Many of the builders offer high-grade insulation to improve the home’s exterior and protect interiors from outside weather. However, the thermal zones usually determine the level of air tightness in a factory-constructed home. One of the ways in which thermal zones improve the safety and sustainability of a manufactured home is through high-quality modules and R-rated insulation.
Just like abiding thermal zones, manufactured home builders also conform to the wind and roof load standards imposed by US Department of Housing and Urban Development. Not all homeowners may know about anchored module standards and precisely how modules resist wind and heat, and as to how the roof carries sidewalls weight. However, those HUD parameters exist for all manufactured homes.
There are three thermal zones in a manufactured home constructed in the US, and each HUD coded home abides thermal zones based on the climate in the area. HUD codes differ from state to state in the US and the home location determines the module’s air tightens and insulation.
The HUD also segregates thermal standards based on whether the manufactured home resides on fringe climate or humid climate zones. If your home resides in either zone, then the home exterior conforms to the vapor retardant standards of HUD with airtight sealants.
Roof Load Zones
There are three different roof load zones for HUD coded homes in the US, namely the North Zone, the Middle Zone, and the South Zone. Apparently, the roof-load zones differ based on where the home resides, and not based on where the climate-controlled factory is located.
Moreover, depending on the snowfall in an American county, the roof is loaded with rain gutter and is shaped flat, curved, pitched, or sloping downwards vertically. For instance, counties such as Colorado, Michigan, as well as Wisconsin experience heavy snowfall in the fall season than some of other states in the US. In which case, the loaded roof withstands pounds of snowfall with rain gutters, trusses, and roofline in a manufactured home.
Where to Find Detailed HUD Standards
The HUD mandates the manufactured home builders to put a date plate inside the manufactured home. The date plate displays the home’s thermal resistance, wind load and roof load zones, as well as displays whether the factory home has been manufactured to resist high snowfall and tornado or as per the state stipulates. Note that the date plate displays load parameters, and not the manufactured homes prices.
