1800 ceiling was so easy to order from , had a great selection and the order came quickly. I order two air diverters for the office to help two freezing co-workers.. the pieces were sturdy plastic and super super easy to install.. Works like a charm.
Plastic Ceiling Corner Air Diverter
Our offices are situated in a way where vented air blows directly on the occupant, so warm air feels warmer and cold air feels colder. These helped mitigate the breeze.
