It's important to use quality underlayment to ensure the longevity of the Brava Roof Systems. The technical way to tell the difference between products is to look at the approvals and third party testing the underlayments have earned. Tarco EasyLay UDL 15 and Tarco EasyLay UDL Basic have passed rigorous testing and is Florida Approved.
The standards below are directly from the Brava installation minimum requirements. Tarco EasyLay UDL 15 and Tarco Easylay UDL Basic exceed these standards.
NOTE: Minimum requirement on a solid deck is one layer of 30 lb. To insure better performance one may choose to use a higher
performance underlayment. If you have questions regarding high performance underlayments, please call Brava Tile @ 319-
338-5706. When installing over a solid tongue and groove deck 43 lb. felt is the suggested minimum.
