Unlock sustainability and reduce your carbon footprint: Save energy and costs with window films.

Did you know that windows account for over 30% of your building’s heating and cooling load? That’s nearly 30 times less insulating than your walls or roof. For Building Managers facing mounting pressure to reduce their energy consumption, this presents a real challenge.


As building regulations continue to evolve towards greater thermal efficiency, managers have two choices: invest in costly window replacements or opt for a cost-effective solution to enhance their existing windows.

Energy-saving window film offers a practical, eco-friendly solution by:

  • Reducing solar heat gain during the Summer 
  • Minimising heat loss during the Winter
  • Reducing solar glare and fading
  • Trimming energy consumption
  • Saving you up to 15%  on energy costs annually 
  • Providing your building with privacy and security
With window film, your commercial buildings will enjoy stable temperatures year-round, leading to lower energy bills.

What is Low E Insulation Window Film?

Low E Insulation Window Film goes the extra mile in battling extreme weather. Just like solar control films, they function similarly to keep the elements where they belong every season. What sets them apart, however, is their remarkable efficiency against cold weather.

✔️ These films are a lot more powerful at retaining heat during the winter (while still keeping cool air in during the summer).

✔️ These films boast a patented design that reflects heat back into the building, erasing those chilly drafts near windows.

✔️ These films upgrade your windows at a fraction of the cost of replacing them.

Now, let’s dive deeper into how window films, retrofitted to glass, serve as an effective and proven solution to combat climate change in homes and workplaces.

Environmental Product Declaration (EPD)

An EPD provides valuable insights into a product’s environmental impact throughout its lifecycle, enabling informed choices.

Our 3M™ Sun Control Window Film Prestige Series is EPD-registered, signifying that we’ve optimised the production of these films with minimal environmental impact.

Transparency is key, and you can explore the full EPD here.

We don’t just promise energy cost reduction; 3M measure the ecological footprint of their film production, ensuring it’s no worse than comparable products.

Energy Performance Certficate (EPC)

Energy performance matters in today’s energy-conscious world. And the good news is, that window film application can boost a building’s EPC rating, often paying for itself in under five years. 

Since April 1, 2018, retrofitting inefficient windows with window film has become a great option to meet Minimum Energy Efficiency Standards for both domestic and non-domestic properties. Why? Because a law was introduced at this time preventing non-domestic properties from being let unless they comply with the regulations.

For Landlords, this means they need to ensure their properties comply with Minimum Energy Efficiency Standards, and window films are the most cost-effective way of improving their energy efficiency rating.

BREEAM & LEED Certifications

BREEAM (Building Research Establishment Environmental Assessment Methodology) and LEED (Leadership in Energy and Environmental Design) are globally recognised benchmarks indicating that a building has a certain level of environmentally-conscious design.

Why is this important to you?


As part of the government’s Construction Strategy, it is now a requirement for all public projects to undergo an environmental assessment.

How can we help you achieve these certifications?


Our LLumar high-performance window film supports the attainment of various BREEAM credits, improving thermal and operational energy performance, alongside occupant well-being and productivity.

Such credits are available through the use of window films under the following categories: Energy, Health & Wellbeing, Materials & Waste.


Prioritise sustainability: embrace window films to reduce your carbon footprint, cut energy costs, and play your part in a greener, more efficient future.
