If you’ve ever struggled with too much heat, glare or fading furniture due to sunlight streaming through your windows, solar window film could be the perfect solution for you. It’s simple and easy to use but extremely effective in keeping your home or office comfortable – and it can help to cut down on energy bills.
But how exactly does solar window film work, and how do you apply or remove it? Let’s take a look at solar film for windows and how to use it.
What is solar window film?
Solar window film is a thin, adhesive film applied directly to glass surfaces to help regulate heat, reduce glare and block harmful UV rays. It comes in a variety of shades and finishes, meaning you can choose a film that best suits your needs – whether that’s keeping a conservatory cool, adding privacy or improving energy efficiency.
Unlike blinds or curtains, solar window film lets natural light into a room while keeping your space protected. At Purlfrost, we offer a wide selection of films designed to tackle different issues, from heat control to privacy solutions.
How does solar window film work?
Solar window film is made up of multiple layers, including a UV-blocking coating and a heat-reducing layer. When applied to a window, it works by reflecting and absorbing solar energy before it enters your space.
Some films have a mirrored or tinted finish to enhance their ability to block heat and glare, helping keep rooms cooler in the summer and reducing the need for air conditioning. Not only does this make your space more comfortable, but it can also lead to energy savings over time.
The benefits of solar window film
Solar window film comes with plenty of benefits for your home or office. Here are some of the reasons our customers choose to use solar window film:
- They reduce indoor temperatures – The film blocks a significant amount of solar radiation, helping to keep rooms cooler. This is especially useful in conservatories or spaces with large windows that tend to overheat.
- They minimise glare – If you’ve ever struggled to see your TV or computer screen on a bright day, you’ll know how frustrating excessive glare can be. Solar window film reduces glare, making it easier to work, watch TV or relax without squinting.
- They provide UV protection – Prolonged exposure to UV rays can cause furniture, carpets, and artwork to fade over time. Solar window film blocks up to 99% of these harmful rays, keeping your interiors looking fresh for longer.
- They enhance privacy – Some films have a reflective or tinted finish, making it harder for people to see in during the day while still allowing you to enjoy natural light. This makes solar window film a great option for homes, offices and even shopfronts.
- They’re cost-effective and easy to install – This window film is an affordable alternative to expensive window replacements. With a simple application process, you can enhance the comfort of your space without the need for major renovations.
- They’re versatile – Solar window film can be used in a number of spaces such as bedrooms, offices and bathrooms. You can even opt for conservatory solar window film to aid in keeping temperatures cooler in those hotter months.
How to apply solar window film
Applying solar window film is easier than you might think, and you don’t need to be a DIY expert to get it right. Just follow these simple steps:
- Clean the glass thoroughly – Use a lint-free cloth and soapy water to remove any dust, dirt, or grease. This will ensure the film adheres smoothly.
- Measure and cut the film – Cut the film slightly larger than the window to allow for adjustments.
- Spray the glass with soapy water – This helps prevent the film from sticking too quickly, allowing you to position it correctly.
- Peel off the backing – Carefully remove the protective layer from the film.
- Apply the film to the window – Place the adhesive side against the glass and slide it into position.
- Smooth out air bubbles – Use a squeegee to remove excess water and any trapped air bubbles.
- Trim excess film – Use a sharp blade to cut away any overhanging edges for a clean finish.

How to remove solar film from windows
If you ever need to remove your window film—maybe to replace it with a different style or because it’s been on for several years—it’s just as easy as applying it. Here’s how to do it:
- Lift a corner of the film – Use a razor blade or your fingernail to get under one edge.
- Peel slowly and evenly – Pull the film away from the glass in a steady motion to avoid leaving too much residue behind.
- Use heat if necessary – If the film is stubborn, a hairdryer can help loosen the adhesive.
- Remove adhesive residue – Spray a soapy water solution or an adhesive remover onto the glass and gently scrub with a sponge.
- Clean the glass – Wipe down the window with a lint-free cloth to remove any final streaks.
