Radiant Barriers: A Solution in Search of a Problem Radiant barriers are a type of construction material that have gained attention for their potential to greatly improve energy efficiency. These shiny panels or membranes are designed to slow down the transfer of radiant heat, with claimed benefits that range from reducing utility bills to enhancing indoor comfort. Radiant Barriers: A Solution in Search of a Problem explores how effective and practical it is to use radiant barriers in modern building design. This topic is especially important today as there is an increasing emphasis on energy-efficient construction due to environmental concerns and regulatory requirements. Understanding the true benefits and limitations of radiant barriers is crucial for anyone involved in building science, from architects to homeowners. This article aims to dissect these claims and provide a grounded perspective based on scientific evidence and real-world applications. In addition to radiant barriers, other energy-efficient solutions such as crawl space encapsulation are gaining traction. This technique effectively seals off your crawl space from moisture, pests, and radon gas, thereby enhancing energy efficiency, air quality, and structural integrity. Understanding Radiant Barriers What Are Radiant Barriers? Radiant barriers are a type of building material used mainly to reduce heat transfer by reflecting radiant energy. These barriers are usually installed in attics or within wall structures to make a building more energy efficient. Unlike regular insulation materials, radiant barriers don’t have an R-value; they work by reflecting heat instead of absorbing it. How Do Radiant Barriers Work? The effectiveness of radiant barriers depends on their use of reflective materials, usually aluminium foil, which have low emissivity (low-e) surfaces. Emissivity refers to the material’s ability to emit absorbed heat. A low-e surface has an emissivity rating of 0.1 or less, meaning it reflects 90% or more of the radiant heat that hits it. This property is crucial in stopping heat from being transferred into living spaces, especially in hot climates. How Does Heat Transfer Work? To understand how radiant barriers work, you need to know the three main ways heat can be transferred: Conduction: Heat moves through a solid material from one molecule to another. Convection: Heat moves through fluids (gases or liquids) because of molecular motion. Radiation: Energy moves through electromagnetic waves without needing a medium. Radiant barriers specifically target radiative heat transfer. When installed correctly, they reflect radiant heat away from living spaces, reducing the cooling load on HVAC systems. For example, in an attic installation, a radiant barrier can significantly lower attic temperatures by reflecting radiant energy that would otherwise increase thermal loads inside the home. By using low-e surfaces and reflective properties, radiant barriers play a crucial role in modern energy-efficient building designs. They work alongside traditional insulation methods to create a more comprehensive thermal envelope for buildings. Evaluating Energy Savings from Radiant Barriers R-value Limitations The R-value is a standard metric used to evaluate the thermal resistance of insulation materials. However, it falls short when assessing radiant barriers due to their unique properties. Radiant barriers primarily function by reflecting radiant heat rather than resisting conductive heat flow, which makes traditional R-value measurements inadequate for capturing their true performance. Claims of Energy Savings Radiant barrier salespeople often make bold claims about significant energy savings, sometimes exceeding 40%. These assertions are frequently based on ideal conditions and may not reflect real-world scenarios. Key points to consider include: Reflectivity vs. Resistance: Radiant barriers reflect up to 95% of incoming radiation but do little to resist conductive or convective heat transfer. Climate Dependency: Their effectiveness varies greatly depending on climate. In hot climates with high solar gain, they can reduce cooling costs. However, in cooler climates, the benefits diminish significantly. Installation Quality: Proper installation is crucial. Without an air space, radiant barriers can become conductors of heat rather than reflectors. Comparative Savings: While some studies show modest reductions in energy consumption (typically around 5-10%), these savings often do not justify the high installation costs compared to other insulation methods. By critically examining these factors, it becomes evident that while radiant barriers have potential benefits, they are far from the miracle solution some marketers portray them to be. Common Misconceptions and Myths Surrounding Radiant Barriers Radiant barriers often find themselves at the center of conflicting opinions, ranging from being hailed as miracle solutions to being dismissed as outright scams. These misconceptions can cloud judgment and lead to uninformed decisions. Miracle Solutions or Overhyped? Exaggerated Claims: Some proponents tout radiant barriers as a cure-all for energy efficiency, promising drastic reductions in energy bills. While it’s true that they can reduce radiant heat transfer, their effectiveness is highly dependent on specific conditions such as climate and existing insulation levels. Misleading Comparisons: Marketers sometimes compare radiant barriers to advanced technologies like those used in space vehicles or NASA equipment, giving a false impression of universal applicability and performance. Scams and Misleading Claims False Promises: Scammers frequently target vulnerable populations, including senior citizens, with promises of up to 40% reductions in utility bills. Such claims are usually unfounded and exploitative. Non-Existent Products: Beware of products like “radiant barrier paint” marketed with low emissivity values. No paint exists that meets the low emissivity threshold of 0.1 or below required for effective radiant heat reduction. Improper Installation: Without appropriate air gaps, radiant barriers can turn into conductors rather than insulators, negating their intended purpose. Market Realities “Radiant Barriers: A Solution in Search of a Problem” encapsulates the dilemma faced by many homeowners. They must navigate between genuine benefits and overblown marketing rhetoric. Understanding these common misconceptions is crucial for making informed decisions about integrating radiant barriers into your building design. Comparison with Other Insulation Methods Radiant Barriers vs. Spray Foam Insulation Performance: Spray foam insulation acts as both a thermal and air barrier, providing superior performance in reducing heat transfer through convection and conduction. Radiant barriers primarily address radiant heat transfer. Cost-Effectiveness: Spray foam insulation typically costs around $1.50 to $3.00 per sq. ft., which is comparable to the cost of radiant barriers but

Crawl Space Mold Remediation North Carolina’s high summertime relative humidity cause vented crawl spaces to be highly susceptible to condensation, corrosion, wood rot, rust, and the growth of mildew and mold. When you reach out to Triangle Radiant Barrier for an expert crawl space mold inspection, you will get a thorough, professional assessment of your crawl space, and if we find mold, we have multiple options for crawl space mold remediation. We use a HEPA air scrubber with all but very minor remediation work.  This helps to ensure that any mold spores that are loosened into the air during the process are helped to be pulled out of the crawl space via the fan’s air flow and the micro-particles captures by a large HEPA filter.  Our first option for crawl space mold remediation is a fungicide application combined with HEPA Vacuum Scrubbing.  The fungicide is specifically designed to kill mold spores but does not remove any of the visible accumulated growth or staining the mold may have left on the wood surfaces of your crawl space.  The HEPA Vacuum Scrubbing helps to remove the visible accumulated growth from the wood surfaces. Fungicide application and HEPA vacuum scrubbing is our most affordable mold remediation method; however, it entails the use of chemicals (though EPA-registered, non-caustic, and non-toxic) and while it will remove visible accumulated growth from the wood surfaces, it will not remove aesthetic staining that the mold may have left in the wood. Our second option for crawl space mold remediation is fungicide application combined with Soda Blasting.  This will provide the same level of killing the mold, will remove all visible accumulated growth on the wood surfaces, and will help to remove the aesthetic staining that the mold left in the wood, on average about 70% of the staining.  This process does leave soda residue which serves as a natural deodorizer but can leave a fine white residue dust on all utility surfaces which may warrant additional cleaning at separate cost.  Our third option for crawl space mold remediation is Dry Ice Blasting.  We blast the crawl space wood surfaces with dry ice at a -110◦ Fahrenheit to instantly freeze and kill mold spores. Dry Ice Blasting fully kills any mold present, removes the visible accumulated growth from the wood surfaces, and removes nearly all, if not all, of the visible aesthetic staining in the wood surfaces.  Dry Ice Blasting is unique in that it remediates mold without the use of any chemicals and it is residue free, since dry ice sublimates directly from a solid to a gas. Deodorization and Sanitization If you are concerned about the cleanliness and smell of your crawl space, consider Triangle Radiant Barrier’s deodorization and sanitization options. Deodorization involves spraying your crawl space with a non-caustic blend of natural enzymes and non-pathogenic bacteria that encapsulates and neutralizes the decaying organic material causing the odor. Our sanitization services include manual cleaning of all crawl space utility surfaces with a hospital-grade disinfectant, sanitizer, and virucide. This method is highly effective against mold, bacteria, germs, fungi, and viruses. We often recommend using deodorization and sanitization as a complement to our other crawl space mold remediation services. Crawl Space Radon Inspection and Mitigation Radon is a naturally occurring gas from the soil.  While not common, it can be of sufficient concentration in some crawl spaces to present significant health hazards to home occupants, up to and including the risk of death.  Radon is not visible and has no smell.  The only way to determine if you have radon at levels of concern is to test for it. We sensors capable of providing ongoing monitoring and tracking of radon levels.  We also install radon mitigation systems to alleviate the concern, if it is present. Crawl Space Sump Pump and French Drain Not every crawl space needs a sump pump and/or French drain and, despite what some sales folks will tell you, they are not required by Building Code.  If, however, your crawlspace has drainage or ground water issues, we can help.  Often the solution may be viable outside the crawl space such as with improvements to gutters, landscape grading, masonry water proofing, or exterior drainage.  While we do not offer work outside of your crawl space, we have referrals for companies who can.  Or if those exterior solutions do not suffice, we can install a sump pump and French drain for you, as needed. Crawl Space Insulation and Vapor Barrier Triangle Radiant Barrier provides multiple options for crawl space insulation to include CrawlBarrier® rolled insulation, rigid foam board insulation, fiberglass insulation, and closed cell spray foam insulation.  Each insulation type has advantages and disadvantages.  We’ll help you to understand what options are viable and which may be right (or not right) for your situation.  We offer vapor barrier from 6-mil non-reinforced up to 20-mil reinforced.  We give lifetime warranties against degradation and delamination on our 10-mil reinforced or better vapor barriers which are made with 100% virgin polyethylene also guaranteed against any off-gassing or odors.  Crawl Space Dehumidification and Environment

Proper insulation makes for more comfortable homes, greatly reduces heating / cooling costs, and reduces a home’s carbon footprint.  There are many different types of insulation and each type has advantages (and disadvantages) depending on the unique aspects of each home. Triangle Radiant Barrier offers professional, high quality insulation services throughout Raleigh, NC and the surrounding Triangle area: Fiberglass Insulation (blown-in, rolled / batt) for attics, walls, crawl spaces Radiant Barrier Insulation for attics, walls Spray Foam Insulation (open cell, closed cell) for attics, walls, crawl spaces Air Sealing Crawl Space Encapsulation (also crawl space mold remediation) Attic Stair Cover Solar Attic Fans With so many options, which insulation is right for you and your home?  Contact us today and we’ll be happy to provide you with a free inspection and estimate.  In the meantime, here’s some useful information, to help your consideration. Fiberglass Insulation Fiberglass insulation is made of extremely thin glass fibers and is available as a loose-fill insulation for blowing in or comes in rolled batts, sometimes referred to as ‘blankets’.  Today’s fiberglass insulation is formaldehyde-free and non-combustible. Fiberglass insulation works by absorbing and holding onto heat, similar to the way a sponge absorbs water.  But, like a sponge, fiberglass insulation can become saturated…in this case, with heat.  When it does, the remaining heat will pass through it which decreases your home’s comfort and increases your costs for heating and cooling.  To gain better performance with fiberglass, you need more of it…the bigger the ‘sponge’, the more heat it can hold before reaching saturation. Triangle Radiant Barrier | What is the Best Insulation for My Home? Fiberglass insulation’s performance is measured by the “R-value” or the “Resistance Value”.  The “resistance” measures how long the insulation will prevent the transference of heat.  The higher the R-value, the longer it takes heat to transfer…so the higher the R-value, the better the performance.  R-value is based on the height or thickness of the fiberglass.  Currently Building Code standards in our area for attic floors is R-39 which is about 12-13” height of fiberglass insulation (actual R-value per inch varies based on the manufacturer of the insulation being installed). Fiberglass insulation works primarily against conductive heat transfer (transfer of heat through contact of materials).  However, it does not stop airflow, so it is not effective against convective heat transfer (transfer of heat through air movement).  Effective air sealing (e.g. sealing utility penetrations in the drywall surrounding the living space) is important to aid fiberglass against convective heat transfer. Fiberglass insulation has limited performance against radiant heat transfer (transfer of heat through the transfer of radiant energy and the relative transformation of that energy into heat). Fiberglass Insulation Pros Cons – Most affordable insulation type – Versatile in many different applications – Good against conductive heat transfer – With effective air sealing, works well with powered attic ventilation, such as a solar attic fan – Some performance as sound barrier – Least performing, relative to other insulation types – Must be accompanied by effective air sealing to help prevent convective heat transfer – Limited performance against radiant heat transfer – Deteriorates naturally over time, reducing performance and eventually need addition / replacement – Disintegrating fiberglass can be a detriment to indoor air quality – Does not moderate cold in winter attics   Radiant Barrier Insulation Radiant Barrier is a foil insulation designed to prevent the transfer of heat derived through radiation.  It does this in two ways: emissivity and reflectivity. Radiant energy comes from the sun.  That energy passes through space where it has no inherent heat because open space does not have mass or molecules to absorb the energy.  Eventually, the radiant energy hits the Earth’s atmosphere and encounters mass objects, such as your home’s roof.  Shingles and wood (that comprise your roof) have very high level of emissivity, meaning they absorb a lot of radiant energy which converts into a lot of radiant heat.  Your roof then re-emits radiant energy and radiant heat into the attic where it hits your wood framing, stored materials, and even your insulation and creates more radiant heat.  Radiant heat is the primary type of heat that accumulates in your attic in summer. Radiant Barrier has a very low emissivity, so it absorbs very little radiant energy and produces very little radiant heat.  Radiant Barrier also has very high reflectivity and it reflects 95% of radiant heat. There are different ways to install Radiant Barrier but a common method is doing so along the underside of attic rafters.  This method of installation reduces summer heat in attics between 30-40◦ F, on average. Radiant Barrier does not deteriorate over time.  It is a permanent insulation that comes with a lifetime warranty against degradation or delamination. In combination with air sealing and fiberglass insulation, the Radiant Barrier helps to prevent convective heat transfer but offers limited performance against conductive heat transfer. Our Radiant Barrier foil is perforated so it will not trap air moisture in attics. Radiant Barrier Insulation Pros Cons – Cost efficient, cost-effective – Greatly reduces attic heat (rafter install): lower heat saturation risk to fiberglass; less heat competition to attic-installed HVAC systems – Lifetime warranty, permanent insulation – With effective air sealing, works well with powered attic ventilation, such as a solar attic fan – Reduces risk of rodent activity – Class I / Class A fire resistant, non-combustible – No detriment to indoor air quality; no chemicals at install – Cannot be used in R-value requirements – Limited performance against conductive heat transfer – Not a substantive barrier to noise – Does not moderate cold in winter attics   Spray Foam Insulation Spray Foam provides superior R-value performance and air seal the attic and/or living space to which it is installed.  It provides excellent performance against conductive and convective heat transfer. When installed in an attic, the attic is essentially brought within the home’s thermal and pressure boundary and, for this reason, Spray Foam provides the best moderation of attic heat in summer and attic
