I want to go according to the plans here:
http://pat.home.mchsi.com/SAP.html
This is according to Jon M. Risch's plans, right ?.
If I will go with Miraflex instead of ordinary fiberglass (health issues). Should I need to expect weird consequences for this choice ?.
According to this page:
http://www.owenscorning.com/around/i...s/miraflex.asp
The thickness of Miraflex is 8 3/4". But the question is, will Miraflex absorb as good as regular Fiberglass ?. If they absorb more or less the same, then how come people are still using regular fiber glass ?, is there a really big price difference between the two ?.
One last question, about the absorption coefficient of this DIY panel. Has anyone run any measures to see that the absorption coefficient is more or less constant throughout the entire frequency band ?. As long as it's 0.9/0.8 and above (from the starting frequency) then it should be good. But if it has variations, like from 1.2 at 900hz, to 0.5 at 4000hz, then it can't be good.
Whith commercial pannels I get a frequency table which always shows me a more or less constant absorption coefficient, so I believe this is pretty important in order to get good subjective results...
