What is a building material that blocks heat transfer between the air inside and outside?
insulation
When insulating a homes crawlspace does the paper side face the underside of the flooring above or does it face down?
Vapor retarder (commonly known as Vapor Barrier), is commonly used to keep moisture out of a defined area space or material. The 2006 International Building Code defines Vapor Retarder as follows: VAPOR RETARDER. A vapor-resistant material, membrane or covering such as foil, plastic sheeting or insulation facing having a permeance rating of 1 perm (5.7 ´ 10-11 kg/Pa × s × m2) or less, when tested in accordance with the dessicant method using Procedure A of ASTM E 96. Vapor retarders limit the amount of moisture vapor that passes through a material or wall assembly Vapor barrier is commonly used in crawl spaces to keep the ground moisture out of the insulating materials. In cold areas vapor barrier is applied to the WARM SIDE IN WINTER over the insulation to keep moisture from the living space from getting to the insulation and condensing as the air gets colder on the outside of the wall/floor. The building codes actually require this application in most areas. However, in crawl spaces there is usually a larger amount of moisture in the ground and most jurisdictions allow the vapor barrier material to be applied to the bottom of the insulation or crawl space side. Some jurisdictions require both sides. Remember that the newer codes require a vapor barrier on the ground in crawl spaces. IRC N1102.2.8 Crawl space walls. As an alternative to insulating floors over crawl spaces, insulation of crawl space walls when the crawl space is not vented to the outside is permitted. Crawl space wall insulation shall be permanently fastened to the wall and extend downward from the floor to the finished grade level and then vertically and/or horizontally for at least an additional 24 inches (610 mm). Exposed earth in unvented crawl space foundations shall be covered with a continuous vapor retarder. All joints of the vapor retarder shall overlap by 6 inches (152 mm) and be sealed or taped. The edges of the vapor retarder shall extend at least 6 inches (152 mm) up the stem wall and shall be attached to the stem wall. Ask your local building inspection department for advice and clarification on the best application in your area. Hope this helps! Terry NEW ANSWER To answer the question, you want to insulate the foundation of the crawlspace. Where the house meets the foundation is called the sil box. That is where 90% of the outside air is infultrating your crawlspace. Stop the problems where it starts, The foundation.(the exterior walls).

What size heating and cooling system is needed to 2800 sq ft?
About 48,000 BTU You need to have load calculations done. Insulation, windows, location, outside temps, shade conditions, etc. will all affect the answer. For a shop with no windows and very good insulation or in a moderate climate, 48,000 btu may be sufficient. There are heating and cooling load worksheets available on the web if you know the R-value of your insulation and window type.
