This entry was posted on November 30, 2009.
Installing InfraStop® Radiant Barrier Foil Insulation underneath sub-floors is an excellent way to stop radiant heat loss to basements, increase comfort, and lower utility costs. InfraStop® is safe, simple, and easy to install especially in under sub-floor applications because this is one of the few times there are no obstructions. InfraStop® is unaffected by moisture and humidity and creates an excellent vapor barrier. InfraStop® insulation provides a radiant barrier to stop heat loss and adds R-Value to existing insulation.
|Unroll InfraStop® horizontally along the floor.|
|Staple to corner joists and then again on the side of the joist as in the illustration. Make sure to insulation recesses at least 1/2" into the floor joist cavity.|
|Continue to staple along the floor ensuring that rFoil insulation is recessed into wall cavity 1/2" to 3/4".|
|Seal all joints with reflective foil insulation tape|
|Install floor deck as usual.|
