Weatherking® / Plus WC Membrane Adhesive

  • Long-Term Security from Multi-Ply Construction
  • Superior Polymers & Sag Resistance
  • Reduces Risk During Application

Weatherking is a cold process modified adhesive containing advanced fiber formulations to provide superior sag resistance with exceptional weather ability. A unique blend of Styrene-Ethylene-Butadylene-Styrene and Styrene-Isoprene-Styrene (SEBS and SIS) modifiers maintain flexibility and provide excellent UV resistance and heat stability. A Weatherking roofing system is constructed with multiple plies of Garland's HPR® Tri-Base Premium, HPR Glasbase, HPR Premium Glasbase, or one of Garland’s 2-Ply modified base sheets. It can also be used with two plies of approved generic base sheets with a top ply of an approved Garland-modified membrane. The result is a high-performance, cold-applied built-up roof system with an outstanding lifespan that functions equally well on flat surfaces and slopes up to 3:12 for Weatherking and 2:12 for Weatherking Plus WC.

Long-Term Security from Multi-Ply Construction

The Weatherking system combines the strength and proven performance of a multi-ply configuration with the durability of an elastomeric roof system. It offers an effective roof replacement solution in areas with impractical hot asphalt or torch systems. This high-performance roofing system represents a concerted development effort by Garland researchers combined with years of practical problem-solving field experience.

Superior Polymers and Sag Resistance

Advanced fiber formulation provides excellent slope resistance, allowing Weatherking to be applied on slopes up to 3:12. This unique polymer blend includes both SEBS and SIS rubber, allowing Weatherking Plus to maintain flexibility and offer improved UV resistance.

Reduces Risk During Application

Applied by up-to-date, easy handling techniques, the Weatherking systems speed up installation and effectively reduce roof labor time. On small jobs, or when your Garland Representative determines that only partial roof replacement is necessary, cold-applied Weatherking systems installation costs are less since no heavy equipment or large crew is required.
