Blade descriptions and applications.
Use in sheltered areas and where water entry will not damage the building fabric. Also used for screen walling (with blanking plates fitted) and plantroom screens.
Standard 50/75/100 Series Louvres.
A superior design providing a very high level of water protection unmatched by other single bank systems
SLH-S Storm louvre Horizontal blade
Top of the range performance louvres for use where ‘dry room’ conditions are required. Unmatched by any competitive design, offering superb aerodynamic and water rejection properties.
The vertical blade design provides exceptional resistance to wind driven rain. Ideal for areas where rain is required to be kept out of the building.
The remarkable performance is due to the carefully researched profile – this allows air to pass, but diverts and captures water particles and prevents water ingress even under the most extreme conditions.
SLV-S Storm louvres Vertical blade sight proof.
A simple ‘glaze’ in louvre, suitable for use in sheltered situations.
