Maximising Energy Savings: The Advantages of Installing Window Film This Winter

As the temperatures plummet during the frosty winter months in the UK, the cost of heating commercial spaces and homes escalates. The relentless surge in energy prices adds to the financial strain. Fortunately, an effective and affordable solution is now within reach – window films.

A. Introduction to Window Films

Window films, particularly Low-E (Low-emissivity) films, can enhance the energy efficiency of your building while providing an array of additional benefits.

1. What are Window Films?

Window films are thin coatings applied to the surface of windows. They are designed to minimise heat transfer, thereby contributing to improved energy efficiency. These films contain microscopic layers of metal or metallic oxide that reflect heat while permitting light to pass through.

2. The Role of Window Films in Energy Efficiency

By reflecting heat back to its source, window films can drastically reduce your energy costs. They help maintain a consistent, comfortable temperature throughout your building, minimising hot and cold spots. In the summer, they reflect sunlight and heat outside, while in the winter, they reflect heat back inside.

B. The Advantages of Window Films

Aside from energy efficiency, window films offer several other advantages.

1. Comfort Enhancement

Window films can significantly improve comfort within a building. They help maintain a stable, comfortable temperature throughout your space, reducing hot and cold spots.

2. UV Protection

The films can block up to 99% of the sun’s harmful UV rays, protecting occupants’ skin and preventing furnishings and flooring from fading.

3. Cost-Effectiveness

While the initial cost of window films might be higher than other window treatment options, they are less expensive and disruptive than full window replacements.

4. Versatility

Window films can be applied to existing windows, offering a cost-effective solution for businesses and homeowners looking to improve their energy efficiency without the expense and disruption of replacing windows.

C. Low-E Films Versus Window Insulation

Both Low-E films and window insulation aim to enhance energy efficiency. However, they function in different ways and each has its own advantages.

1. Window Insulation

Window insulation works by creating an airtight seal, reducing drafts and preventing cold air from entering or warm air from escaping.

2. Low-E Films

On the other hand, Low-E films focus on controlling radiant heat transfer, making them particularly effective in buildings located in hot climates or those with large, sun-facing windows.

D. Installation of Low-E Window Films

While there are many types of DIY window films available, Low-E window films often require professional installation due to their specific fitting requirements.

1. Measuring the Window

Accurate measurements are key to achieving the perfect fit.

2. Cleaning the Window

Any dirt or dust can interfere with the film’s adhesion. Therefore, the window should be thoroughly cleaned before application.

3. Cutting and Applying the Film

The film should be cut slightly larger than your window size. Spray the window with a wetting solution, remove the backing and apply the film to the glass.

4. Smoothing Out Bubbles

Use a squeegee to remove any bubbles, working from the centre outward.

5. Trimming Excess Film

With a sharp knife, carefully trim the edges for a perfect fit.

E. Maintenance of Low-E Window Films

Maintaining your Low-E films is straightforward. Cleaning can be done with standard glass cleaning products and a soft cloth or squeegee. Avoid any abrasive materials that could scratch the film.

F. Maximising the Energy Efficiency of Your Windows

Apart from installing Low-E films, there are other measures you can take to maximise the energy efficiency of your windows. Inspect the seals around the frame, both inside and out, and replace any old or degraded caulk. Consider adding weather stripping to the exterior of your windows and installing storm windows for an extra layer of protection during the winter months.

G. The Impact of Window Films on Energy Consumption

Research indicates that window films can have a significant impact on a building’s energy consumption. They can result in lower energy consumption in heating, cooling, and even lighting.

1. Energy Savings in Heating

By reflecting the longwave infrared radiation from a space back inside, Low-E coatings significantly reduce heat loss, making them favourable for areas where heating load is dominant.

2. Energy Savings in Cooling

Low-E films can also reduce heat gain through a reduction in solar transmittance. This characteristic can be favourable in cooling dominant climates.

H. Window Films Versus Blinds

When comparing the investment in window films against blinds, several factors come into play. Window films offer energy savings, improved comfort, UV protection, and can enhance the aesthetic appeal of your building. In comparison, while blinds can provide some level of light control and can add to the decor, they do not offer the same level of energy efficiency or UV protection.

I. The Role of Window Films in Reducing Carbon Footprint

By reducing the energy consumption of a building, window films can help to reduce its carbon footprint. This can contribute to the UK government’s goal of an 80% reduction in greenhouse gas emissions by 2050.

J. Choosing the Right Window Film for Your Business

When selecting a window film for your business, consider factors such as the film’s energy efficiency, UV protection, aesthetic appeal, and cost. It’s also important to consider the specific needs of your building, including its orientation, window size, and climate.

To conclude, installing window films can be an effective and affordable way to improve the energy efficiency of your building. They offer a range of benefits including comfort enhancement, UV protection, cost-effectiveness, and versatility. Whether you are a business owner looking to reduce energy costs, or a homeowner seeking to enhance comfort and energy efficiency, window films can be an excellent investment.

By incorporating window films into your energy-saving strategy, you can enjoy a warmer, more comfortable space this winter while saving on your energy bills. So why wait? Make the smart move today and invest in window films for your building.
