Palusol® and Palusol® SW

Palusol® – The innovative solution for intelligent fire protection

Palusol® and Palusol® SW are intumescent materials used  for passive fire protection that effectively extend the fire resistance duration of building components.

Due to its high-quality standards, Palusol® has been the market leader in the field of intumescent silicate sheets for over 50 years. These fire protection sheets are widely used in passive fire protection in both public and private buildings. In the event of a fire, a Palusol® silicate sheet quickly foams up (= intumesces) under the effect of heat whilst exerting inflation pressure. The resulting non-combustible, heat-insulating and pressure-resistant foam prevents the spread of fire and smoke to other rooms by selectively filling joints and gaps in the immediate vicinity. In this way, Palusol® buys important time until the arrival of the fire brigade and thus contributes not only to protecting lives but also to preserving the value of material assets.

Our team conducts research and development in close cooperation with fire protection experts and customers to further improve the material properties and expand our product range. Thus, innovative solutions such as the Palusol® SW sandwich product range are constantly being further developed.

The core of Palusol® fire protection sheets consists of water-containing silicate reinforced with glass fibers protected on both sides by a layer of epoxy resin against the influence of weathering. Palusol® sheets, which are manufactured in various thicknesses and dimensions, can be converted into strips or smaller sheets and used in a wide variety of passive fire protection applications.

Palusol® SW sandwich boards have been specially developed for the manufacture of fire doors made primarily of wood materials and for use in fire protection walls. The different arrangements of high-density fiberboard (HDF) and Palusol® fire protection sheets achieve high component rigidity and fire resistance ratings of up to 90 minutes.
