Beautiful pergola! The Louvers make all the difference  definitely provide more shade. They’re very easy to adjust  it so nice having the option to adjust them throughout the day! We hired an experienced company to set it up for us  it did take them a little less than 2 days to finish. In addition, it is necessary to purchase wood from your local hardware store to install inside of the posts. We also had them footed for a sturdier build. We’ve had it up for about 6 months now  it’s holding up well  easy to clean. Highly recommend this over the standard pergola  definitely worth the extra  for the louvers!
