Abstract
A prefabricated underlay material (1) for location between upper surface of a load-bearing floor (8) and a continuous surface material (9), which underlay material comprises a substantially flexible sheet material (2) and dampening projections (3) formed of porous resilient material on one surface of the sheet material and distributed along the surface. Dampening projections (3) comprise strips (13) of foamed polymer or polymer mixture bonded to a first surface (11) of the sheet material without deformation of the surface thereof, which strips are located continuous, or intermittently continuous, with intervals (S) and are either principally straight or substantially undulating.

A prefabricated underlay material for location between an upper surface of a load-bearing floor and a parquet or other continuous surface material, which underlay material comprises:
- a substantially flexible first sheet material having a first surf ace with a surface area;
- dampening projections formed of porous resilient material on at least said first surface of the first sheet material, distributed along said first surface and having a total projection area less than said area of the first sheet material, wherein:
- said first surface extends continuously and flat beneath the dampening projections and in the area between them;
- and
- said dampening projections formed of porous resilient material:
- are made of a foamed polymer or polymer mixture bonded to said flat first surface by effect of its/their material properties at the time for manufacture;
- and
- are principally straight continuous or intermittently continuous strips located with intervals, or substantially undulating continuous or intermittently continuous strips located with intervals;
- the underlay material further comprising a substantially flexible second sheet material having a third surface to which said porous polymer(s) forming the dampening projections is also bonded by effect of its/their material properties at the time of manufacture, and which second sheet material is located on the opposite side of the dampening projections relative to the first sheet material.
A prefabricated underlay material for location between an upper surface of a load-bearing floor and a parquet or other continuous surf ace material, which underlay material comprises:
- a substantially flexible first sheet material having a first surface with a surface area;
- dampening projections formed of porous resilient material on at least said first surface of the first sheet material, distributed along said first surface and having a total projection area less than said area of the first sheet material, wherein:
- said first surface extends continuously and flat beneath the dampening projections and in the area between them;
- and
- said dampening projections formed of porous resilient material:
- are made of a foamed polymer or polymer mixture bonded to said flat first surface by effect of its/their material properties at the time for manufacture;
- and
- are principally straight continuous or intermittently continuous strips located with intervals, or substantially undulating continuous or intermittently continuous strips located with intervals,
- wherein said first surface of the first sheet material is glueless.
A prefabricated underlay material for location between an upper surface of a load-bearing floor and a parquet or other continuous surface material, which underlay material comprises:
- a substantially flexible first sheet material having a first surface with a surface area;
- dampening projections formed of porous resilient material on at least said first surface of the first sheet material, distributed along said first surface and having a total projection area less than said area of the first sheet material, wherein:
- said first surface extends continuously and flat beneath the dampening projections and in the area between them;
- and
- said dampening projections formed of porous resilient material:
- are made of a foamed polymer or polymer mixture bonded to said flat first surface by effect of its/their material properties at the time for manufacture;
- and
- are principally straight continuous or intermittently continuous strips located with intervals, or substantially undulating continuous or intermittently continuous strips located with intervals,
- wherein said dampening projections have sticky melt adhering properties when substantially in a molten state, and non-sticky, non-adhering properties in temperatures below its melting point or melting range.
A prefabricated underlay material for location between an upper surface of a load-bearing floor and a parquet or other continuous surface material, which underlay material comprises:
- a substantially flexible first sheet material having a first surface with a surface area;
- dampening projections formed of porous resilient material on at least said first surface of the first sheet material, distributed along said first surface and having a total projection area less than said area of the first sheet material, wherein:
- said first surface extends continuously beneath the dampening projections;
- and
- said dampening projections formed of porous resilient material;
