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

A reflective insulation reduces radiant heat transfer across air spaces by use of one or more high reflective/low emittance surfaces (Reflectivity of 90% or higher - Emissivity of 10% or less). This rate of heat transfer can be quantified in an R-value (for a specific application).

Reflective insulation and radiant barrier are designed to block RADIANT heat. Radiant heat travels through space from a warm surface to a cooler surface. It can be heat from the sun, an electric heater, or even holding your hand above a warm stovetop. Reflective insulation will block up to 97% of radiant heat, while regular bulk insulation (fiberglass, foam, etc.) will only block 10 - 20% of it.

Reflective surfaces will give a greater performance when an air barrier is present (like behind a radiator). If buried within a cement layer then the reflective surface will now act as a conductor and transfer heat or cold. No useful gain can be attributed to a reflective surface when applied in this way. If choosing tile backer boards as insulation these types of boards can be expensive.

Yes, if you like.Our BTUFOIL tm Reflective Insulation and BTUBUSTERS tm PREMIUM RADIANT BARRIER can be used in conjunction with fiberglass insulation creates a highly energy efficient insulation combination. Together, both types of insulation can substantially help reduce energy costs.

Both radiant barriers and reflective insulation reflect radiant heat away from the building envelope. In fact we offer a line of radiant barriers called BTUBUSTERS tm PREMIUM RADIANT BARRIERS. The difference between the two is that a radiant barrier is used in an open space like an attic whereas reflective insulation is used in an enclosed space like a wall and a ceiling.

Our BTUFOIL tm Reflective Insulation is among the few insulation not affected by humidity. It's insulating value remains unchanged whether in a dry or very humid climate. In contrast, the r-value of mass insulation diminishes more than 35%, from an R-21 to R-13.65, with only 1.5% moisture content in the air. The average moisture content in homes typically exceeds 1.5%.

Reflectix is the Industry Leader! We manufacture the highest quality, most extensively-tested, readily-available, foil-based insulation and radiant barriers in the United States. With Reflectix? products, there is no middleman. We are the manufacturer and we operate with a quality management system certified to ISO 9001:2000. Our testing regiment is second to none.

R-value is a measure of the resistance to heat transfer. R-value does a good job of measuring the effectiveness of mass insulation but has no meaning in terms of the reflective protection against radiant heat.

As R-values are used to measure the effectiveness of mass insulation; Reflective and Emissive ratings are used to measure the effectiveness of reflective insulation with radiant heat. A high Reflective value helps block more radiant heat and a low emissive value means the insulating material releases less of the heat that it absorbs. Better performing reflective insulation like our BTUFOIL tm Insulation is made from 99.9% pure aluminum for very high reflectivity and very low emissivity.

An air space allows heat to be converted into radiant energy. Installing reflective insulation adjacent to an air space allows this radiant energy to be reflected away from the building envelope. The r-value of a horizontal assembly (e.g. stud wall) with our BTUFOIL tm Reflective Insulation is 6.8, downward (e.g. crawlspace or attics) it is 10.6 and upward (e.g. ceiling) it is 5.3. This effect is caused by the direction of convective airflow around the assembly.

Insulation is a term describing any material that reduces -- resists -- heat flow by conduction. Conduction is a physical property of all materials and along with "radiation" and "convection" describes one of three principal mechanisms of heat transfer. The conductance of a material is the rate of heat flow that is induced by temperature differences between one side of a specific thickness of the material and the other.

Yes. Our work pants are equipped with the required 2 inch wide retroreflective leg bands and they are positioned well above the required minimum of 2 inches from the bottom of the garment. This allows them to be worn in combination with CSA approved safety vests (or t-shirts) and armbands, or in combination with approved jackets, thereby fulfilling Class 3 garment guidelines pertaining to nighttime roadside workers in traffic conditions where speeds exceed 80Km/H.

FHD we want you to be happy with the products you have ordered, and therefore gladly accept returns.

Yes, although the treatment can take relatively up to a year long, additional use of a good sunscreen and sun avoidance is essential.

Nu Hair? formulae are specifically designed to help block the negative effects of DHT, the "bad" form of testosterone. This action helps prevent additional hair loss and enhances hair growth naturally.

Over time, head lice may develop resistance to some chemicals. It is important to check if a treatment you used has worked, and if not, treat again with another product that has a different chemical.
