The In’Flector ‘Breeze’ see-through window insulator has exactly the same properties as the In’Flector but has been designed to allow the material to breathe. In certain circumstances, it may be necessary to allow ventilation from the window into the room. The In’Flector ‘Breeze’ enables ventilation to occur through the In’Flector material, without compromising the effectiveness of the radiant heat barrier.
