Improving Office Sustainability with Window Film

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.

How Do I Stop Freezer Doors From Fogging Up?

It’s a problem that many retailers will be all too familiar with – your glass door fridges, the ones that were specifically designed to give customers a clear view of your products, are suddenly impossible to see through.

Fogging on freezer doors is a very common problem, but one that can have a significant impact on your energy consumption, not to mention the experience of your customers. So, what exactly causes your freezer doors to fog up, and more importantly, what can you do to prevent it?

Why do freezer doors fog up?

Freezer doors fog up because of condensation, which is caused by warm, moist air coming into contact with a colder surface. In this case, the glass freezer door is far colder than the air inside your business premises, so when the air meets the glass, the moisture in the air condenses into small water droplets, which creates fog. The warmer it is inside your retail space, the faster the freezer doors will fog up and the denser it will appear.

Supermarkets and grocery stores in particular are often humid environments 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 – and the more moisture in the air, the more condensation will appear! Changing conditions both inside and outside the shop, such as changes in weather or even the air conditioning can impact the levels of condensation on the glass doors.

As you can probably guess, the condensation on freezer doors becomes a bit of a cycle. Customers open the freezer doors to get out a product, and the warm air rushes in, making it more humid in the freezer. Once they close the door and it cools down in the freezer, condensation forms – so then customers have to open the freezer doors more frequently to look inside, as they can’t see the products through the condensation.

Why is it a problem when freezer doors fog up?

Foggy freezer doors are far more than just a slight irritation to customers, they can have a real impact on a business’s energy efficiency and even profitability.

Every time a customer opens a freezer door, cold air rushes out. The more a customer has to open a freezer door, the harder your refrigeration system has to work, which can significantly drive up energy costs. Some retail freezer doors have electrical trim door heaters to keep the glass clear of fog, but over time these can be expensive, and use a surprising amount of electricity.

As well as losing money through increased energy bills, fogged doors with poor visibility can drive away customers. No matter how eye-catching or aesthetically pleasing your products are, nobody is going to pick them up if they can’t see them! It’s frustrating for customers to keep having to open freezers to search for what they need, and creates a pretty poor shopping experience. Especially if a shopper is pushed for time, they’re far more likely to buy something if they can easily find what they need.

Fogged freezer doors can also be a bit of a liability – you might find that puddles are pooling at the bottom of your freezer, meaning you’re constantly getting your employees to wipe down the doors to avoid any slips and falls.

How to prevent freezer doors from fogging

Thankfully, freezer door fogging is a fixable problem – here are a few things that you can try.

Controlling humidity in store

If your premises is prone to humidity – especially during the warmer months – consider using dehumidifiers to limit the amount of moisture that’s in the air. There is only so much that you can do to reduce humidity, as variables out of your control (such as the weather) will have an impact, but dehumidifiers might help.

Improve air circulation

Another option could be altering the layout of your shop to improve the air circulation and stop the warmer air from lingering around the freezer aisle. For example, if your freezers are close to the entrance, they could be moved to the back of the store where the temperatures are more stable – although we appreciate this isn’t a feasible option for a lot of shops.

Regular cleaning

Freezer doors can be kept more clear and dry by frequent cleaning and wiping, using anti-fog sprays if needed – although this isn’t a long-term strategy, as you might end up spending a huge amount of your time wiping down the doors in between customers!

Anti-fog film

One of the most effective ways to eliminate freezer door fog is by installing anti-fog window film. It is a thin, transparent film that can be applied to glass freezer doors to prevent condensation from forming. 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.

We offer Clarifoil® Anti-Fog Film, which creates an anti-fog coating on commercial freezer doors to help you save money and energy. In fact, Clarifoil® anti-fog window film has saved businesses over 148,881 metric tons of CO2, which equates to £68 million of savings on energy bills.

It couldn’t be easier to install – we offer professional installation services – and requires little effort to maintain.

Clarifoil® Anti-Fog Film Installation

Clarifoil® Anti-Fog film applied on the inside surface of your freezer doors prevents fogging and maintains glass transparency, so that customers can easily see the merchandise on offer.

FAQs: Does Window Film Affect Plants?

From improving air quality to reducing stress, we all know the benefits that plants can have on a workplace – and we also know that without adequate sunlight, plants can’t thrive.

So, if your workplace is fitted with window film, how will this impact your office plants?

How window film affects plants

If you cast your mind back to your school days, you’ll remember that plants rely on sunlight for photosynthesis – so if they don’t get adequate sunlight, they will start to wither. Depending on the type of window film, it will change the amount, type and quality of light that will enter a space.

UV-blocking films

Although plants need sunlight to grow, they don’t actually need UV rays. Too much UV exposure is notoriously bad for plants and people alike, with risks of overexposure including sunburn, eye damage and even skin cancer.

UV-filtering films filter out the harmful rays in direct sunlight, whilst still letting in plenty of natural light. They still let in red and blue light – red light promotes flowering, whilst blue light aids the growth of healthy leaves. So, this type of window film doesn’t tend to have a negative impact on plant growth, and can actually help to protect house plants from sunburn (yes, plants can get it too!) and excessive heat.

Reflective or solar control window film

Reflective and solar control window films reduce heat and glare by reflecting a portion of the sunlight, which can lower the levels of light that get inside. As the visible light levels are lower, this can have a negative impact on plants that need bright, direct light to thrive – such as succulents or cacti – but can actually be very beneficial for plants that love the shade and thrive without too much sunlight.

Some indoor plants – especially those with dark green leaves – fare better with window film, as it creates a more stable indoor temperature.

Frosted or decorative window film

These types of window films tend to diffuse light, which distributes it more evenly across a room. Plants tend to benefit from diffused light, as it can minimise harsh shadows and actually mimics the natural light conditions you’d expect to find outside!

Tinted window film

As you might expect, tinted window films let in less light than many other types of window film. This is bad news for plants that require a lot of natural light to grow, but great for plants like ferns or peace lilies that tend to thrive in low light conditions.

Keeping plants healthy after installing window film

If you’re worried that window film will negatively impact your plants, the most important thing you can do is select a film that balances your needs with your plants’ needs. For example, if you want to bring a bit more privacy to your workplace, frosted window film or films that block UV light can do that whilst not impacting your plants.

After your window film has been installed, make sure to keep a close eye on your plants for signs of either light deprivation or excessive exposure. Their leaves may start to yellow, or they could start wilting – monitor them to see how the light conditions might be impacting them. You can always move them closer to windows or to a more shaded area depending on how they have reacted.

FAQs: Does Privacy Window Film Work at Night?

Privacy window films are a great way to enhance privacy in both commercial and residential properties. However, their effectiveness at night depends on a few different factors.

We know how important it is for businesses to have the peace of mind that their premises are as secure as possible, especially during the darker months – here’s everything you need to know about using window film for privacy at night.

How does privacy window film work?

In the daytime, most privacy window films use their reflective surfaces to create a one-way mirror effect. This is most effective when the outside is brighter than the inside, so during the day, the sunlight reflects off the window film, making it much harder to see indoors.

Lighting conditions are the most important factor when it comes to the effectiveness of reflective films, as it’s the side of the window film that is being exposed to the brightest light that will essentially take on the privacy properties. This means that at night, if there are any lights on indoors – even if it’s not a particularly brightly lit room – the one-way effect is essentially reversed, and people will be able to see inside the property.

So, whilst reflective window films can offer some degree of privacy at night, it is dependent on the lighting conditions. Although many offices and commercial properties turn their lights off at night, there is still a chance that the interior lighting may be brighter than the outdoor lighting, depending on the external light sources.

Types of privacy window film

As well as reflective window film, there are several other types of window film available that can help to bring more privacy.

Frosted window film

Frosted window films create a translucent effect that blurs the view on both sides of the window without sacrificing natural light. Although they are probably most commonly used for bathroom windows, frosted film is also ideal for conference rooms, offices and partitions. Plus, frosted window film works just as well at night as it does during the day.

Blackout window film

Blackout window film is exactly what it sounds like, a fully opaque window film that blocks all visibility. Although this is great for privacy, blackout films don’t let in any light, so it is only really suitable for areas that require total privacy, like storage rooms.

Decorative window films

Another popular option are decorative window films, which are available in a wide range of patterns and gradients. They help to obscure the view and provide privacy but just with that bit more aesthetic appeal.

Switchable or smart films

Switchable and smart films are advanced window films that can switch from transparent to opaque at the touch of a button, using liquid crystal technology. Like traditional window films, they are applied directly to glass surfaces, but switchable and smart films are powered by electricity.

When they are in a transparent state, they let in natural light and visibility, but when they are opaque they provide total privacy. These types of films are most commonly used for spaces that need a bit more confidentiality, like conference rooms and executive offices.

How to improve privacy in your office

There may not be a window film that will totally obscure the view inside your commercial property (unless you’re willing to sacrifice all of your natural light!), but it will definitely help to improve the privacy in your workplace.

For enhanced privacy at night, window films can be combined with extra protection such as blinds or curtains. Professional installation can also make a difference to how well your window film works, as poorly fitted window film can lead to uneven coverage.If you’re looking to improve the privacy in your commercial property, we’d be happy to talk you through the best type of window film for your needs.

A Guide to Glass Manifestation Regulations

Ever noticed the patterns and graphics that are featured on glass doors, walls and windows? They’re far more than just a decorative feature – they’re actually a legal requirement. Although glass is a popular material due to its ability to let in lots of natural light and open up a space, the downside is that it’s not always easy to spot.

Manifestations were created as a way to make glass immediately apparent, to avoid any nasty collisions or accidents. These graphics are adhered to the glass to highlight that there’s something there and – hopefully – stop people from walking into them. Manifestations are required on internal or external walls, doors and windows that are made of glass.

Glass manifestation regulations

Building Regulations 2000: Part M sets out the guidelines clearly on how to make glass entrances and screens compliant to the legal requirements. It states that:

Visibility requirements: Glass entrance doors and glazed screens must have manifestations at two levels: at 850 – 1000m, and at 1400 – 1600mm above the floor. They need to contrast clearly with the background both inside and outside the glass, and should be visible in all lighting conditions.

Regulation 14 of the Workplace (Healthy, Safety and Welfare) Regulations 1992 states that transparent surfaces must be marked or incorporate features to make them visible.

Types of manifestations: Common forms of manifestations include decorative features – like continuous bands, or broken lines – or they could be logos, signs and other designs. However, they must meet the above visibility and height requirements.

However, not all glass walls, windows and partitions require manifestations, as some will already have features that make them visible enough. The legislation lists the following as exemptions:

Glazing with rails between 600 – 1500mm above the floor
Glazing that is less than 400mm in width between the frames
Single-pane glazed doors with a substantial frame
Glazed doors without frames, or with narrow frames, that have large handles or push plates on each single pane.

Benefits of glass manifestations

Legal compliance

Above everything else, glass manifestations are a legal requirement! Fitting manifestations gives you the peace of mind that your property is compliant with UK Building Regulations and the Workplace (Health, Safety, and Welfare) Regulations 1992.

Health and safety regulations

Collisions with glass are a major hazard, so it’s in a workplace’s best interests to stay on top of health and safety regulations. It’s not just about avoiding the potential legal ramifications, however – it’s about showing your commitment to the wellbeing of your employees, visitors and customers. Manifestations couldn’t be an easier way of making your existing windows safer, as they make clear glass obvious to passersby.

Design and branding

Far from just being a safety measure, glass manifestations can also be a way of further incorporating your branding into your workplace decor. Broken lines or continuous bands may be common choices, as are rows of dots of different sizes, but as long as your glass manifestation is legally compliant and is contrasting visually with the background, you can get creative. You can pick a bespoke design like company logos, graphics, shapes or patterns – for example, if you’re trying to find manifestations for a shopfront, you could go for something bold and eye-catching to draw in potential customers.

Privacy

Manifestations can also double up as extra privacy, without sacrificing natural light. If you have glass partitions separating areas that need more privacy, like board rooms or meeting rooms, frosted film can be used to keep it shielded from prying eyes, whilst also adhering to the necessary safety measures.

Glass manifestation installation

All public buildings that have glass windows need to stick to the UK safety regulations to ensure the safety of their occupants, so if your workplace doesn’t already have glass manifestations in critical locations around your building – or if you’d like to upgrade your existing ones – it’s incredibly important to get them installed.As specialists in all things glazing enhancements, we offer bespoke glass manifestations in a range of colours, designs and finishes.

All of our solutions are durable, easy to maintain, and ideal for high-traffic commercial environments, so you know they’re going to last – and they’re fitted by expert installers..
