Crawlspaces are host to a large number of conditions that may harm the house or inspectors. Never enter a crawlspace without proper personal protective equipment. Crawlspaces are notorious for the nasty discoveries made there by inspectors, and it isn’t hard to figure out why; for one thing, their cool, dark environment attracts undesirable pests and […]
Cool roofs, also known as reflective roofs, are roof surfaces designed to reflect radiation from the sun, reducing heat transfer into the building. How do they differ from conventional roofing products? Unlike most North American asphalt roofs, cool roofs are specially engineered to reflect much of the sun’s radiant energy back into space instead of […]
Condensation, also called sweating, forms on building materials when the temperature drops below the dew point, which is the temperature at which droplets of water vapor are forced so closely together that they coalesce into liquid water. Because of their characteristic thermal conductivity, components made of metal are usually the first places where condensation will […]
Collar ties and rafter ties are both horizontal roof-framing members, each with different purposes and requirements. Home inspectors should be familiar with these structural members and the differences between them, as they are not the same. Please note that, according to the International Standards of Practice for Performing a General Home Inspection, the inspector is […]
Brominated flame or fire retardants (BFRs) include a wide range of chemicals added to household furnishings and products to inhibit their ignition and reduce the chance of fire. In recent years, concern surrounding the toxicity of this class of chemicals has risen due to the widespread accumulation of several types of BFRs in humans and […]
Biowalls — also referred to as living walls, vertical gardens, green facades, and green walls — are interior or exterior walls that are covered with living vegetation. Biowalls have practical applications for both indoor and outdoor use. Many indoor biowalls are implemented in homes and offices for their natural air-filtration properties, and are used in […]
Bathroom ventilation systems are designed to exhaust odors and moist air to the home’s exterior. Typical systems consist of a ceiling fan unit connected to a duct that terminates at the roof. Fan Function The fan may be controlled in one of several ways: Most are controlled by a conventional wall switch. A timer switch […]
Bamboo is a type of hollow grass native to many areas of the world, most notably the Far East and Southeast Asia. It is sometimes thought of as the “poor man’s building material” because of its widespread cultivation and use in tropical climates where much of the world’s poor live. Many of these cultures find […]
An attached garage is a garage that is physically attached to a house. Fires that begin in attached garages are more likely to spread to living areas than fires that originate in detached garages. For this reason, combined with the multitude of flammable materials commonly found in garages, attached garages should be adequately sealed from […]
