If you notice a gap between the louvres, the first thing to check is that the louvres have been installed correctly. Please refer to the instruction manual to check this. You can find the instruction manual for your Pergola here: Pergolux Instruction Manuals.
If the louvres have been installed correctly and there is still a gap, please reach out to our team via email- customerservice@pergolux.au with your order number and photos of the louvres for further investigation.
