House built in 1968 with fiberglass in the atticHave looked at Radiant Barrier vs blown-in for the attic and blown for the walls Price is a consideration but not the main concernIs Radiant Barrier an easy do-it-yourself?? How long to do 1200 sf attic??
YesThe bigger the bowl the better, carefully fired of clay with a fair amount of grog in it to increase heat shock resistance And a layer of sand under the fire will both shield the clay and reduce the temperature underneath - remember if put on a table or bench, it may burn the surface through the clay.
