Affordable Durable Effective Heat Blocking Window Film
We all love and need the sun, but homeowners know that sunlight is the enemy of energy efficiency. With sunlight streaming in the windows all afternoon, temperatures inside the house can rise by 10-20 degrees and more. This puts an enormous strain on the HVAC system and results in greater energy use and higher energy bills. Heat blocking window film from PR Solar can put an end to that sad state of affairs and let you spend your hard-earned money on other things.
What Is a Heat Blocking Window Film?
PR Solar provide heat blocking window film as well as heat reflective window film that can make it easy to maintain a stable, energy-efficient interior. These window films can be applied to domestic or commercial glass surfaces with equal effectiveness, helping you save money while enhancing the appearance of your glass.

How it Works
Heat blocking window film is applied directly to the inside panes of your exterior facing windows. There they block UV rays and reflect heat that would otherwise pass through untreated windows. At the same time, these amazing films act as a kind of insulation keeping the existing heated or cooled air inside where it belongs.
Because our heat-blocking window films can block out up to 3/4 of the heat that would normally come through your windows you’ll no longer need to keep opening and closing drapes and blinds to try and maintain a stable temperature inside your home or office. Keep in mind too that heat-blocking window film is not some trendy, flash-in-the-pan product that will come peeling off your windows in 6 months. Our heat-blocking window films can last 15-20 years, in some cases longer.
These are some of the reasons why people choose us:

After sweltering inside our house during the most recent heatwave, I made the decision to install window film on all our South-facing windows. I contacted PR Solar Window Film Ltd and they responded promptly to my request and gave me a call to chat through options. On the day of installation, after assessing all the windows, we decided to switch to a different film that would better suit our needs. Paul did the installation with care and we're happy everything. What really stood out for us was Paul being more than happy to return on a different day to complete installation due to us waiting for a glass pane to be replaced. Thanks Paul and the PR Solar Window Film team!
