ACOUSTIC UNDERLAYS BENEATH LAMINATE FLOORING
Placing acoustic underlay underneath laminate flooring greatly enhances your living comfort, as it noticeably reduces reflected walking noise within your home. If you live in an upstairs flat, your neighbours below will also appreciate not hearing every step you take through the ceiling (transmitted impact sound). For these reasons alone, acoustic insulation is a very important addition. But that’s not all – it delivers other benefits as well:
- Extra thermal insulation
- Compensation for unevenness in the floor
Putting down acoustic underlay when installing new laminate flooring requires only slightly more work, but yields enormous advantages. This definitely makes it a worthwhile investment.
Kinds of Acoustic Underlay
A large range of acoustic underlays is available. Which one you should choose depends on your requirements and, of course, your budget. There are underlays made of different materials, and they come in a wide variety of formats and thicknesses. For example, you can select one of four different SWISS KRONO acoustic underlays to meet your expectations and needs:
BASIC PLUS

A useful enhanced version of the SWISS KRONO Basic insulating underlay. It is laminated with PE foil, thus eliminating the need to additionally lay a damp-proof membrane.
25,000 x 1,000 x 2 mm (Roll)
1 Pack 4 rolls = 100 m2
1 Pallet 40 rolls
