FOAM PLASTIC INSULATION IN CONCRETE MASONRY WALLS -

Per Building Code Requirements for Masonry Structures (ref. 8) concrete masonry veneer walls are to have a minimum specified 1 in. (25 mm) air space with special precautions to limit mortar overhangs inside the cavity to allow adequate drainage between the wythes.

Do concrete masonry walls require continuous insulation ...

Table 1 shows that in Chicago (Climate Zone 5), a flat roofed building (other than Group R) must have R25 continuous insulation and masonry walls must have R11.4 continuous insulation to comply with this table. This table is often the sources of the misconception that these elements must have continuous insulation in order to comply with the IECC.

CONCRETE MASONRY BASEMENT WALL CONSTRUCTION - NCMA

A rule of thumb for estimating the number of concrete masonry units to order is 113 units for every 100 ft 2 (9.3 m 2) of wall area. This estimate assumes the use of ⅜ in. (9.5 mm) mortar joints.

R-VALUES AND U-FACTORS OF SINGLE WYTHE CONCRETE

Single wythe concrete masonry walls are often constructed of hollow units with cores filled with insulation and/or grout. This construction method allows insulation and reinforcement to be used to increase thermal and structural performance, respectively, without increasing the wall thickness.

GROUTING CONCRETE MASONRY WALLS - NCMA

Horizontal reinforcement in concrete masonry walls can be accommodated either by saw-cutting webs out of a standard unit or by using bond beam units. Bond beam units are manufactured with either reduced webs or with “knock-out” webs, which are removed prior to placement in the wall. Pilaster and column units are used to accommodate a wall- column or wall-pilaster interface, allowing space ...

CONCRETE MASONRY IN THE 2009 EDITION OF THE IECC - NCMA

The exception allows the majority of single wythe ungrouted and partially grouted concrete masonry walls containing insulation in the ungrouted cells to comply with the IECC, regardless of that wall’s R-value. Table 2—Prescriptive Wall Insulation R-Value Requirements (ref. 1) (A) A From IECC Table 502.2(1). R-values apply only to the insulating materials used. Only the requirements for non ...
