REFLECTIVE FOIL LAMINATES

Reflective insulation mainly resists radiant heat flow due to its high reflectivity and low emissivity (ability to re-radiate heat). It relies on the presence of an air layer (gap) of at least 25mm next to the shiny surface. The insulation is installed across the rafters before the brandering is nailed down, thus providing the air gap. The thermal resistance of reflective insulation varies with the direction of heat flow through it. Reflective insulation is usually shiny aluminium foil laminated onto paper or plastic and is available in rolls. These products are known as reflective foil laminates (RFL). A layer of reflective foil insulation is an effective membrane and barrier to radiant heat and as a condensation barrier. For optimum energy savings install in conjunction with conventional bulk insulation.
