Amazon Window Film Cuts Room Temperature by 8°C in Heatwave
Amazon Window Film Reduces Room Temp by 8°C in Heatwave

The Rabbitgoo Heat Reflective Window Film, available on Amazon for £24.99, has been praised by customers for reducing indoor temperatures by up to eight degrees Celsius during a recent heatwave. One buyer reported that after installing the film, the bright part of their floor measured 28°C compared to 36°C before application, while the outside step reached 45°C.

How the Film Works

The reflective window film is designed to bounce heat away from windows before it enters homes, helping create a cooler indoor environment while also reducing glare and protecting furnishings from the sun. According to the brand, it blocks up to 90% of infrared and UV rays, which can help prevent fading of furniture, flooring, and soft furnishings. The film also provides a one-way mirror finish for daytime privacy, allowing occupants to see outside while making it harder for others to see in. However, curtains or blinds are recommended after dark when indoor lights are brighter than outside.

Installation and Suitability

For best results, installation requires plenty of water during application to minimise bubbles and creases, and larger windows are easier to cover with two people. The adhesive backing helps keep the film securely in place once fitted. It is suitable for smooth, flat glass surfaces around the home or office, including living rooms, bedrooms, conservatories, offices, and classrooms.

Customer Reviews

Customers have shared positive experiences. One said: "It has made a big difference! Before the film, the inside floor temperature in the sun measured at 36°C. Later, when it had all cooled down again, I installed the film. The next day at the same time the bright part of the floor was 28°C. The step outside was 45°C." Another added: "Excellent product and super easy to apply. Spray bottle recommendation is a must but took us less than 30 minutes to do the lower half of our bay window and we were delighted with the results. Still lets lots of light through and looks great." A third commented: "Excellent product, we bought this as the back of our house is south facing so it gets incredibly hot in the summer. Bought these to help reflect the sun off and so far it has helped a great deal. Would definitely recommend." Some found the film slightly tricky to apply but still effective, noting that plenty of water is key.
