except for the deep South. Energy savings are about the same whether you insulate on the interior or exterior. The best insulation to use is rigid foam, which is largely unaffected by moisture.

Why is foam insulation important?

The main advantages are: • Exterior foam insulation is often damaged during backfilling, and is difficult to protect above ground. There are a number of protection systems, but most get damaged over time.

How much density is type II foam?

Type II foam has a nominal density of about 1.5 lbs/cu ft. It is possible to place the insulation above the slab in a retrofit. There are two main approaches: Place 2x4s flat on the slab and insulate between them. The 2x4s can “float” or be secured with concrete nails or Tapcons.

Why put a sand or gravel layer over a vapor barrier?

For years, many industry experts recommended placing a layer of sand or gravel above the vapor barrier to absorb bleed water and, thereby, reduce the finishing time and curling. However, this was found to cause more problems than it solved. Water was trapped in the sand or gravel “blotter” for extended periods, leading to high moisture levels in the slab and basement — causing the very problems the vapor barrier was intended to solve. Placing the vapor barrier below the insulation creates similar problems by trapping water.

What is XPS foam?

Two-inch extruded polystyrene foam (XPS) is typically used as one-inch foam is too fragile to place under a slab. Expanded foam (EPS) is a less expensive option, and considered better for the environment, but you would need to use high-density Type II EPS for this application.

What is the best insulation for a basement?

Whether you spray it in place or install sheets, closed cell foam is the answer for basement insulation. When properly installed, closed cell foam (spray or board) provides two benefits: first and foremost it’s a great insulator with MUCH better R values per inch than fiberglass, and secondly when you use closed cell foam that’s at least 1-1/2 inches thick, it actually acts as a vapor barrier. So essentially you get a vapor barrier and insulation all wrapped into one easy to use product.

How do I install foam insulation in a basement?

Several years ago I insulated the basement walls in our basement storage room. I installed 1-1/2″ extruded polystyrene foam insulation board by DOW. I used a special Styrofoam adhesive to adhere the foam board to the concrete (you can also use “Great Stuff Pro” foam in a can). The foam board I am used comes with a tongue and grove so installation is pretty easy. Just cut the boards to length, apply some adhesive and press it against the wall. Note, you may need to apply pressure to the foam with boards until the adhesive dries.

We can use it in this situation because we have an insulated vapor barrier between it and the concrete. By doing the combination of insulation materials I achieved approximately an R values of 16. This was much cheaper than doing it all in foam.

Can fiberglass insulation be installed on concrete?

In this case only fiberglass insulation is installed between studs ( no plastic on concrete). A vapor barrier is installed, then drywall. This situation is really bad, water vapor from the concrete escapes into the stud cavity and condenses on the back of the vapor barrier behind the drywall.

How thick is a basement slab?

In older homes the slabs maybe only 2-3 inches thick (maybe even less). When a nail is shot into the tread plate it can create a path for pressurized ground water (located under the slab) to escape into the room (the room is at a lower pressure). Water will flow from high pressure to low pressure flooding the basement.
