New standard walls up ICF requirements
A new standard covering insulating concrete forms--gaining popularity as an energy-efficient building envelope--looks to deal with the range and quantity of available products.
With more than 80 products and counting, insulating concrete forms (ICFs) are becoming increasingly popular as a way to increase the energy efficiency of residential and commercial structures. To handle the varying quality of quality of ICF offerings, ASTM International Committee E06 on Performance of Buildings has developed a new standard, ASTM E2634, Specification for Flat Wall Insulating Concrete Form (ICF) Systems.
According to Committee E06 member Sheldon Warman, the standard will impart the ICF field with minimum quality standards, ensuring that ICFs used on a structure meet requirements of building codes.
The standard applies to ICFs, which act as permanent formwork for cast-in-place reinforced concrete beams; lintels; exterior and interior, above and below grade bearing and non-bearing walls; foundation; and retaining walls. The specification is restricted to ICF systems with a resultant uniform monolithic concrete core. The standard also covers fire performance and strength.
