Under Roof Reflective Insulation

This highlights a key problem with reflective products.

Under roof reflective insulation.

Convection conduction and radiation. Performance claims are based on an assembly including an air gap and the perfectly shiny surface when the product is installed. Dust accumulation on the reflective surface will reduce its reflective capability. Found in major outlets such as in home depot s insulation aisle reflectix comes in tightly spooled rolls of 25 by 2 feet of shiny reflective foil look bubble wrap texture insulation in plastic bags.

Low e reflective insulation resists all three types of heat transfer. Polyurethane spray foam metal roof insulation.

The idea is that this thin material can act as a type of insulation in tight spaces where you cannot put thick fiberglass insulation. Reflective insulation is made from. Radiant barriers and reflective insulation systems work by reducing radiant heat gain.
