Altherm horizontal sliding windows don’t project on to walkways, decks and outside areas, perfectly suited to people seeking a link between home and outdoors. Altherm sliding windows can be used where a servery is desired, for passing food and drinks outside, while removing the risk of children playing around protruding edges. Corner sliders are possible without corner posts.
