Installing insulation in your home will benefit you in many ways. Fitting acoustic insulation within the cavity of internal walls and using acoustic plasterboard over the top is an effective method in reducing sound by up to 75%.
What is noise?
There are two types of noise categories; airborne and impact noise.
Airborne noise as the name suggests is sound that travels through the air. Every sound that you hear is airborne. Airborne sound can originate from outside the home such as traffic, aircraft, and dogs barking etc and from inside your home such as TV, music and voices.
Impact noise is vibrations that are carried through an object, like footsteps or vibrations made from large appliances such as washer and dryer. When vibration sounds become airborne, we hear it. Because sound travels in different ways different tools may be required in soundproofing your home.
Not every insulation type can reduce noise…
There are two main types of insulation categories; reflective and bulk insulation.
Reflective insulation acts as a barrier against radiant heat and has a reflective surface such as foil. This type of insulation can reflect the sun and its heat but will not act as a suitable sound barrier. The best insulation material for sound proofing is bulk insulation. Bulk insulation prevents the transfer of heat through millions of tiny air pockets created between the fibers of insulation, and traps heat from flowing through. Bulk insulation that has a high density makes the most effective soundproofing insulation.
What is the best soundproofing insulation?
As mentioned above, high density soundproofing insulation is designed to absorb and reduce the transfer of noise between rooms and from external noise sources. Most insulation brands make an acoustic insulation product specifically for soundproofing and insulating your home. Knauf Insulation has made a product called Sound Shield which is available in varying R-values and density ratings. Just remember that the R-value of a product indicates its ability to resist heat flow, so the higher the R-value the greater the insulating ability. The density of an insulation product refers to how compact the insulation is, so the higher the density the greater the sound absorbing capabilities.
Other ways to reduce noise levels
Using acoustic insulation is not the only way to reduce noise levels within you home, you may also consider the following;
- Using floor coverings such as carpet with an underlay – helps to absorb noise.
- Installing double glazed windows as an effective way of blocking external noise.
- Using curtains over windows can also assist in sound absorption.
- Having solid internal doors can also help seal door frames and keep noise within the room.
Unwanted noise can heighten stress levels and cause sleepless nights. Many homeowners simply put up with this as they are unaware of the soundproofing insulation products available. If you’re planning a new build or major renovation project, we recommend looking into your soundproofing options before it’s too late.
