Feal Harmo
Cold-profile aluminium sliding system – the affordable option for large glass walls

Feal Harmo is a cold-profile aluminium sliding system (no thermal break) for residential and commercial buildings where top thermal insulation is not decisive – e.g. covered terraces, summer kitchens and business premises. It is a more affordable alternative to the Termo systems, with slim profiles and a large glass area.
Key advantages
Affordable option
Cold profile without thermal break – more affordable than the Termo sliding systems.
Slim profiles
Modern, slender look and a large clear opening; sashes up to 110 kg.
Configurations
Two, three, four or six sashes on two or three tracks; with Mill 45 also for larger glass walls.
Note: Harmo has no thermal break. For heated spaces with higher insulation requirements we recommend Feal Termo 120 or Termo 150.
