Concrete stonework units (CMU) and also insulated concrete form (ICF) walls have several features in common: energy-efficiency, durability, and great indoor eco-friendly quality (IEQ). However, ICF is quicker and easier to install compared to CMU, which saves time and also money.

CMU and also ICF space mass wall systems provided in energy-efficient commercial and residential construction. Fixed walls administer energy efficiency through mass, fairly than insulative values. The massive of the wall surface system shop energy throughout the day and releases it transparent the night, which provides mass walls, favor CMU and also ICF, an excellent choice in hot and humid conditions.

Both CMU and also ICF wall systems strive to develop durable frameworks that space resistant to wind, moisture, fire, rot, and mold. CMU and also ICF wall surface systems likewise aim because that suburb indoor environmental quality (IEQ). IEQ consists of the air quality, lighting, heat conditions, and ergonomics inside a building. Terrific IEQ protects human health, boosts quality the life, and reduces stress and also potential injuries.

The straightforward Advantage that ICF over CMU Construction

There is one significant difference in between ICF and CMU construction. Structure with insulated concrete forms, like theFox Blocks, is faster and also simpler 보다 CMU construction. Therefore, ICF wall systems conserve money, reduce labor, and lessen construction risks end CMU wall systems and include interior and also exterior constant insulation and 8” on center full height furring for drywall and also exterior end up attachment..

What is Concrete masonry Units (CMU) Construction?


The very first use the the modern-day concrete block remained in 1830. However, in the joined States, it was not commonly used till the very first half the the 20th century. Three situations advocated the rise in CMU construction: the 1904 St. Louis Louisiana purchase Exposition (St. Louis world’s Fair) that advocated concrete block construction, the advancement of concrete block machinery, and also the development of a residential Portland cement industry. End the decades, the an easy design of CMU has actually not changed. CMU is concrete block do from Portland cement, aggregates like rock and quartz, and water. The block come in an assortment that shapes and also are hole or solid, v two or three cores or voids.

Advantages the CMU Construction

There room several advantages of CMU construction, including:

CMUs are resistant to moisture, rot, and also mold and are durable.CMUs room fireproof and also can act as a firewall in between rooms or structures. CMUs room pest-resistant.CMUs are a great sound-proofing material.

Disadvantages the CMU Construction

Despite that advantages, CMU construction has part drawbacks, together well. Unfortunately, the style of CMU has not retained up with the boost in demands on wall surface systems. Because that the previous 50 years, architects and also builders have actually aimed to improve the durability, energy-efficiency, and also fire and wind resilience of wall surface systems. Contemporary wall solution must additionally give the citizens a high level of IEQ.

Instead of enhancing the particular design that CMUs to accommodate these demands, builders and also designers opted to add brand-new components, extra layers, and much more steps come CMU construction. These procedures have complex the building procedure and result in an ext time and also money, and also a higher chance for errors during the constructing of a CMU wall surface assembly.

CMU illustration is an additional problem. CMUs have actually an commercial look unless a facing, prefer stucco, is applied over them.

What is Insulated Concrete forms (ICF) Construction?


Insulated concrete creates were first developed in Belgium in 1937 by Swiss nationals august Schnell and also Alsex Bosshard. The initial function of ICFs to be to produce a fast, cost-effective, and solid construction method using greatly unskilled labor. It is registered of the an initial modern patent applications ICF, however, didn’t take place until the late 1960s.

Today’s ICFs room cast-in-place concrete walls, inserted between two class of insulation. The R-values because that ICF construction vary with the kind of ICF and thickness of the foam. Fox block exceed ASHRAE/ANSI 90.1 power code requirements and also are an example of an excellent energy-efficient ICF product.

Insulated concrete form walls are built by dry-stacking increased polystyrene foam panels or interlocking hollow extruded polystyrene foam come a wall’s length. The develops are reinforced and also braced. Climate concrete is put into the EPS forms.

The benefits of ICF end CMU Construction


The goals of both ICF and CMU wall surface systems space to produce durable, energy-efficient, storm- and fire-resilient wall assemblies. The two wall assemblies likewise aim to develop a comfortable and also healthy setting for the inhabitants of the building or home.

However, similarities in between ICU and also CMU component ways in the ease and efficiency the the two building methods. Insulated concrete type takes half the time to build over concrete masonry unit walls. There space a few reasons why CMU walls take much longer to construct 보다 ICF walls.

CMU walls need the location of mortar between all horizontal and also vertical joints and then must be finished. ICF wall surfaces are put together like a lego. No mortar, extra devices needed.Sizing and handling, 1 ICF block is same to 6 CMU blocks at a fraction of the weight.Unlike ICF walls, a CMU wall needs an application of insulation. Using insulation end the concrete masonry wall involves a second trade come the job site. The second trade adds one an ext day of i have lot of money labor come the wall construction project.A concrete masonry wall often calls for the environment of an air and moisture barrier, which adds another trade and an ext labor to the wall construction project.

In the video below, a team of 9 an initial time ICF installers puts up more wall than developed masonry crew averaging over 20 guys on this 100,000 sq ft school. That"s a 50% reduction in man hours ICF VS CMU.

The Fox Block collection Insulated Concrete Forms


The Fox Block collection concrete type wall system contains two piece of 1.5 pcf density modified two ⅝ inches expanded polystyrene (EPS) foam panels. The panels are locked six to eight customs apart through molded plastic ties make of polypropylene (PP) regrind resin.

Utilizing the Fox Block collection creates one energy-efficient, moisture-,disaster-, and also pest-resistant wall surface system. Fox Blocks additionally ensure fantastic indoor ecological quality in the adhering to ways:

The Fox Block wall surface system consists of a vapor retarder which guarantee a moisture-resistant wall.Fox Blocks, through steel reinforced concrete, space disaster-resistant and also can withstand tornado and hurricane winds of end 200 MPH and projectile debris traveling over 100 MPH.Fox Blocks are durable and resistant to termites and also rot.Fox Blocks create a quiet and also healthy setting for the citizens of the building.

Importantly, the Fox Block series is quick and also easy to install, contrasted to CMU construction, i m sorry saves builders time and also money. The Fox Block is an all in one wall assembly.

Select Fox blocks ICF over the CMU Alternative

Fox Block wall systems incorporate five building and construction steps into one, consisting of structure, insulation, air barrier, vapor retarder, and attachment. This attribute significantly speeds up project distribution by remove the need to coordinate many trades, when achieving all of the wall surface systems objectives.
