On the other hand, if the board is made thicker, the load on the floor surface to be insulated increases. The depth of the recess is preferably up to one third of the thickness of the board. Thus, the present invention was able to provide a sound insulation floor structure having high sound insulation performance and having a balance of strength, weight and price. The foamed polyethylene mat used in the sound insulation floor structure of the present invention has a thickness of 1.
There is no limit to the number of metal laths with mortar of 5 to 3 mm, but it is usually preferable to set the number to 1 to 5.
