Foam for frostbite protection?

"Shaving cream is a good sound insulator due to the small air pockets it is made from."

I have not tried this. I am aware of foamy stuff sometimes used to suppress the pressure wave of a blast, this works because the foam is torn asunder by the blast pressure.

Can you share other applications?

Interesting idea, but gloves and a ski mask are probably more practical.

A balaclava with goggles or face shield works very well.

Looks a bit like the Kevlar hoods that firefighters use for protection from heat. The firefighter hoods probably have a larger hole to fit the SCBA breathing masks.

This might help.

Unless your foam has the same qualities needed as mentioned here, then I say no...

"To stay warm and prevent frostbite, follow these tips from dermatologists:

1. Dress in loose, light, comfortable layers. Wearing loose, light layers helps trap warm air. The first layer should be made of a synthetic material, which wicks moisture away from your body. The next layer should be insulating. Wool and fleece are good insulators and hold in more body heat than cotton. The top layer should be windproof and waterproof. A down parka and ski pants can help keep you dry and warm during outdoor activities.
2. Protect your feet and toes. To protect your feet and toes, wear two pairs of socks. The first pair, next to your skin, should be made of moisture-wicking fabric. Place a pair of wool or wool-blend socks on top of those. Your boots should also provide adequate insulation. They should be waterproof and cover your ankles. Make sure that nothing feels tight, as tight clothing increases the risk of frostbite.
3. Protect your head. To protect your ears and head, wear a heavy wool or fleece hat. If you are outside on a bitterly cold day, cover your face with a scarf or face mask. This warms the air you breathe and helps prevent frostbite on your nose and face.
4. Protect your hands. Wear insulated mittens or gloves to help protect your hands from the cold.
5. Make sure snow cannot get inside of your boots or clothing. Wet clothing increases the risk of developing frostbite. Before heading outdoors, make sure that snow cannot easily get inside of your boots or clothing. While outdoors, if you start to sweat, cut back on your activity or unzip your jacket a bit.
6. Keep yourself hydrated. Becoming dehydrated also increases the risk of developing frostbite. Even if you are not thirsty, drink at least one glass of water before you head outside, and always drink water or a sports drink before an outdoor workout. In addition, avoid alcohol, as it increases your risk for frostbite.
7. Recognize the symptoms. In order to detect frostbite early, when it’s most treatable, it’s important to recognize the symptoms. The first signs of frostbite include redness and a stinging, burning, throbbing or prickling sensation followed by numbness. If this occurs, head indoors immediately."
