Technical Guide - Insulated Concrete Wall Forming …

1 Technical GuideVersion Pre-Finished, Stay-in-PlaceConcrete Wall FormworkNuform Building Technologies Inc. is an innov-ative quality-driven building technologiescompany. Since the introduction of CONFORM (formerly Royal Building SystemsTM) in 1992, theproduct has received global recognition for itsapproach in providing an innovative solution tothe construction a patented polymer-based stay-in-place formwork for Concrete walls. The extrudedcomponents slide and interconnect together tocreate a Concrete formwork . The result is perma-nent, attractive, andpre-finished Concrete wallsthat can be easily constructed in any climate. CONFORM is composed of numerous modularcomponents for 100mm, 150mm and 200mm (4 , 6 and 8 ) Concrete walls that can be assem-bled to suit any wall layout, whether you arebuilding a vehicle wash, an agricultural facility or alarge industrial requires no painting, and resistsultra-violet radiation.

2 The polymer components will notdecay or deteriorate over a lifespan that can bemeasured in decades. Furthermore, CONFORMis highly durable, virtually maintenance free,impervious to weather, and energy manufactured using R3 extrusiontechnology as an environmentally friendly prod-uct. The polymer components contain over 55%recycled content and are recyclable, energy effi-cient,mold and mildew resistant and offers complete design flexibility andan innovative building product that is easy tomaintain, friendly to the environment, and builtto last. Whether you area developer, contractor,architect, engineer, or designeryou can find attrac-tive and cost effective solutions for your nextproject with CONFORM.

IntroductionCONFORM uses extruded rigid polymer compo-nents that serve as a pre-finished, stay-in-placeformwork for Concrete walls including bearing walls,non-bearing walls, shear walls, retaining walls andfoundation walls. The extruded components slideand interconnect together to create a Concrete form-work that remains in place after the Concrete ispoured and cured. CONFORM provides permanent,low maintenance, interior and exterior wall finishes. Four types or thicknesses of CONFORM are avail-able: CF4 (100 mm or 4 ) CF6 (150 mm or 6 ) CF8 (200 mm or 8 ) CF8i (200 mm or 8 , pre- Insulated ).

7 Refer to Table and Figure Components2. CONFORM formwork (1) The CF8i components are pre- Insulated with 54 mm ( ") of polyurethane insulation. The insulation cavity is on the exterior side of the wall and is pro-tected from the interior with the non-combustible Concrete CONFORMCONFORMC oncrete Wall ThicknessSizeInsulationCF4CF6CF8CF8i(1)1 00 mm(4 )150 mm(6 )200 mm(8 )200 mm(8 )95 mm( )145 mm( )195 mm( )139 mm( )00054 mm( )2 Each type of CONFORM creates a wall formworkusing a variety of components. The two most com-monly used components, for each wall thickness,are the straight box connector and the panel 232,which are 100 mm (4") and 232 mm (9") components are used for walls of small struc-tures.

8 The various CF4 components are shown inFigure , CF6 and CF8 components are used forbearing and non-bearing walls where no thermalinsulation is required. The various CF6 componentsare shown in Figure , and the various CF8 com-ponents are shown in Figure components are used for Insulated , exterior,bearing and non-bearing walls. The various CF8icomponents are shown in Figure flexibility of the system allows for the combiningof all four types in order to accommodate a wide vari-ety of structures and construction and trim components are available to pro-vide a finishing touch to CONFORM components are available in twostandard colors: tan and whiteCF4CF6CF8CF8iFigure CONFORMFig CF4 ComponentsBox Connector: Straight Box Connector: End Box Connector: CornerBox Connector: 3-way Box Connector: 4-way Box Connector: 45 Panel 93 Panel 182 Panel 232 Spacer 49 Spacer 68 Box JoinerPanel Joiner - Main Panel Joiner - Leg StarterBasic Frame OpeningFig CF6 ComponentsBox Connector: Straight Box Connector.

It is important to note that the dimension of the panel is composed of mm for theactual panel and a mm joint gap at each side ofthe panels and spacers include a joint gapand thereforethe length of wall created by a panel orspacer is greater than the actual component , panels and spacersare named by compo-nent size and not by the wall length dimension.

10 It isessential to consider the actual wall length createdrather than the component dimension in calculatingthe length of a other components provide for corners, intersec-tions and alternate panel dimensions to suit thelocation of wall intersections, doors, and windows;and the coring is CONFORM components are cored. That is, thewebs of the profiles are punched. This allows the hor-izontal flow of Concrete between the elements. Coresare punched starting from the top of the start of thefirst core is located at 37 mm (11 2")from the top end of the component and the subse-quent cores are mm (3 1 4") apart. For stepped or slopped walls, the components areextruded longer to the nearest increment andfabricated to the exact length required, in order toalign the coring horizontally.
