any advice on this point?? the harder the better?? beech, oak, mobila pine...??

answers?

Hugo, whatever you have access to will work fine (no balsa :D ) Around here the most common "housbuilding" wood is spruce and pine which is "softwood". if it can hold a snowloaded roof it will "and in fact it does a 1000000² times) work for a window. Florian

thanks! :wink: So, no special wood for inner windows...
