As long as your purchase wooden shutters that are designed for the outdoors you will be fine. They are designed to withstand all weather conditions and you can even find ones that withstand the rain and winds of hurricanes. Just be sure that you follow instructions on how to care for them and know when you need to restain and reseal them.
You should use a solid wood that doesn't absorb water from the rain. I would recommend pine tree wood or any wood that will resist cold, heat, rain, sun, etc.
Cloud! or water
it makes it wet
Rain because rain is wet ans soaks the wood while snow being frozen is dry and does not wet the wood until after the fire is lit and it melts.
Wood (lumber).
Depending on the material and the strength of this material there may or may not be damage by rain. If it cloth covering you will be fine. If it is a wood type chair over time the wood may warp from the rain.
Paper would disintegrate in the rain because it is really thin and it can break apart real easily. In addition, its made out of wood and wood is nature. Therefore, paper would disintegrate in the rain because of its thiness and condition.
Wood is taken from rain forests, so much that today's rain forests are a fraction of their original size. Medicines can be made from chemicals in rain forest plants.
Because of factory smoke shelly wood
maybe the acid rain effect on the sea wood in the rivers
hard wood is grown in hot countries where it don't rain alot, and soft wood is grown in cold countries where it rains alot.
