Very few individuals these days simply cannot bear in mind a time when among the foremost types of dwelling insulation was not fiberglass. This is because it's been close to due to the fact 1938 when it had been initially released by Owens Corning.
1. Certainly, you are appropriate -- your attic needs At the very least 6 inches of cellulose in addition to the prevailing fiberglass. Before you decide to blow in the new insulation, having said that, it is vital to peel again the fiberglass batts and seal all of the prevailing air leaks.
One method to Enhance the air high-quality of your house is to guarantee your attic is adequately insulated. Though you may not imagine attic insulation as a powerful Option to improve air good quality, it can help hold pollutants, dust and allergens that can most likely enter your home via air leaks in your attic outdoors.

Martin, thanks for your Perception and data. I had a few concerns. my property is in Dallas and I just lately transformed out the roof which included radiant barrier around the decking. When I measure the decking temp in the summer its is remarkably cool but the roof rafters are surprisingly scorching.
Plywood and OSB have a greater emissivity than shiny aluminum. If your roof sheathing is plywood or OSB, as well as the roof sheathing is sizzling, it will eventually radiate heat to the attic ground.
Radiant barriers also can work with other warmth resources, for instance a stove or heater. Consequently, they may also be used in Wintertime to help keep heat from escaping your property, however These are more practical for a reflector (to keep warmth out) than being an insulator (to help keep heat in).

3. Furthermore Robert, Martin is right about R-benefit and radiant barriers. Not realizing The essential concepts of radiant Vitality transfer reflect in your incorrect conclusions regarding R-value and radiant barriers. I confer with your statement a couple of quotation from Martin, “One very simple distortion is ‘radiant barriers haven't any R-price’.” To split hairs even even more, there's no this kind of point as radiant heat, only radiant Electrical power. The two Cool garage aren't synonyms. Radiant Strength is made up of photons, it's the interaction of such photons with make a difference that produces warmth (and foil displays photons). R-value is actually a measure of thermal resistance to warmth flow; considering the fact that foil is usually a conductor then it does not Possess a resistance to thermal heat movement. So the foil itself offers no R-value by definition (mainly because it reflects photons not warmth). However, by reflecting photons from objects radiating energy (foil is not directly in contact with) it lowers absorbtion in the photons which lead to warmth. This ends in an noticed R-value boost of the issue it really is connected to.
Excellent write-up - have already been arguing this issue with my insulation man for years. Over the lighter side, any person else catch the radiant foil/barrier ads everywhere? Funny is sweet.
