The aerated concrete demising wall protected the remaining portion of the building, enabling it to maintain its structural products are non-combustible.

2 So in the case offire, Aercon will help preventthe spread of the fire to otherrooms. When exposed to afire, no toxic gases or vaporsare emitted from systems such as inte-rior and exterior walls, andfloor and roof panels providetremendous fire rated assem-blies in all types of and multifamily;townhouses; commercial, pub-lic and industrial buildings allbenefit from the extraordinaryfire ratings provided by Aercon products. A uniqueproperty of Aercon is that itcontains water in crystallineform, which acts as a heat sink,absorbing heat and changinginto steam.

3 Aercon s porousstructure allows this steam toescape without causing surfacespalling. The following sections describethe numerous and diverse sys-tems which can be used in firerated applications to providesuperb systems can be con-structed using blocks, panelsor a combination of these are solid elementswith very simple connectiondetails, the ease of construc-tion helps to ensure a mono-lithic, highly the specific details andrequirements of each systemthat is available, please see thereferenced document.

6 Exceptional perfor-mance when exposed to fire , Aercon products are the idealsolution for a multitude ofsuperstructures and interiorspaces that require a fire rat-ing. Whether it s blocks orpanels, Aercon can be usedas fire separation wallsbetween townhouses, condo-miniums, apartments and other multifamily is also appropriate forhotels, motels, dormitories,assisted-living facilities, hospi-tals, prisons, jails, detentioncenters, schools, movie the-atres, exit corridors, shaftwalls, and stairwell uses include electri-cal rooms, mechanical rooms,computer rooms.

7 Communica-tions equipment rooms, flam-mable materials storage, docu-ment storage, warehouses,laundry rooms, boiler rooms,maintenance shops, emer-gency generator rooms, pro-duction control rooms, sprin-kler control rooms and inciner-ator products can be usedas the primary load resistingstructural system in addition tobeing used as cladding toincrease the fire rating of studwalls and to protect othermaterials such as bearing or non-load bear-ing; interior or exterior; single-story or multi-story; if you havea fire hazard, Aercon can pro-vide a system to contain it.

10 Inaddition to serving as thestructural floor system, Aercon floor panels also pro-vide any fire protection thatmay be required. The integralfire rating of Aercon floorpanels eliminates the need forany ancillary materials or coat-ings to achieve a fire resistantassembly. A basic 6 inch thickfloor panel system has a 4 hourfire Resistance rating per ULK909. For an assembly to beconsidered restrained merelyrequires that a concrete ringbeam, also referred to as abond beam, be poured aroundthe perimeter of the floor sys-tem, with the inclusion of rein-forcing steel in the ring beamand in the grouted key the concrete and groutpours are integral componentsof the structural system, oncethey are completed, so is thefire rated assembly.
