Why ICF

Insulated concrete forms (ICF) offer numerous benefits for both builders and homeowners alike. From green building to disaster resilience, ICF homes stand a cut above traditionally constructed home. Here, our experts explain exactly why ICF should be your top choice of building material.

ENERGY EFFICIENCY

Walls with a thick concrete core, sandwiched between thick insulated panels of EPS foam, provide extreme strength and durability. This material will last for lifetimes, keeping your home stable, comfortable and energy efficient. ICF forms will reduce the cost of heating and cooling your home by up to 60% compared to a similar conventionally framed home.

icon Peace And Quiet

PEACE & QUIET

ICFs have a high STC rating which means shouting outside the walls cannot be heard. Noisy neighbors, busy streets, trains, planes, and other annoyances stop at the walls – letting you enjoy your home in peace.

icon Strong Walls

SOLID, STRONG WALLS

Monolithic walls are all poured at once and are one solid piece. Combined with the EPS foam insulation and embedded insulated plastic studs, there’s no need for this house to breathe to eliminate moisture and let in dust, dirt and allergens.

GREEN CONSTRUCTION

ICFs are green products. Once the bead is produced it is expanded using steam in special molds to create the different shapes and sizes of ICF blocks. When installed, filled with concrete, and finished inside and out, the EPS foam will not degrade or decay. It doesn’t compact or lose its insulation value and will keep insulating for hundreds of years.

COMFORT INDOORS

Insulated concrete walls protect you from heat and cold, noise, pollution, and Mother Nature herself. This keeps what’s outside where it belongs, leaving you comfortable, quiet and secure no matter the threat.

4 HOUR FIRE RATING

NUDURA ICF walls are flame resistant and provide a four-hour fire rating compared to a 20-minute rating for conventionally framed structures. This factor alone will help reduce your homeowner’s insurance costs as well as giving you and your family peace of mind.

LOWEST WASTE PRODUCT

Should say Nudura ICF’s are specially designed with a 1” repeating interlock pattern, so during the ICF construction, the least necessary is cut off.
icon Disaster

DISASTER RESILIENCE

The core of ICF walls is reinforced concrete. This provides extremely strong walls to support almost any concept or design and will withstand winds of more than 250 mph, impacts from debris, and other challenges life may throw at your home.
