The main ingredient of all our products is stone wool, made from natural rock such as diabase and dolomite. Using a special method, the stone is melted and spun into fibres, which are then pressed, shaped and cut into ceiling panels. Stone wool is an inorganic material that is resistant to attack by vermin, bacteria, mildew and fungi. It is also non-flammable and is therefore used for fire insulation and similar purposes. It is thermally stable to temperatures in excess of 1,000ºC, which is the temperature reached after around two hours on the standard fire curve. The front and back faces are covered with a layer of various types of glass fibre, while the edges are coated with a water-based paint.

These treatments improve the handling characteristics of the panels and their environmental stability. The panels are cut with a water saw to minimise wastage and dust. Paints and adhesives that are used in production are water-based. Parafon ceiling panels are supplied in cardboard boxes, shrink-wrapped on to pallets.
