The good news: Normally, you don't have to pay too much attention to the material of your walls when installing with frame anchors, because frame plugs can be universally installed in a variety of materials. Walls made of concrete, brick, hollow concrete blocks, aerated concrete, plus much more are all suitable. Since you don't have to search for special fastening solutions for each building material, frame plugs save you time.
