This international search report has been established taking into account the rectification of an obvious mistake authorized by or notified to this Authority under Rule 91 (Rule 43.6bis(a)).
With regard to any nucleotide and/or amino acid sequence disclosed in the international application, the international search was carried out on the basis of a sequence listing:
2. Certain claims were found unsearchable
3. Unity of invention is lacking
4. Title of the invention
The text is approved as submitted by the applicant.

5. Abstract
The text is approved as submitted by the applicant.
The text has been established, according to Rule 38.2, by this Authority as it appears in Box No. IV. The applicant may, within one month from the date of mailing of this international search report, submit comments to this Authority.

The invention relates to a rectangular building element (1) which comprises a surface board (10) forming a first facing surface (2) located oppositely to a second facing surface (3) of the building element (1); a first edge surface (4) located oppositely to a second edge surface; a third edge surface (6) located oppositely to a fourth edge surface; and heat insulation material between the first facing surface (2) and the second facing surface (3), the heat insulation material comprising building foam (8a); and a plurality of rectangular, longitudinal support structures (9) arranged at a distance (L2) from each other, whose top surfaces (11) are arranged at a distance (LI) from a bottom surface of the surface board (10) by means of the building foam (8a). For the building element (1) to be able to effectively dampen sound originating from various sources, there is sand between adjacent support structures (9), which forms soundproofing adjacent layers of sand (8b) between the support structures (9), the layers being supported from below by the building foam (8a) and covered by the building foam (8a).

6. Drawings
