The article for insulation (1 , 101) according to claim 4 or 5, wherein said layer (3) comprises calcium hydroxide (9) in an amount comprised between 4 and 12 grams per each kilogram of said wool (2). 7. The article for insulation (1 , 101) according to any one of the preceding claims, further comprising a reinforcement (33) associated to the wool (2,3).
8. The article for insulation (1 , 101) according to claim 7 when dependent on claim 4, wherein said reinforcement (33) is inserted within said layer (30).
9. A use of an article for insulation (1 , 101) according to any one of claims 1 to 8 for thermal insulation or for acoustic insulation of a room delimited by at least one wall (30), wherein said article for insulation (1 , 101) is included in said wall (30).
10. A use of an article for insulation (1 , 101) according to any one of claims 1 to 8 for increasing the structural resistance of a wall (30), wherein said article for insulation (1 , 101) is included in said wall (30). 11. A method for producing an article for insulation (1 , 101) for use in the building sector or for constructions, wherein said article for insulation (1 , 101) is obtained by combination of wool (2, 3) and a stiffening material (9).
12. The method according to claim 11 , wherein a solution (8) including stiffening material (9) is distributed into the wool (2, 3). 13. The method according to claim 11 or 12, comprising the steps of
(a) providing a containment frame (10) provided with side walls (11) which delimit a support surface (12);
(b) arranging in said containment frame (10) an amount of wool (2) so that it forms a layer (3) which substantially covers said support surface (12); (c) adding an amount of solution (8) including stiffening material to said layer (3) of wool (2), so that said solution (8) including stiffening material is distributed within said layer (3);
(d) exerting a pressing action on said layer (3) in a direction substantially perpendicular to said layer (3).
14. The method according to claim 13, comprising the step of placing a reinforcement (33) parallel to said support surface (12), so that said reinforcement (33) be inserted within said layer (3) of wool (2).
15. The method according to claim 13 or 14, wherein said step (d) is accomplished by means of a press.
16. The method according to any one of claims 13 to 15, wherein said step (d) is accomplished by enclosing said layer (3) between two rigid elements (17, 19) having surfaces adapted to exert said pressing action in a substantially uniform fashion on said layer (3).
17. The method according to claim 16, comprising the step of arranging a sheet (18, 20) in plastic material between at least one of said rigid elements (17, 19) and said layer (3) prior to exerting said pressing action. 18. The method according to any one of claims 13 to 17, comprising the step of removing said article for insulation (1 , 101) from said containment frame (10) after said step (d).
19. The method according any one of claims 13 to 18, comprising the step of drying said amount of solution (8) including stiffening material within said layer (3) after said step (d).
20. The method according to any one of claims 13 to 19, wherein said step (b) or said step (c) is preceded by the step of washing said amount of wool (2) using water (25) at a temperature between 30 0C and 50 0C.
21. The method according to any one of claims 13 to 20, wherein said support surface (12) comprises at least one perforated portion.
22. The method according to claim 21 , wherein said support surface (12) comprises a grid (13).
23. The method according to any one of claims 13 to 22, wherein said support surface (12) is associated or associable to said containment frame (10) in a removable manner.
24. The method according to any one of claims 11 to 23, wherein said stiffening material is calcium hydroxide (8, 9)
25. The method according to any one of claims 13 to 23, wherein said stiffening material is calcium hydroxide (9), said solution (8) including stiffening material is an aqueous solution (8) of calcium hydroxide (9), and said amount of aqueous solution (8) of calcium hydroxide is such as to provide an amount of calcium hydroxide (9) comprised between 4 and 12 grams per each kilogram of said amount of wool (2).
First rigid sheep wool panel, for retrofitting existing or building new walls, basements, attics.
Because the WEKA panels can be mounted on existing walls or used in new builds, the need for insulation and dry walling is eliminated, reducing the overall budget of a project. Besides budgetary considerations, which I always appreciate, the ability for a product to positively affect the environment and its resources is always a list topper for me. In addition to the aforementioned “green” positives above, the use of wool in this product is providing a new source of income and stability for wool farmers and suppliers, and increasing the exchange of local and sustainable sources of insulation materials. Now that’s what I call, giving back. For more information, visit:
