Difference Between Radiant Barrier And Reflective Insulation

Dust accumulation on the reflective surface will reduce its reflective capability.

Difference between radiant barrier and reflective insulation.

How does it stack up to radiant barrier foil. The term radiant barrier is supposed to describe products that reflect over 90 of radiant energy and these paint products simply cannot do that. The purpose of a radiant barrier is to reduce summer heat gain and lower a home s cooling costs but not in the same way thermal insulation does. The radiant barrier foil product line offered by innovative insulation inc.

The reflective bubble products have strength and substance from the bubble that are ideal for a wide variety 40 of applications residential and industrial commercial. When installing attic insulation a case can be made for both radiant barrier sheathing with typical types of insulation as well as spray foam insulation. A reflective insulation is an insulation system typically composed of closed cell foam fiberglass mylar air bubbles or shredded newspaper plus 2 low emittance reflective surfaces plus trapped air spaces. That means more than 95 of radiant heat is reflected.

Let s get some facts straight. Has minimum emissivity properties of 05. A radiant barrier is a single reflective surface used alone that faces an open space such as a wall cavity or attic. These are the numbers of conductive not reflective insulation.

Both products contain the same metalized aluminum and can be utilized as reflective insulations or as radiant barriers. Radiant barrier or foil insulation consists of a highly reflective film mounted to a substrate material such as cardboard kraft paper oriented strand board or plastic. The difference between reflective paint and radiant barrier foil. There is no such thing as radiant barrier paint.

A radiant barrier is a fairly thin product that is about the thickness of a standard business card. The key difference is in the structure. And that means quite simply radiant barrier foil is a far more efficient option than spray on coatings. The radiant barrier should be installed in a manner to minimize dust accumulation on the reflective surface.

Radiant barriers and reflective insulation systems work by reducing radiant heat gain. A quality radiant barrier has a reinforcement layer in the middle typically referred to as a woven scrim to make the product strong and tear resistant. Radiant barrier sheathing is inexpensive and reflects thermal radiation to keep attic spaces cool.
