Are Plywood Decorations Cheaper Than Inflatables Over a Few Years?

A sheet of plywood and an inflatable cost about the same. Which one is still in the garage in five years?

6 minute read.

Like for like, over five seasons

Prices checked 29 and 30 August 2026, electricity at 18.34 cents per kilowatt hour running six hours a night through October. The replacement row is the one carrying the uncertainty, and it is the row that decides the answer.

The honest uncertainty

Nobody can tell you how long an inflatable lasts, because it depends almost entirely on how it is treated. One that is brought in wet, stuffed into a bin with grit still on it, and put up in a windy spot may not survive two seasons. One that is dried, folded clean and sited out of the wind can go five or more.

So the table above is not a prediction. It is a way of seeing which costs are certain and which are not. The plywood column has no uncertain rows in it at all. That is the real argument, rather than any particular five year total.

Plywood does have a failure mode, and it is storage. Exterior ply left standing in a damp garage wicks water up the bottom edge and delaminates from there. Store it flat and off the floor, seal the cut edges when you build it, and that failure does not happen.

Where the inflatable genuinely wins

Size, and the speed of putting it up. A 12 ft inflatable is taller than anything you will cut from a 4 by 8 sheet without joining panels, and it goes from bin to standing in about five minutes. A plywood build is an afternoon the first time.

It also wins on movement. Animated inflatables do something, and nothing cut flat does.

And on a deep lot, where everything is read at forty feet or more, apparent size is most of the effect and an inflatable buys more of it per dollar than anything else sold. That is a real advantage and it is why the cheaper tiers of these plans use them.

The thing that actually decides it

Whether you will store it properly. That is the whole question, for both.

If decorations come down in a hurry on a wet first of November and go into the garage in whatever state they are in, the inflatable is the one that dies, and it dies faster than the arithmetic above suggests. If they are dried and packed carefully, both last a long time and the difference narrows to the twenty dollars of electricity.

A plywood build is far more forgiving of a careless pack-down, and for most people that is the honest deciding factor rather than any figure in the table.

Where this usually goes wrong

Comparing purchase prices only

They are close enough to be a tie in year one. The comparison only means anything once running cost, storage and the chance of replacement are in it.

Storing plywood upright on a concrete floor

Concrete holds moisture and the bottom edge wicks it. Flat, off the floor, with the cut edges sealed when you built it. That is the whole of plywood maintenance.

Packing an inflatable damp

It is the single biggest cause of an inflatable not coming back next year, and it always happens on the same evening: cold, wet, late, and everyone wants to be inside. Leave it in the garage to dry for a day and bag it after.
