Polyshield Triplex is our thickest double-bubble foil/foil material featuring a foam center. The stiffer material provides an easier install and will prevent sagging. While our unique Triplex material has the same 95% reflectivity as all the other variations of bubble insulation, it provides unique properties. The XPE foam center provides a higher R-Value, sound deadening, and provides a higher level of fire safety.
