How Cork Spray Performs: The Facts That Matter

Real results. Tested performance. Backed by nature.

At Kliu Cork, we don’t just talk about what cork spray can do—we prove it. Our cork spray has been lab-tested for insulation, soundproofing, flexibility, water resistance, and more. Whether you’re a homeowner, contractor, or architect, these results show why sprayed cork is a smart, high-performance solution for modern buildings.

Keeps You Cooler (or Warmer)

Thermal Insulation: Helps reduce heat transfer Think of cork like a natural thermal blanket. It slows down heat loss in the winter and keeps your building cooler in the summer. That means lower energy bills and a more comfortable space year-round.

Quieter Spaces Inside

Sound Dampening: Cuts down on noise Cork spray helps reduce outside noise—great for homes near busy streets or commercial spaces with echo issues. It works like a sound cushion on your walls or roof, absorbing unwanted sound.

Won’t Let Water In

Water Resistant: Blocks moisture, won’t absorb water After it’s applied and dried, cork spray forms a water-resistant surface that protects against rain and humidity—without trapping moisture underneath.

Stays in Place

Strong Adhesion: Bonds to most surfaces Once applied, cork spray sticks—really well. It holds tight to stucco, concrete, brick, foam, wood, and more. No peeling or flaking, even in harsh weather.

Moves with Your Building

Flexible Coating: Won’t crack as surfaces shift Buildings move and expand with heat and cold. Cork spray moves with them. It stretches instead of cracking, keeping your exterior sealed and protected.

Safer in a Fire

Fire Rated: Slows down flames While no coating is fireproof, cork adds an extra layer of fire protection. It slows down flame spread and doesn’t give off toxic fumes.

Breathable Barrier

Moisture Control: Lets vapor out, keeps rain out Cork spray creates a breathable surface. It stops water from getting in, but still lets moisture escape—so your walls stay dry inside.

Built to Last

UV Resistant: Won’t fade or break down in sunlight Even under the Arizona sun, cork spray keeps its color and texture. It won’t chalk, peel, or degrade like traditional paint.

Good for the Planet

  • No harmful chemicals or VOCs
  • Renewable cork harvested from oak trees
  • Fully recyclable and biodegradable Choosing cork spray is a smart choice for eco-conscious builders and homeowners.
