Roof Coatings Made to Cool, Protect

MONDAY, JUNE 13, 2016

Rhino Linings Corp. (San Diego) has introduced a cool roof system made to improve building energy efficiency and extend the service life of new and existing roofs.

The DuraTite spray polyurethane foam (SPF) roofing system holds a UL 790 Class A fire rating and is designed to provide a lightweight insulation system over various roof constructions and configurations, according to the company.

The system offers a high R-value for superior thermal insulation, covers complex geometrical shapes and protrusions and applies directly to existing substrates in new and retrofit applications, Rhino Linings reports.

The complete system combines spray foam with a full range of acrylic, silicone, urethane and polyurea coatings for a total roofing system that insulates, seals, and protects, according to the company.

Products in this system are described as follows

  • Acrylic Coatings: DuraTite 1065 and DuraTite 1070 one-component, acrylic roof coatings demonstrate adhesion to polyurethane foam, concrete, masonry, primed metal, primed wood and primed asphalt roofs. When applied at 12 DFT (dry film thickness) and fully cured, the coatings exhibit exceptional weatherability and resistance, Rhino Linings says.
  • Silicone Coatings: DuraTite 1380 and DuraTite 1395 are high solid, one-component, silicone coatings with low VOCs and chemical and abrasion resistance. When applied, the silicone coatings form a breathable membrane, recommended for new and recoat applications over metals, single-ply membranes, masonry block, concrete and SPF roofing systems where moisture may be present, the company states.
  • Urethane Coatings:  DuraTite 1175 and DuraTite 1285 are high solid, one-component urethane coatings that can be applied in a wide range of ambient temperatures and humidity levels. Both offer impact and crack resistance. DuraTite 1285 also offers enhanced UV stability, the company says.
  • Polyurea Coatings: DuraTite 2185 is a fast set, rapid cure, 100 percent solids, two-component aluminized polyurea spray-applied lining that offers enhanced UV stability and remains flexible in cold temperatures, the company says. The product demonstrates adhesion to SPF, concrete, bitumen and asphaltic roofing felts, steel, wood and most substrates in extreme cold and warm climates.
  • Spray Polyurethane Foam: DuraTite CC 2.5, DuraTite 2.8 and DuraTite 3.0 are closed-cell polyurethane foam products that boast lightweight, seamless construction to ensure leak-proof performance, the company says.
