The smooth operation of Altherm™ sliding doors makes them a pleasure to open and close. They strike just the right balance between solidity and mobility.
In addition to standard sliding door formats, Altherm™ has a double slider available where two sliding panels sit within a frame and either can be moved. This gives the homeowner maximum flexibility in choice of egress or entry.
Altherm™ twin sliders go the extra distance in linking the indoors and outdoors. By opening up to two-thirds of their width twin sliding doors create a panoramic expanse.
