Construction
The shield is made of stiffened aluminum foil, so it will be resistant to weather conditions and possible mechanical damage. Sharp edges will additionally ensure easier penetration into the ground, and thus greater stability.
Extremely lightweight and space-saving, the cover at the same time is high enough to thoroughly cover the burner with a cartridge, so it will effectively protect it from the wind.
The ability to fold the shield makes it much easier to fit in a bag or backpack, and unfolding it again is extremely easy and fast.
Purpose
The Robens Windshield Foil should be unfolded in such a way that it fully covers the burner. This protects it from strong gusts of wind, which, without the shield in place, could extinguish the flame and make it impossible to prepare a meal or hot drink.
A sizable advantage of using a cover is saving fuel, which is consumed much faster during windy weather. By limiting sudden air inflows, the amount of fuel that is lost is optimized, and one container can last much longer.
