[LMB] (OT) AKICOTL: attic insulation

[hoffman2 at globaldial.com]

Dear Folks,
I installed (Sheep) wool,insulation in my home and find that it is very 
efficient. Last few winters I have not had to use heating in my main rooms and 
the first few days of a heatwave in summer are OK sans airconditioning too, 
after a few days the ambiant air and walls are warmed up as my home is of 
double brick with a tin roof, so on go the airconditioners.
I agree with Leslie that "batt" format is the best, for ease of electrician 
access, ceiling repair etc. The sheep wool is treated with fire retardant and 
is safe, it is cheap and has no cancer links and is a renewable resource. Your 
roof space will have a slight "woolly smell", but I have found this not 
unpleasant. Sheep wool insulation is also a good audio insulator, a must for me 
as I live near main roads and 2 KM from an airport.
Regards
Lois Rasmussen
