Multifunctional and flexible:Access floor of calcium sulfate

Office areas as well as lecture halls, sur-geries, assembly halls or other commer-cially used space require more and more flexible use. The rapid development of the modern communication technology and the frequent reconfiguration of commer-cial space require quick and easy access to the free plenum under the floor for the installation of additional equipment and supply lines. This flexibility is given by an access floor system which surface can be provided with many different floor coverings.

Application

FieldsofapplicationofMEROaccessfloortype6:• officeareas• areas with required increased static

loads, in lecture and assembly halls,meeting rooms, surgeries and treat-mentrooms,constructionoffices

• as industrial floor in storage spaces,work-shopswithlightoperation,libraries

• computercentres

The access floor is available in differenttypes and systems to meet user’s require-ments,e.g.reinforcedsystemsforindustrialplantsandfactorieswithheavyduty.

Advantages

• highflexibility• easy installation of additional equip-

mentandsupplylines• variable construction heights, more

than1.000mmonrequest• hugeinstallationplenum• easyhandlingofthepanelmaterial• goodfireprotectionproperties• goodsoundabsorptionvalues• suitable for the application of various

floorcoverings

TheMEROaccessfloorsystemsare testedacc.toDINEN12825andcertifiedbyinde-pendantinstitutes.

Floor panel

The MERO floor panel type 6 consists offibre-reinforced calcium sulfate of the buil-ding material class A2 acc. to DIN 4102,part1andclassifiedA1acc.totheEuropeanstandardDINEN13501.Theemissiontestsarecarriedoutacc.toin-ternational requirements (system tests =panel+pedestal):• ASTM D 5116-97 (American Emission

Test). This Standard includes the GreenLabel, Hong Kong and refers to LEED(=LeadershipinEnergyandEnvironmentalDesign)requirement
