Custom Modular Homes USA 

Durability and safety

Although CMHUSA will build a home the ordinary way, its preference is to re-engineer the house plan and build a more durable home using high-strength modules.

According to Storm Ready, sponsored by the U.S. Government's National Weather Service, "Americans live in the most severe weather-prone county on earth." Although natural disaster may not be on a family's mind when first thinking about building a house, once severe weather is on the way, a house that withstood manmade pretesting may suddenly seem brilliant.

Safety: "Defense by modules": Rather than building a house the ordinary way, CMHUSA advocates re-engineering a house plan to manipulate such differentials as durability, weight, hidden structural detail and protection of materials during construction. And of course CMHUSA advocates having CMHUSA oversight during the manufacturing process.

Two types of durability to consider: The first is the durability of the structure being built. The second is the durability of a family's health, affected by living in the house:

• Structurally, wind loads can be critical: The floor system of a CMHUSA-acceptable module will be built to better distribute wind loads (as well as seismic loads from earthquakes) through the framing of the house. Despite the potential devastation of Tests One and Two, neither of these violent manmade tests will collapse the modules. Tip: There is a way to make a weaker home not built with modules feel less shaky on high-wind days: Before installing the sheetrock, have someone nail thin metal "stiffener" strips diagonally across the wall studs. Another tip: Unless the strips are recessed the sheetrock will bulge.

• Structurally, the enemy of wood construction is water and moisture. Water and moisture can cause warping and structural deterioration. Even warranties can be compromised. The ideal is to never let wood get wet. Wood that gets wet can swell. Then as it dries and shrinks, connectors may fit less securely. Although most of the damage may be out of sight, clues may be squeaks and even nail pops. Inside a factory, keeping wood dry is easy. Wet, damp or warped lumber and cheaper lumber that has not yet cured is unacceptable for a proper factory's precision equipment.

Regarding potential impacts on the durability of human health, examples might include the following:

• The less noise pollution the better: To the extent of excellent sound dampening by the floor system noted above (part of a CMHUSA-acceptable module), enhanced may be a homeowner's everyday comfort. Elsewhere in this Website see the book dropping example.

• Another health and safety actor is mold, although not everyone is affected the same way: 

• The problem is that mold spores are everywhere. Therefore, in building a house the ordinary way, outdoors in the open, rain may soak into the exposed wood. Moisture can lead to mildew. Mildew can lead to mold. Learn More: Understand mold during the building process.

• On the other hand, applying chemicals to exposed building materials may curtail damage and may help prevent mold growth as well, but chemicals may later off-gas into the finished home. Read the label. For more information, the material safety data sheet lists the toxicity and carcinogenic properties of a chemical.
