Why is carpeting unsuitable as a sub-floor for laminate?
Carpeting is not a suitable sub-floor for laying laminate flooring and must be removed before laying the laminate. The carpet located under the laminate causes a springing movement when the laminate surface is walked on and this causes excessive pressure in the edge area. This destroys the tongue and groove connection and causes an open joint to form. The carpeting must also be removed for reasons of hygiene (formation of mould or mildew, development of odours). The sub-floor must be absolutely level, dry, clean and firm.
