| FRAGILITY* |
Fully fixed Mardome rooflights, when tested by the methods
described in ACR[M]001:2000 and prEN1873, are classified
as non-fragile |
* The test defined in ACR(M)001:2000 is applicable to in plane rooflights
only: however, if for comparison the principles of the test were applied to out-of-plane rooflights, then the classification obtained would be as shown.
Dome rooflights are out-of-plane and are therefore more visible which
means there is less chance of the rooflight being walked on accidentally thus reducing
the risk of accidents. |
