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'.
Did you know that honey isnât the only thing that bees make? Bees also produce a compound called propolis from the sap on needle-leaved trees or evergreens. When they combine the sap with their own discharges and beeswax, they create a sticky, greenish-brown product that is used as a coating to build their hives. This is propolis.
