Low density board photo gallery

James Hardie manufactured LDB as a material with the asbestos bonded to a calcium silicate. This material had brand names of 'Asbestolux' and 'Duralux'. Both were manufactured in thicknesses of 4.5mm, 6.5mm, 9.0mm and 12mm and they had either a bevelled, square edge or a recessed edge for flush jointing. (the jointing cement was also manufactured with asbestos).

LDB was manufactured as flat sheets and with perforations to assist with noise attenuation.

See the asbestos products gallery for common locations of other types of asbestos containing materials in buildings.

Asbestos cement sheet vs LDB
LDB perforated ceiling sheets.
Photo 1: LDB perforated ceiling sheets that are 4.5mm thick and holes that are 4.4mm in diameter. The holes dampened noise and are in patterns of squares and rectangles. Note, the flush finish of the nail fixings.

Photo 7: This is a Hardie’s LDB flat sheeting that has been painted over. Timber cornices and architraves have been used where the wall and ceiling sheets meet. This is typical of a home built in 1950s.

Photo 8: This is a Hardie’s LDB flat sheeting that has been painted over. Timber moulding have been installed over the join of the two wall sheets. This is typical of a home built in 1950s.
Note, moulds can be used in a horizontal or vertical position.
Ceiling tiles manufactured from LDB
Photo 9: Ceiling tiles were manufactured from LBD from either 9mm to 12mm thick sheeting and could have been either a flat sheet as shown above or perforated with 4.4mm holes to assist with noise attenuation. The edges of these sheets have raw edges and are not sealed.

Hardie's LDB flat surface sheeting
Photo 11: This is a Hardie’s LDB flat sheeting that has been painted over. These sheets have machined finished bevelled edges. This is typical of a home built in 1970s. A timber cover strip has been removed revealing the underlying original green paint.
Machine finished bevelled edges
Photo 12: A closer view of the machined finished bevelled edges and rectangular machined marking on the face. Note, the flex sheet nails finished flush with the sheet and the soft nature of LDB indicated by the damage around the removed nail hole.
Asbestos cement sheet vs LDB
Photo 13: Similarities of asbestos cement sheet (painted blue) versus LDB (painted yellow). The LDB would feel noticeably lighter and has ‘furrier’ edges because of the much larger asbestos fibre content.
LDB and asbestos cement sheeting
Photo 14. The differences between asbestos cement sheeting (labelled A) and LDB (labelled B). The LDB has a matted finish compared to a smooth finish on a non LDB sheet. There is also a definite colour difference between the two products, with LDB lighter in colour.
Screwdriver used with light pressure on LDB
Photo 15: A screwdriver used with light pressure on LDB left an indentation on the sheet surface, signifying the softness of LDB compared to asbestos cement sheeting (to which screwdriver would not have left indentation).
LDB ceiling sheet torn from the ceiling battens
Photo 16: LDB ceiling sheet torn from the ceiling battens. The corner of the sheeting remains attached with a flex sheet nail. Torn is an apt descriptor because LDB tears like cardboard.
Heads of fasteners recessed into the surface of LDB sheeting
Photo 17A: The heads of fasteners, nails and clouts are often embedded or partially embedded or recessed into the surface of LDB sheeting due to the softness of the sheeting.
Heads of fasteners in asbestos cement sheeting sit above the surface
Photo 17B: In contrast to the photo 17A, the heads of the fasteners in asbestos cement sheeting do not sit level with the surface but sit above the surface as seen in this photo.
Ragged or torn edges of broken LDB
