All American Rolling Shutters completely block out all light when closed. They can be used to keep out light when sleeping, or eliminate glare when watching television. Sun control may be the biggest benefit of rolling shutters in Colorado due to the intense sunlight and UV ratings. When closed, rolling shutters block out all of the sun's light, and Colorado's intense UV rays and most of the heat. As energy costs rise, the savings can be substantial.
Everything there is to know about propolis. Propolis is a 100% natural, antimicrobial substance made from plant resins, which is collected by honeybees (Apis mellifera) along with the nectar and pollen they need for food. It is also known as 'bee glue' and sometimes as 'hive dross'.
The composition of propolis can vary depending on the location of the bees and what trees and flowers they have access to. For example, propolis from Europe wonât have the same chemical makeup as propolis from Brazil. This can make it difficult for researchers to come to general conclusions about its health benefits.
