Ecofoil radiant barrier foil attic insulation (1000 sf)
EcoFoil Reflective Attic Insulation is NEW and IMPROVED!
* Perforated for just enough breathability
Perforated Radiant Barrier is the latest discovery in supreme attic insulation. It consists of a single layer of polyethylene, sandwiched between two sheets of perforated reflective foil. Radiant Barrier can significantly reduce heating and cooling costs in the summer and winter, in turn saving you from high energy bills.
Size: 4' x 250' Roll (1,000 sq. ft.) Perforated Radiant Barrier
Perforated Radiant Barrier Specifications
1.) EcoFoil Attic Insulation is new and improved.
2.) Our metalized aluminum radiant barrier is the toughest in the industry. Each 1,000 square foot roll weighs 28 pounds and is virtually impossible to tear. If you are not satisfied we will return the product and refund you 100% of your purchase.
3.) EcoFoil Metalized Aluminum Radiant Barrier is the most reflective of it's kind and reflects nearly 97% of radiant heat.
4.) EcoFoil is the first to pass the ASTM E84-2009 test which is the industry standard for testing products for flame spread and smoke development.
All radiant barrier tested under older versions of the E84 test that have not been retested are not Class 1 / Class A products under the new testing criteria. The criteria was changed because the previous methods allowed for the product to be mounted inside the test chamber using poultry wire. This is not how radiant barrier is installed in real world applications such as an attic. Old products, made from pure aluminum will not pass the test without using poultry wire. These older products made from pure aluminum spread flames and smoke quickly when poultry wire is not used. Remember - We don't use poultry wire to install radiant barrier in an attic. With that said, please do yourself a big favor and only install a Class 1 / Class A insulation product in your attic.
5.) Our radiant barrier is a Class 1 / Class A insulation product under the new ASTM E84-2009 testing method. Learn about the ASTM E84 fire test .

Benefits Of Using EcoFoil Reflective Radiant Barrier In Your Attic:
* Effective in extreme temperatures-both hot and cold
* Strong but clean, lightweight and flexible
* Safe to handle with no special clothing or breathing equipment
* Cuts and installs easier than fiberglass
* Easily stapled, nailed or glued into place
* Waterproof, non-absorbent surface
* It's the only Class 1 / Class A fire rated radiant barrier that has passed the ASTM E84-2009 test.
How Heat is TransferredTo best understand how a radiant barrier works we must first understand the different ways that heat is transferred.There are three ways in which heat is transferred from warm spaces to cold spaces:Conductive: the transfer of heat flowing through a solid or fluid material.Convective: the transfer of heat which involves the physical movement of air when it is warmed Radiant: the movement of invisible heat rays from a warm surface to a cooler surface through an air space Heat Gain and Heat LossUp to 75% of upward heat loss (through roof) is in the form of RADIANT heat.Up to 80% of sideways heat loss (through walls) is in the form of RADIANT heat.Up to 90% of downward heat gain (entering through roof) is in the form of RADIANT heat. Do I need a perforated or solid radiant barrier?In certain applications a radiant barrier MUST be perforated to allow water vapor to pass through it. For example, when used on the attic floor the perforated radiant barrier must be used. This is necessary because during the cooler months, if there is no effective vapor retarder at the ceiling, water vapor from the living space may condense (and even freeze) on the underside of a radiant barrier lying on the attic floor and cause water damage to the ceiling and any existing attic floor insulation.
