With the mercury levels dipping down, we resort to all sorts of methodologies to protect ourselves from the harsh winters. Room heaters keep us warm and protected within the confines of our home, but pose a great threat to the foundation and structure of the home.
Apparently, the warm and moist air in a heated room turns into vapors upon cooling. These vapors find no way to escape from a well-covered and secure room. In such cases, steam stagnates in the walls and while doing so, comes in contact with the cold outer walls of the house and condenses.
This condensation process can be very harmful. This is because water stagnated on walls and ceilings can make foundation and structure of the house vulnerable to moisture and other weakening agents. In order to protect house against it, people install vapor barrier that shields the indoor walls from these vapors.
So how does a vapor barrier work?
A vapor barrier is a thin and steam tight sheet, which prevents steam diffusion. A good ventilation system along with air tightness will suffice in most of the cases. In places like swimming pools, kitchens etc, the difference between interior and exterior temperature is higher. A good vapor barrier becomes a necessity in these cases.
Houses in U.S. or Canada which endure low winter temperature that fall below freezing point always need a vapor barrier. Vapor barriers are installed on the warmer side of the wall where the vapors generate, or else preferably, in front of insulation. This is mainly because to regulate the temperature, vapors travel from warmer to cooler places. These vapors later, penetrate walls and condense to form water which generates a greater risk of mold development on the walls.
How to select a right vapor barrier for your house?
All types of vapor barriers may not work well to secure the walls. There are multiple factors which are to be considered, studied and calculated before finalizing any option. Some of these factors have been discussed below:
1.The efficiency of a vapor barrier is derived by its Sd (vapor diffusion thickness) factor. This factor is basically the ratio of the resistance it poses to the steam and the amount of vapors produced in the room. Thus, a product with higher Sd value allows less amount of vapors to penetrate through it, as compared to a product with lower Sd value.
2.You also need to keep the location of your house in mind while selecting a vapor barrier. For example, if you live in Maryland then you can opt for a vapor barrier with higher Sd as the temperature remains pleasant throughout the year. If you live in places like New York, then installation of barriers with higher Sd value is greatly recommended.
3.Requirement for insulation also varies along with the location of your residence. For example, services like crawl space insulation NY provide specific insulation on crawl rooms as you cannot take a chance of accumulation of moisture in a room filled with electric wires.
After considering all these factors, choose best vapor barrier along with adept services like crawl space insulation NY for your home. A right choice can bring considerable difference for your home environment.
