Manufacturers of caravans and mobile homes are placing increasingly higher requirements on quality and design standards for window systems in their leisure vehicles. Polyplastic meets these wishes with a Polyvision product line, which combines attractive design and comfortable handling in an ideal manner. The lightweight aluminium frame windows - that dominate the market - are supplied fully assembled and can be easily fitted with a simple screw connection. The aluminium frame window provides the best possible aerodynamics, since the window is integrated almost seamlessly into the body of the vehicle. If so desired, the Polyvision window can also be fitted with a sun protection blind on the inside.
