Kitchen cabinets over Pergo floors?
Pergo floors are designed to float. That is why a thin slick plastic sheet is installed underneath the flooring. It is also why there is a gap left on all sides of the floor where it meets the walls or baseboard. This arrangement permits the floor to expand and contract with temperature changes and not buckle or separate at the joints. If you place your cabinets on top of the flooring it tends to anchor that portion of the flooring and increase the chances of buckling or separation of the boards. Screwing down the cabinet makes the anchor more substantial and increases the chances of a problem.
If you are using the pergo that has a composite back then it's not good to use in a room with water. If there is a leak it can cause the floor to buckle and then you have a distorted floor that looks bad and you can't get at it if it's under the cabinets. I have made that mistake and now I have to tear one all out and replace it with tile. You spend a lot of money and then have to redo it. The only laminate floor you should put in a kitchen should be glued or nailed down for best results. Anything that floats will allow water to seep under it.
I have Pergo floors with kitchen cabinets on them. I did not install them myself, but I've experienced no problems whatsoever.
alot of time the cabinets are put on the sub floor and then the flooring just come to the face of them. then you will not have a problem. most cabinets have there own floor base in them anyway so you cannot see this. just an idea that might stop problems later.
i think of that ensure you flow with the wood. it would look quite large with the pergo floor. I quite have pergo in my eating room and lounge, yet we've not placed it interior the kitchen yet. we even have wood cabinets. my neighbor has pergo in her kitchen with wood cabinets and it sounds as though quite large.
