Since when does drywell hold a screw without an anchor? In this video, Matt Risinger, master builder, visits the CertainTeed booth at IPS and comes across the answer. The drywall, called Habito, can hold up to 30 lbs. on a single screw. The wall is higher density so it weighs a little more, but it offers better sound transition and you can choose to use it just in a few places in the house. It can also hold a flat screen TV and the demo has a moose head hanging with one screw. Check out the video to see it in operation, even beaten with hammers! There's no doubt it's high density and it can be used in rooms where you need that density to support what is being hung.
