My house has a crawl space, I have added on a room and the floor in that room is 1/8 to 1/4" lower, unfortunately. This is new construction and I am ready to lay flooring. I am using laminate. My question is can I use two layers if padding in the area that is lower, to somewhat take out the mistake in framing? This area will have little traffic as it is a room that will only be used on occasion. Thanks
