Difference Between Radiant Barrier And Reflective Insulation

The radiant barrier should be installed in a manner to minimize dust accumulation on the reflective surface.

Difference between radiant barrier and reflective insulation.

A radiant barrier is a fairly thin product that is about the thickness of a standard business card. 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. The term radiant barrier is supposed to describe products that reflect over 90 of radiant energy and these paint products simply cannot do that. That means more than 95 of radiant heat is reflected.

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. Let s get some facts straight. And that means quite simply radiant barrier foil is a far more efficient option than spray on coatings. Dust accumulation on the reflective surface will reduce its reflective capability.

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. These are the numbers of conductive not reflective insulation. 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. To be effective the reflective surface must face an air space.

Radiant barriers and reflective insulation systems work by reducing radiant heat gain. A radiant barrier and reflective insulation product are very similar in that they both reflect an average of 95 96 of the radiant heat that strikes their surfaces across and air space. A radiant barrier is a single reflective surface used alone that faces an open space such as a wall cavity or attic. Has minimum emissivity properties of 05.

The radiant barrier foil product line offered by innovative insulation inc. 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. Both products contain the same metalized aluminum and can be utilized as reflective insulations or as radiant barriers. A number of factors should be taken into consideration when choosing between these two especially the climate zone that you re building in.

Radiant barrier sheathing is inexpensive and reflects thermal radiation to keep attic spaces cool. The difference between reflective paint and radiant barrier foil. The key difference is in the structure.
