When building a home, there are many different goals. One of the chief goals, which is naturally taken for granted, is to provide protection from the elements. That is, after all, why early man first sought out that most primitive piece of real estate, the cave.
ฝากขายบ้าน In the northern parts of our country, particularly along the coast, there is the need to protect from moisture. This is a chief concern, and everything must be designed with this in mind. Mold and rot can destroy many homes, so building needs to account for this. Certain types of insulation and certain types of wood are more susceptible to rot than others, and this needs to be looked at when selecting materials.
Oriented Strand Board (OSB) is manufactured in different ways for different applications. They are marked interior and exterior. Exterior is made for outdoor, and is highly resistant to humidity and moisture. In the United States, OSB for construction must be marked "Exposure 1", and this tells you it is designed with humidity resistance. Any experienced carpenter will know they must use exterior grade OSB for their projects.
OSB is commonly used for flooring applications. One situation which arises in areas with heavy levels of precipitation is moisture becomes trapped under these floor panels. Since the OSB has a low moisture permeability, the trapped water can stay there for a very long time, and begin to emit noxious vapors, and may even allow mold spores into the home. One way to prevent this is to use a vapor barrier.
While the OSB example is a more obvious application of using materials in such a way as to work with the environment, there are less commonly accepted forms of alternative building. Many would ask why these new materials and techniques are not used, and often the only reason is a pervasive culture of being resistant to change.
A great example is radiant barrier. This can reduce the heat in attics by 20-30 degrees, which in home in a hotter climate, such as Florida, California and Arizona, will result in substantially lower heating bills, and will pay for itself 100 times over during the life of the home. Yet this is not a commonly used material!
Another very interesting example is the Box Beam. In dry climates, such as Las Vegas and Arizona, exposed wood beams have a very common unavoidable problem. The low humidity causes the remaining moisture within the beam to be drawn out, which invariably causes the wood to twist and check. Even if you lag bolt the beam and seal it as soon as you get it, it will still twist.
A great alternative is the box beam, which is built with kiln dried 1" material, and is far more resistant to this process. This means not having to have your beams refinished every 5 years and replaced every 15 years. And yet there are very few people using them!
In conclusion, do not shy away from building materials because they are not commonly used, or you will shut yourself off from the fruits of innovation. The majority of homes today are being built in an almost identical fashion to homes of 100 years ago, despite the fact that all kinds of new materials have been invented which can and will provide a superior home. Don't fall prey to the close mindedness and fixed ideas of the construction industry.
