Microfoil Reflective Foil Insulation

MicroFoil rolled reflective insulation is a 1/4" thick, it is lightweight and flexible, 97% Radiant and 99.995% Vapor Barrier.

MicroFoil has a patented 1" self-taping foil flange running down one edge (48" and 72" widths only) with an additional 1" flange running down the opposite edge the entire length (16" and 24" rolls have staple flanges on both sidesfor inside joist/wall cavities).

Microfoil is the#1 Reflective foil insulation to use under metal roofs, in attics, walls, and with radiant infloor heating systems. MicroFoil is a clean, non-toxic, easy to install, self-taping radiant and vapor barrier that provides increased comfort, energy efficiency, and savings.

MicroFoil ™ effectively reflects a heat source as opposed to absorbing and dissipating it as fiber glass insulations do. This reflectivity works both ways: radiating summer heat outward and retaining winter heat inside.

Radiant Barriers do not have an R value since the R-value for reflectivity cannot be measured. However, radiant barriers can be tested as part of an assembly where the R-value can be observed and measured. In this case, the R-value can be achieved when the radiant insulation is installed as tested. R-values cannot be estimated based upon different installation methods.

R value is a measure of thermal performance, the higher the R value the greater the insulating value.

Independent testing by US Testing Laboratories

When installed correctly, MicroFoil™ provides an excellent thermal and vapor barrier, greatly reducing condensation buildup.

• MicroFoil does not contain hazardous chemicals or harmful materials that cause itching or respiratory problems.
• Condensation control
• Scrim reinforced for strength and durability
• Lighter and easier to handle than other products

To get the marked R-value, it is essential that this insulation be installed properly.

Barrier Install Instructions and technial data

Recommended Installation Instructions

The Barrier™ material is the easiest and LEAST labor intense under concrete material to install in underground applications on the market today. Just follow these simple steps and find out why installers rate this material “Easiest to Work With”.

1. Base platform material should be as level as possible, with all debris removed.
2. Unwind Barrier roll with tape edge up,then lay flat on base material.
3. Cut ends to length required - or roll up the footer form if desired to insulate the slab completely from heat and cold migration.
4. Lay next roll down - be sure to butt roll edges together.
5. Peel back double faced adhesive and compress on tape (make sure rolls are tight together) Compress over- lap tab firmly on previous roll edge. **It is important to make sure rolls are butted tightly together to create a seamless gap when you compress the double-faced adhesive tab.
6. 
   

Material: 3/8" thick extruded expanded polystyrene foam, 4'x 60' rolls.

Test Method(s)

The industry standard Thermal Conductivity Resistance test method using ASTM Standard C-518 - "Standard Test Method for Steady-State Heat Flux Measurements and Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus" was used for testing.

The Barrier was also tested as part of an 8" concrete assembly to create a realistic installation setting. In this test case, the assembly with Barrier has an R value of 4 and with the Barrier XT -an R value of 5.7.

Water / Vapor Permeability Values

The industry standard Water Permeability Test Method (ICBO Sections 4.6.1 & 4.6.2) and Water Vapor Permeability Test Method (Procedure B of ASTM E96) were used for moisture transfer testing.

Additional Comments by testing facility:

"This product meets or exceeds the ICBO conditions for acceptance. At the end of 24 hours, there was NO indication that any water had dripped from the underside of the specimens. In fact, a 3.5" head of water (rather than the required 2.0" head for 24 hours) was employed, with the same results after a period of 96 hours".

ALL TESTING HAS BEEN PERFORMED BY A CERTIFIED TESTING LABORATORY: GEOSCIENCE LTD. - Laboratory Testing Division.

Note: These typical property values are intended as guidelines only, and not as specification limits.

R-Value means resistance to heat flow, the higher the R-Value, the greater the insulating power.
