A DPM (Damp Proof Membrane) roll, in the referenced size, is typically 1 metre wide when rolled but unfolds to a sheet that is 4 metres wide and 25 metres long, covering an area of 100 square metres.
Here's a breakdown:
- Dimensions: 1 metre (rolled width) x 4 metres (unfolded width) x 25 metres (length)
- Coverage: 100 square metres
- Gauge: 1000 gauge (thickness)
- Weight: Approximately 23kg
Therefore, a typical DPM roll offers a significant area coverage when unrolled, making it suitable for various construction and damp-proofing applications. The thickness (1000 gauge) indicates the level of protection it provides against moisture.
