Can high winds cause composite decking to whistle?
In some situations, high winds can cause composite decking installed with clip systems to make a whistling sound. The whistle is caused by air moving rapidly under the deck, then up between the boards and across the board¹s installation clip grooves. For this reason, we recommend using Terratec Naturals Traditional deck boards in locations prone to high winds. Terratec Architectural boards can be used if steps are taken to prevent winds from flowing under the deck or through the deck boards. You can prevent wind from flowing under the deck by using solid fascia panels around the deck. You can also prevent wind from flowing up through the deck boards by using an under-deck system like DrySnap. Either approach will work.
