Rubberized adhesive resists dry-out and seals-out extreme weather.
Stronger, Longer, Rubberized Adhesive
Glue is super important in a shingle. It adheres the two shingle plies together (laminate bonds), helps prevent shingle uplift from high winds (wind seals), and keeps out wind-blown rain (rain seals).
At Malarkey, we don’t just rubberize the asphalt used in our shingles, we also rubberize the adhesive to resist dry-out and for stronger, longer protection against wind, rain, and delamination.
Adhesive Formula
Malarkey pioneered the process of combining high-grade asphalt with synthetic rubber polymers, known as SBS (Styrene-Butadiene-Styrene) to chemically rubberize the asphalt core of the shingle for greater strength and durability.
We use a similar process with our adhesive, combining asphalt with SEBS (Styrene-Ethylene-Butylene-Styrene) polymers. This process dramatically enhances asphalt’s natural stickiness for greater adhesive grip, while adding rubberlike elongation and resilience to resist thermal dry-out, enhancing both its adhesive properties to join the shingles together and cohesive properties to prevent them from separating from the roof.
Adhesive Seals by Shingle Type
Our Architectural Shingles
6 ADHESIVE SEALS
Architectural shingles, like our Highlander®, Vista®, and Legacy®, come with 6 rubberized adhesive seals including 3 laminate seals (50% more than standard shingles), 2 rain seals (double standard shingles), and a wind seal.
Our Designer Shingles
8 ADHESIVE SEALS
Designer shingles, like our Windsor®, come with 8 rubberized adhesive seals including 3 laminate seals (50% more than standard shingles), 2 rain seals (double standard shingles), and 3 wind seals (triple standard shingles).
Extreme Flexibility
Malarkey’s SEBS modified asphalt adhesive excels in the most extreme environments and conditions. It is flexible down to 0˚F (-18˚C), and ensures that the shingle seal remains intact through freeze and thaw cycles.
