Application
APPLICATION
Sarnafil® S 327-60 Feltback is installed by a Sika Sarnafil Authorized Applicator. Sarnafil® S 327-60 Feltback is rolled out onto the insulation board or acceptable substrate, fastened to the roof deck with appropriate plates and fasteners, and heat-welded together by trained operators using Sika Sarnafil®’s hot-air welding equipment. Please consult Sika’s Specification or Applicator Handbook for detailed installation procedures.
