We required a large writing space approaching 4m in length with no joints so we could use the board with our interactive projectors. After considerable research we found the cost of a single board prohibitive and tried another jointed system. The joints proved intrusive and heavily compromised the interactivity we required.
Having been burnt once we decided to try this system, butting two 1800 wide boards together to get 3.6m
The boards once fitted by our maintenance team have proved excellent. The joint is barely perceptible and has no impact on the interactivity of the projector. They clean well, are super robust and as a bonus because they are so rigid seem to minimise the effect of vibrations transmitted through the wall, always a problem with UST projectors.
All in all we are so happy we are kitting out another 3 classrooms with them. Oh and they look fab!
