Hard structure

A geodesic dome with a Tyvek(r) covering can be quite noisy, particularly in strong winds. To minimize this noise, make sure to tighten and stretch the geodesic dome to its maximum extent. The hard structure of Tyvek is also prone to shrinkage, so it is advisable to wash the dome on a gentle cycle without detergent. However, if the dome is still too stiff, consider re-covering it with a softer Tyvek type.

While converting Tyvek, the fibres must be cut through completely. Soft steel male/female rotary dies quickly dull. Hardened tool steel or tungsten carbide rotary dies are recommended for punching Tyvek(r) with a smooth surface. To prevent oversizing of blanks, side cutters with internal relief are highly recommended. Also, when cutting Tyvek(r) business forms, make sure to sever the fibres completely.

Mylar blankets

Although the noise level of a Mylar or Tyvek blanket is extremely low, they aren’t perfect. Using a Mylar or Tyvek blanket during a hurricane can result in a wake of echoes. The blankets are very lightweight, so they can’t be draped over your body like a standard blanket. They will also displace noise when you move or are moved. To protect yourself from this, you can wrap it around your head and torso, or use duct tape to sandwich it between two wool blankets.

Tyvek and Mylar blankets can be noisy when they’re new, and the cheap ones don’t have the same quality. They’re also much smaller than a tarp and won’t provide much insulation. A good tip when using Mylar is to layer it with insulation before using it as a blanket. While Mylar doesn’t provide any insulation, it can reflect body heat back to the user. If you’re concerned about noise levels, Mylar blankets can be used as a lightweight alternative to a tarp.


When choosing a waterproof material, you should consider the noise levels of Polycro and Tyvek. Both materials are noisy, but the noise levels of polycro are less than Tyvek. Polycro is cheaper than Tyvek and is also more durable. It is less noisy than Tyvek but does not breathe well. Polycro does retain moisture but if you leave it out overnight, it will collect it. If you plan to use it in the rain, you should hang it up in a sunny spot.

Many DIY backpacking gear forums warn against washing Mylar and Polycro, saying that they are too noisy. However, we tested Tyvek groundcloths with a tumble dryer and did not notice any shrinkage. DuPont’s website claims that Tyvek will not shrink below 220degF and will not melt until 275degF, although many users report minor shrinkage and noise.


Dyneema is a high molecular-weight polyethylene. Its intermolecular bonds are extra strong, making it the strongest thermoplastic. It is also a lightweight fiber that floats on water. It is strong enough to withstand the weight of an automobile without getting stuck, and its noise-reduction properties make it the ideal material for many applications.

Despite its low price, Dyneema is still much lighter than many backpacking-specific alternatives. The true lightweight solution will depend on your definition of what is lightweight and how thin you are willing to go. Some lightweight experts recommend cutting out a rough outline of your tent on a piece of groundcloth and tracing it onto the Tyvek with a sharpie. Then, cut out an inch of the Tyvek from the outline.
