Greenfab’s Modular Prefab Model Home
Seattle’s first ever LEED Platinum was open to the public from March 2nd to March 27th of 2011 but the owners have since moved in to enjoy their new home. Greenfab’s modular home is the first to be certified LEED Platinum in the State of Washington. The home is part of Greenfab’s 1300 Series now available nationwide at Greenfab.com. Greenfab’s homes are not only healthier and stronger but are also completed 50% faster then traditional homes built on-site.

Many homeowners believe that additional insulation means a tighter and more energy efficient home, but this is not always true. Most insulation does not stop air from penetrating the building envelope. It is especially critical to have a continuous air barrier that has the ability to stop all direct air flow into a building.

A blower door is a diagnostic tool designed to measure the airtightness of buildings. and to help locate air leakage sites. A blower door consists of a calibrated fan for measuring an airflow rate, and a pressure-sensing device to measure the air pressure created by the fan flow. The combination of pressure and fan-flow measurements [...]

Air flowing in and out of a build- ing can cause lots of problems; in fact, air leakage can account for 30 per- cent to 50 percent of the heat loss in some homes. But air flowing through a build- ing can help solve lots of problems too — as long as it’s the result of a blower-door test.

A blower door is a powerful fan that mounts into the frame of an exterior door. The fan pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings. The auditors may use a smoke pencil to detect air leaks. These tests determine the air infiltration rate of a building.

Learn and see how the rainscreen siding was done of Greenfab Modular Home. A rainscreen is the exterior weather-facing surface of an exterior wall detail that stands off from the moisture-resistant surface of the structural backup wall. The rainscreen is the first interruption between conditions that exist on the outside of a walled building and conditions that are required on the inside of a walled building.

Watch the application of Spray Foam insulation in a Greenfab Modular Home. Spray foam insulation is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of Isocyanate and resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes drilled in into a cavity of a finished wall.

A rainscreen is designed to prevent moisture entry by equalizing the pressure between inside and out and to extend the life of siding and sheathing materials. Thin strapping is attached to hold the siding away from the sheathing by a quarter-inch to three-quarters of an inch.
