<p>Pipes and pipe components (10) are insulated in that an outer jacket (11) is centered around them, and a member (14) permeable to air but not to insulating material (15) is placed in the space between the pipe or pipe component (10) and the outer jacket (11) at one end thereof. By applying a negative pressure in the last-mentioned end to the outer side of the member (14) and by supplying at the same time the insulating material (15) to the other end of the outer jacket, the space between the pipe or pipe component (10) and the outer jacket (11) can be filled. After filling, a member (14) corresponding to said member (14) is positioned in the other end of the outer jacket, whereby the insulating materal (15) is retained in position. Alternatively, a binder is added to the insulating material (15) prior to or in connection with the supply thereof, whereby both the outer jacket (11) and the air-permeable member (14) can be removed after the binder has set.</p> |
