Sprayed cork roof coatings by ThermaShield can be applied directly to a variety of building materials. You can even use it to coat shingles and plywood sheathing.

In addition, sprayed cork is an effective option for sealing up cracks and holes, as well as for preventing water damage. It also provides a barrier against temperature fluctuations. As a result, it can improve the energy efficiency of any residential or commercial building.

Thermal Regulation Benefits with Sprayed Cork Roof Coatings

Many of ThermaShield’s satisfied customers choose our sprayed cork roof coatings because of their energy efficiency. The scientific community has studied cork extensively. Time and again, cork has proven itself to be a high-performing insulator and a poor conductor of heat. This translates to superior energy efficiency for the building, and thus cost-cutting benefits for the building’s owner.

One key characteristic of ThermaShield’s unique formulation is its ability to stabilize temperatures regardless of color. Generally speaking, the peak surface temperature of a cork roof coating that is light in color is between 36 and 38 degrees Celsius. For a cork roof coating that is dark in color, the range is between 44 and 46 degrees Celsius. However, the resins found in ThermaShield’s Cool Roofing System keep the material at a stable 20 to 25 degrees Celsius. This is true regardless of color.

In addition, ThermaShield’s sprayed cork roof coating is uniquely capable of blocking heat transfer due to irradiation. This is due to the product’s emission values. These are between 0.55 and 0.59. Compare this to the emission values of standard building materials, which are between 0.82 and 0.9.

Other Advantages of Using Cork Roof Coatings

The thermal regulation and energy efficiency of our cork roof coatings aren’t the only reasons why residential and commercial building owners choose ThermaShield. Take a look at these key benefits:


Cork naturally features an anti-slip surface. As a result, ThermaShield cork spray can grip the roof without sliding.


Weight is a crucial consideration for roofing materials. Thus, cork is a clear winner, with 80% of its volume attributed to air.

Fire Retardant

Construct safer, flame-retardant buildings with ThermaShield’s sprayed cork roof coatings.

Impact Absorption

When something strikes a cork-coated surface, the force is naturally dissipated throughout the surrounding area.

Above all, cork is an eco-friendly building material. In fact, cork oak trees are never killed or damaged when the cork is harvested. As a result, this material is renewable and sustainable.
