Most other products let you simply attach sticky tape from above to join and stabilise adjacent lengths. With SWISS KRONO Premium Sound and Superior Sound, apply sticky tape underneath to connect adjacent lengths. SWISS KRONO Basic Plus includes an overlapping flap with integrated sticky tape to facilitate installation. Unroll sheets of underlay side by side so they touch one another and join adjacent ones with sticky tape. If the underlay product you choose has an integrated vapour barrier, it should actually extend up onto the wall by about 3cm. Unlike laminate panels, there is no need to leave a gap between the underlay and walls. This is the best way to prevent lengthwise joints in the underlay and laminate from coinciding. Install sheets or boards of underlay at right angles to the laminate flooring panels. If the floor is covered by a carpet, you should remove it first before laying the laminate.
You should also keep in mind that carpeting is not a good substitute for acoustic insulation. If the differences in height are larger, other steps will need to be taken beforehand. It reaches its limit at about 3mm of unevenness per metre of floor. However, acoustic insulation is not the best choice for dealing with extremely irregular subfloors. Somewhat thicker products like 2.8mm-thick SWISS KRONO Superior Sound are of course able to compensate for somewhat greater discrepancies than thinner ones like SWISS KRONO Basic, which has a thickness of 2mm. No additional vapour barrier required (2-in-1 product)Īll SWISS KRONO acoustic underlays also compensate for minor unevenness in the substrate. For example, you can select one of four different SWISS KRONO acoustic underlays to meet your expectations and needs: There are underlays made of different materials, and they come in a wide variety of formats and thicknesses. Which one you should choose depends on your requirements and, of course, your budget. This definitely makes it a worthwhile investment.Ī large range of acoustic underlays is available. Putting down acoustic underlay when installing new laminate flooring requires only slightly more work, but yields enormous advantages.
