Made from thin plastic that will warp and warp when exposed to air conditioning heat. The oval shape of the exhaust pipe creates a stress point at the bottom of the exhaust port where the plastic will warp outward (to the outside world) and the exhaust pipe can detach. I used a stack of cardboard between the vent kit and the window to keep it from warping. The heater is quite durable. I would recommend getting a softer foam from your local hardware store. Remember that using foam makes it difficult to adjust the length of the ventilation set.
