Bi-folding system with top-hung typology

MU2600 is a hinged folding aluminium system available with or without thermal insulation, in linear as well as curved-line design.  MU2600 is ideal for unifying spaces and is used regularly for large openings in residences and commercial buildings as well as exhibition and public spaces. 

MU2600 is comprised of two systems: 

  • MU2600 Thermal 
  • MU2600 Slim Thermal
  • MU2600 
Technical Features & Solutions
  • The system offers multiple design solutions and covers all possible frame configurations such as single or even sash numbers, with or without doors and opening inward or outward. System MU2600 is constructed to open fully for maximum utilization of views, merging the inside and outside. 
  • MU2600 Thermal is available in straight or curved lined design and MU2600 is available in curved line design. 
  • High security is achieved with multiple locking points and high-tech precision accessories. A variety of high quality handles, embedded handles and mechanism are available from MUSKITA, Giesse Italy and G-U Germany. 
  • Smooth rolling of sashes is achieved with a ceiling sliding mechanism (top-hung typology) and the rollers that can withstand a maximum weight of up to 100 kg per sash.
  • Excellent air and water tightness is ensured by specialized sealing EPDM gaskets and the system’s accessories. 
  • MU2600 Thermal achieves high thermal efficiency through the 20 mm wide polyamides that thermally break the profiles, contributing to excellent energy savings.
