AirSkirts is concerned with the core of your trailer – think of wearing a vest – the system protects and insulates the main body of your trailer (or coach) and protects the most vulnerable areas where water pipes are and where the majority of heat or cold dissipates. For slide outs you’ll get insulation by the use of furniture, carpeting, and window insulation (such as Reflectix). AirSkirts will not interfere with the operation of your slides.
