Reflectix ® – Reflective Insulation Reflectix ® technology was initially created by NASA, used as protective insulation material for astronaut suits. It was soon recognised as an excellent heat insulation product, widely used in construction. What is Reflectix ® ? Reflectix ® is a multi-layer reflective insulation consisting of two external, high purity layers of aluminium foil covering layers of AirCap ® bubble and Cell-Aire ® polyethylene foam. How is heat transferred? There are three ways heat moves from warm to cool regions: ● Radiation – electromagnetic transfer of energy through space. ● Convection – heat flow transferred by the movement of air. ● Conduction – heat flow through a fluid or solid material. Convection Conduction Radiation Radiation 1 2 3 4 Anti-corrosion layer High purity aluminium foil AirCap ® bubble Cell-Aire ® Polyethylene Foam
The story behind the technology How does Reflectix ® work? While the aluminium reflects up to 95-97% of heat transferred via radiation, AirCap ® and Cell-Aire ® provide the necessary mechanical strength to the final product. They also give additional thermal resistance to heat transferred via conduction. With Reflectix ® Without Reflectix ® According to U.S. Reflective Insulation Manufacturers Association (R.I.M.A.), heat transmitted via radiation represents at least 50% of all heat transferred in nature. Traditional thermal insulation like foam or fibres are resistant to heat transferred via conduction, but are unable to reflect more than 30% of the heat transmitted via radiation. The benefits of aluminium? Compared with other surface materials, aluminium foil has superior reflectivity: Surface material Reflectivity (%) Aluminium foil 95% - 97% Asphalt 2% - 10% Brick 7% Concrete 5% - 15% Glass 5% Limestone 10% - 84% Marble 7% Paper 8% Plaster 9% Steel 88% There are three heat transfer directions Radiation Convection Conduction According to an analysis performed at Penn State University, approximately 75% of total heat transfer in structures occurs through radiation. The foil in Reflectix ® reflects 95 - 97% of the radiant energy striking it. An example of down heat flow is through the floor in the winter or through the attic in the summer. Up heat flow is through the ceiling in the winter. Side heat flow refers to heat loss through the walls.
