I have a crawl space attached to a heated basement and has a opening to access it, my question is should the insulation be on the floor and the side walls or just the side walls, the floor gets very cold in the corner and i don't see any air leaks from outside, also it's a new addition (10yrs old) and it's only a 15x8 space.
Molecular compound - the sharing of electrons since aluminium and oxygen is a non metal they have a molecular bond
There are more exotic combinations than Al2O3, like the neutral molecule AlO2, and the anion AlO2^-, which is sometimes called aluminate and has a -1 chargeThe AlO3^3- anion is also called aluminateThere is no giving of electronsThe bonds in AlO2 or AlO2^- are covalentIn the AlO2^- anion there is an extra electron giving it the -1 chargeAluminum is the central atomThere is a double bond to one oxygen and a single bond to the other oxygen[O-AlO]^-
walls should be insulated , from the cold concrete walls .the floor above doesn't need it as its a heated basement and would stop the heat from neither side above or below ,so no need there unless you keep the basement at 50 and the room above at 72 .then it will help also most important is to put the insulation at the rim joist area , most insulation men call them blockers its the space at the end of the joist where it hits the sill ( this is part of the outside wall ) also insulate well and then check that corner again ( make sure that the sill seal is in place and doesn't have any gaps or breaks ) if so caulk it in .
