How To Make Walls Quiet — Drywall Systems

How To Make Walls Quiet. The advent of high quality audio systems and home theaters has changed the building environment completely. Where hotels, motels, homes, condos, and apartments previously only needed to deal with isolating a neighbor's voice, we must now contend with loud movies coming from next door, even when the sound is simply coming from a good television.

Emissivity Coefficients Materials - Engineering ToolBox

The emissivity coefficient - ε - indicates the radiation of heat from a 'grey body' according the Stefan-Boltzmann Law, compared with the radiation of heat from a ideal 'black body' with the emissivity coefficient ε = 1. The emissivity coefficient - ε - for some common materials can be found in the table below. Note that the emissivity coefficients for some products varies with the temperature.

Sustainability of gypsum products as a construction material

Natural gypsum, shown in Fig. 25.1, is the most common raw material for production of binders.It is a soft mineral, attributed to sedimentary rocks, normally grey or with no colour, with a humidity of about 8–10%. Gypseous stone, a denser modification of gypsum that is composed of gypsum and sandy and clayey stone, is normally used to produce gypsum binders.
