Foam-Control® R-SHIELD® Siding Underlayment

An efficient solution for siding underlayment applications.

Foam-Control® R-SHIELD® Fanfold Siding Underlayment can be applied directly over existing walls providing a one step underlayment and insulation resulting in reduced material and labor costs of siding application. It is an ideal material to provide a code compliant air and weather resistant barrier and reduce energy loss through framing members.

Foam-Control® R-SHIELD® Siding Underlayment Advantages

 
  • Film-faced for toughness
  • Fanfold for easy handling
  • Levels wall surfaces
  • Air Barrier
  • Weather Resistive Barrier
  • Low water vapor permeability
  • No CFC, HCFC, HFC, or formaldehyde
  • No long-term R-value loss or thermal drift

Benefits of Foam-Control® R-SHIELD® Siding Underlayment


Foam-Control R-SHIELD Fanfold Siding Underlayment benefits such as fanfold consolidation, resistance to moisture, and high R-value make it the preferred siding underlayment solution for contractors and building owners.
