Energy-saving
window film

Most of the energy your home loses will be through the windows. Energy-saving window film can help reduce this, improving heat retention by reflecting and radiating heat back into the room. It can improve insulation by up to 30% which can represent a significant saving on your energy bills.

    5 star review  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.

    5 star review  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!

    5 star review  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.

  • 5 star review  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.

    5 star review  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.

Energy Saving Window Film Diagram

What are the benefits
of energy-saving window film?

These are some of the benefits you can enjoy from energy-saving window film:

  • Better thermal performance. Energy-saving window film can increase insulation by up to 30%, keeping your home warmer in winter and cooler in summer.
  • More even insulation. Windows can lose as much as 10 times more heat than a wall. Insulated window film improves heat retention, so there are fewer noticeable cold spots.
  • Suitable for homes and businesses. These window films can be applied to residential or commercial windows to help save energy inside.
  • Significant cost savings. Energy-saving window film will help you cut your energy bills and will be much cheaper to install than new windows.
  • The same appearance. You will still have the same views from your windows – the films are transparent. Nobody would know you’ve had them applied.

Energy Saving Window Film FAQs

This is the question that many of our prospective customers ask when interested in energy saving window films. The answer is a rather straightforward “yes”. The follow-up question of “how much will I save” is a little trickier to respond to, since this will depend on a number of factors, including the type and size of windows you have, the orientation of your property, the amount of sunlight it receives, how well insulated your property is, and the efficiency of your heating and cooling systems. What we can say is that we’ve seen some property owners experience a reduction in energy costs of up to 50%. 

Many people think that there must be a catch. “I install this film and save a load of money on energy bills, but what’s the trade-off?” The truth is, there isn’t really one. The window film is extremely low maintenance after installation, requiring only light cleaning, doesn’t alter the appearance of your home or windows, and doesn’t cause excessive reflections that make it difficult to see out of your windows (a common worry). Added to all of that, if you really don’t get on with your window film, you can have it removed and your windows will not be affected at all.

There’s no doubt that window film is an investment that can pay off by cutting your energy bills down significantly. But it does still require you to part with some cash up front. So how long is it before you’re going to have to replace it? Well, it’s impossible to give you a precise answer, since there are a number of factors that will influence the rate of wear and tear they experience (local climate, conditions in the property etc), but we guarantee all of our window film for 10 years, and it often lasts much longer than that. You definitely won’t be replacing it every few years.
