Buttercream Buttercream Buttercream is a type of icing or filling used either inside cakes, as a coating, or as decoration. Simple buttercream is made by creaming together fats (butter, margarine, or vegetable oil shortening) and powdered sugar to the desired consistency and lightness. Typically twice as much sugar as butter by weight is used. Flavorings, in the form of extracts and oils, may also be added. Some recipes call for cream, non-fat milk solids, flour, or meringue powder. There are two types of meringue-based buttercream: Italian and Swiss. The meringues must be cooled to room temperature in order not to melt
Spray foam polyurethane foam has the highest R-value of readily available spray foam insulation used in homes and buildings. Polyurethane is a closed-cell foam insulation material that initially contains a low-conductivity gas in its cells. As a result of the high thermal resistance of the gas, spray polyurethane insulation typically has an initial R-value around R-3.4 to R-6.7 per inch. In comparison, blown fiberglass typically has an R-Value of only R-3 to R-4 per inch. Foam insulation blocks all three forms of heat transfer: Spray foam is a very specialized packing material, often required for use in shipping valuable fragile items. Engineered
