We noticed the home we've lived at for 7 years now needs more insulation in the atticIt currently has about 2-3 inches of white puffy blown insulation between the trussesOn top of that is about 3-4 inches of FACED insulationBoth together only come up to the truss beamWe were told by a family member we should get more insulation, it wasnt enoughWe bought 12 inch UNFACED to add on top in the opposite directionMy question is, should the backing of the exisitng faced insulation be taken off?I read if there is existing insulation, faced should be pointing toward the living space but insulation should not be between as it traps moisture.(The previous owner has done a lot of short cut projects on the house and we dont know if what they did was correct).
The name of the ion P3- is phosphoride ionFalse, it is phosphide These elements form RbF, CaF2, AlF3 and XeF6 so it is Xenon since it foms the most bonds.
You are correct there should be no insulation between the facing and the living areaThe faced insulation should never have been installed on top of existing insulationThe facing serves as a moisture barrier to keep the insulation dry and to prevent condensation from formingIt prevents moisture from the warm living area from getting into the insulationIf you have the vapor barrier on top of the insulation then it will instead trap the moisture inside the insulationIt may be difficult to remove the facing, but you can give it a tryIt may be easier to just replace all the insulationPut faced batts down first with the facing to the living area, then top with unfaced batts in the opposite directionIt is better to have no facing at all, than to have the facing installed in the wrong position.
