What are Filler Panels?

If there is any type of gap or space between the insert and the mantel shelf and legs, we provide filler panels to fill the space. Filler panels are included with the mantel price and are not an extra cost.

What are your products made with?

Our Products are made of GFRC (Glass Fiber Reinforced Concrete)

GFRC is a combination of fine aggregate, cement, water, polymer, chemical admixtures and glass fiber. The key to GFRC is the glass-fiber reinforcement. The fibers take the place of steel in a wet-cast mix. They allow GFRC to develop much higher flexural strengths than typical wet-cast concrete, allowing you to cast thinner, lighter sections and pieces.

 

BENEFITS OF GFRC

With GFRC, concrete can be cast in thinner sections and is therefore as much as 75% lighter than similar pieces cast with traditional concrete. According to Jeff Girard’s blog post titled, “The Benefits of Using a GFRC Mix for Countertops”, a concrete countertop can be 1-inch thick with GFRC rather than 2 inches thick when using conventional steel reinforcement . An artificial rock made with GFRC will weigh a small fraction of what a real rock of similar proportions would weigh, allowing for lighter foundations and reduced shipping cost.

High strength: GFRC can have flexural strength as high as 4000 psi and it has a very high strength-to-weight ratio.

Reinforcement: Since GFRC is reinforced internally, there is no need for other kinds of reinforcement, which can be difficult to place into complex shapes.
