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 ...
Exterior insulation and finish system (EIFS) is a general class of non-load bearing building cladding systems that provides exterior walls with an insulated, water-resistant, finished surface in an integrated composite material system. EIFS has been in use since the 1960s in North America and was first used on masonry buildings.
IFAs’ innovative nature has been recognized by publications in the concrete construction industry, [1] wall and ceiling industry, [2] door and hardware industry, [3] ICF industry, [4] and architecture industry (both in the United States [5] and Canada [6]). In 2012, Stala Integrated Assemblies obtained a United States patent for integrated ...
SIP systems were used by Woods Constructors of Santa Paula, California, in their homes and apartments from 1965 until 1984. This work was the basis for John Thomas Woods, Paul Flather Woods, John David Woods, and Frederick Thomas Woods when they used a similar concept to patent the Footing Form for Modular homes (US Patent No. 4817353) issued ...
A steel-reinforced concrete grade beam may be poured at the surface to provide ground clearance for the structure. If an insulated slab is to be poured inside the grade beam, then the outer surface of the grade beam and the rubble trench should be insulated with rigid XPS foam board, which must be protected above grade from mechanical and UV ...
Reema construction is a system of building using prefabricated reinforced concrete panels which came into being in the late 1940s and was still in use well into the 1960s. Buildings made in this way are currently (2008) very hard to obtain finance on in the UK, primarily due to potential problems with similar large panel system construction ...

A common type of insulated slab is the beam and block system (mentioned above) which is modified by replacing concrete blocks with expanded polystyrene blocks. [11] This not only allows for better insulation but decreases the weight of slab which has a positive effect on load bearing walls and foundations. Formwork set for concrete pour.
