The amount of UV blocked depends on the geometry of the mesh used in the screen lid , this depends on the mesh pattern , the wire diameter and the aperture see

Is very simple geometry problem to calculate the open area for PLANE mesh , bit more tricky for twilled mesh pattern , Dutch pattern and twilled Dutch patterns.
No 2 plane mesh blocks 30%
No 3 plane mesh blocks 35%
No 6 plane mesh blocks 38%
No 12 plane mesh blocks 38%
No 16 plane mesh block 44%
Refer to the data provided in the mesh maker's specifications PDF in the above post and http://www.haverboecker.com specs doc = P-17-E-kg.pdf
measuring it
no 2 and no 3 Plane mesh will be lower. Need to specify the aperture size and wire diameter to calculate the shade factor for the mesh.
From data in the UV report

Graph 1 see below :
can see the follow data for a tube in a reflector series 4 and 5. (the mesh tested was "no4 plane mesh" aperture 5mm).
