Added security
without bars or shutters

Security window film

Protect your property with security window film that strengthens existing glass windows without affecting the appearance of your home or business. Our clear security film is designed to hold broken glass together, helping to reduce the risk of injury, delay forced entry and provide enhanced protection for residential properties and commercial premises.

What is security window film?

Security window film is a strong polyester window film that is applied directly to existing glazing and window glass. It is designed to improve glass safety by helping the entire pane stay together if the glass breaks. When impact occurs, the film holds broken fragments in place and reduces the risk of dangerous shards and flying glass. This makes security film a practical way to protect people, improve safety and add additional protection to your building while still allowing natural light and good visible light transmission.

Discreet protection
for homes and businesses

Traditional security measures such as bars, grilles and shutters can spoil the appearance of a property. Security window film offers a cleaner alternative. Once installed, it is virtually invisible, so you can improve safety and security without losing natural light or changing the look of your windows and glass doors. It is ideal for ground floor windows, patio doors, rear windows and other vulnerable areas where break ins or accidental breakage may be a risk.

    PR Solar have just applied their specialist film to our whole conservatory roof and doors, due to having to work from home because of Covid-19 Makes an amazing difference to the heat temperature and glare reduction in the room. So pleased to have found Paul and have this installed before Summer really kicks in. Cannot recommend highly enough.

    Friendly reliable staff, fitted the film with efficiency, professionalism, and quality is outstanding. You can really notice a difference to the heat in the conservatory. Whilst light still comes in, the heat has been reduced dramatically so no longer feels like a sauna. We are west open facing meaning sun moves around the side of the windows then above normally trapping so much heat. In 24hrs the difference is amazing! Thanks Paul!

    Very professional, Paul explained fully about the products and price, absolutely perfect fit for my windows, I am very happy with the results. We are on street level so everyone can look in when they walk past, the net curtains hid the view and light and harboured dust, it has completely changed our living room and kitchen, to be able to look out and have the light in, from the outside it looks totally natural and people cannot see inside. Would highly recommend, clean fast, superb service.

  • Paul installed window film on our bi-fold doors in our garden room, and kitchen and lounge windows. Having had skin cancer recently, I was concerned about UV and wanted to continue to enjoy our garden room without having anxiety. Skin cancers are becoming increasingly common and PR Solar Window Film is the ideal solution. It also prevents our furnishings fading! I was impressed by the installation - efficient, professional and a fantastic result! Highly recommend this service to all and everyone.

    Nice quality finish, from the outside it gives the windows a bit of shine but doesn't look over the top, it gives the appearance of looking at an empty dark room. From the inside - you can't see it! Quick service and no mess. Great, I would recommend PR Solar to anyone wanting privacy film, our new windows now look very stylish.

How security film works

Untreated glass can break into dangerous shards and broken fragments that spread quickly across the surrounding area. With security window film applied, the glass behaves differently. Instead of falling apart into loose pieces, the film helps hold shattered glass together and keeps more of the surface intact.

 

  • Helps reduce the spread of broken glass fragments
  • Helps prevent injury from flying shards
  • Provides greater resistance to impact
  • Can delay forced entry and slow attempts to gain access
  • Supports glass safety in everyday use and accidental breakage
