FORMA and FORMAPLUS are energy-efficient windows, which are designed for the traditional building style, for example: country houses, 2 storey houses from the 1915-1930 period, patrician villas (from the 1860-1930 period) and single storey buildings. They have rounded frames and sills, which gives them a romantic and charming look, whilst being sturdy. Whether you are about to refurbish or build new, FORMA and FORMAPLUS are the ideal choices, if you wish to have traditional farm house windows. FORMA and FORMAPLUS are just like our other windows, in that they are designed to minimize heat loss and thereby reduce the energy consumption in your home.

Our timber FORMA windows consist of a solid timber construction, inside and out. Our timber windows have a high insulation rating, long service life, are sustainable, easy to clean and maintain, whilst also having a natural and beautiful look.
Our timber/aluminium FORMAPLUS windows are produced with a solid timber construction with an external aluminium cladding. The aluminium cladding makes the window extremely resistant to wind, weather and solar degradation.
