Also, when choosing the lawn, you need to check the roll for the presence. If the number of the latter is more than one or the size of the bald spark exceeds 10 kV. cm., Buying the lawn is not recommended. Good lawn density — 50 blades per 10 kV. cm. If you are the owner of a private or country house, then you should think about the safety of your home, and first of all about the windows. If the installation of gratings, albeit practical, but not aesthetically, then roller shutters — a way out of the situation. At the same time, prices for roller shutters are quite democratic, so everyone can afford them.
