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

2 A uniqueproperty of Aercon is that itcontains water in crystallineform, which acts as a heat sink,absorbing heat and changinginto steam. Aercon s porousstructure allows this steam toescape without causing surfacespalling.

4 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, 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.

6 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. No addi-tional materials; no additionallabor.

8 Inorder to maintain the integrityof the overall assembly, a firerated system must be used toseal the joint or gap. There arefour primary configurations ofjoints as illustrated. The basic standard used toinvestigate products that areused in joint systems isANSI/UL 2079, Tests for FireResistance of Building JointSystems . The hourly ratingsapply only to the complete sys-tems. Individual componentsare designated for use in a spe-cific system to achieve a speci-fied rating. Each of the jointsystems identified are classi-fied as dynamic , that is, hav-ing movement capabilities. Alljoint systems are tested at theirmaximum joint width. The rat-ings for the joint systemsinstalled in walls apply wheneither face of the wall isexposed to fire . The ratings forjoint systems installed in afloor or roof apply when theunderside or ceiling surface isexposed to fire Rated Joint SystemsIV - fire Resistance06/03 / IV-11 Whenever a commodity such aspiping or electrical wiring mustpass through a fire rated ele-ment, a circular or rectangularjoint or gap is usually order to maintain the integri-ty of the overall assembly, a firerated system must be used toseal the joint or gap.

9 A firestopsystem is a specific configura-tion of items that consists of awall or floor assembly, an itemthat penetrates that wall or floorassembly, and the materialsdesigned to prevent the spreadof fire through the opening thatis created around the penetrat-ing item. There are currentlythree through-penetrationfirestop systems that can be uti-lized with Aercon walls andfloors. These are illustrated toshow the various items associ-ated with each basic standard used toinvestigate products that areused in through-penetrationsystems is ANSI/UL 1479, FireTests of Through-PenetrationFirestops . This standarddefines the criteria for hourly Fand T ratings for firestop sys-tems. The F rating criteria pro-hibits flame passage throughthe system and requiresacceptable hose stream testperformance.

10 The T rating cri-teria prohibits flame passagethrough the system andrequires the maximum temper-ature rise (on the side which isnot exposed to the fire duringtesting) to 325 F above thestarting temperature and alsorequires acceptable hosestream test performance. Theratings for firestop systemsinstalled in walls apply wheneither face of the wall isexposed to fire .
