I live in South London and used to underestimate UV radiation, especially in summer when the sun comes out unexpectedly. A friend of mine recommended https://www.tintfit.com/shop/uv-protection, so I ordered protective film for the windows of my car and home. It turns out that it really reduces the heat in the car and preserves the color of the leather, furniture, and interior. In addition, installation was simple and safe. Now I can leave my car in the sun on weekends without worrying about overheating or damage to the materials.
