What is the purpose of cladding?
To protect insulation from damage
Many good insulators are made up of?

To prevent condensation, a vapour barrier is installed where on the insulation?
On the warm side of the insulation
What is “R” value in insulation?
Resistance
The ability of material to resist heat flow
