There are numerous benefits to applying solar films on the glass surfaces of buildings. These films help retain coolness during summer and warmth in winter, while also shielding the glass to reduce overheating inside the rooms. The immediate savings in energy consumption, and consequently in utility bills, are quite significant. Additionally, solar control films provide excellent protection against UV rays, safeguarding not only our skin but also furniture, floors, sofas, and more. All this can be achieved without major renovations, exorbitant costs, or replacing windows—simply by selecting the right solar film and applying it correctly.
If you’re planning to install solar films yourself, here’s a comprehensive guide with clear step-by-step instructions to ensure you don’t make any mistakes. First, let’s go over what tools you’ll need.
To apply solar films effectively, besides having enough film rolls, you’ll need:
- A soft, clean cloth for cleaning
- A scraper for cleaning purposes
- A rubber spatula
- A spray bottle
- A metal ruler
- A metal square
- A sharp cutter with steel blade
- A spatula tool
- Paper towels
Before starting the application process, it’s essential to check that conditions are ideal. Ensure that the glass surfaces are smooth and in good condition. They should also be thoroughly cleaned. The temperature shouldn’t drop below 10 degrees Celsius, and it’s best to choose a day without strong winds to avoid dust particles getting trapped between the glass and the film.
### Preparing the Glass Surface
As mentioned earlier, cleanliness is key. Use a detergent free of residues like lanolin or wax to clean the glass. The cloth used for cleaning should not shed fibers. After a thorough cleaning, use a scraper to ensure there are no contaminants left, paying special attention to corners and edges near window frames. Now you're ready to apply the solar films!
### Step-by-Step Guide to Applying Solar Films
Let’s break down the application process into simple steps:
1. Lightly and evenly mist the cleaned glass surface using the spray bottle.
2. Lay the film down, working from the backside (keeping the liner towards you), allowing the water on the glass to hold the film in place.
3. Remove the protective liner.
4. Spray the exposed adhesive side generously with water to activate it (the water helps remove the hydro-soluble coating protecting the adhesive). After about two minutes, the adhesive will be fully active and ready for use.
5. Flip the film so the adhesive side faces the glass, spraying it again with water.
6. Adjust the position of the film, which can easily be moved around due to the water layer beneath it.
7. Begin spatulaing to smooth out the film evenly. For easier spatula movement, mix a bit of mild soap with water.
8. Trim the excess film using a ruler, square, and cutter, leaving a 2 mm gap between the film and the window frame.
9. Continue spatulaing with more pressure to perfect the application.
10. Finally, use the spatula and paper towels to firmly press down the edges.
With these steps, you’ve successfully applied solar films to your windows. Follow this method to protect all the glass surfaces in your building.
### Post-Installation Tips
It’s important to note that the adhesive on the window films takes approximately 15 days to fully dry. Avoid cleaning the windows within two weeks after installation to prevent damaging the film. By following these guidelines, you can enjoy the benefits of solar films while preserving the integrity of your windows.
