WHY GRIZZLY HOMES ARE ENERGY EFFICIENT

Insulated Concrete Form (ICF) homes made by Grizzly Homes keep your family safe in the roughest of weather. Grizzly Homes can withstand tornado- and hurricane-force winds of up to 250 mph. But they are also energy efficient, helping you reduce energy costs and live a greener lifestyle.

Several components help make Grizzly Homes 60 percent more energy efficient than traditional wood frame homes, yet these concrete homes cost only four to seven percent more than a conventional residence.

Polystyrene Foam Provides Better Insulation Than Conventional Wood Frames

The polystyrene foam used to insulate the spaces within ICF walls has an R-value nearly double that of insulation used in traditional wood frame homes. Insulation’s R-value represents its ability to resist heat, keeping warm air inside the home in the winter and keeping heat out during the summer.

ICF Homes Keep Temperatures More Stable, by Design

Concrete walls also absorb heat better than traditional wooden homes, which helps eliminate temperature swings...

How Do Grizzly Homes Hold Up During Natural Disasters?

Grizzly Homes’ insulated concrete form (ICF) houses are engineered from the ground up to protect you and your family from most natural disasters, including tornados and hurricanes.

Expert Builders Create Sturdy Homes

The home’s durability begins with deep, ground-reinforced concrete foundations. The walls are constructed from sturdy insulated concrete forms. The blocks are reinforced with steel rebar and then filled with concrete.

Experts in concrete construction take care to pour the concrete fill to avoid blowouts and eliminate air pockets. Sometimes called honeycombs, these pockets occur when the concrete is poured too quickly and can compromise the strength and integrity of the walls.

Grizzly Homes walls achieve an EF-5 tornado-proof rating, able to withstand 250 mph tornado winds.

Reinforced Roofing Helps Ensure Grizzly Homes Don’t Lose Their Lids

Wind-resistant roofing with added reinforcements makes sure that the roof is as sturdy as the walls of your ICF home. Homeowners have a choice of several building materials for a tornado-proof roof, including seam metal, heavy clay or concrete tiles.

Alternatively, asphalt or composition shingles with a class-G or class-H rating can withstand winds up to 120 or 250 mph, respectively. Nearly any roofing material can be reinforced with extra fasteners and more nails to strengthen the plywood sheathing below the exterior roofing material, too.
