Roof for the pergola

[SaudisLoveAudis]

Hi All,
I hope you are well.
I am erecting a decent size wooden pergola ~4x4m however I haven't made my mind re type of the roof surface.
The roof will by about 5x5m in size.

I did cover my patio with clear (fully transparent) EzGlaze polycarbonate that does not block UV but of course I want UV blocked under the pergola.

Do any of you have installed EzGlaze on the pergola but used a different colour that blocks the UV e.g. Grey or Breeze?

This document on page 2 lists all of them and their Shading Coefficient

I don't want a twin wall polycarbonate as this is a bit of a mess to finish and it gets dirty inside.

Or should I just cover the roof with wooden boards then cover with felt?
Of course I know that EzGlaze would probably come twice as expensive as the boards and felt.

Please advise
Thank you
