Our mesh lightweight, mesh strips available in black or grey come as standard with weighted bottoms to ensure they don’t flap around in the wind. These are stylish mesh covers are designed to aid open kitchens and food production environments that desperately need fresh air circulating. The mesh strips allow hands-free access through doorways and remove the hassle of health and safety concerns that come with flies, insects and bugs buzzing around and contaminating food produce.

Our fly screens and insect curtains are used extensively in hot, busy, environments like in commercial kitchens, restaurants, bakeries, and cafes. Workspaces that generate a lot of heat, which is only made worse during the hot summer months. Fly screens and insect barriers work exceptionally well in these environments as they allow the workers to keep doors open, but due to the small holes in the mesh strip, there’s a steady stream of air passing through. These holes aren’t large enough to allow pests to pass through which promotes a hygienic work environment without having to sacrifice the comfort of the workers.

Product Focus: PVC Chiller Blinds

pvc chiller blinds

On hot days, customers want to walk into newsagents, shops, bars, cafés or restaurants, go straight to your fridges and pick out a cold drink, sandwich, salad or snack. Imagine the disappointment for your customers that when they finally choose their product, it’s warm and in unsatisfactory condition. Did you know that up to 40% of customers just don’t buy warm drinks or food items? They’d rather go without or worse, go next door to your competitors!

This poses you with a problem – how do you display your goods, keep your energy consumption down and showcase your product offerings in multi-deck chillers whilst keeping your products cold?  The answer is simple: install an inexpensive PVC chiller blind.  The PVC is crystal clear so your customer can see into the fridge, the PVC strips are lightweight enough for your customers to simply reach through and grab the cold product they desire – you get to keep all your customers happy and save a fortune in energy in the process.


YES!  The ROI is extremely fast, typically you will save up to 50% on fridge energy consumption, and they will pay for themselves within a few months. They optimise airflow evenly within the cabinet ensuring you have minimum product wastage. They also extend the life of your retail unit by lessening the load on the compressor.


Yes! They are extremely easy to self-install, maintain and clean. Our clever support system allows the full curtain section to clip in and out which also ensures you can restock your fridges with ease.  They do also help to deter petty theft – it’s not as easy to slip items into pockets when there is a PVC chiller blind in the way!


Colour: Clear / transparent (light blue tint)
PVC profile: Flat

Anti-Insect Protection | Preventing Bugs In Your Workplace

Anti-Insect Protection

Does your business require anti-insect protection? It can be a struggle working in hot, busy environments. Especially with the increased temperature and annoying bugs flying around, this results in a lot of distractions and irritations that make the working day that little more difficult than it needs to be… That’s where we come in! 


We understand that businesses struggle where hygiene and contamination issues need to be taken into consideration. Which is why we manufacture and supply a range of PVC to help make your working days a little more bearable in the summer months. 

Perforated PVC:
When working in hot environments during summer, it can often be a necessity to keep doors and windows open, however, this invites unwanted pests into your working environment and in workplaces such as food preparation areas, the utmost care should be taken concerning health and safety. Flies or other airborne pests can cause contamination by simply landing on work surfaces, causing bacteria including salmonella, typhoid and cholera to be spread, which can cause detrimental harm in certain working environments. If this sounds like an issue you have… Our perforated PVC is ideal for you! The strips are clear, much like our standard PVC door kit but with small perforations throughout the strip which are large enough to allow a breeze through but small enough to block any airborne pests from passing through.

Anti-Insect PVC:
If your main issue is reducing the number of pests that enter your workplace, our anti-insect PVC is perfect for you… This product is bright yellow, a colour that is known for repelling flies and insects. This feature is key in ensuring your environment is protected from pests that may cause harm in your workplace and will ensure that you can keep doorways open to avoid your workers overheating this summer. 

Mesh Fly Screens:
All our grey and black fly screen mesh strips require minimum effort to install. We offer a variety of suspension systems: The bullet system is a pre-punched snap on and off, this system is quick to install and is perfect for pedestrian health and safety requirements as there are no separate steel parts. The insect barrier is also extremely durable. If heavy pedestrian use is expected, the product will withstand it. The snap-on system also means that insect curtain can be maintained with ease – simply remove the strips and clean individually (with warm water only).

Our range is available with a variety of suspension systems designed to suit you. If you would like to discuss your requirements with our sales team, we can offer a full bespoke quotation designed to remove all your summer problems. Contact our team on 01925 638753 or email 

Energy Saving Solutions For Small Businesses

Energy saving solutions

Energy prices are climbing and showing no sign of slowing down, but what energy saving solutions can you apply to your workplace?

Making simple energy saving changes to improve your efficiency can save you money, plus it’s good for the planet too!

On brighter days, switching lights off and allowing natural light in will avoid any wasted energy. This may seem like a small thing to do but if implemented enough throughout the week or month, you’ll notice the difference!

Offices constantly have appliances running throughout the day, from PC’s, desk fans, radios and printers – it’s easy to see how energy bills are sky high! It’s often a necessity that these items are switched on, however, it can be very costly. If your workplace makes a conscious effort to switch appliances off when not in use, you’ll be surprised at the energy savings you can make.

It also makes a huge impact switching to energy saving light bulbs where possible, for example, changing tube lights to T5 energy efficient lighting saved £2,282 on the annual energy bill and 8.52 tonnes of CO2 emissions.’.

Companies are introducing measures wherever possible to keep energy bills low, whilst maintaining a reputable carbon footprint and a “green” image. To counterbalance energy price increases we must try to prevent heat loss in industrial and commercial environments.  There are two ways to do this: Insulate and then protect.

Insulation is a primary factor in relation to heat loss and must be looked into extensively.  Insulate your roofs, wall panels, offices and access points to ensure heat is retained wherever possible.  To achieve maximum efficiencies however we should also consider introducing PVC strip curtains in areas of high footfall/traffic as a means of protection against energy loss.  Internal and External Doors that are constantly open to allow traffic and pedestrians access, will cost you greatly, as the cold air enters the building and the warm air escapes or vice versa the air-conditioned cool air escapes and the hot external environment enters.

The simplest solution to this expensive problem is to install PVC strip curtains which allow easy, hands-free access through openings, they return to their original position rapidly and create a substantial barrier between internal and external areas.  Case studies have shown that energy bills can be reduced by up to 60% if installed correctly.

Considering that an average PVC Strip Curtains cost less to purchase and install than your average monthly energy bill, and will pay for themselves usually within 3 months, it makes sense to speak to the specialists at PVC-Strip, invest a small amount in an economical product, that in the long run will save you money and improve both your carbon footprint and green image.

Simplifying PVC Specs

Are you clueless on PVC Strip and unsure on how the technical specifications will affect your application? We simplify the specs and help you discover your ideal curtain…

Temperature Range:

PVC strippvc strip temperature management has a large temperature range for such a flexible product.  The temperature range is simply the range at which the PVC strip will maintain its structure.  At temperatures lower than specified the molecules will react together becoming hard, brittle and the clarity will alter.  At the higher end of the spectrum, the material will deform, lose its shape, and basically melt. Here’s our guide to the minimum and maximum usage temperatures on quality PVC strip:

Standard Grade PVC: -15°C – +50°C
Low Temperature / Polar Grade PVC: +30°C – -40°C  

Chemical Resistance

pvc strip chemical resistanceWe are often asked, “is flexible PVC strip chemical resistant?” The answer is a resounding yes!  PVC strip has good mechanical properties and excellent chemical resistance, as with other general-purpose plastics.  It’s particularly good with organic solvents, salts, acids, and alkalis. This is why it’s used to make chemical storage tanks, plastic valves and flanges, drainage, and water pipes.  However, if you want to understand how it behaves in relation to a specific chemical within a given environment then it needs to be independently tested.

We can send you samples to test in your actual environment or for more technical results we can send our materials to independent Laboratories on your behalf.  Bear in mind independently testing is costly and the customer bears the cost for any external test requirements but it will ensure that you’ve got bespoke, application-specific test results for your unique environment.

Tensile Strength

tensile strength pvc stripSo, you have a flexible PVC strip technical specification in front of you, you know that you need a strong material but you have no idea what that means or what to look for in quality grade PVC.  Here we break it down into simple terms and explain the basics of tensile strength.

The tensile strength of a material is measured in N/mm². This is the maximum force the PVC strip can be subjected to before it breaks. Good quality PVC strip should achieve results between 10 and 18 (the stronger the PVC the higher the number).

  • Standard grades should be around 16-17;
  • Low-temperature grades should be around 12-13;
  • Super polar grades should be around 10;

Low-temperature grades include added softeners in the PVC compound mix to avoid the material becoming brittle at freezing temperatures, hence the lower figures.

Heat distortion

pvc strip heat distortionTo simplify what is actually quite a complex test, the Vicat softening temperature or heat distortion temperature is basically how far a needle can penetrate into flexible PVC strip, to a specific depth at given temperature variables. The higher the temperature the easier it is for the needle to penetrate the PVC strip.

PVC strip is at a disadvantage when it comes to having a low heat distortion level if you compare it to other plastics, however, this is due to its high levels of flexibility and requirements to be a soft, moveable material.

Ideally, you want this score to be between 45-50, the higher the score the more rigid the material will be.

Fire Retardant

pvc strip Fire retardantPVC strip is an inherently fire resistant plastic as it contains a high percentage of chlorine.  Make no mistake, all PVC will burn (as do almost all materials) but when burned, hydrogen chloride gas is released which slows down the continuous combustion reaction and when the naked flame is removed it will self-extinguish – the material basically chokes itself.  Additionally, the odour released is unpleasant allowing early detection of a fire.

There are many ways of evaluating flexible PVC strip, all PVC strip should be as minimum classified as “self-extinguishing” but the oxygen index is a good line in the sand – the higher the value the better.  Materials that achieve OI ratings of 26+ are as near to a true fire retardant PVC material as you’re going to get in the PVC world.

If would like to view our independent testing video showing the behaviour of standard grade and OI27 PVC strip where you can see which PVC takes the flame and burns quicker for yourselves – then please just ask and we can send it over to you via email.

European Usage of Plastic Strip Curtains

Agricultural plastic strip curtains

In the UK alone, plastic strip curtains are installed in a wide variety of industries such as cold stores, cleanrooms, warehouses, and schools. But where are the most common applications worldwide and why are they such a popular product?

As plastic strip curtains are such a diverse product, there is a huge range of applications PVC strip can be installed in. In the UK, they are most commonly found in very industrial settings, such as warehouses and cold stores. Plastic strip curtains are also found in environments such as zoos, schools, and restaurants – so the products are diverse enough to be applied almost anywhere… They even feature in movies and tv on occasion!

But what is the difference in Europe? Countries have unique applications where strip curtains are a necessity for example. France and Italy are known for their impressive vineyards and wine production but strip curtains are an essential asset to their production, as they ensure the cellar keeps at the perfect temperature whilst still in development. 

Spain and Portugal:

Known for their food markets and fishing ports, open-air stalls, food and hot weather means it’s the best place for bugs to gather – this is where PVC strip curtains come in… By installing strip curtains where possible on market stalls and fishing ports, it means the food cannot be contaminated by flies and other pests but also with the added benefit of keeping the food at a regulated temperature.

Norway & Germany:

Data centres are dotted all around Europe, most commonly in Norway & Germany. Some of the larger companies, like Digiplex who are based in Norway & Sweden, are the innovative leaders in the Nordic region. Plastic strip curtains are used in data centres to help with optimising server cooling, to aid in reducing carbon emissions and work as a low-cost non-technical alternative to expensive server cooling systems.
