The first expanded polystyrene ICF Wall forms were developed in the late 1960s with the expiration of the original patent and the advent of modern foam plastics by BASF. [citation needed] Canadian contractor Werner Gregori filed the first patent for a foam concrete form in 1966 with a block "measuring 16 inches high by 48 inches long with a tongue-and-groove interlock, metal ties, and a waffle ...
An integrated framing assembly (IFA) is a specialty product in insulating concrete form (ICF) construction. First developed in 2006 by Stala Integrated Assemblies, LLC, and thus also known colloquially as "Stala frames," these assemblies were designed for large commercial ICF construction.
GigaCrete PlasterMax, an LEED-qualified [5] interior wall coating, is listed as a green building material and interior finish by Architectural Record. [6] [7]GigaCrete PlasterMax is a fire-resistance rated interior wall coating for insulating concrete forms (ICF), thereby providing a fire-rated green alternative to gypsum drywall over ICF.
Cast-in-place concrete or Cast-in-situ concrete is a technology of construction of buildings where walls and slabs of the buildings are cast at the site in formwork. [1] This differs from precast concrete technology where slabs are cast elsewhere and then brought to the construction site and assembled. [ 2 ]
The overall thickness of sandwich wall panels in commercial applications is typically 8 inches, but their designs are often customized to the application. In a typical 8-inch wall panel the concrete wythes are each 2-3/8 inches thick), sandwiching 3-1/4 inches of high R-value insulating foam. The interior and exterior wythes of concrete are ...
The use of highly compressed straw bales as insulation, though uncommon, is gaining popularity in experimental building projects for the high R-value and low cost of a thick wall made of straw. "Research by Joe McCabe at the Univ. of Arizona found R-value for both wheat and rice bales was about R-2.4 (RSI-0.42) per inch with the grain, and R-3 ...
Here’s the upshot: Gold beats Bitcoin as an inflation hedge for a variety of reasons.
Typical U.S. height for panels is 8 or 9 feet (2.4 or 2.7 m). Panels come in widths ranging from 4 to 12 inches (100–300 mm) thick and a rough cost is $4–$6/ft 2 in the U.S. [5] In 4Q 2010, new methods of forming radius, sine curve, arches and tubular SIPs were commercialized. Due to the custom nature and technical difficulty of forming and ...
