Questions & Answers

I have a walk out patio, sunlight comes in and hits an area I'd like to use to place some collectibles such as legos and arcade machines and am concerned about yellowing of the plastic and artwork. Will this prevent this?

Answer This Question

The S2M blocks about 99% of UV, so it would help reduce the effects of ultraviolet, such as fading on furnishings. The S2M is a clear film with no tint, so it is not for reducing light or heat. We have tinted films that can help reduce these as well as UV.

    I have skin that’s extremely sensitive to the sun will this be as effective if not more effective than spf sunscreen on the skin?

    Answer This Question

    The S2M would block about 99% of UV; it is most effective for up to 380nm wavelength (transition from UV to visible light occurs at 480nm). This would help provide protection from UV, although we do not know the effectiveness in comparison to sunscreen.

      Will leaving the backing sheet attached create any problems? I'm going to install this in a flat frame horizontally under a domed skylight. The sheet will be supported only at the edges.

      Answer This Question

      The adhesive underneath the backing liner would provide UV protection, although we would not know how the UV would affect the backing layer and its appearance if the backing liner remains there to be exposed to the UV.

        Is this film UV400 rated
        ByApr 28, 2026
        1 Answer | 
        Answer This Question

        The S2M blocks about 99% of UV overall; the UV rejection is most effective up to about 380nm wavelength. The amount of UV that goes through increases as the wavelength approaches 400nm. (Beyond 400nm is visible light; the S2M is a clear film with no tint, so most of light goes through.)

          Is this safe to apply onto a skylight?
          ByApr 19, 2026
          1 Answer | 
          Answer This Question

          The film can be installed if it is a flat, smooth surface. A curved surface requires heat-shrinking the film; only professional tinters should attempt this. Note that the S2M is intended for the interior side.

            Does it give any privacy looking in

            Answer This Question

            This is a clear film with no tint, so it is not for privacy purposes.

              Im still confused. So do you mean to say it covers everything 100nm to 380nm? I just want to clarify which ranges we're talking about.
              ByApr 16, 2026
              1 Answer | 
              Answer This Question

              The film blocks about 99% of UV throughout the wavelength range of approximately 280nm to 380nm, which covers UVB and most of UVA. Note that UVC from the sun is blocked by the atmosphere.

              By|Apr 17, 2026


                Hi I'm just a bit confused? So does this window film block the range from 0nm - 380 nm, or everything above 380nm? Thank you for your help.
                ByApr 14, 2026
                1 Answer | 
                Answer This Question

                The UV spectrum is divided into UVC (100nm to 280nm wavelength range), UVB (280nm to 315 nm), and UVA (315nm to 400nm). The UV blocking effect of S2M is most effective up to about 380nm wavelength, so the optimal performance range of the S2M film covers UVB and most of UVA. (Visible light starts at 400nm, and the S2M allows most of visible light through since it is clear.)

                  I guess it works
                  I bought this to prevent heat loss and condensation on my windows. In the picture, the window on the left has the film and the one on the right doesn't. They were left overnight, and I took the picture at about 9:00 am. The side with the film still has condensation, but the beads of water are much smaller than the other. Presumably, there's less condensation because the window with the film isn't as cold. I can't comment on it's efficacy at blocking UV radiation as I don't have a way to measure.

                    Only 68% UV Protection
                    The description reads 99% UV protection, but using a UV tester, results show only 68% UV protection. You can get up to 92% by applying two layers, but the product still does not meet the amount of protection promised. This was a waste of $50 for me, unfortunately. I am extremely disappointed.

                      It really works! I installed this product about a year ago. We have a great view, so we went with clear instead of a darker tint film. Hard to know if it really did work, blocking UV rays, reducing heat, etc. Just recently our AC wasnt working right. The inside temp would get up over 80 degrees, even though the thermostat was set at 73. While we were waiting to get it fixed, we decided to put sheets over the windows to see if that would help. We have a wall of 10 floor to ceiling windows, and we get direct sunlight during the morning. The sheets had no effect on the heat. It was just as hot with the sheets blocking the sunlight as without the sheets. For me, this was evidence that the film was actually doing its job.

                        This is more transparent than I thought it would be! Virtually zero color when applied. The instructions were legible, thorough, and helpful. Best option at this price point.

                        It was easy to install. I think it will block the suns fading rays. I hope. Thanks

                        “Decorative” is not what I was needing. What a waste of time installing, removing, and paying for something that provided no value
