I have had my conservatory for a year now and I suppose it is time to
put some blinds up. I am concerned as to how the blinds are fitted
into the conservatory. My conservatory is white plastic and surely if
I screw into it the fitting will not get tight, but what are the
alternatives. Also if I have material blinds made and do screw into
the plastic surely the screws will just pull out due to the weight of
the blinds?.

Has anybody got any suggestions?
