Security barrier for providing protection in public space

1. A security barrier for providing protection in a public space or the like, said barrier comprising a mineral wool assembly comprising at least one mineral wool element having an outer liquid impermeable covering and wherein the at least one mineral wool element is adapted for being filled with a liquid.

2. A security barrier according to claim 1 , wherein the security barrier is filled with a liquid, said liquid including water.

3. A security barrier according to claim 1 , wherein the density of the at least one mineral wool element in its dry state is 75-200 kg/m 3 .

4. A security barrier for providing protection in a public space or the like, said barrier comprising a mineral wool assembly comprising at least one mineral wool element having an outer liquid impermeable covering and wherein the at least one mineral wool element is adapted for being filled with a liquid, wherein the at least one mineral wool element comprises man-made vitresous fibers and a wetting agent.

5. A security barrier according to claim 1 , wherein a plurality of mineral wool elements are provided adjacent each other.

6. A security barrier according to claim 5 , wherein the mineral wool elements form a common base surface of the mineral wool assembly with two opposite end surfaces substantially perpendicular to the base surface, and wherein top surfaces of the mineral wool elements are at different distances from the base surface.

7. A security barrier for providing protection in a public space or the like, said barrier comprising a mineral wool assembly comprising at least one mineral wool element having an outer liquid impermeable covering and wherein the at least one mineral wool element is adapted for being filled with a liquid, wherein the covering is a coating.

8. A security barrier according to claim 1 , wherein the liquid impermeable covering is a covering foil and/or fibre laminate, such as glass fibre laminate or a carbon fibre laminate.

9. A security barrier according to claim 8 , wherein the outermost layer of the laminate is a covering foil.

10. A security barrier according to claim 8 , wherein the foil or fibre laminate is adhered to the mineral wool element(s) by an adhesive, such as a liquid adhesive or a powder adhesive, which is insolvable by the liquid to be filled into the security barrier.

11. A security barrier according to claim 8 , wherein the fibre laminate is adhered to the mineral wool element(s) by resin of the fibre laminate.

12. A security barrier according to claim 1 , wherein the liquid impermeable covering is provided with a predetermined colour scheme, such as printings of logos or the like.

13. A security barrier according to claim 1 , wherein an opening for liquid filling is provided in the liquid impermeable covering, such as in the upper portion of the mineral wool assembly, for instance in the top surface thereof.

14. A security barrier according to claim 13 , wherein there is provided a liquid filling cover covering the opening.

15. A security barrier according to claim 1 , wherein a metal sheet cover is provided on one or more of the sides of the barrier.

16. A security barrier according to claim 1 , wherein a moisture detection sensor is provided in the mineral wool assembly.

17. A method of manufacturing a security barrier according to claim 1 , said method comprising the steps of:

providing a mineral wool assembly comprising at least one mineral wool element, and

mounting an outer liquid impermeable covering around the mineral wool assembly.

18. A method according to any claim 17 , whereby the step of mounting an outer liquid impermeable covering involves spray coating of the outer surface of the mineral wool assembly.

19. A method according to claim 17 , whereby a plurality of mineral wool elements are provided adjacent each other and adhered to each other to form the mineral wool assembly, and whereby the mineral wool elements are secured to each other in discrete spots prior to the coating.

20. A method of preparing a security barrier for providing protection in a public space, wherein the method comprises the steps of:

positioning the security barrier manufactured by a method according to claim 17 , and then filling the security barrier with a liquid.

21. A security barrier according to claim 1 , wherein the at least one mineral wool element includes mineral wool fibre products dispersed throughout an entire volume of the at least one mineral wool element.

22. A security barrier according to claim 1 , wherein the at least one mineral wool element includes at least 95% voids and is capable of absorbing water.

23. A security barrier according to claim 8 , wherein the laminate includes 2 to 8 layers.
