Rationel FORMA/FORMAPLUS Catalogue

Today, older and classic houses can also be refurbished to enjoy the advantages of energy efficient windows. Their FORMA range consists of all-timber windows with slim, non-continuous bars. The FORMAPLUS range is similar to the FORMA range, produced with the same solid timber construction. The only difference is that FORMAPLUS is provided with external aluminium cladding attached with clips, ensuring minimum maintenance. This product range is also ideal for new build if a classic expression is desired. FORMA and FORMAPLUS are available both with and without glazing bars. To fit in with your design, they have a variety of different glazing bars. They are easy to join in multiples and therefore suitable for complex window solutions.
