Isolating crawl space is important. Several comfort and energy issues are caused by inadequate or inadequate crawl space insulation. Any crawl space can get wet, so the insulation must be maintained in these conditions.
The best way to isolate a crawl space is to create it from scratch and think of it as part of an air-conditioned space as you would any basement. You can also look for the best crawl space insulation through various online sites.

Spray foam is fast, has a high R-value, provides an air and moisture seal, and fills any small hole. It's not a do-it-yourself job so it will be one of the more expensive options, but it will work well and the best part is that someone else is sneaking through your crawl space, not you.
When it comes to wall insulation, there are several options: Building codes require every crawl space over 1.5 feet high to have fire protection covering all foam products.
In this case, you can lay a concrete wall of 2×4 or 2×6 1 per centimeter; Placing it on top of small pieces of foam will protect it from contact with the soil and absorb moisture. Then spray foam is applied to the wall behind the nail and you can leave enough space in the cavity for the wires if necessary.
The foam must then be covered with plasterboard for fire protection, which can be attached to the spike wall. Apart from spray foam, no vapor barrier is required.
