Asbestos Vermiculite Insulation
Friday, March 11th, 2011
Can I put unfaced batt insulation (R30 Value) over old fluffy loose insulation in the attic?
A salesman at Loews told me I should remove all the old fluffy insulation with a powerful shop vac and just put the new faced batt insulation in the attic. What is your experience and advice on this matter to get the most energy efficiency and drop the heating and AC bills? The house was built in the 50’s and I wouldn’t be surprised if the insulation is that old too. I realize this old insulation may have vermiculite or asbestos but I plan to wear a mask and goggles. Any more advice you can offer?
You do not want to go anywhere near the vermiculite – it IS asbestos. If you think it is – have it tested. You can put unfaced batts over the old blown in fiberglass dont use faced – the insulation has to breath or it will sweat and develop mold. Check out the blown in stuff it comes in bales at Lowes – its much faster to install and Lowes has the machine.
