Jerry thanks for the comment getting back to you after the holidays. Creating an insulation layer and a vapor barrier between the concrete slab and the ground beneath it is the best practice in insulating basement floors. While it is always a good idea to insulate concrete slabs you don t need to do so especially in your climate. Insulating a basement is a great idea if it wasn t insulated when built as before we began insulating foundation walls and below slabs see slab on grade it was generally estimated that basement heat loss accounted for about 1 3 of the total heat loss of a house it is likely that such an abysmal starting place made the addition of any insulation at all seem sufficient so basements built to.

Buildings tend to lose heat in descending amounts form the top down. You want the most insulation in the attic tapering down to the base. Without insulation heat and cool air are easily lost through the floor. If you re planning on finishing a basement or portion of your home that has a concrete floor then it may be a good idea to insulate it before installing basement flooring.

For homes without basements and those with unheated cellars adding insulation can bring heating costs. Nothing good will come from insulating on top of a wet basement floor. Insulation also helps to preserve the air quality and reduce energy costs. 4b slab floors built directly on the ground.

The goal however is the same. While insulating these areas is important homeowners can also save money on their heating and cooling costs if they insulate the space under their floors.

There are two types of crawl spaces ventilated and unventilated and each requires its own form of insulation. If ground under the home is cooler than the basement temperature which is the case in almost every climate year round heat will naturally try to escape through the concrete slab. To enclose the space in a thermal envelope.
