second fan and replacing the first with one more powerful to do the firsts work as well as its own.

Thanks for your comment which I just read as I am unfortunately revisiting this subject. In the end we did install two fans, however ill-advisedly we put the air supply fan above one classroom. We were told with sound insulation we wouldn't hear it much but this is not the case. When you refer to air being drawn through any void causing mold problems, would this matter if the air were being drawn only from inside the building. Also, we live in a warm climate with high humidity in the summer and very low rainfall. Would this be a factor to consider? I'm considering this week turning off the

Thanks very much for the advice. It sounds like I want to be in cork heaven, I know, but the cork on the walls would only be like a continuos notice board and covered in part by the usual language school type posters. I didn't know about the corners and will give some thought to that. Maybe adding a tapestry and a bookshelf would achieve my aim. The problem is that with it being a classroom you're limited in home many things you can add to the room. Thanks again.

My reasoning for floor tiles is primarily the sound of scraping chairs but hopefully sound absorption as well. I currently have ceramic floor tiles and this with the reverb means a single chair moving interrupts the whole class. The wall panels would not be painted.

I fear this would look very poor aesthetically and I'm the type who always looks for a difficult solution. I actually love the look of cork and think in a classroom it would look great. If it were to succeed for the purpose of absorbing reverberation I'd be happy to make the investment.

From what I've read a good quality glued down - as opposed to floating - cork floor that is painted with polyurethane should last for many many years. Maintenance involves repainting.

Steven, by reverberation i'm talking about noise reflecting off walls for upto four seconds. Any noise is amplified; particularly high frequencies such as childrens' voices and scraping chairs. Da01, tapestries are something I'd thought about but I prefer the idea of cork - if it were to work - in classrooms as its more neutral aesthetically and easier to keep clean.

Have added the design digram. I´m thinking of branching from that 500x150 duct and having a short second run at 90 degrees in the first classroom.

Maybe a different design is what I was thinking, probably of a larger size. You can't actually see the register, it is above the metal grill in the photo and is adjusted by a screwdriver closing 6 widthways 'gaps'.

This might be a very good idea as it would halve the wind speed in the longer running duct. At the end of the my diagram - where the fan is - there is a turn of the duct to 90 degrees to the left. I could look into branching another duct from this for a shorter run in the first classroom. Don't know about dampers though, we have fibre ducts so I'll have to look into it. Thanks.
