Abstract (en)
The present invention provides a wall (1) comprising a first panel (3) and a second panel (4) defining the surfaces of the wall (1) and extending in planes substantially parallel to each other and a sheet of sound and/or thermal insulating material (5) located between the panels (3, 4); at least one elongate fixing element (2) formed of metal positioned between the first and second panels (3, 4), and having; first and second side surfaces (8, 9) arranged in a plane substantially parallel to the planes of the first and second panels (3, 4); wherein the first panel (3) is attached to the first side surface (8); the second panel (4) is attached to the second side surface (9); and wherein a mat (6) comprising from 20 to 95 weight % aerogel is positioned between the first panel (3) and the first side surface (8) of the fixing element (2), the mat having a compressive stress at 10% compression of at least 20 kPa or, if 10% compression is not reached before the maximum compressive stress, having a compressive strength of at least 20 kPa. A method of reducing thermal and sound transfer and an elongate fixing assembly for use in a building wall are also provided.
