Exploring Vapor Barriers With Buyreflectiveinsulation.com

Persons living in cold climate areas do appreciate the role an effective vapor barrier plays in their lives

. For those not in the know, a vapor barrier is an integral part of home insulation which has two main purposes. One is to control the movement of air or air escape through the walls i.e. it aids to keep heated air indoors. The second purpose is to block condensation forming between walls i.e. the phenomena that takes place when warm air makes contact with a cold surface.

The immediate and long term benefits of installing a vapor barrier include but are not limited to the following:

The home becomes more comfortable as there are no more cold drafts,

There is more energy efficiency since your heated air is retained in the house which also means that heating costs are reduced,

The materials used to build the house e.g. drywall, wood and insulation are protected from deterioration that comes in the form of mildew, moisture and moulds meaning your family is also safe from diseases that may be prompted by moulds.

Over the years there have been many types of vapor barrier that have been developed. Most of these vapor barrier types have not been truly effective or have been quite expensive. The treated paper vapor barrier for example is common but it is ineffective since it is difficult to achieve a perfect seal at the joints and edges. The black polythene paper vapor barrier which uses its black colour as an ultraviolet inhibitor can only be used on the outside and in areas where you require air cooling rather than air heating. Cross laminated/fibre reinforced polythene vapor barrier is only cost effective where high strength is required especially for rough or irregular surfaces. Foil insulation vapor barrier is one of the latest technologies in insulation. It is very cost effective and adds the R value to any existing insulation.

When installing a vapor barrier, the main principle to consider is to ensure that there is continuity. The vapor barrier should be tightly sealed between any two successive surfaces e.g. wall to wall or wall to ceiling using special tape. Previously, staple guns and acoustic sealants have been used. BuyReflectiveInsualtion.com has a pull strip for their AV1 foil insulation vapor barrier which provides an airtight fit. The vapor barrier should also be completely sealed at all penetrations and protrusions especially for the electrical and pipe boxes. This will prevent air from escaping which will otherwise defeat the purpose of the vapor barrier.
