That’s why we’ve handpicked our top five DIY secondary glazing kits to reduce energy bills and provide a quick and effective solution to keep your home cosy and comfortable.

What Are DIY Secondary Glazing Kits
DIY secondary glazing kits are a cheap and effective way for homeowners to improve window insulation, reduce annoying street noise, and increase energy efficiency.
With rising energy costs in the UK and an increased need for soundproofing, these kits have become popular throughout households.
DIY secondary glazing will add a layer to your existing windows, forming a barrier that supports trapping heat and reduces noise transmission.
What Are The Benefits of DIY Secondary Glazing Kits
There are many advantages to installing DIY secondary glazing kits in your home. Take a look below at some of the key benefits:
One of the main advantages of DIY secondary glazing kits is that they improve your home’s energy efficiency.
They help to prevent heat loss during the colder months (which is 8 months of the year in the UK!) and also help keep your home cool during the summer months by adding an extra layer of insulation.
All of this will result in significant energy bill savings across the year.
Another advantage is the reduction a glazing kit gives you regarding noise pollution, especially if you live in a busy area or on a main road.
DIY secondary glazing kits will add an extra barrier against outside noise, resulting in a quieter and more peaceful environment inside your home. No more barking dogs distracting you during the morning!
Secondary glazing panels can also add a layer of security to your windows, making it more difficult for intruders to enter your home through specific windows.
However, we suggest relying on something other than a glazing kit if you’re worried about security.
Historic or listed building preservation
Double glazing may be unsuitable due to preservation regulations if you live in a historic or listed structure.
In such cases, secondary glazing is an ideal alternative. It not only enhances insulation and energy efficiency but also preserves the original character and appearance of the building.
DIY secondary glazing is a practical and cost-effective solution for such homeowners.
The Top 5 Best-Rated DIY Secondary Glazing Kits
We’ve compiled a list of the top 5 best-rated DIY secondary glazing kits to help you decide when buying the right product.
Duck Indoor Shrink Film Insulation Kit
Super Easy to Install Onto Your Windows
Transparent Film to Provide Invisibility
Provides Extra Insulation and Reduces Drafts Coming Through Your Windows
Windows are a significant source of energy waste during the colder months.
We expected a complicated process and a flimsy product. Still, the Duck Indoor Shrink Film Window Kits undoubtedly exceeded our expectations and delivered well on its promises.
The initial setup required a slight learning curve, but we quickly got our head around the process when we reached the third window.
Although the film is slightly visible with edges that are less pleasing to the eye, it is an effective product for keeping the cold out, especially on draughty sash windows. However, it can only partially replace double glazing and shouldn’t be considered a long-term solution.
We’ve also noticed a considerable drop in condensation and a significant reduction in outside noise, which is fantastic.
The product in the box was very generous, providing a few extra centimetres than advertised, and the amount of tape included was more than enough.
While the roll-on method proved pretty straightforward, it did require precision to ensure the top edge was at the right angle for a straight run along the window without missing the tape.
One minor drawback is the potential waste when cutting through the folded film on the right edge, which could have been used for another window.
This product is a solid, practical solution for improved insulation and comfort. We love the Duck Brand’s other products. Still, this one was ultimately the best, and we definitely rate this as our top secondary glazing kit.
DUCK Rolled Shrink Film Window Kit
Adhesive Tape Included For Decent Attachment
Suitable For Various Window Sizes
Again, Super Easy To Install
Next on our list are the Duck-Rolled Window Kits, which we certainly recommend, especially if you have single glazing.
Working with this product during the fitting process took time as it tended to adhere to itself, making a straight-cut challenging.
However, the results are definitely worth the effort. After fitting the product, ensure a tight seal and leave it overnight. I used a hairdryer to ensure it was dry and fixed for that final touch.
The benefits are noticeable; again, there’s minimal condensation, a significant improvement in heat retention within the room we tested in, and a noticeable enhancement in sound insulation. We could barely hear the cars on the main road outside.
The film is also very discreet, although we noticed a slight haziness. This is expected when applying a product like this to your windows.
Overall, we were happy with this product and ranked it second. Once we got over the initial finicky setup, it was easy to use and looked good once finished.
Frost King Clear Indoor Shrink Window Kit
The Film is Highly Durable and Won’t Damage Easily
Suitable For All Standard Windows In Your Home
A Pack Of 9
In third position is The Frost King Clear Indoor Shrink Window Kit, and this is a worthy bronze winner.
Managing the interior windows presented no challenge when applying the product; it was a reasonably straightforward process, and using a hair dryer effectively smoothed out any ripples left, resulting in a pleasant and clear view through the glass.
The entire process of applying it to three windows took around 20 minutes overall, and we got into the flow very quickly, completing the room in just over half an hour.
The only major drawback for us is if you intend to open your windows during the warmer months of the year, which, let’s face it, everybody does, you must remove them; otherwise, as stated, sunlight and ordinary wear can cause the tape to fail over time.
Due to this, we rank this in third position. It’s a good and very straightforward bit of kit, but removing it if you want to use your window can be a significant pain.
Duck Extra Large Window/Patio Door Shrink Film Kit
Keeps Out Drafts and Cold Air Very Well
Generous Film Size
Rocking in at fourth is the Duck Window/Patio Door Kit. It’s another decent product from the Duck brand.
When purchasing this kit, you will receive an 84 x 120-inch sheet of crystal-clear plastic film and a 1/2-inch x 36-foot (432-inch) roll of double-sided tape designed to insulate one extra-large window or patio door.
The plastic film is solid, and the double-sided tape is easy to apply and remove without leaving any marks on your window or door frame.
We found it was a faff to cut to size, but eventually, we laid it down on the floor, folded it where the cut was needed, and then used a sharp blade.
Installation was easy; just double-sided tape on the edges of the window frame and using a hairdryer to finish.
This was definitely a lot more demanding to use, and it took us a long while to get a sound system in place to allow us to apply it to our windows efficiently. Otherwise, it is a good quality product.
Duck 3-Window Insulation Kit
Improves energy efficiency
Suitable for three standard-sized windows
Coming in fifth and our final recommendation is the Duck’s indoor Roll-On Window Insulation Kits.
This roll-on product is much easier than the measure, cut, and stick process we followed with the other four, where we took care to prep our surfaces carefully.
You do have to ensure your surfaces are absolutely squeaky clean, though. We used rubbing alcohol with a paper towel, and this took quite a considerable time to get right.
We put all the tape on our windows but only removed the protective top once the film rolled on the top and unfolded, which was undoubtedly a time saver.
We also ran the hair dryer over the edges and pressed the film firmly to the tape with our fingers while we were shrinking the film. The results are pretty good, and the windows look clean.
This one comes in at number five. The prep work took us a good while before applying the product. Other, easier-to-use kits are listed above, but this still works great.
Choosing the Right Glazing Panels for Your Needs
Remember when picking out your lighting panels for your DIY secondary glazing project.
You’ll want to consider what material the panels are made of, how thick they are, and what kind of glazing system you plan to use.
Look at all your options and choose the ones that work best for you and your project.
Sheet of Plastic
Plastic sheet panels are lightweight, affordable, and simple to cut to size. Depending on your requirements, they are available in 2mm, 3mm, and 4mm thicknesses.
They are ideal for do-it-yourself projects because they are easy to install with magnetic or stick-down systems.
Glass panels provide exceptional clarity and durability. They are available with single or double glazing, with double glazing providing more insulation.
Due to their weight and fragility, glass panels are typically used in screw-secured or sliding systems and may necessitate professional installation.
Acrylic panels are lightweight and shatterproof, made of Perspex or Plexiglas.
They are effective at noise reduction and insulation.
Acrylic panels come in various thicknesses and can be used with magnetic or stick-down systems.
Understanding the Different Types of DIY Secondary Glazing Systems
DIY secondary glazing kits are available in various styles, each with its features and benefits. Let’s look at the various types of DIY secondary glazing systems:
Magnetic systems rely on solid magnets to keep secondary glazing panels in place. They provide a secure fit and are simple to remove for cleaning or ventilation. Magnetic systems can be used with both plastic sheets and glass panels.
For easy access to the existing window, sliding systems allow you to move the secondary glazing panels horizontally or vertically.
They are ideal for windows that must be opened and closed regularly. Plastic sheet panels are frequently used with sliding systems.
Screw-secured systems entail screwing the secondary glazing panels to the existing window frame.
This type of system is more permanent and provides excellent security. Screw-secured systems are appropriate for glass panels and are frequently used in commercial buildings or high-security areas.
Stick-down systems attach the secondary glazing panels to the existing window frame with adhesive tapes or velcro strips.
This system is simple to install and requires no drilling or screwing. Plastic sheets or acrylic panels are frequently used with stick-down systems.
