Thicker underlay will make my laminate feel more springy ?
No Laminate flooring must be fitted on a perfectly flat surface, otherwise it will feel bouncy. Another reason why your Laminate feels springy is that it has expanded and become “locked in”, it no longer fits in room where it was originally laid and is now lifting up in the centre. If your subfloor is not perfectly even using thick (6mm/quarter inch) underlay will not always solve the problem. The laminate will just be 6mm closer to the ceiling.
