Insulated Radiant Barriers

Insulated Radiant Barriers

Radiant barriers are installed in homes—usually in attics—primarily to reduce summer heat gain, which helps lower cooling costs.

The barriers consist of a highly reflective material that reflects (or more specifically, re-emits) radiant heat rather than absorbing it. They don’t, however, reduce heat conduction like thermal insulation materials.

How They Work

Heat travels from a warm area to a cool area by a combination of conduction, convection, and radiation. Heat flows by conduction from a hotter location within a material or assembly to a colder location. Heat transfer by convection occurs when a liquid or gas is heated by a surface, becomes less dense, and rises (natural convection), or when a moving stream of air absorbs heat from a warmer surface (forced convection). Radiant heat travels in a straight line away from any surface and heats anything solid that absorbs the incident energy. Radiant heat transfer occurs because warmer surfaces emit more radiation than cooler surfaces.

When the sun heats a roof, it’s primarily the sun’s radiant energy that makes the roof hot. A large portion of this heat travels by conduction through the roofing materials to the attic side of the roof. The hot roof material then radiates its gained heat energy onto the cooler attic surfaces, including the air ducts and the attic floor. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.

A radiant barrier’s performance is determined by three factors:

• Emissivity (or emittance) – the ratio of the radiant energy (heat) leaving (being emitted by) a surface to that of a black body at the same temperature and with the same area. It’s expressed as a number a between 0 and 1. The higher the number, the greater the emitted radiation.
• Reflectivity (or reflectance) – a measure of how much radiant heat is reflected by a material. It’s also expressed as a number between 0 and 1 (sometimes, it is given as a percentage between 0 and 100%). The higher the number, the greater the reflectivity.
• The angle the incident radiation strikes the surface—a right angle (perpendicular) usually works best.

All radiant barriers must have a low emissivity (0.1 or less) and high reflectivity (0.9 or more). From one brand of radiant barrier to another, the reflectivity and emissivity are usually so similar that it makes little difference as far as thermal performance. (Most products have emissivities of 0.03–0.05, which generally corresponds to a reflectivity of 95%–97%.) Also, the greater the temperature difference between the sides of the radiant barrier material, the greater the benefits a radiant barrier can offer.

Radiant barriers are more effective in hot climates than in cool climates, especially when cooling air ducts are located in the attic. Some studies show that radiant barriers can lower cooling costs between 5%–10% when used in a warm, sunny climate. The reduced heat gain may even allow for a smaller air conditioning system. But in cool climates, it’s usually more cost effective to install more than the minimum recommended level of insulation rather than a radiant barrier.

Some Information to keep you Healthy:

The quality of indoor air inside offices, schools, and other workplaces is important not only for workers’ comfort but also for their health. Poor indoor air quality (IAQ) has been tied to symptoms like headaches, fatigue, trouble concentrating, and irritation of the eyes, nose, throat and lungs. Also, some specific diseases have been linked to specific air contaminants or indoor environments, like asthma with damp indoor environments. In addition, some exposures, such as asbestos and radon, do not cause immediate symptoms but can lead to cancer after many years.

Many factors affect IAQ. These factors include poor ventilation (lack of outside air), problems controlling temperature, high or low humidity, recent remodeling, and other activities in or near a building that can affect the fresh air coming into the building. Sometimes, specific contaminants like dust from construction or renovation, mold, cleaning supplies, pesticides, or other airborne chemicals (including small amounts of chemicals released as a gas over time) may cause poor IAQ.

11 Facts about Indoor Air Pollution

The list below shows the top 11 facts and concerns for poor Indoor Air Quality.

1. Indoor air quality is one of the EPA’s top five environmental risks to public health.
2. Despite this, almost 25% of Americans do not show concern about the air quality in their homes.
3. Common indoor air pollutants include dust mites, pollen, mold, radon, carbon monoxide, excessive carbon dioxide, and other chemical fumes.
4. Pollution inside typically is two to five times worse than the air outdoors. Sometimes it can be 100 times worse.
5. Secondhand smoke from tobacco projects are a major indoor air pollutant. It contains about 4,000 chemicals, including 200 known poisons.
6. Secondhand smoke causes over 150,000 respiratory problems in infants and 38,000 deaths annually.
7. 10% of Americans have never changed the filter on their heating and air conditioning unit.
8. 75% of Americans live with someone who suffers from asthma, allergies, or other respiratory illnesses.
9. Poor indoor air quality can cause or contribute to asthma, headaches, dry eyes, nasal congestion, nausea and fatigue.
10. One out of 15 American homes has a dangerously high radon level.  Radon naturally emits from the earth and enters the home through cracks in the foundation floor and walls, drains, and other openings. Indoor radon exposure is estimated to be the second leading cause of lung cancer.
11. Only 27% of Americans have carbon monoxide detectors at home. Carbon monoxide is a gas that can stop coordination, worsen heart conditions, and at very high levels, can cause death.
