Floating Concrete Shelf Should I Glue Down Or Float My Engineered Wood Floor In My Office Addition?

Should I glue down or float my engineered wood floor in my office addition? - floating concrete shelf

I have a sun room, was taken before the purchase of the house, I will open an office. The ground beneath the concrete slab is closed. I bought the wood floor engineered to reflect the soil in the rest of the house. The mobile office has shelves and a table on the upper level are constructed from wood and is concerned that the weight can cause a problem if I install a floating wood floor. Is due to the height of the door, I have to choose between floating or glue the court.
