Jasno blinds are produced from basswood. This is a light but solid wood variety that can be easily machined. The louvers are quarter-sawn to provide an attractive grain structure and means that long, straight lengths can be obtained whilst distortion and twisting are kept to a minimum.

The aluminium top box can be concealed by a wooden fronting strip in the colour of the louvers. The blinds have a smooth, trapezium-shaped bottom strip that prevents damage to your windowsill.
