Q: Should you insulate your entire attic?

• <div><p>Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills.

Q: Does a monolithic slab need insulation?

• <div><p>Monolithic slabs don&rsquo;t require insulation, but many homeowners choose to have their contractors install insulation under the slab during construction.
