Large parking garage below Westphalia Hall B3 in DortmundYtong Multipor: The insulation system forbasement and underground parking facilitiesYtong Multipor MineralInsulation Boards areideal for a light andfriendly atmosphere -a dark "bunker appearance"is out.Underground garage ceilings anddriveways are frequently insulatedpoorly if at all. Valuable heating energyescapes through walls and ceilings.This results in a cold, unpleasantroom climate in the residentialand office rooms above. Buildingsfor the future require maximumthermal insulation and energy efficientconstruction methods. This appliesfor renovation as well as newconstruction of underground garagesand basements. In addition tothermal insulation, fire protectionplays an increasingly important rolefor basements and undergroundgarages; and this fire protectiondoes not apply only to escape andrescue routes. Non-combustibleinsulating materials which do notdevelop smoke or toxic gases in afire are being used more and morefrequently due to experience in thepast.The monolithic and mineral YtongMultipor insulating system is particularlywell suited for large areainsulation work as well as for basementor underground garage ceilingswith many angles and subdivisions.2 Underground garage/basement ceiling insulation

"Tradesmen don't like using unfamiliarmaterials ..."Prejudices and advantagesCommon underground garage insulation materials such as excelsior insulatingboards and mineral wool have been available for many years. Isn't it about timeto try something new?... new, unfamiliar and noexperienceNot entirely true!The Ytong Multipor insulating systemhas proven itself well over adecade on ceiling and walls. Ourexperienced demonstrationconsultants are available for supportfor your next project with YtongMultipor.... complicated to useNot at all!These solid non-deforming insulationboards can be glued on quicklyand reliably right down to thesmallest angle – without any drilling,anchors or screws whatsoever.More on Pages 8 – 9... certainly too expensiveOn the contrary!In addition to the material costs,minimum processing times alsoprovide clear cost advantages forcomplicated details.... not approvedSimply request!The Ytong Multipor Mineral InsulationBoards are a silicate insulatingmaterial and have a European TechnicalApproval ETA-05/ 0093 as wellas a General Construction SupervisoryApproval Z-23.11-1501.More on Page 5... what about fire protection?Very simple!The Ytong Multipor Insulating Systemconsisting of mineral insulationboards in fire classification A1,and the light mortar, is non-combustible.In the event of a fire, thesystem components do not formany toxic gases and are thereforeexceptionallysuitable for all garages and as fireprotection renovation method for"old" concrete ceilings ABPP-3383/4785-MPA BS.More on Page 6... and disposalNo problem!Ytong Multipor is not classified asspecial or hazardous waste. YtongMultipor insulation boards do notcontain any pollutants. This eliminatesthe usual disposal problemsfor insulating materials.More on Page 5Underground garage/basement ceiling insulation3

Thermal and acoustic insulation,fire protectionBuilding physicsThermal insulationYtong Multipor Mineral InsulationBoards consist of 100 % homogeneousmaterial with a thermal conductivityof λ = 0.45 W/mK over theentire board thickness. Excellentvalues can be achieved in this manner.Thermal resistance R (m 2 K)/WThickness(m 2 K)/W50 mm 1,1160 mm 1,3380 mm 1,78100 mm 2,22120 mm 2,67140 mm 3,11160 mm 3,56180 mm 4,00200 mm 4,44The gluing system prevents thermalbridges such as frequently occurwith rail or anchor systems.Minimum energy lossProtection against moistureSolid Ytong Multipor Mineral InsulationBoards not only provide excellentthermal insulation, they arealso open for vapour diffusion.This ensures that the Ytong Multiporlight mortar hardens quicklyallowing the concrete ceiling tocontinue curing.System open for vapour diffusionFire protectionThe non-combustible Ytong Multipormineral insulating boards and associatedlight mortar ensure absolutesafety for basement ceilings,driveways and below ceilings inunderground garages. Ytong Multipordoes not develop any toxic vapoursor smoke even at the highesttemperatures - a true advantagewhen trying to find the escape routewhile performing vital rescue measuresduring a fire.Absolutely non combustibleAcoustic insulationRunning engines, squeeling tiresand driving noises from cars enteringand exiting frequently lead toannoying noise levels in undergroundgarages.In comparison to concrete, whichreflects nearly all sound, YtongMultipor absorbs a portion of theacoustic energy (acoustic absorberclass D) according to DIN EN 11654and its porous material structureprovides for effective reduction ofnoise in parking building facilities.Noise absorbingFire resistant classesIn underground garages high requirementsare placed on ceilingsand walls in terms of fire protection.If supporting solid ceilings, donot provide the thickness requiredfor covering the reinforcement incompliance with DIN 4102-4 for fireprotection, they can be upgraded tothe appropriate fire resistance classby covering on the bottom with Multipormineral insulation boards(glued with Ytong Multipor lightmortar) even in minimum thicknesses.Completely safe fire protection6 Underground garage/basement ceiling insulation

In no time at all: ready to use!ProcessingPROFESSIONALTIP:We recommendwearing eye protectionwhen workingoverhead and performingsandingwork.Mix light mortar …and applyno drilling or anchoring20 kg of light mortar mixed with 8 l of water(mark on measuring bucket) yields approx. 30l of adhesive mortar.Apply over full surface and comb through withtoothed trowel (10 mm or 12 mm teeth).Thermal bridges at least 70 %.Base height of light mortar approx. 8–10 mm.This allows irregularities up to 3 mm in thesubsurface to be compensated.Position board on ceiling …press down …slide into position. Finished!Position mineral insulation board with lightmortar applied immediately on ceiling at intervalof approx. 2 cm from adjacent board.Press against ceiling surface with appropriatepressure.Press with palm of hand and slide againstpreviously glued board.Remove any mortar pressed out and therebyensure that butt joints are free of mortar.Sand down if necessaryAnd one more thing!It is not necessary to support theboards while the mortar hardens.Offset points in the insulating surface can belevelled quickly and easily with a sandingboard after setting.On walls insulated over the entirearea with Ytong Multipor Mineral InsulationBoards, we recommendapplying reinforcement plaster consistingof Ytong Multipor reinforcementmesh + Ytong Multipor lightmortar to protect against mechanicalloads.8 Underground garage/basement ceiling insulation

The surface can also be filled withYtong Multipor light mortar with a layer thickness of approx. 3 mm andpromptly floated with a felt float. If a final coat of plaster is planned,it is necessary to anchor the boards previously (one anchor per board) andapply an approx. 5 mm thick reinforcement layer consisting of Ytong Multiporlight mortar and Ytong Multipor reinforcement mesh.Bottom first. Important: No Light mortar onboard protrusion.ConnectionsConnection insulation on adjacent walls:■ Use form-fitted connection if possible■ Resilient joint seal (e.g. acrylic filler)■ Swelling tapeUnderground garage/basement ceiling insulation9
