Plastic Sheds: The Basics

Let’s quickly answer some questions about plastic sheds, so we all know what we’re on about moving forward.

Depending on what they’re made from, you might also hear plastic sheds referred to as:


  • Resin sheds
  • Vinyl sheds
  • High-density polyethylene sheds

Plastic sheds are usually made of vinyl (also known as polyvinyl chloride or PVC) or high-density polyethylene (HDPE). These are synthetic polymers that are durable and UV-resistant yet, light and easy to move.


Vinyl plastic sheds are built for tough outdoor use and are weather-resistant whilst remaining strong.

Plastic sheds aren’t designed for customisation. Attempting to paint a plastic shed will probably result in paint not binding and isn’t a viable solution. 


The good news is that plastic sheds retain their colour even if left out in harsh sunlight, so there should be little need to paint your plastic shed.

Plastic sheds are easy to assemble. Most panels snap together and, with you and a friend following the assembly instructions, you can have your plastic shed put together in no time.


Hopefully, now we’re all on the same page as to what plastic sheds are. With that checked off, we can move on to the pros and cons of owning a plastic shed.

Due to the nature of their construction and materials, plastic sheds are also highly weather-resistant. 

This is true of both hot and cold climates. HDPE and PVC vinyl plastic has been developed to withstand weather extremes. This is especially useful in countries like ours where we can experience four seasons in a day!

Plastic sheds are also resistant to:

  • Sunrays (as they’re UV-resistant)
  • Snow and water which won’t permeate your shed roof (unlike in timber sheds)
  • Rain and wind
  • Heat and cold

No longer are the days when plastic sheds are made of plastic that goes brittle in the cold and sags in the heat. These days, plastic sheds are the forerunner in year-round durability.

Are plastic sheds waterproof?

Plastic sheds as a whole are weatherproof, made from waterproof panels. Plastic sheds are sure to keep your tools dry due to their weather-resistant material and tight joints.

Are plastic sheds fireproof?

No. Despite being made from fire retardant materials, all plastic will eventually become combustible if exposed to fire.

The materials used in plastic sheds these days are not only weatherproof. They also make for a sturdier, more durable outdoor garden building. 

Not only can plastic sheds stick around for longer, resin no longer fades as fast. Thick plastic panelling also provides your shed’s contents with insulation. This, in turn, helps to regulate your shed’s temperature and prevent damp.

How strong are plastic sheds?

HDPE and PVC plastic shed panels are strong and durable. They are weather-resistant and make for a sturdy construction. For extra strength, you can always opt for a BillyOh Newport Lean To Plastic Shed Light Grey With Floor

One question we always get asked about plastic sheds is whether or not they can stand up to the wind.


And, whilst we’ve heard folktales of the skies filled with plastic sheds that have blown away, it’s not true. Granted, some weaker plastic sheds could get knocked over or even broken apart in strong weather conditions.


But modern HDPE plastic vinyl sheds with reinforced steel frames, like the easy-to-assemble BillyOh storage shed, you’ll have it built before this ever occurs. Plus, you can always leave panels in the shade until you’re ready to install them.

However, unlike wood, even this won’t cause rot and further problems.


And speaking of wooden garden sheds…

Are Plastic Sheds Better Than Wood?

As with the idea of ‘good’, ‘better’ will depend on your wants and needs.

But to look at some quick takeaways:

Are plastic sheds better than metal?

A metal shed might provide good levels of security, but walls can easily become dented. You will also have to treat your shed against rust and install vents or insulate it. This will also help to stop condensation in metal sheds.

Still, let’s look at some quick takeaways:
