Support layer configured to provide acoustic and/or thermal insulation

A support layer configured to provide at least one of acoustic and thermal insulation, comprising:

• a base layer comprising a first side configured to be placed against a boundary surface of a space, and a second side configured to face away from the boundary surface and to be directed towards a cover layer;
• a plurality of primary carriers configured to carry the cover layer, wherein the primary carriers are resilient and extend a first distance from at least one of the first side and the second side of the base layer;
• and
• a plurality of auxiliary carriers configured to additionally carry the cover layer when the primary carriers are compressed due to a load being exerted on the cover layer, wherein the auxiliary carriers extend a second distance, the second distance being less than the first distance, from the same at least one of the first side and the second side of the base layer;
• wherein:
• the base layer comprises recesses defining cells and walls between the cells;
• the plurality of primary carriers extend from the walls of the base layer;
• the second side of the base layer comprises a substantially continuous surface defining a bottom of the cells;
• and
• at least one of the plurality of auxiliary carriers extends from the bottom of the cells towards the first side of the base layer.
