Minimalist Sliding Door Series
We designed FORMA120 as a minimalist sliding door for warm climates, also suitable for indoor areas where performance matters. Panels reach up to 3.5 m high, the four-sided frame can be fully concealed, and the visible mullion is only 19.8 mm wide. The internal groove of the overlap edge can be reinforced with stainless steel for high-wind areas.

We state two different maximum fixed-panel figures for this series: general product information gives fixed panels up to 8 m², while the specification diagram for each glass option gives a maximum of 4 m² for an opening sash and 6 m² for a fixed panel. Both figures are shown here rather than one being assumed.
Dimensions and weights are as specified by FORMA and should be verified against final project or shop-drawing requirements before use in any quotation or specification.
