Our 'energy-contributing' Rationel FORMA windows offer the same excellent properties as Rationel FORMAPLUS, but these windows are made entirely from timber. The angled glazing bead and ovolo moulded profile make it an ideal choice for country-style and traditional designs. Rationel FORMA ensures that high levels of daylight and solar heat gain are achieved. This free heat is the best energy source available and also provides a healthy and comfortable indoor climate. These windows come with security ironmongery as standard, and are suitable for Passiv Haus buildings.
