Carbon window tints delivers rather better results. Carbon film doesn’t have any metal in it, so the issue with cell phones , radio transmission or wireless signals doesn’t arise when it is used. Carbon window-tinting film is about as effective as other varieties in blocking heat; its use will effectively cool inside space while also helping prevent fading to upholstery. Thus the air conditioning will not need to work so hard to cool the space during the summer, nor will the heating system be so heavily impacted during the winter. Unlike dyed film, carbon film will not fade with time.
