How does Tekton Building Wrap compare to HYDRA Wall Underlay or HYDRA Classic?
All three are flexible synthetic wall underlays that act as a secondary weather-resistant barrier behind the cladding. All three are suitable behind brick veneer, and all three are suitable in extra high wind zones when installed over a rigid air barrier.
The main difference is the cladding each can sit behind. Tekton is a non-absorbent underlay, so non-absorbent claddings must be installed over a drained cavity. HYDRA Wall Underlay and HYDRA Classic are absorbent underlays. They can be used behind both absorbent and non-absorbent claddings, in direct fix and cavity applications.
