Fondant icing sugar syrup, produced by processing fondant with invertase. Fondant fancies are a type of cake typically coated in poured fondant. "Rolled fondant," "fondant icing," or "pettinice," which is not the same material as poured fondant, is commonly used to decorate wedding cakes. Although wedding cakes are traditionally made with marzipan and royal icing, fondant is increasingly common due to nut allergies as it does not require almond meal. Rolled fondant includes gelatin (or agar in vegetarian recipes) and food-grade glycerine, which keeps the sugar pliable and creates a dough-like consistency. It can also be made using powdered sugar and melted
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
