We set up one of our Fortress UTV tops next to a standard plastic top in the exact same conditions. We left them in 90 degree heat for 30 minutes. When we came back out, the plastic one was warped, sagging, and extremely malleable. Naturally, our top was unwarped, and it was even strong enough to easily support the weight of a grown man.

We then checked the temperature of the bottoms of each of the tops with a electronic temperature gauge. To no surprise to us the heat baked right through the plastic top making it 138 degrees. Our tops, on the other hand, only registered at 115 degrees. This is because we attached a layer of insulation to the bottom of all of our UTV canopies. This acts as a sound deadening agent, but primarily it keeps the heat off of you during the summer, or it keeps the heat in your cab during the cold months. If your don’t think that 23 degrees is a significant amount, just stand outside when it is 77 degrees, and then stand out outside when it’s 100 degrees.
