The Recorders and Early Music Union did not like the sound of the latest ad for Pink Batts and filed an official complaint with the Advertising Standards Authority (ASA).
However, ASA has ruled that the ad is not out of tune.
The ad for Pink Batts' Silencer features a man wearing a pink onesie and playing a recorder, while a woman checks the noise reduction levels provided by the insulation, from the other side of the wall.
Pleased with the fact that no one has to hear how badly he plays the recorder, the man in the onesie says: "I love Pink Batts Silencer".
