Radiant Barrier Roof Foil Underlayment

The Future of Cool Roof and Energy Saving Technology

When the sun heats a roof it is radiant energy that makes the roof hot.

When the radiant solar or sun energy hits the roof and heats the materials (shingles, tiles, roof panels, wood sheathing, etc.) and the dissipation of the radiant energy causes the underside of the roof surface and roof truss to heat the entire home (attics, attics, ceilings, etc.)

Roof and How Radiant Heat Works
Much of the sunlight’s radiation travels through the roof material to the attic and goes down all sides of the house. How radiating heat works is that the heat takes over cold areas as quickly as the heat can.

Since the hot roofing material radiates heat, it uses cooler roof surfaces, including air vents and attics to radiate heat. Radiation barriers reduce radiant heat transfer from the underside of the roof to other surface areas of the attic.

A radiation barrier reflects radiant heat that hits its surface and airspace away from the heat source and returns radiant heat to its surface and airspace. A radiation barrier is a roof material that deflects and retains radiant heat.

The roofing foil aluminum underlayment All About Roofing, LLC. installs reflects about 95% of the radiant heat that is produced by the Sun and roofing materials.

There must be 3-4 inches of airspace between the heat source and the wood sheathing. We do this by installing Arched Battens. Please refer to the slideshow below for more information on how Arched Battens work.

How Radiant Barrier Aluminum Roofing Foil Underlayment Works

Roofing Foil Underlayment
Cool Roofing System and Technology

The radiation barrier made from Aluminum foil has the properties of high reflectivity and low emission power. The radiant barrier film radiates from roof insulation to the sky (or back to the heat source). The low emission properties of the aluminum foil reduce the amount of heat it emits from the insulation – hence blocking out upwards of 90-95% of radiation heat that gets through the roofing foil.

Aluminum foil is a versatile, cost-effective, and easy-to-use material that can simultaneously serve as a heat shield and vapor barrier. Special low-cost aluminum foil materials are also available for radiation barriers in the attic. For basement walls that already have thermal insulation in place, unperforated aluminum foil can be used as an insulation material.

Radiant heat travels in a straight line, straight through the heat source and heat carrier. From there the heat source and heat carrier absorb some of the radiant heat but nonetheless the heat tries to penetrate as far as it can. Most common insulation materials work by slowing the conductive heat flow and to a lesser extent the convective heat flow. The result of radiant heat insulation is that not only is it a reasonable home improvement but 97% of the radiant heat is blocked and the structure of the residential or commercial building is cooled more effectively.

A radiation barrier reflects radiant heat that hits its surface and airspace away from the heat source and returns radiant heat to its surface and airspace. A radiation barrier is a roof material that retains radiant heat. The roofing foil aluminum underlayment All About Roofing, LLC. installs reflects about 95% of the radiant heat of the roof material.
