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

You are watching: What does cmu stand for in construction

CMU and also ICF are mass wall surface systems used in energy-efficient commercial and also residential construction. Fixed walls carry out energy performance through mass, fairly than insulative values. The mass of the wall system stores energy throughout the day and releases it throughout the night, which renders mass walls, prefer CMU and ICF, an excellent choice in hot and also humid conditions.

Both CMU and ICF wall surface systems effort to create durable frameworks that are resistant to wind, moisture, fire, rot, and also mold. CMU and ICF wall surface systems also aim for suburb indoor ecological quality (IEQ). IEQ includes the air quality, lighting, heat conditions, and also ergonomics inside a building. Wonderful IEQ protects person health, improves quality that life, and reduces stress and also potential injuries.

The an easy Advantage that ICF over CMU Construction

There is one far-ranging difference in between ICF and CMU construction. Structure with insulated concrete forms, prefer theFox Blocks, is faster and simpler than CMU construction. Therefore, ICF wall surface systems conserve money, reduce labor, and also lessen building risks over CMU wall surface systems and include interior and also exterior continuous insulation and 8” on center full height furring because that drywall and also exterior complete attachment..

What is Concrete masonry Units (CMU) Construction?


The first use the the modern concrete block was in 1830. However, in the unified States, it to be not generally used until the an initial half that the 20th century. Three situations advocated the increase in CMU construction: the 1904 St. Louis Louisiana purchase Exposition (St. Louis world Fair) that supported concrete block construction, the development of concrete block machinery, and also the formation of a residential Portland cement industry. End the decades, the basic design the CMU has actually not changed. CMU is concrete block make from Portland cement, aggregates like stone and quartz, and also water. The blocks come in one assortment the shapes and also are hole or solid, through two or three cores or voids.

Advantages that CMU Construction

There space several benefits of CMU construction, including:

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

Disadvantages of CMU Construction

Despite the advantages, CMU building has some drawbacks, together well. Unfortunately, the architecture of CMU has not preserved up through the increase in requirements on wall surface systems. For the previous 50 years, architects and builders have aimed to improve the durability, energy-efficiency, and fire and also wind resilience of wall systems. Modern wall systems must likewise give the occupants a high level that IEQ.

Instead of boosting the certain design that CMUs to accommodate this demands, builders and also designers choose to add brand-new components, extra layers, and an ext steps come CMU construction. These actions have facility the building procedure and result in much more time and also money, and also a greater chance for errors throughout the building of a CMU wall surface assembly.

CMU appearance is another problem. CMUs have an industrial look uneven a facing, like stucco, is applied over them.

What is Insulated Concrete develops (ICF) Construction?


Insulated concrete develops were first developed in Belgium in 1937 through Swiss nationals respectable Schnell and also Alsex Bosshard. The initial function of ICFs was to develop a fast, cost-effective, and solid construction technique using largely unskilled labor. It is registered of the very first modern patent applications ICF, however, didn’t happen until the late 1960s.

Today’s ICFs space cast-in-place concrete walls, inserted between two layers of insulation. The R-values for ICF building and construction vary through the type of ICF and also thickness the the foam. Fox blocks exceed ASHRAE/ANSI 90.1 energy code requirements and also are an instance of wonderful energy-efficient ICF product.

Insulated concrete type walls are constructed by dry-stacking broadened polystyrene foam panels or interlocking hole extruded polystyrene foam come a wall’s length. The forms are reinforced and braced. Climate concrete is put into the EPS forms.

The benefits of ICF end CMU Construction


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

However, similarities between ICU and also CMU part ways in the ease and efficiency that the two structure methods. Insulated concrete kind takes fifty percent the time to build over concrete stonework unit walls. There room a couple of reasons why CMU wall surfaces take much longer to construct than ICF walls.

CMU walls need the location of mortar between all horizontal and vertical joints and also then must be finished. ICF walls are put together prefer a lego. No mortar, extra tools needed.Sizing and handling, 1 ICF block is equal to 6 CMU blocks at a portion of the weight.Unlike ICF walls, a CMU wall surface needs an applications of insulation. Applying insulation end the concrete masonry wall surface involves a 2nd trade come the task site. The 2nd trade to add one an ext day of costly labor to the wall construction project.A concrete masonry wall often needs the installation of an air and moisture barrier, which adds one more trade and much more labor come the wall construction project.

In the video below, a team that 9 first time ICF installers put up much more wall than developed masonry crew averaging end 20 guys on this 100,000 sq ft school. That"s a 50% reduction in man hrs ICF VS CMU.

The Fox Block collection Insulated Concrete Forms


The Fox Block series concrete form wall system contains two pieces of 1.5 pcf thickness modified 2 ⅝ inches expanded polystyrene (EPS) foam panels. The panels space locked 6 to eight inches apart v molded plastic ties do of polypropylene (PP) regrind resin.

Utilizing the Fox Block collection creates one energy-efficient, moisture-,disaster-, and pest-resistant wall system. Fox Blocks also ensure wonderful indoor eco-friendly quality in the following ways:

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

Importantly, the Fox Block collection is quick and easy come install, contrasted to CMU construction, which saves builders time and money. The Fox Block is an every in one wall assembly.

Select Fox block ICF end the CMU Alternative

Fox Block wall systems integrate five building steps right into one, consisting of structure, insulation, air barrier, vapor retarder, and also attachment. This feature significantly increases project shipment by removed the must coordinate multiple trades, while achieving all of the wall surface systems objectives.
