Self-adhered roofing membrane with feltbacking first of its kind!

Sarnafil, the industry-leading PVC roofing membrane company, expands its sustainable products family.

Sika Corporation’s roofing and waterproofing team is excited to announce that Sarnafil’s self-adhered membrane is now also available with a felt backing, for those customers who desire a VOC-free, adhered roofing solution but prefer a membrane with felt for a smoother appearance. The Sarnafil Self-Adhered Feltback Membrane (SAFB) is the first of its kind in the single-ply roofing industry! Sarnafil’s self-adhered bareback membrane and flashing rolls already changed the industry by offering the first fully adhered PVC roof without VOCs and odors. Now those projects that want the benefit of a felt backing, Sarnafil SAFB can offer that too!  

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. The Sarnafil SAFB membrane is ideal for this steep slope roof application. 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. Fast, easy and safe installation for any steep slope roofing application. 

Adhering roofing membranes is the application of choice for many building owners but can take more time to install. Some adhesives require multiple coats with drying times in between before the sheet can be rolled in. This can add time and cost to the project. With Sarnafil SAFB, just peel the release liner and roll out. It is just that simple!

Peel & stick: No VOCs, no odors, no mess, no delays

The absence of VOCs and odors makes Sarnafil SAFB ideal for any project, but especially occupied spaces sensitive to fumes, such as hospitals, schools and universities, 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 VP of marketing and inside sales. “Now a building owner can use either a bareback membrane 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. A complete VOC-free adhered installation.” Adhered projects need not interfere with the building occupants or require scheduling around their presence, thus avoiding delays. 

Sarnafil SAFB membrane provides other important benefits in addition to the elimination of VOCs and odors. 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 eliminate the need for shipping, storing and disposing of adhesive cans as well. 

Higher productivity

Adhering roofing membranes is the application of choice for many building owners but can take more time to install. Some adhesives require multiple coats with drying times in between before the sheet can be rolled in. This can add time and cost to the project. With Sarnafil SAFB, just peel the release liner and roll out. It is just that simple!
