Reflectix r value

Nowadays, the idea of converting the garage into a second living space or personal sanctuary i. Insulating your garage door is a great way to ensure that your garage space is comfortable enough so that you can work, play, or just hang out without freezing. Adding this layer of insulation helps prevent heat from escaping, but it also blocks cold air from entering the garage so that your vehicle can stay safely stored away from freezing winter winds. Finding the best garage door insulation kit for your home will depend on the size and type of garage door you have and what type of garage door insulation you want to use. Take a look at the top products below to find the best garage door insulation for your garage. Garage door insulation kits can come in many different types, including radiant barrier, fiberglass, foam, and cellulose.

Why Reflective Insulation?


What is an R-value? Why are Air Spaces required in every application? What is Reflectivity? What is Emissivity? How does Emissivity provide benefit in a Radiant Barrier? Click on the pdf below to find the Air Space Requirement for your application. Reflectix is the Industry Leader! We manufacture the highest quality, most extensively-tested, readily-available, reflective-based insulations and radiant barriers in the world!

We are the manufacturer and we operate with an ISO certified management system. Our testing and validation requirements are second to none. Ease of installation and diversity of applications are two major advantages. All that is required are simple hand tools and access to the installation area. Conductive: In applications where an R-value is noted Radiant: These applications are referenced as providing a radiant barrier benefit.

Both products contain the same metalized aluminum and can be utilized as reflective insulations or as radiant barriers. The key difference is in the structure. It ensures a continuous reflective surface, and prevents air leakage that can result in condensation. This makes for very efficient performing reflective insulation assemblies quantified in R-values. A reflective insulation is a material or assembly that reduces the rate of radiant heat transfer across air spaces by use of one or more highly-reflective surfaces.

This rate of heat transfer can be quantified for a specific application by an R-value. For either a reflective insulation or a radiant barrier, an air space of a minimum thickness is required on the reflective side of the product. The reflective insulation benefit is derived from the interaction of the highly-reflective surface with the air space.

If the reflective surface is in contact with another building material, it becomes a conductor transmitting the energy by conduction. An air space may be specified on one or both sides of the product always on a reflective side. Enclosed air spaces, when instructed, are required to provide the stated R-value.

In the same primary way fiberglass or other mass insulations provide benefit, reflective insulation reduces conductive heat transfer. When a highly-reflective material such as our product is installed in a building assemblage, in conjunction with an air space, it provides a quantifiable R-value level of benefit.

The higher the R-value, the more resistant a material or building assemblage is to conductive heat transfer. Some are very high and some are very low. Materials that are low or resistant to heat flow have higher R-values. Example: If a heat lamp is positioned shining on a 0. It will take dramatically longer to detect any increase in temperature on the opposite side of the batt if at all.

R-values for reflective insulations are dependent on two primary criteria: 1. Heat flow direction 2. And, the amount of air space in a closed cavity on the reflective side of the product in a building assemblage.

This is the reason our product has different R-values for different applications varying amount of air space and heat flow directions. These terms are related to heat flow directions. They are a part of the criteria utilized in R-value testing. For example, when testing a floor assemblage, heat flow down is tested. When testing for a wall system, heat flow horizontal is tested same for all conductive heat transfer insulations.

Calculated R-values consist of three factors individual resistances added to get the total resistance : 1. Substrate R-value 3. Enclosed air space R-value on one or both reflective sides of the product. Also, the product labels and the website please refer to the pdfs at the top of this page contain additional specifications on enclosed air space requirements. The R-value for fiberglass mass insulations originates in the density, thickness and the physical composition of the material.

Example: A 3. It can also be manufactured to an R-value of 13 by increasing the density of the fiberglass same width of 3. One component that affects the R-value of a specific product or assembly is internal convection.

The primary reason that fiberglass does not produce different R-values when tested up or down, is that fiberglass batts do not exhibit internal convection.

Where within a reflective insulated assembly, the convective component influences the amount of heat transferred based on direction Up and Down. With multiple layers of product and airspaces between each layer, enhanced performance will be gained. An example of this would be the hot sensation you feel on your skin when walking from shade into direct sunlight.

This quality makes for excellent radiant barriers. Radiant Barrier is a material that is a poor re-transmitter of infrared waves radiant energy. This equates to a cooler attic, resulting in a house that requires less air conditioning usage to maintain comfortable inside temperatures.

This is the reason attics are so hot during the day. This is the reason when a low emittance sheet is installed below a roof plywood decking in an attic that such a substantial reduction in radiant energy occurs.

For either a reflective insulation or a radiant barrier, an air space is required on the reflective side of the product. An air space must exist on a minimum of one side of the product always on the reflective side residential attic — preferably oriented facing down. Radiant barriers by definition do not require an enclosed air space to provide benefit. This application radiant barrier is typically installed in a ventilated attic. The product has a very low re-transmission rate emissivity of radiant energy.

A cooler attic results in a cooler house requiring less air conditioning usage. This can be a larger number if there are ducts mounted in your attic space. R-values describe the rate at which energy is transferred through a material or assembly. No, absolutely not. There has been significant testing on this issue and it has been proven that a Radiant Barrier installed in a residential attic will have not have any detrimental effect on the shingles.

No, ventilation is not required, but it is extremely helpful when addressing convective heat transfer. If an attic system has a mass insulation such as fiberglass , a Radiant Barrier and a ridge vent, it has addressed three types of heat flow; conductive, convective and radiant within that system.

Reflectix does not recommend radiant barriers installed in a blanket fashion on the floor of the attic. Over time, the accumulation of dust on the upward facing surface will dramatically reduce the thermal performance of the product.

Dust is not an issue when the product is installed directly to the decking, the side of a truss or the underside of the rafter. Specific Topics What is an R-value? These are 3 ways that heat moves from warm regions to cool regions: Conduction: Heat flow through a material Convection: Heat flow transferred by the movement of air Radiation: Electromagnetic transfer of energy through space.

Reflective side of product: R Spacers are used to provide an air space where one is not present. There are several.

Click to see full answer Beside this, what is Reflectix used for? Reflectix is a reflective insulation that looks like silver bubble wrap. It's commonly used in attics as insulation. It reflects heat, and works best if there's a small dead air space between it and whatever you're insulating you can use a small strip of reflectix to create that space. Also Know, is Reflectix safe?

Nontoxic/noncarcinogenic. Does not require protective clothing, goggles, or respirator. Ideal for basement walls, crawl spaces, or attic. Has R value for.

Is Reflectix waterproof?


If we could give you any advice for your build, it would be this: Do not skip steps or take shortcuts, especially when it comes to bus and van conversion insulation. Bus and van conversion insulation is necessary for preventing heat transfer. High-quality materials are effective at resisting heat transfer. The R-value is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window, or a complete wall or ceiling, resists the conductive flow of heat.

And, for your safety, the EMF protection dome comes with a copper grounding rod. To varying degrees, different types of insulation products reduce heat transferred by either, conduction, convection or radiation. For example : A foam cup insulates and attains a small R-value, while the heat from a thermos is reflected back inside and reflects away exterior cold. In this illustration radiation is reduced to a minimum by silvering the thermos. Would you rather drink coffee from a thermos jug or a foam cup hours later?

A reflective insulation system consists of thermal insulation composed of one or more low-emissivity surfaces between which there are air gaps. A radiant barrier system, on the other hand, is a sheet of reflective material which is applied facing an air gap. The big difference between the two systems is that the R-value is measurable only in reflective insulation. Radiant heat, the main source of heat transfer, is infrared radiation.

Click to see full answer. Simply so, does reflective insulation really work? Radiant barriers and reflective insulation systems work by reducing radiant heat gain. To be effective , the reflective surface must face an air space. Radiant barriers are more effective in hot climates than in cool climates, especially when cooling air ducts are located in the attic.
