How Radiant Insulation Works

On October 4th, 2011, posted in: Technical - Reflective by Comments Off

Let’s start off by defining that radiant insulation is an insulation system where the reflective material faces an open air space. The idea is that a reflective barrier facing an enclosed air space becomes “reflective insulation” with a measurable R-value. The Concept of Radiant insulation Standard types of insulation, such as fiberglass, foam, and cellulose..

Oxidation of Aluminum Foil Facings Used in Reflective Insulation

On June 8th, 2011, posted in: Technical - Reflective by Comments Off

Oxidation of Aluminum Foil Facings Used in Reflective Insulation: Aluminum is the material of choice to produce low-emittance facings. Aluminum has an emittance as low as 0.03, but as with many metals, oxidation can occur. Here we will attempt to clarify the process of aluminum oxidation, its effect on surface emittance, and its effect on..

Fundamentals of Heat Transfer

On April 4th, 2011, posted in: Technical - Reflective by Comments Off

Heat flows from a hot medium to a cold medium in three ways By radiation from a warm surface to a cooler surface through an air space By conduction through solid or fluid materials By convection, which involves the physical movement of air 1. Convection Conduction is the direct flow of heat through a material..
