Explanation:
According to the International Residential Code (IRC), every basement and sleeping room is required to have an easily operable emergency escape window. The minimum clear opening area of the window should be at least 5.7 square feet (0.53 square meters).
Reflective foil insulation reflects radiant heat, making it highly effective at reducing heat transfer.
Explanation:
According to the International Residential Code (IRC), the minimum allowed slope of graded soil next to a building's foundation is 6 inches of vertical rise for every 10 feet of horizontal distance away from the foundation. This is equivalent to a slope of 5% (0.05) or greater. This slope helps to ensure that water drains away from the foundation and helps to prevent water damage and other issues associated with moisture accumulation.
Explanation:
According to the International Residential Code (IRC), adding load to a wood truss, such as a water heater, is allowed only if the additional load has been verified as acceptable by a certified engineer.
Crawl space foundations are often used in areas with expansive soils to allow for flexibility and prevent potential damage caused by soil movement.
Gutters are designed to collect rainwater and channel it away from the foundation to prevent water damage and foundation problems.
Copper is frequently used for plumbing supply lines due to its durability and resistance to corrosion.
The air filter in an HVAC system helps trap dust, debris, and allergens, improving indoor air quality and protecting the system's components.
GFCI outlets monitor the electrical current flow and can quickly shut off power to the outlet if a ground fault or leakage of current is detected, preventing electric shocks.
Explanation:
Nails or screws in the floor are not considered to be a readily accessible component of a room.
A slope of around 2 percent (approximately 1/4 inch per foot) is commonly recommended for residential lots to facilitate proper drainage and prevent water accumulation.
The R-value of insulation measures its thermal resistance, indicating how well it resists the transfer of heat.
Explanation:
An electric heater is not a solid fuel heating device.
Solid fuel heating devices are designed to burn solid fuels such as wood, coal, pellets, and biomass to generate heat. Examples of solid fuel heating devices include wood stoves, pellet stoves, coal stoves, and masonry heaters.
Explanation:
The International Residential Code (IRC) requires rafters to be fastened to ridge boards or gusset plates if the pitch of the roof is greater than or equal to 3/12.
Smoke detectors are designed to detect the presence of smoke, indicating a potential fire, and provide an early warning to occupants.
