Few building materials are as versatile as spray cork. It’s an excellent way to add effective
insulation to a building while also protecting it from water, fire, mold, and more. Additionally,
spray cork is a completely natural, non-toxic substance harvested from sustainable forests.
Even better, it can be applied to almost any surface inside and outside of a building.
Let’s Take a Closer Look at Cork
Cork is harvested from the outer bark of cork oak trees, which primarily grow in the
Mediterranean region. In fact, Portugal and Spain are the leading suppliers of cork globally. In
this region, wildfires are common, and rainfall is relatively low. This has led the cork oak to
evolve with an exceptionally thick, protective layer of bark. This bark is harvested by
specially trained experts to produce cork products. Cork is eco-friendly because the tree isn’t
harmed during the harvest. In fact, harvesting the bark helps the trees live longer. An average
cork oak can yield about 15 harvests over its 300-year lifespan. Homeowners in the USA and
Europe favor these cork products because they come from sustainably managed forests. The
cellular structure of cork resembles interlocking honeycombs with air pockets, enhancing its
insulating properties.
Applying Spray Cork on Almost Any Surface
One of the many advantages of this versatile solution is that it can be applied to nearly any
surface. It adheres easily to metal roofing and shingles. Moreover, installers can apply the
material directly to existing roofs without costly tear-offs! Besides roofing, spray cork can
cover interior floors, including laminates, ceramics, marble, composites, cement, and natural
stone. It’s also suitable for exterior walking surfaces. Additionally, spray cork can be applied
to both interior and exterior walls. This product is truly versatile.
Using Spray Cork for Structural Repairs
Traditional building materials often fail to expand and contract with temperature changes. As
the ambient temperature rises, these materials expand slightly, and as it falls, they contract.
Over time, this can cause cracks in siding, walls, and foundations. Unlike most building
materials, spray cork has the remarkable ability to expand and contract with temperature
changes without losing its integrity. Cork is naturally flexible and resilient, making it ideal for
repairing existing cracks in structures.
Adding Eco-Friendly Insulation to Buildings
No matter what climate you live in, insulation is crucial for maintaining a comfortable indoor
environment while reducing heating and cooling costs. Spray cork provides excellent
insulation due to its high resistance to heat transfer. In other words, it helps keep buildings
cooler in the summer and warmer in the winter. Spray cork is particularly ideal for
commercial buildings with metal siding as well as residential homes. Just a few millimeters of
spray cork insulation can achieve optimal insulating properties.
Waterproof Roofs and Outdoor Spaces
Cork is unique in that it offers excellent breathability while remaining waterproof. This makes
it an ideal coating for roofs. Simply spray the product directly onto an existing roof to seal it
against leaks. It can prevent new leaks or repair existing ones. Additionally, the same
waterproofing properties can be applied to other outdoor spaces like patios and balconies.
Combatting Mold and Mildew
Mold and mildew are nightmares for homeowners. No one wants to deal with the musty smell
or the health issues associated with toxic mold. Fortunately, spray cork is resistant to mold
and mildew spores, making it an ideal coating for almost any building surface. Moreover,
unlike many other building materials, spray cork contains no volatile organic compounds
(VOCs). It is completely non-toxic!
Achieving the Perfect Look
While protecting your home or commercial building is likely your top priority, maintaining
the desired aesthetic is also important. Spray cork is an incredibly attractive choice. You can
customize it in the color of your choice to match your existing decor. Spray cork is available
in a wide range of colors, allowing you to achieve the look you want for your building.
