RATIONEL FORMA

Traditional timber window

Rationel Windows in Chobham, Ascot, and surrounding areas

Catering to traditional architectural aesthetics, the Rationel FORMA window boasts an all-timber structure with delicate, non-continuous bars. Highlighting an ovolo-molded profile and slanted glazing bead, FORMA seamlessly suits vintage, classic, and rural residences. Notably, the aluminum exterior cladding showcases a distinct curved edge.

The Rationel FORMAPLUS window mirrors the frame construction of FORMA, with the sole variation being the incorporation of external aluminum cladding on the FORMAPLUS model. This addition guarantees both low maintenance demands and effortless upkeep.
