Bubble wrap is an efficient insulating material that traps air in its bubbles, which then acts as a barrier against the cold, minimizing heat loss and thus reducing heating costs. Choosing the right bubble wrap for greenhouse insulation is crucial for optimizing energy efficiency and ensuring robust plant growth. Several bubble wrap types vary in size, thickness, and material quality.

Larger bubbles can trap more air and thus provide better insulation, while a thicker wrap increases durability and insulative properties. UV-stabilized bubble wrap is often recommended, as it withstands the damaging effects of sunlight over time, avoiding brittleness and loss of clarity.

When purchasing bubble wrap for greenhouse insulation, it’s essential to consider the size, quality, and ease of installation. Some bubble wrap comes with pre-cut holes to aid in ventilation, which is necessary to avoid excess humidity and the problems that can stem from it, like mold and mildew.

The wrap must also be easy to secure in place, with options for taping or clipping to the greenhouse frames. Buyers should measure their greenhouse panels carefully before purchasing to ensure they buy enough material to cover the desired area.

Yet, while the overall performance is impressive, a minor inconvenience was its folded state upon arrival, which left some wrinkles. This didn’t affect the insulation’s efficiency but required a bit of flattening for a more aesthetic fit. Also, given its lightweight nature, I had to ensure it was securely attached to avoid any shifting, particularly around the edges and corners.

2. GSD Heavy Duty Bubble Wrap

Considering its resilience and user-friendly features, the GSD Heavy Duty Bubble Wrap is a practical solution for greenhouse insulation needs.


  • Highly durable, retains air even with minor punctures
  • Simple to inflate and customize to fit various spaces
  • Independent columns ensure partial damage doesn’t compromise overall integrity


  • Inflation requires a hand pump and can be time-consuming
  • Initial setup can be challenging until familiar with the process
  • Bulky to store before inflation, if space is limited

During my recent greenhouse update, I found GSD Heavy Duty Bubble Wrap to be an exceptional insulator. Its heavyweight design proved to be tough against the sharp edges of my greenhouse framing. I appreciated the clever design where each air pocket functioned independently; even if one got punctured, the rest kept their air and insulation properties intact.

Customizing the wrap was effortless. With perforations every 19 inches, I could tear off the amount I needed without scissors. Inflating the wrap with the provided hand pump took some effort, but I could move quickly once I got the hang of it. The clear material lets me monitor my plants without peeling back layers, a convenient feature during the colder months.

While the product is wonderful once put in place, I’d suggest setting aside some time for the initial setup. The inflation process is manual, so patience is necessary. Before inflating, the wrap was bulky and took up a significant amount of room, which was slightly inconvenient. However, once inflated and installed, the space-saving benefits became evident.

In my experience, this bubble wrap serves double duty—protecting my greenhouse inhabitants from the chill while also cushioning any items I need to ship. Its sturdy construction withstands the demands of both tasks admirably. Despite the initial learning curve and the physical effort required, I found the benefits outweighed the cons, making GSD Heavy Duty Bubble Wrap a solid choice.

3. VIECAM Air Cushion Film Roll

I believe this film is an excellent choice for protecting delicate greenhouse plants due to its durability and ease of use.


  • Provides strong and reliable insulation
  • Easy to tear off with perforation every 12 inches
  • Compatible with most air pillow machines


  • Requires a separate air-filling machine
  • Not pre-filled with air, additional setup needed
  • Limited to use with specific machine types due to hole size

Using VIECAM Air Cushion Film for insulating my greenhouse was a game-changer. The small bubbles hold air well, which creates an effective barrier against the cold. The material was surprisingly lightweight, making it easy to work with, and I could cover a large area without feeling burdened by weight.

  • The reflective surface can be blinding in direct sunlight

After using RadiantGUARD Reflex-AIR insulation this winter, I saw firsthand that the reflective surface does keep the warmth where it’s needed—amongst my tender greens and flowering plants. It was apparent that the insulation helped maintain a more uniform temperature throughout the space, which is critical during those cold snaps.

I appreciated that my heating bill didn’t hit the roof. The insulation helped my greenhouse retain heat, so my heaters didn’t have to labor as hard. This not only saves money but also extends the life of the heating equipment.

Regarding installation, I did have to be cautious not to cover any ventilation, ensuring that air could still circulate as needed. I found it a bit tricky to get it right, but a patient approach paid off in the end.

The durable construction of the Reflex-AIR was also a big win for me. It’s tough—withstanding general wear and tear better than any other bubble wrap I’ve used in the past. The enclosed air bubbles don’t pop at the slightest touch, which is reassuring over the long haul.

However, I noticed that the reflectivity could be a bit distracting on bright days. While this is beneficial for light distribution inside the greenhouse, people with light sensitivity might find the glare a bit much during installation and maintenance.

I just insulated my greenhouse using the StarBoxes Large Bubble Wrap, and it’s a game-changer for anyone looking to do the same.


  • Exceptional cushioning with large bubbles
  • Ample roll length for extensive coverage
  • Quick delivery, enhancing the overall experience

However, while handling the wrap, I did note that some bubbles are prone to popping if too much pressure is applied. While this didn’t detract from the insulating properties, it’s something to keep in mind during installation.

The price is also higher, which might be a concern if you’re insulating on a budget. Additionally, the packaging consists of two rolls, which for me was fine but might pose a storage issue for those with limited space.

In sum, StarBoxes Large Bubble Wrap is a solid choice for greenhouse insulation. It delivers on its promise of quality insulation with generous bubble size and roll length. Despite a few minor caveats, my plants are thriving, and I’m confident the bubble wrap is playing a big role in that.
