainage are designed for it.
Is all the technical data the same for every version?
Sizes, glass, hardware, structural calculations, threshold and opening type are confirmed for each individual opening – only then can the system be tailored to your LUMORA project.
