Following research by Astins which investigated the benefits of reducing the standard width of plasterboard from 1200mm to 900mm, Midland Lead are pleased to announce that we are now able to produce lead-lined boards in the new width of 450mm to accommodate new size reductions in plasterboard width.
Astins, a leading dry lining contractor undertook a comparison study into the physical demands placed upon dry liners when handling standard 1200mm wide plasterboard versus 900mm plasterboard. The study sought to provide an assessment of the movement of the lower back, shoulder elevation and muscle activity when handling and fitting plasterboard.
Sustained elevation and internal rotation of the upper arm can lead to a decreased blood flow to the critical tendons around the rotator cuff. The study found that when using 900mm boards, shoulder elevations decreased by up to 41% and muscle activity also decreased by up to 90% for the dominant arm.
When looking at the lower back region, lifting 1200mm plasterboards compared to 900mm boards saw an increase in bending backwards and sideways. This movement pattern in conjunction with heavy load could increase the risk of injury to the lower back.
From a worker’s perspective, the 900mm were considerably lighter which made them easier to manoeuvre and easier to cut.
