In which of the following sound travels slowest?
In colloquial speech speed of sound refers to the speed of sound waves in air. However, the speed of sound varies from substance to substance: typically sound travels most slowly in gases, faster in liquids, and faster still in solids.
Does sound travel faster through a solid liquid or gases?
Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster.

Does insulated plasterboard reduce noise?
Its core has a higher density which means it provides a good level of sound insulation. The higher the mass of acoustic plasterboard is the better the soundproofing you get. To get the most of it, you can insulate thin walls and ceilings, particularly in blocks of flats.

Do you need a vapor barrier with foam board insulation?
Cold climates should use polyethylene plastic vapor barriers between the wall and insulation. Vapor barriers are often installed in basements and crawl spaces to prevent ground moisture from leaking in. In houses with spray foam insulation, however, vapor barriers are not necessary.
Does Housewrap go on before insulation?
The answer, happily, is yes. In fact, the two products combined make your home super-insulated from outside wind and weather. If you choose to install house wrap with rigid foam, generally, it should go under the insulation, not around it.
