A protective wall comprising two surfaces 3, 5 spaced from and parallel to each other, and an intermediate region 7 between them comprising substantially solid matter in the form of loose granular material 9 of a density less than 2000 kg per cubic metre and interstitial voids 11 such that the average density is less than 1400 kg per cubic metre. The granular material preferably has a density less than 1420 kg per cubic metre and the intermediate region may have an average density less than 1000 kg per cubic metre. The granular material may have a fracture toughness less than 1.6 MPa/m1/2, a melting point above 150 degrees centigrade and be one of polyoxymethylene, poly(methyl methacrylate), polystyrene, high-impact polystyrene, or a combination thereof. The two surfaces may comprise at least one layer of fibre-reinforced plastic material having a thickness of 3.5mm. The intermediate region may have a thickness of 60mm. Also provided is a shelter and method of constructing a shelter by coupling a plurality of the claimed protective walls to one another.
