Brock, a new class of materials referred to as porous closed-cell composites, represents the newest generation of materials for building and construction. Brock combines the beneficial properties of materials such as fiberglass, polystyrene, cork, rubber and closed - and open cell foams into a single composite without the negative traits typically associated with these materials. Finally, a healthy, durable and moisture-proof alternative to traditional building materials!

Features of Brock include:

Moisture proof, mold and mildew resistant

Brock is made of waterproof beads and an adhesive; it cannot absorb moisture and does not lose strength or structure as a result of exposure to moisture.

Insulative
R-values as high as 4.0 per inch.

Lightweight and flexible
Brock is easy to handle and install. Since it is made of resilient materials,
it is more flexible than polystyrene and does not compress like fiberglass.

Safe to handle
Brock is made of 100% synthetic, non-fibrous polymers

Easy to modify
Brock can be cut with a pocket knife or razor blade on-the-spot for customization.

Damage resistant and resilient
Brock has rebound characteristics not found in fiberglass or polystyrene. Contractors will have better yields and less waste resulting from on-site damage.

Three-dimensionally porous
Brock allows fluids (such as air or water) to move through it in all directions, minimizing the risk of moisture accumulation in or around the material and keeping the structure dry.
