Technal LUMEAL Sliding System


Technal LUMEAL Sliding System

Technal LUMEAL is a minimalist sliding system with a concealed opening sash. Its minimalist design optimizes natural light and ensures an 8 to 14% gain in glass surface area depending on the application.

LUMEAL can be used to create different opening configurations combining a fixed section and sliding section, associated with a slim central meeting stile. The slider has a distinct refined finish with no overlapping of profiles and concealed drainage. Square-jointed assembly also helps to refine the structure.

This system offers a real solution for low energy building projects due to its very low air permeability and outstanding thermal performance.

  • Lighter aluminium weight (-35%) with only 68 mm and 77 mm of visible aluminium
  • Slim central meeting stile of 38 mm
  • Concealed drainage for all applications

Motorized option for more comfort and accessibility

  • Motorization allowing automatic lateral displacement and locking/unlocking of the operating sash
  • Motorization system fully integrated to the slider to keep LUMEAL high performance and aesthetic
  • Easy and noiseless lateral displacement: speed around 15 cm/s (according to the size of the sash)
  • In case of obstacle, the sash stops and goes back to release
  • Large dimensions (frames up to 4 meter long)
  • International use thanks to tropical circuit board running in 100% relative humidity atmosphere


Security / Forcible Entry Delay

LUMEAL sliding system, resistance class level 3 (RC3) against burglary according to the European norm EN 1627-30, by resisting more than 5 minutes to an attempted break-in. Locking system inaccessible from the outside, with either non-locking or 2-point and 3-point locking.

Site Procedure 1: Sub-frame Stage

Installation of Sub-frame
– Sub-frame is cut into size on site
– Corner joint is used for ensuring the perpendicularity of sub-frame
– Galvanized strip and Hilti products are used to fix the sub-frame to the wall structure
Advantages of Sub-frame system
– Generally has better water tightness performance
– Can be used for precast or cast in-situ wall systems which do not require plastering
– Allow greater flexibility in the sequencing of works of other trades; the sub-frame is installed first so that the wet trades around the window can be completed before subsequent installation of the main frame
– The main frame are installed after completion of all wet trades around the windows and hence, are subjected to lower risk of physical damages
