Q/ "What do you reccommend for sound insulation? I want to use my conservatory for parties and am concerned about the noise for my neighbours."

A/ 35mm would be the best for sound insulation. I have looked through all my records and cannot find any industry data on the sound insulation properties. This is probably because the roof is only one element that affects it. Clearly the windows etc have a big role to play.
Hope that helps.
