Most people think of window film as a product that only performs during the summer months. 

However, 3M's All Season Window Films perform year round. Manmade heat made during the winter months will leave the building's envelope traveling through the path of least resistance - the building's glazed surfaces. Rather than simply let this heat escape through the glass, 3M's All Season Window Films reflect this manmade heat back inside the building in addition to keeping the sun's heat outside during summer. This can reduce heat loss by up to 30% to save you money and improve occupant comfort. In addition, an energy-efficient building puts less strain on your heating and cooling system to reduce maintenance and extend the life of the equipment.
