2 New Products to Improve Productivity

By Johns Manville.  

DynaSet 1K and 1-Part PermaFlash,  join Johns Manville’s extensive line of bituminous membranes.  

Johns Manville has plenty of experience with formulating and producing commercial roofing systems that last. Now, they can boast an even wider selection of modified bitumen that saves time on the roof while delivering an excellent finished result with the inclusion of DynaSet 1K and 1-Part PermaFlash to their extensive offerings.  

Product Manager Jacob Heaps said, “ DynaSet 1K is a great adhesive option when there are concerns about solvents or odors on a job site, and having the moisture-cure properties means adhesion isn’t impacted by moisture that may be present in concrete roof decks. Using it to adhere an SBS vapor retarder is a great option to help alleviate concerns of moisture entering the roof assembly from underneath. The 1-Part PermaFlash product will eliminate the need to mix components on site, allowing for a more efficient install around flashings.” 

DynaSet 1K 

DynaSet 1K is a one-part, solvent-free, moisture-curing adhesive designed to install JM SBS membranes. DynaSet 1K is available in a five-gallon pail (45 pounds). It can be installed using traditional, cold-adhesive application methods or can be applied in a ribbon application to allow for venting moisture below SBS vapor retarders in bituminous and single-ply systems. The moisture-cure properties provide excellent green strength and a quick set-up during install, and potential ambient moisture in concrete decks will not adversely impact the adhesive’s properties. This allows the contractor to better set schedules with a lower risk of variable measurements of moisture in the concrete, which can cause project delays. 

1-Part PermaFlash 

1-Part PermaFlash is a one-part, elastomeric, liquid-applied flashing material designed for flashing penetrations on granulated JM bituminous membranes. 1-Part PermaFlash is available in a box with two 1-gallon pails (9lbs each) or a 5-gallon pail (45lbs). It requires no mixing of components on site, reducing the risk of operator mixing errors and helping to ensure the correct installation of the product. 1-Part PermaFlash cures to a durable elastomeric film with exceptional bonding to a variety of penetrating materials. 

The bituminous SBS system is the most customizable of our low-slope commercial roofing products, with various reinforcements and installation options to fit your project’s needs. With the new offering of DynaSet 1K moisture-curing adhesive and 1-Part PermaFlash liquid-applied flashing, we continue our commitment to offering high-quality products and services that can assist our customers in completing their roof systems efficiently.
