HIGH PERFORMANCE VENTILATION LOUVRESGeneral DescriptionLouvres - <strong>High</strong> <strong>performance</strong> <strong>vent</strong> <strong>louvre</strong> with hiddenfixing for continuous appearance. All clip to blade andclip to mullion fixings to be aluminium allow 6063 T6 topre<strong>vent</strong> possible bi-metallic reaction. Weatherabilityclassification nomenclature (from results obtained fromthe Building Services Research and InformationAssociation) should be as follows below.Doors - <strong>High</strong> quality extruded aluminium door designedwith bespoke extrusions especially for the purpose of<strong>louvre</strong>s. Hinge type and lock may be specified to suitexact customer requirement. Standard ironmongeryEuro-profile mortice deadlock complete with singlecylinder and escutcheons, handles integral with thealuminium frame.Product - VLS50XHP/DF - high <strong>performance</strong> 50mm double bank.Material - All material manufactured from aluminium alloy toBS1474 grade 6063 T6 inclusive of blade, mullion, clipsand keys.Blade pitch - 50mm pitch with aerodynamically contoured bladewith dynamic angles of incidence to aid airflow whilstpre<strong>vent</strong>ing rain ingress.Special features - Louvre blades shall be extruded to ensure themost advantageous profile for the minimum pressure lossespossible with maximum weatherability; ensuring air flow isnot split and turbulence is kept to the absolute minimum.The blade shall be clipped to an all aluminium mullionconstruction and shall support the blade locally over notless than 25mm width per clip for strength whilst stillallowing for thermal expansion.
