Ure-K 15-Minute Thermal Barrier

CSI: 07 21 29 • 09 83 16

Ure-K is a spray-applied 15-minute Thermal Barrier approved to go over exposed applications of polyurethane foam in existing buildings and new construction projects as a combination system to meet mandatory code requirements. Ure-K is not foam insulation.

A Universal 15-Minute Thermal Barrier

Ure-K is made from recycled paper treated with natural flame retardants resulting in an installed product with an exposed finish that also provides acoustic and thermal benefits. Ure-K has a Natural Texture similar to K-13 and is available in four standard colors along with custom colors.

15 Minutes Makes a Difference.

Thermal Control

Ure-K is often used over foam as part of a combination system to meet high R-value requirements. At the standard 1.25” application thickness, Ure-K contributes an additional R-4.5 to the insulation system.

Sound Control

Ure-K is a monolithic exposed finish providing exceptional sound absorption in new or existing buildings. Noise control is especially crucial in meeting OSHA requirements in industrial applications.

Typical Applications

The combination of Ure-K Spray Coating and foam can be used in a variety of applications:

  • Freezers/Coolers
  • Refrigerated Warehouses
  • Metal Buildings
  • Parking Decks
  • Projects Requiring High R-values
  • Curtin Wall
  • High-Rise Buildings
  • Tilt-up, Precast & Poured-In-Place Concrete Construction


Ure-K is installed by an international network of professional contractors licensed by ICC. Ure-K fibers and water-based adhesive are applied to polyurethane foam simultaneously in separate streams through equipment especially engineered to control the adhesive/fiber mixture.

Ure-K adheres to polyurethane foam as 15-Minute Thermal Barrier. Surfaces to receive Ure-K are to be inspected prior to installation to determine if pre-treatment is required.


Ure-K should not be applied in areas where there is prolonged exposure to water or where contaminants such as flammable dust, lint, or oil mist exist.

Ure-K should not be used in areas where temperatures exceed 150°F at the surface for long durations. Do not apply Ure-K in areas where mechanical damage will result unless it is protected.

Custom Colors Available

Ure-K is available in four standard colors as well as specially-matched custom colors.
