Verticle Blinds are probably the best systems for exact light control. Perfect for floor to ceiling applications or smaller installations, inside or outside recess. A very contemporary look - especially with narrower 89mm louvres.
Verticle louvres collect little dust and the aluminium headrail combined with hight grade nylon components are virtually maintenance free.
A system is available for bent as well as sloping windows. Suitable for domestic or comercial applications.
