R-Value is 17.9 in which R means resistance to heat flow. The higher the R-value, the greater the insulating power. To get the marked R-Value, EFX SpectraTM installs this insulation by a trained professional. EFX SpectraTM products block 98% of radiant heat & infrared rays.


How does it work?

Unlike traditional attic insulation which can slow down heat transfer, EFX SpectraTM Multi-Layer Reflective Insulation helps reflect radiant heat back to its source.

How will EFX SpectraTM keep me warmer in the winter?

EFX SpectraTM uses advanced technology that will help hold the heat in the house just like wrapping a baked potato in aluminum foil. The potato stays warmer longer by holding the heat in.

How can EFX SpectraTM keep heat out in the summer?

EFX SpectraTM uses 99% pure copper & aluminum to reflect the suns radiant heat. Therefore, it keeps much of the radiant heat from saturating the insulation in your attic. The insulation stays cooler so your house stays cooler.

How does EFX SpectraTM address moisture problems?

Because of the specifically engineered size and spacing of the perforations, EFX SpectraTM allows moisture to escape. In addition, EFX SpectraTM has created a thermal break, the space between the two layers of 99% pure copper & aluminum. This increases the ability of the insulation to BREATHE even more!!!

What benefits can I experience?

Has EFX SpectraTM been tested by a qualified lab?

Yes! Energy tests were conducted by Johns Manville Technical Center. EFX SpectraTM passes the UL1715/ UBC 26-3 Room Corner Wall Fire Test and meets all requirements as required by the 2000 IBC. Many other products claim a Class 1 rating, however, some bubble- pack or foam core reflective insulation products generate a Flame Spread many times the 25 rating required to achieve a Class 1 rating. In addition, EFX SpectraTM passes the Intertek testing and meets all requirements for NFPA286 (2011 Edition) in conjunction with 2012 IBC Section 803.1.2 & Section 2603.10 for thermal barrier.

How is EFX SpectraTM installed?

EFX SpectraTM should be installed by trained technicians & is best when used in conjunction with existing insulation to block radiant plus heat conduction and convection. Common areas for installation are attic & crawl spaces, below radiant floors, on basement walls, on attic knee walls, & behind batts & on outside walls.
