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
Acoustic foam Acoustic foam Acoustic foam is an open celled foam used for acoustic treatment. It attenuates airborne sound waves by increasing air resistance, thus reducing the amplitude of the waves. Acoustic foam can be attached to walls, ceilings, doors, and other features of a room to control noise levels, vibration, and echoes. Many acoustic foam products are treated with dyes and/or fire retardants. The objective of acoustic foam is to improve the sound quality by removing residual sound in any space.This purpose requires strategic placement of acoustic foam panels on walls, ceiling and floors, effectively eliminating resonance within the room.
