🌡️ Energy Saving Window Film – High Thermal Insulation for Winter & Summer
The self-adhesive RS 220 Low-E Window Film – Dark Silver provides highly effective year-round insulation for windows exposed to intense sunlight. During winter, the Low-E coating reflects a portion of the indoor heat back into the room, helping to reduce heat loss through windows by up to 24 %. In summer, up to 80 % of solar energy is rejected, keeping interior spaces noticeably cooler.
The energy saving film is installed on the interior side of the glass and is particularly suitable for windows with prolonged sun exposure:
- 🔥 Up to 24 % less heat loss through windows in winter
- ☀️ Up to 80 % solar energy rejection in summer
- 🚫 99 % UV protection for furniture, flooring & textiles
- 🕶️ Reduces glare by up to 81% in intense sunlight
- 🛡️ Dark silver mirrored finish with enhanced daytime privacy
Key Feature: The RS 220 Low-E combines powerful solar heat protection in summer with excellent thermal insulation in winter. It is the ideal choice for rooms where maximum performance and effective glare reduction are more important than maximum daylight transmission.
☀️ Powerful Year-Round Protection for Sun-Exposed Windows
The RS 220 Low-E Dark Silver is especially suitable for large or heavily sun-exposed glazed areas. Its high solar energy rejection, excellent glare reduction and additional winter insulation improve indoor comfort in residential, commercial and public buildings. Especially on south- and southwest-facing windows, the film noticeably reduces heat build-up and glare. The lower light transmission is generally compensated by the abundant natural daylight.
🕶️ Dark Mirrored Finish & Outstanding Glare Reduction
The dark silver finish gives glazing a modern, highly reflective exterior appearance. At the same time, the energy saving film reduces annoying sunlight glare by up to 81 %, making it particularly suitable for offices, computer workstations and rooms with intense sunlight:
- 💻 Significantly less glare on monitors & displays
- 🌥️ Pleasantly dimmed indoor environment
- 👁️ Enhanced daytime privacy
- 🛡️ Highly reflective mirrored exterior appearance
- 🧽 Scratch-resistant & easy-to-clean surface
With a visible light transmission of 17 %, the RS 220 Low-E darkens interior spaces more than a light energy saving film. In return, it offers higher solar energy rejection, stronger glare reduction and improved heat retention during winter.
Privacy Notice: The mirrored effect works as long as it is brighter outside than inside. At night, with the interior lights switched on, the effect may be reversed.

Instructions: Ordering linear meters, cuttings & rolls
In just a few clicks you can decide whether you want to order linear meters, millimeter cuttings or whole rolls!
Shopping linear meters from the roll
Example: The film is available as linear meter from the roll in roll widths of 0.91 m, 1.22 m and 1.52 m. You need 2.50 linear meters from a 1.22 m wide film roll.
Step 1: Select the roll width “1.22 m” at “LINEAR METERS”.
Step 2: Enter “2.50” in the field left next to “Add to cart”.
Finally: Click on “Add to cart”. Done.
You buy 2.50 linear film meters in one piece with a width of 1.22 meters. Linear meters are cut individually from a roll and delivered as a short roll in one piece. You are billed for the linear meters ordered.
Ordering millimeter cuttingss
Please take the width and height of your window measured from rubber to rubber, minus 4 mm of leeway all around. Example: You have 2 windows sized 1.40 m wide and 2.00 m high. The correct cutting size then is 139,6 cm width x 199,6 cm height.
Step 1: Enter “139,6” at width and “199,6” at height at “CUTTINGS”.
Step 2: Enter “2” at “Add to cart”.
Finally: Click on “Add to cart”. Done.
You then buy 2 pieces of film cuttings with the desired size of 139,6 width and 199,6 cm height. The ordered film and € 5.00 for the cutting are billed.
Have whole film rolls delivered
Rolled goods (25, 31 or 50 linear meters in one piece depending on the film model) are whole film rolls. If you purchase whole rolls, you benefit from attractive volume discounts. To do this, please enter the desired numbers of roll pieces at WHOLE ROLLS. You also can send us an email to [email protected]. We will then send you an offer that you can then order. Cutting whole rolls to a specific roll width is also possible on request, please contact us.
