The selection of a windowsystem which will provide thespecifier with a choice ofcontrolled ventilation, naturallighting and compatibility withbuilding structure is verycomplex. Often the specifierneeds to bring together differenttypes of window product toachieve a satisfactory balancebetween the various buildingelements. Naco, Europe'sleading designers of louvrewindow systems, havedeveloped the Weatherbetaconcept to meet modernbuilding requirements.

Weatherbeta can be used toprovide maximum controlledventilation and offers superiordesign, unrivalled quality and aperformance unmatched by anyother louvre system.

Weatherbeta is available in fullylouvred, fixed or louvred andfixed options.

The 'seal of approval' for theWeatherbeta window systemhas been its selection by manyspecifiers in different countriesfor a wide variety of buildingprojects.

Weatherbeta is a qualityengineered product whichcombines a strong aluminiumframe system with ventilatingblade holders produced fromprecision injection mouldedpolypropylene material. Thebladeholders incorporatecontinuous fins which interlockand seal to the full height of theglass and provide an effectivewiping action seal on the jambs.Ventilating blades are operatedby an overcentre locking handlewhich ensures that when closedglass to glass seal is maintained.

Materials Head, jamb, cill, mullion andtransom sections aremanufactured in aluminium alloy,extruded from 6063T6.

Finishes Mill finish, natural, bronze orblack anodised to 25 microns,or polyester powder coated in arange of different colours.

Glazing Louvred glass blades are 6mm,in clear float, stippolite obscure,wired, laminated or solar controlglasses, single glazed only.Louvre blades are alwayssupplied with the window.

Alternatively 8mm toughenedglass is available.

Extruded aluminium blades areavailable in lieu of glass.

Fixed LightsOutside glazed fixed lights canbe provided to suit projectrequirements.

Fixing materialsFor fixing to timber or metal,screws are supplied. For fixingto brickwork or concrete,screws or brackets are suppliedas required.

OperationWeatherbeta can be operatedmanually or electro-mechanically.

ManualThe standard handle is designedfor hand operation. Where 'outof reach' windows occur, droprods can be fitted to thestandard handle arrangement;the maximum length of a droprod is 1500mm.

For high level installations thestandard handle can beoperated by pole or the windowmay be supplied fitted with ahandle suitable for remotecontrol gearing.

Motorised controlsWeatherbeta is available in threedifferent types for use withelectrical control systems. AOW.Automatic opening window,designed as a fail safe openingventilator, normally used inprojects where smoke venting ofcorridors, staircases orcommunity areas is required.Smokebeta. A fail safe systemdesigned for high levelinstallations such as atria,shopping malls etc. LMC. Linearmotor control unit providingconvenient electric operation forhigh level installations .

Controls & Ancillaries Ventilation control panels areavailable for Weatherbeta.For single unit to multi-zonecontrol.

Open / close switches, roomthermostats, indoor air quality &rain sensors are also available.

Coupling compatibilityAll Weatherbeta windows aredesigned for couplinghorizontally or vertically with arange of transoms and mullions. Special pressed metal cills tovarious profiles can be supplied .

Special glazing installationsFully ventilating windows areavailable with single nib, andchannel frame profile for usewithin various glazing systems.

Insect screensInsect screens are available andare normally fitted externally withsimple clip fixings.

The sub-frame sections are ofaluminium alloy extruded6063T6 finished to match thewindow. Insect screen mesh isglass grade material finished ingrey PVC. Aluminium orstainless steel mesh is availableas an alternative.

AccessoriesExtruded aluminium louvreblades are available in lieu ofglass blades. Ventilatedwindows may be fitted with arestrictor to limit the opening orclosing of the window. Securitybars may be fitted internally onventilating~ windows. Securitybladeholders are availablesubject to project location.

FixingWindows are supplied withequal or unequal frame profilefor fixing into timber surrounds.For brick or concrete structures,unequal profile is normally usedwith fixing by means ofaluminium brackets / lugs.

SizesAny size of window can bemade to a maximum length of2400mm and a maximum heightof 2400mm. Windows areavailable in single, double ortreble panel units. Maximumlength for a single panelventilator unit is 1220mm,subject to design wind load.

Handle heights and blade banking Each ventilating panel is independently operated. Panels of more than six blades aregrouped into more than one bank and each bank is individually operated to allowprecise control.

Standard banking arrangements and handle heights are given in Tables A and B.

DescriptionAll ventilating areas have a control linkage within both jamb assemblies of eachlouvred panel:

Type of operation Standard Injection-moulded handle with over-centre locking action, for operation by hand orpole. Not suitable for gearing.

Drop-rod8mm diameter natural or black anodised aluminium drop-rods may be fitted intostandard handles, after installation, with a coupling bush.

Gearing operation Natural or black anodised aluminium lever arm, drilled to receive specialist gearing.(Gearing supplied and fixed by others).

* Vertical linking channels are always supplied withpanels having more than one bank of blades.

Operating controlAll window types

Life of operation Operating cycles, based on 700 cycles annually, have beenimposed on Weatherbetalinkages and fittings withoutvisible deterioration to surface ofsections or decline in operatingprecision and efficiency, forperiods well in excess of 30years.

RS is not available on electrically operated windows.

R.S. Number of blades operated by1 handle must not exceed 4.

Reinforced security RSgeneralThe RS security developmentis an exclusive Weatherbetaoption.

RS bladeholders have metalinserts which bond, with highimpact resistant adhesive, tothe full height of the glass and‘lock’ the glass blade into thebladeholder.

Bonding is a simple operationat time of glazing.

Every bladeholder/driveassembly is completelyprotected from hacksaw attackby insertion, duringmanufacture, of hardened steelpins.

Right up to the point of glassbreakage, the louvre blades,whether of clear or obscureglass, cannot be slid out orotherwise forcibly removed.

Because the option is equallyeffective when windows areopen or closed, a physicalobstruction to entry ismaintained while maximumventilation is available.

Burglar bars

For extra protection burglarbars can be provided. They areunobtrusive and offer a realbarrier in the event of glassbeing smashed. Burglarbars are used with standardblade holders.

The bars are manufacturedfrom 12.70mm bright drawnmild steel rod, polyesterpowder coated pale grey orto match the colour of thepanel frame.

Fitted into the channel frameon the inside, they provide apermanent form of addedsecurity.
