Inquiry (采购产品): doblle window Dear Sr, My name is Marco Aurélio and I'm a civil engineer and acoustic consultant here in Brazil. At the same time, I'm developing a master tesis on doblle windows. I'm getting bibliografy on this issue in order to start writing my teses. I'd like to know how the systems you use works? For example, the kind of material, the way the secondary window moves and is installed. All the information is very usefull for me, since I could not find many books here in Brazil concerning this issue. Thanks a lot. I'll be waiting for your reply. Sincerely yours, Marco Aurélio **** Hidden Message ***** Marco Aurelio 97015030 BRA Company: www.confortus.com Title: Acoustic Engineer E-mail: confortus@confortus.com **** Hidden Message ***** confortus@confortus.com
