How Foggy Freezer Doors Can Impact Sales

The average shopper spends 37 minutes in the supermarket per visit. This might sound leisurely, but when factoring in the amount of time it takes to peruse each aisle, search for specific products, queue at the tills and put away their shopping, it doesn’t leave much time for browsing.

Having merchandise clearly on display is crucial, as consumers just don’t have time to be rifling through the shelves. Freezer doors that easily fog after being opened by shoppers are a real problem for retailers, as they obscure the view inside the cabinet, and can take a significant amount of time to clear again. If the freezer doors in your commercial premises are prone to fogging, it could be taking a hit on your sales.

Why do freezer doors fog?

When a freezer door is opened, the warm air from inside the shop enters and mixes with the cooler air inside the freezer. The temperature difference between the two causes the moisture in the air to form water droplets on the door, which scatter the light and create a foggy appearance.

The reason why it’s such a problem in supermarkets and grocery stores is because the constant flow of customers means the atmosphere is more humid – and the more moisture in the air, the more fog will appear. If the doors are constantly being opened and closed, the condensation will continue to build up.

How do foggy doors impact sales?

With so many time-pushed shoppers, many simply just don’t have time to wait around for the freezer doors to clear, or to keep opening doors to see what’s in each freezer. If they can’t see what they need at a glance, they are liable to walk away and not make a purchase.

Another major factor is that not being able to see products can reduce the amount of impulse purchases made. A study showed that 88% of British consumers make at least one impulse purchase a month, with almost half of these (45%) being made at a supermarket. If your customers can’t easily see your products, they are far less likely to make an impulse purchase. Considering that the average person spends £50.43 a month on impulse purchases, this can really add up, which directly affects your revenue.

Foggy doors can also be a negative signal to shoppers regarding the maintenance of the store. They might assume that a seal in the door is broken, and question the safety of the products in the freezer – or even just generally get the impression that the store is poorly maintained. Perception of your premises and products matter, so making the effort to keep a store looking its best is key.

How does anti-fog film stop freezer doors from fogging?

One of the most effective ways to prevent freezer doors from fogging is by installing anti-fog film, like Clarifoil®. As condensation is caused by the interaction between warm air and a cold surface, anti-fog film is designed to counteract this. Anti-fog film contains hydrophilic properties, which means that it attracts water. A hydrophilic surface will actually cause the water molecules to spread more evenly across the surface, rather than grouping together as water droplets, which means that the glass will remain clear.

The anti-fog film also changes the surface energy of the freezer door. As hydrophilic coatings attract water, the film contains anti-fog additives that reduce surface tension, which means the moisture to form a thin, transparent layer. Some films absorb small amounts of moisture, which is released back into the air once the temperature and humidity is more stable. This means that a freezer door that is constantly being opened and closed can stay clear.

Unlike other methods of clearing fog – like heated doors – anti-fog film is a passive energy saving option that doesn’t need any energy consumption at all – so not only is it better for the environment, but it incurs significant cost savings over time. Anti-fog film is extremely durable and gets to work straight away, so there is no downtime. It’s easy to maintain, as it is designed to be durable, resistant to scratching and can be cleaned using standard products.

OVAGLAS Update February 2026

February has been another productive month across our UK and international projects. Throughout the month, our installation teams delivered specialist window film installation, glazing enhancement, and retrofit window film solutions across retail, commercial, and public-sector environments. From privacy window film and solar control window film to safety film upgrades and printed graphics, these projects demonstrate the versatility and performance of modern glazing enhancement systems.

Across offices, residential buildings, transport hubs, and shared workspaces, we installed tailored window film solutions to meet specific site requirements. In each case, we focused on improving energy efficiency, enhancing privacy, increasing safety compliance, and elevating interior branding. As a result, this varied portfolio reinforces our expertise in supplying and installing high-performance window film throughout the UK and internationally.

To conclude the month, we attended EuroShop in Düsseldorf, where we connected with industry partners and explored the latest developments in retail design and efficiency.

Below is a summary of the glazing and retrofit projects completed over the past few weeks.

To begin, we installed an Opal frost privacy band in a fully glazed office workspace in Oxfordshire. We aimed to introduce meeting room privacy while maintaining natural light and an open-plan feel. After conducting a detailed site survey, we applied a continuous Opal frost manifestation band at eye level. This approach improved privacy and ensured glass safety compliance. Overall, we delivered a clean, contemporary finish that balanced discretion with design.

Shortly afterwards, we visited a shared office space in Newcastle. There, we installed frosted window film alongside bespoke company branding on glass partitions. While the client prioritised privacy, they also wanted to retain the bright, open atmosphere typical of co-working environments. Therefore, we applied a crisp frosted manifestation band and overlaid precision-cut, full-colour branding. This solution enhanced privacy while creating a bold visual statement.

Next, we moved into the hospitality sector. At a hotel and spa, we installed Opal frost film to a glazed entrance doorway. In this setting, operators must balance privacy with presentation. For this reason, we applied high-quality Opal frost vinyl to the central glass panel. This installation created a uniform finish, enhanced discretion, and improved glass visibility for safety compliance. The final result complements the calm, premium atmosphere of the space.

We then shifted from privacy to performance in Oxford. In this residential project, we installed Silver 20 solar control window film in apartment hallways. Large glazed corridors allowed significant heat gain and glare. To resolve this issue, we fitted the film to the internal face of the windows. Silver 20 reduces solar heat, minimises glare, and improves energy efficiency without significantly darkening the space. Consequently, residents now experience a more comfortable hallway environment alongside a cleaner external appearance.

As part of the ongoing revamp of a companies London HQ, we delivered a comprehensive package of internal branding and graphics installations. A large-format wall graphic transformed a plain wall into a striking focal point. In addition, we installed window films, internal signage, and further branded elements throughout the building. Together, these installations created a cohesive and professional fit-out that strengthened brand presence and enhanced the workspace.

Later in the month, we completed a high-level installation of printed gradient window film at Banbury Train Station. Because of the scale and height of the glazed entrance elevations, we used specialist access equipment and carefully coordinated the works. The printed gradient film creates a smooth fade effect across the glass. It enhances privacy inside while maintaining natural daylight. Externally, the station now presents a clean, contemporary appearance, and internally passengers benefit from improved comfort and discretion.

We also carried out a safety film strip and replace project at a Battersea apartment. Over time, the existing window film deteriorated and affected both performance and appearance. We removed the aged safety film, prepared the glazing, and installed a new high-performance safety window film that meets current standards. This upgrade restored clarity, improved glass retention, and enhanced protection without compromising the London views. The project demonstrates why property managers should proactively replace ageing safety window film to maintain compliance and long-term performance.

Finally, we closed the month at EuroShop, the world’s largest retail trade fair. In partnership with Kenfield Ltd and Aerofoil-energy, we presented integrated retrofit solutions for the retail sector. Through collaboration, we showed how combined technologies improve in-store performance and energy efficiency. Altogether, EuroShop provided a strong conclusion to a busy and productive month.

Improving Office Sustainability with Window Film

As we are all becoming increasingly aware of our impact on the planet, more and more businesses are looking for ways to reduce their carbon footprint – after all, buildings and offices account for almost 40% of all global energy-related carbon dioxide emissions.

The largest share of a workplace’s carbon emissions comes from electricity, accounting for between 30-40%, with a significant amount coming from heating and air conditioning.

If your business is looking to implement new green initiatives and find ways to be kinder to the planet, a great step is installing window film. Window films are an effective and eco-friendly way to increase energy efficiency whilst reducing energy consumption and the environmental impact of your business.

Why use eco-friendly window film?

It might not seem like a big change, but you might be surprised at how much difference installing window film can make to the sustainability of your business.

Better energy efficiency

Of course, the main benefit of using window film is that it can actually reduce your carbon footprint. UK summers are getting warmer and as for the rest of the year, we know that cold snaps aren’t just a winter thing. As a result, many businesses will be relying on air conditioning and heating throughout the year.

Solar window film is very effective at reducing heat loss or gain to regulate indoor temperatures. When it’s warm outside, energy-saving window film minimises the amount of heat that is coming into the building by blocking or absorbing solar energy. In the colder months, window film helps to retain interior heat, meaning that you can use your central heating less to keep the workplace a comfortable temperature.

As using window film means less reliance on air conditioning or heating, it helps with your overall energy consumption, which leads to a lower carbon footprint. In large commercial premises, this is particularly beneficial, as energy costs can be substantial.

Plus, window films are designed to still let in natural light. On sunny days, the glare reduction properties of window film means that your employees can enjoy the daylight without irritating screen glare, and won’t need to use artificial lighting.

Of course, as well as the benefits for the planet, using energy-efficient window films does lead to cost savings in the long term as your business will be using less energy. These savings could even be reinvested into further sustainability measures.

Better sun protection

If you notice that your office furniture isn’t looking as vibrant as it used to, UV rays are likely the culprit. Over time, the harmful UV rays will damage, fade and discolour furnishings and equipment that is exposed to sunlight. Materials such as wood, leather and textiles are all at risk, and darker and more vibrant colours tend to fade faster.

Every year, 1.2 million desks and 1.8 million office chairs are sent to landfill – we’d bet that many of these are still in a useable state, but just look a bit past their best. Using window film can block out the rays that cause furniture damage, meaning that your office furniture will last longer, reducing the need to replace them prematurely. Less waste and less resource consumption will always have a positive impact on the planet!

Avoid replacing windows

If you’re looking to upgrade your windows, adding film to your current windows is a far more sustainable choice than completely replacing them.

Installing window film negates the need to remove and dispose of your existing windows, which cuts down on the amount of waste that will be sent to landfill. Window manufacturing can be bad for the environment, as many types of windows use a significant amount of energy to produce, and the production process emits harmful pollutants and greenhouse gases.

Benefits of sustainability initiatives

There are many advantages of green initiatives for a business. Naturally, the cost-saving benefits are a key advantage, but there are more positives! Being a more sustainable business can improve your image – showing a genuine interest in the environment is very appealing to both stakeholders and customers. It can also help you work your way to certain certifications that can boost the business’s corporate image, and can even help when applying for certain funding if you can show your commitment to the planet.

Protecting Your Interiors From Sun Damage

Whilst natural daylight may be very welcome in a commercial property, it can have one very noticeable side effect. Fading furnishings – such as furniture, floorings and upholstery – unfortunately go hand in hand with sun exposure. This is a particularly big issue for modern buildings such as office blocks, as floor-to-ceiling windows that let in a lot of light are incredibly popular.

Fading interiors can be frustrating, as it can be expensive to replace or repair them. Although nothing short of blocking all light sources will totally stop your furniture from fading in the sun, thankfully there are ways to minimise it.

What causes furniture to fade in the sun?

Although some types of rays are more harmful than others, the whole solar spectrum is actually to blame for fading furnishings!

If you notice your furnishings are looking like they have been bleached by the sun, the main culprit behind it is ultraviolet (UV) radiation. UV light causes dyes and pigments to break down in materials such as fabrics, leather and wood, and even paint. Over time, this leads to a loss of colour, hence the ‘bleached’ look.

As well as UV light, visible light – the light that we can see – is also part of the problem. Prolonged exposure to sunlight can also contribute to fabric fading, as the intensity of the sunlight can also break down colour pigmentation.

The heat from the sunlight also plays its part – if you think back to your science lessons, you might remember that higher temperatures can increase the rate of chemical reactions. This speeds up the fading process, meaning the coloured pigments can break down even faster.

Plus, the speed at which the materials fade depends on the type. Items made from natural fibres such as cotton and wool typically fade faster than synthetic fibres, whilst wood and leather can dry out in the sun, leading to colour loss. Fabrics that are dyed with low-quality dyes also degrade faster in sunlight, as they don’t tend to be UV-stable.

It’s worth noting that it’s not just sunny days that can fade your furnishings either – UV rays are present even on overcast, cloudy days, so your furniture is at risk of damage all throughout the year.

How to stop your furnishings from fading

Thankfully there are ways to keep furnishings in good shape that don’t just involve storing them in a windowless room – here’s how to minimise the impact of sunlight on your furniture.

Rearrange the room

On a sunny day – ideally when the sun is at its highest – take note of what the sun hits in a room to see what could be most vulnerable to fading, and move it to a more shaded area of the room. Prioritise pieces that are made of natural materials, as these are more vulnerable to sunlight.

This method can help in rooms with smaller windows, or rooms that don’t tend to get flooded with light, but otherwise it can be tricky to find spots that aren’t affected by sunlight. This can be especially difficult in rooms such as offices or boardrooms, where the furniture takes up the majority of the floor space. It also won’t help to protect floorboards or carpets from sun damage.

Pick your colours wisely

As we know, darker colours absorb more light, whilst lighter colours reflect more light. Because of this, light colours will fade more slowly and also lose pigmentation less obviously, so they tend to look better for longer.

If you have a room that gets a lot of natural light, consider picking furnishings, paint and floorings in a lighter colour to allow for this – although, of course, this will limit your design choices, especially if you need to stick to brand colours for your interiors.

Install solar window film

As the saying goes, prevention is better than cure! The easiest and most convenient solution is to stop the harmful rays coming in in the first place. Unlike curtains and blinds, window film doesn’t stop light getting in, or block the view – it just filters out the rays that cause issues.

Window Film to Prevent Fading

Although window film can’t totally stop your furnishings from fading, as visible light and heat can still come in through your windows, window film is still the most effective way to reduce it. It can stop up to 99% of all UV light, which can not only reduce damage from sunlight, but can also stop irritating glare and also save money on energy bills.

Solar control window film – also known as UV protection window film – can be installed on existing windows, blocking out potentially harmful UV rays whilst still letting in natural visible light and warmth, and without obstructing your view.

Solar window film works as anti-fade window film by reflecting or absorbing certain wavelengths of sunlight before it has a chance to penetrate the glass. It allows visible light to pass through, but unwanted wavelengths like UV are rejected. In cooler months, window film works to conserve warmth, as a significant amount of heat is lost through windows.

Professionally Installed Anti-Fade Window Film

Some things are better left to the professionals, and installing window film is definitely one of them. Having correctly installed window film means that you will be able to enjoy all of the benefits it comes with it for longer. The OVAGLAS team has worked on projects of all scopes and sizes, so there is no job too big or complex for us. To find out more about our solar window film, get in touch with the team.

How Window Film Can Improve Your Workplace

When it comes to thinking of ways to improve your workplace, upgrading your windows might not even be on your radar, but office window film can actually make a world of difference. From improving privacy to increasing energy efficiency, you’d be surprised at the impact installing window film can make for your business.

We’ve outlined the most popular types of window film and how they can lead to an even better working environment.

Privacy Window Film

Privacy window film can be applied to both interior and exterior windows, depending on the type that you choose. Interior window film is typically applied to areas of an office or commercial building where extra privacy is needed, such as boardrooms, conference rooms and individual offices. You can buy tinted or frosted film to obscure the view into the room, whilst still allowing plenty of natural light in.

There are even window films such as Casper Cloaking Technology, which are specifically designed to help obscure LED/OLED screens from prying eyes, allowing businesses to keep confidential data private and avoid data breaches.

If your commercial property is located in a busy area, or an area with a large amount of traffic, using privacy film can prevent people from seeing inside the premises without sacrificing natural light or the view. It adds not just privacy, but also added security, as privacy film – especially if it’s tinted or reflective – can act as a burglary deterrent.

Energy-Saving Window Film

Energy saving window film is an incredibly popular choice for commercial properties, and for good reason. Applying window film can help to regulate indoor temperatures throughout the year, by reducing solar heat during summer and helping to retain heat during the winter. As well as creating a more comfortable working environment, applying solar control window film can reduce energy bills and energy consumption, as there is less need to rely on heating systems.

Applying solar window film won’t just reduce heat, it can help to block harmful UV rays. UV is one of the contributing factors to the fading of furniture and upholstery, which can be costly to replace, and its harmful rays can also contribute to skin damage. Energy-saving window film is a cost-effective and quick way to prevent this without blocking out natural light.

Additionally, applying window film can minimise irritating glare on computer screens and other reflective surfaces, which can improve comfort for employees and lead to increased productivity.

Blast Glass Containment Film

Blast glass containment film is designed to reinforce glass in the event of an explosion or accidental shattering. It works by holding the shattered glass in place to minimise the risk of injury or damage from shards of broken glass. Glass containment film can be installed on its own or alongside a retention system, which can further anchor the film and glass in the window frame.

Although bomb blast film can be used anywhere, it’s an excellent option for businesses where the risk of targeted attacks is higher, such as banks, financial institutions, or government buildings. It can drastically improve the safety of your building, providing peace of mind to you and your employees.

Safety Window Film

Similarly to bomb blast or security window film, safety window film ensures that in the event of a breakage, the glass will do so in a safe and controlled way. Glass is commonly used in commercial properties, but as it is a fragile material, it is at risk of accidental damage.

Safety film is a fast and convenient way to strengthen glass and reduce the chance of it shattering, potentially causing injury or damage to your property. It helps glass to better withstand the force of impact from not just accidents, but from other unexpected incidents like natural disasters, or even break-ins.

Windows can be the weak points of a building, providing easier access to would-be burglars, but window film can make it harder to break in. It can also add more time to forced entry attempts, which can give security personnel more time to respond in an emergency.

Window Film for Offices and Commercial Premises

Although each type of window film offers distinct benefits, there are also some additional benefits across all types of film. All of them will make some reduction to your company’s energy consumption, which will save money but also contribute to the overall eco-friendliness of the building, which is great if you are participating in a green building initiative.

Window films are also a far cheaper and easier alternative to replacing your windows, saving your business time and money. Plus, as many window films are available in a wide range of colours and patterns, you’ll be able to choose a film that suits your branding or interior design.

FAQs: How Does Anti-Fog Film Work?

Fridge and freezer door fogging is a problem that has plagued retailers for years. As consumers open and close doors, fog can quickly build up on the inside of the glass. Not only does it negatively impact the customer experiences, but businesses can find that it pushes up their energy consumption and electricity bills.

However, applying an anti-fog coating inside the doors can quickly and effectively solve this problem – but how exactly does it work?

Why do freezer doors fog up?

Condensation causes freezer doors to fog up, as the warm, moist air comes into contact with a colder surface. As a glass freezer door is colder than the air in a shop or business premises, when the warmer air meets the cold glass, the temperature difference causes the moisture in the air to condense into water droplets. These water droplets scatter light, creating a foggy appearance. The warmer a space is, the quicker the freezer doors will fog up, and the denser it appears.

Supermarkets and grocery stores in particular tend to be humid as there’s a constant flow of customers coming in and out of the shop, as well as refrigerated products that release moisture into the air. The more moisture in the air, the more fog will appear. Environmental factors like changes in weather or air conditioning can impact the levels of condensation on the glass doors.

How does anti-fog film stop freezer doors from fogging?

As condensation is caused by the interaction between warm air and a cold surface, anti-fog film is designed to change this behaviour. Anti-fog film is hydrophilic, which means that it attracts water. Whilst this might sound like the opposite of what you need, a hydrophilic surface will actually cause the water molecules to spread more evenly across the surface, rather than grouping together as water droplets. As there aren’t any fog droplets to scatter light, the glass will remain see-through.

The anti-fog film also works to change the surface energy of the freezer door. As hydrophilic coatings love water, the film contains anti-fog additives that reduce surface tension, which essentially causes the moisture to form a thin, transparent layer. Some types of film can absorb small amounts of moisture, which is released back into the air once the temperature and humidity is more stable. This means that a freezer door that is constantly being opened and closed can stay clear.

It’s worth remembering that anti-fog film doesn’t get rid of moisture entirely, and it won’t stop ice from forming in particularly low temperatures, but when it is installed and maintained properly, anti-fog coating is a very effective option for commercial freezers and fridges.

Why is it important to prevent fridge and freezer doors from fogging?

Aside from being irritating for customers who can’t see any of the products on display, foggy fridge and freezer doors can be a real financial drain. Some supermarkets and shops rely on door heaters that are fitted around the door frame to keep the glass clear, but these can be very expensive to run.

Each time a freezer door is opened, the cold air rushes to escape. In a busy shop where freezer doors are opened countless times a day, the refrigeration system has to work even harder to maintain its temperature. We know that electricity costs are a major overhead for business owners, and we are all more conscious than ever of how much energy we are using. Research has shown that in supermarkets and other types of food shops, refrigeration consumes around 30-50% of the total energy of the site, with shops that primarily sell frozen food at the top of that range.

Plus, not only are electricity bills higher, but foggy doors with poor visibility can drive away customers. If products aren’t immediately obvious to passing consumers, there’s a higher chance they will walk straight past. Shoppers that are pushed for time are far more likely to make a purchase if they can easily find what they are looking for, so retailers could easily lose out on a significant number of sales.

Installing anti-fog film

Installing film with anti-fog properties is a simple and effective way for retailers to prevent their glass surfaces from fogging. Especially when compared to costly heating systems, applying an anti fog treatment to freezer and fridge doors will incur significant cost savings over time. Unlike using heated doors, a film with anti-fog properties is a passive energy-saving option that doesn’t require any energy consumption at all.

When installed correctly, anti-fog film is extremely durable and gets to work straight away, meaning there is no downtime. It’s also easy to maintain, as it is designed to be durable, resistant to scratching and can be cleaned using standard products.
