Sika Corporation’s roofing and waterproofing team announced that Sarnafil’s self-adhered membrane is now available with felt backing for customers wanting a VOC-free, adhered roofing solution but prefer a membrane with felt — for a smoother appearance.  

Sika says its Sarnafil Self-Adhered Feltback Membrane is the first of its kind in the single-ply roofing industry. 

Steep Slope Applications

The Sarnafil Décor Roof System, a standing seam metal roof “look-a-like” single-ply roofing option, uses a felt-backed membrane to help hide insulation board joints and roof deck imperfections. Sika says the Sarnafil SAFB membrane is ideal for this steep slope roof application. 

Note: applying adhesive on a steep slope roof requires additional safety precautions. Falling or tipping adhesive pails or rollers is a very real concern. Sarnafil SAFB removes the risk of securing the adhesive and can be installed by simply peeling off the release liner and sticking the membrane to the substrate.  

Peel & Stick: No VOCs, No Odors, No Mess, No Delays

Due to its lack of VOCs and odors, Sika says Sarnafil SAFB is ideal for projects in spaces sensitive to fumes, such as hospitals, schools, biomedical facilities, and food and beverage manufacturing.

“The addition Sarnafil Self-Adhered Feltback Membrane really completes the self-adhered family,” says Bill Bellico, Sika Roofing’s vice president of Marketing and Inside Sales. 

“Now, a building owner can use either a bareback or feltback membrane for the deck sheet while also using the self-adhered wall flashing or the SikaRoof Flashing Adhesive DS 100 on all walls and flashings,” Bellico added. “A complete VOC-free adhered installation.”  

Because adhesive is factory-applied to the underside of the Sarnafil G 410 membrane, the additional steps and precautions needed when applying adhesive at the job site are eliminated. Self-adhered membranes also eliminate the need for shipping, storing, and disposing of adhesive cans. 

Higher Productivity

Adhered roofing membranes are a popular choice for building owners, but their installation can be time-consuming due to multiple adhesive coats and drying times, which increase project costs. In contrast, with Sarnafil SAFB, you simply peel off the release liner and roll it out.

Raising the Bar—Again

Sika says its Sarnafil Self-Adhered Feltback Membrane enhances productivity, safety, and environmental benefits, making commercial roofing systems easier and faster to install. Sarnafil’s peel-and-stick product line now includes the Self-Adhered Bareback Membrane, Self-Adhered Feltback Membrane, Self-Adhered Wall Flashing, and SarnaRoof Flashing Adhesive DS 100.
