Yo, all. I have removed a vestibule door in a hall 1.6m wide. I will be replacing the top light with some sapele I have left over. So having recently learned of the existence of integral blinds and the found that web sites don't provide online quotes. So my question is, what is a ball park figure for an area about 55cm x
150cm?
nb. I want a blind with open vent and close vent....not retract to the top.
Thanks.
Arthur
